Safety Information
The CY8CKIT-048 PSoC® Analog Coprocessor Pioneer Kit is intended for use as a development
platform for hardware or software in a laboratory environment. The board is an open system design,
which does not include a shielded enclosure. For this reason, the board may cause interference with
other electrical or electronic devices in close proximity. In a domestic environment, this product may
cause radio interference. In such cases, the user may be required to take adequate preventive
measures. Also, this board should not be used near any medical equipment or RF devices.
Attaching additional wiring to this product or modifying the product operation from the factory default
may affect its performance and cause interference with other apparatus in the immediate vicinity. If
such interference is detected, suitable mitigating measures should be taken.
The PSoC Analog Coprocessor Pioneer Kit, as shipped from the factory, has been verified to meet
with the requirements of CE as a Class A product.
The PSoC Analog Coprocessor Pioneer Kit contains ESD-sensitive devices.
Electrostatic charges readily accumulate on the human body and any
equipment which can cause a discharge without detection. Permanent damage
may occur to devices subjected to high-energy discharges. Proper ESD
precautions are recommended to avoid performance degradation or loss of
functionality. Store unused PSoC Analog Coprocessor Pioneer Kit in the
protective shipping package.
End-of-Life/Product Recycling
The end-of-life cycle for this kit is five years from the date of manufacture mentioned
on the back of the box. Contact the nearest recycler to discard the kit.
General Safety Instructions
ESD Protection
ESD can damage boards and associated components. Cypress recommends that the user perform
procedures only at an ESD workstation. If an ESD workstation is not available, use appropriate ESD
protection by wearing an antistatic wrist strap attached to a grounded metal object.
Handling Boards
PSoC Analog Coprocessor Pioneer Kit is sensitive to ESD. Hold the board only by its edges. After
removing the board from the box, place it on a grounded, static-free surface. Use a conductive foam

Introduction
Thank you for your interest in the CY8CKIT-048 PSoC® Analog Coprocessor Pioneer Kit. This kit
enables you to evaluate and develop y12
our application using the PSoC Analog Coprocessor device family. The PSoC Analog Coprocessor
simplifies the design of sensor-based systems by delivering a scalable and reconfigurable
architecture that integrates programmable Analog Front Ends (AFEs). It has a signal processing
engine (32-bit Arm® Cortex®-M0+) to calibrate and tune the AFE in software. Additionally, the PSoC
Analog Coprocessor enables applications to send aggregated, pre-processed, and formatted sensor
data over serial communication interfaces to host processors.
Systems that use multiple analog sensors usually require multiple specialized ICs to implement the
AFE, which increases BOM cost and PCB size. Systems designed for IoT applications must
combine data from multiple sensors to enable new sensing capabilities, commonly known as sensor
fusion. Sensor fusion solutions often require custom AFEs. The PSoC Analog Coprocessor reduces
the need for specialized ICs, offering the ability to create custom AFEs in a single-chip solution.
Figure 1-1 shows the analog sensors interface on PSoC Analog Coprocessor Pioneer Kit.
The PSoC Analog Coprocessor Pioneer Kit offers footprint-compatibility with Arduino™ shields and
baseboards. This kit features five analog sensors. They are pyroelectric infrared (PIR) motion
sensor, thermistor, humidity sensor, ambient light sensor (ALS), and inductive proximity sensor
(IPS). It has an RGB LED, two user-configurable push-button switches, one reset push-button
switch, an onboard programmer/debugger with USB-UART/I2C bridge, and a Cypress F-RAM™.
This kit supports operating voltages of 1.8 V, 3.0 V, 3.3 V, or 5 V.
If you are new to PSoC Creator, see the documentation on the PSoC Creator home page. You can
also refer the application note, AN211293 – Getting Started with PSoC Analog Coprocessor, which
gives an introduction to the PSoC Analog Coprocessor.

3.1.2
Analog Sensors
Analog sensors generally come in five different types, depending on their output electrical signal:
voltage, current, resistance, capacitance, or inductance. Each sensor type requires a specific AFE
design as shown in Table 3-1. The PSoC Analog Coprocessor provides resources to build all of
these AFEs, thus reducing the BOM cost and PCB size. The PSoC Analog Coprocessor contains
opamp, comparators, programmable gain amplifiers (PGA), programmable reference block (PRB)
and analog multiplexers (AMUX), which are the building blocks of different type of AFEs.
The remaining part of this section contains details of interfacing the PSoC Analog Coprocessor with
each of the sensors mentioned in Table 3-1. For example, Interfacing with a PIR Motion Sensor on
page 23 explains how to use opamps inside the PSoC Analog Coprocessor to implement a voltage
amplifier circuit.

Interfacing with a PIR Motion Sensor
The PIR motion sensor is based on the pyroelectric effect, where certain materials generate a
voltage when exposed to infrared radiation. This radiation is the portion of the electromagnetic
spectrum that falls between microwaves and visible light. Infrared radiation has wavelengths longer
than the visible light but shorter than microwaves. Humans at normal body temperature radiate
strongest in the infrared range at an approximate wavelength of 10 µm.
The PIR motion sensor uses infrared-sensitive materials as the sensing elements. It is packaged
with a field-effect transistor (FET) in the Source Follower mode, as Figure 3-6 shows. An FET is
required to buffer the high-impedance output of the sensor element. When the sensor element is
exposed to infrared radiation, a voltage is generated across the element.
Figure 3-6. PIR Motion Sensor – Single-Element
PSoC Analog Coprocessor Pioneer Kit Guide, Doc. # 002-11190 Rev. *C
23
Kit Operation
Most of the common PIR motion sensors have two or four sensing elements. These elements are
arranged such that the voltage generated by one is subtracted by the other. This arrangement
cancels the common signal and generates a voltage only when there is a difference in the incident
infrared radiation level on the sensing elements.
Figure 3-7 shows the dual-element PIR motion sensor with the elements connected in series but
with an opposite phase, because of which it has the maximum sensitivity along a particular axis.
Figure 3-7. PIR Motion Sensor Dual-Element
The sensor package is designed to have a unique field-of-view for each element. When an IR
radiating source moves across the fields of view, the sensor generates a differential signal (see
Figure 3-8). For a 90° field-of-view or more, a Fresnel lens is mounted on the PIR motion sensor. It
improves the sensitivity and thus the detection distance.
Figure 3-8. PIR Motion Sensor Output Response
PSoC Analog Coprocessor Pioneer Kit Guide, Doc. # 002-11190 Rev. *C
24
Kit Operation
Figure 3-9 shows the PSoC Creator schematic for interfacing a PIR motion sensor with the PSoC
Analog Coprocessor.
Figure 3-9. Interfacing PSoC Analog Coprocessor with PIR Motion Sensor
The PIR motion sensor implementation on the PSoC Analog Coprocessor Pioneer Kit consists of
five stages: a bias circuit for the PIR motion sensor, a first-stage amplifier, a high-pass filter (HPF), a
second-stage amplifier, and an ADC. In the main stages of the PIR motion sensor implementation,
the two amplifiers are implemented in the PSoC Analog Coprocessor.
The PSoC Analog Coprocessor Pioneer Kit has a dual-element PIR motion sensor (ZRE200GE).
The voltage signal generated by the sensor is AC-coupled (using C48) and clamped to the internal
reference voltage generated from PVref Component. The typical sensor output voltage is in the order
of several millivolts and varies depending on the strength of the incident infrared radiation. To detect
the motion of a human body at a distance of 10 feet, a gain of >1000 is required. A single-stage
amplifier with such a high gain causes the amplifier output to saturate due to the amplification of the
input offset voltage. Thus, a two-stage amplifier is best suited for amplifying with a high gain.
The total gain is split between two stages. The first-stage amplifier uses a noninverting amplifier
configuration using an internal opamp and external gain setting resistors, R118 and R119. The
second-stage amplifier uses a PGA Component. The first-stage amplifier gain is set to 681 and the
PGA gain is set to 1 on startup. However, the second-stage amplifier gain changes depending on the
detection distance required – 3 feet, 10 feet, or 20 feet.
An HPF, made using external passive components C91 and R147, is introduced between the first
and the second amplifier stages to eliminate the offset voltage.
The PIR motion sensor and gain stages use a 1.2-V system bandgap voltage as the reference
voltage. The bandgap voltage is independent of supply voltage fluctuations and hence provides a
stable voltage reference. This voltage is generated using a programmable voltage reference
component, PVref, and is buffered using an opamp.
The output of the second-stage PGA is connected to the Scanning SAR ADC Component. The
Scanning SAR ADC results are compared against threshold values to detect the motion of an IR
emitting object.

3.1.2.2
Interfacing with an Ambient Light Sensor
An ambient light sensor (ALS) is a current sensor, which gives different current outputs based on the
intensity of incident light on the sensor. The change in the current output is measured to detect the
ambient light intensity.
Figure 3-10 shows PSoC Creator schematic to interface an ALS to the PSoC Analog Coprocessor.
Figure 3-10. Interfacing PSoC Analog Coprocessor with Ambient Light Sensor
The current output from the ALS is converted to a voltage signal using a transimpedance amplifier
(TIA). The TIA is built using one of the opamps in the PSoC Analog Coprocessor as well as external
passive components (R84, C58).
The reference voltage for the TIA is set to the 1.2 V bandgap reference. The bandgap voltage is
independent of supply voltage fluctuations and hence provides a stable voltage reference. This voltage is generated using the programmable reference Component, PVref and is buffered using an
opamp.
The output of the TIA is measured using the 12-bit Scanning SAR ADC Component with the positive
input connected to the TIA output and the negative input connected to the reference voltage of the
TIA. The Scanning SAR ADC Component is configured in the differential mode with its reference
(Vref) connected to the bandgap voltage. This gives the ADC measurement range as Vn ± Vref,
where Vn is the negative input voltage of Scanning SAR ADC. The CPU takes the output of
Scanning SAR ADC, and calculates the photodiode current and then the light illuminance value.
The PSoC Analog Coprocessor Pioneer Kit has an ambient light sensor (TEMD6200FX01) on the
board connected to the PSoC Analog Coprocessor.
For details of firmware implementation, refer to the Code Example CE211252_Ambient_Light_Sensing available in the kit installation directory.

3.1.2.3
Interfacing with a Thermistor
Temperature can be calculated by measuring the thermistor resistance. The PSoC Creator Thermistor Calculator Component simplifies the math-intensive resistance-to-temperature conversion.
Figure 3-11 shows the PSoC Creator schematic for interfacing a thermistor with the PSoC Analog
Coprocessor.
Figure 3-11. Interfacing PSoC Analog Coprocessor with a Thermistor
The PSoC Analog Coprocessor Pioneer Kit has a thermistor RT1 (B57164K103J). A 10-kΩ
reference resistor, R89 (Rref), is connected in series with the thermistor.
The thermistor and Rref are excited using a 1.2-V bandgap voltage used as a reference voltage. The
bandgap voltage is independent of supply voltage fluctuations and hence provides a stable voltage
reference. This voltage is generated using the programmable reference Component, PVref, and is
buffered using an opamp. The same bandgap voltage is used as the ADC reference. This enables
measurement in the full-scale range of the ADC and results in increased resolution of voltage
measurement.
Three voltage signals (Vtherm, Vlow, and Vhi) from the resistor divider are connected to the two
differential channels of the Scanning SAR ADC Component. The thermistor (RT) resistance is
calculated from the ADC count using the following equation:
The temperature value is then derived by passing the measured resistance to the Thermistor
Calculator component. The Thermistor Calculator component uses a lookup table method to
calculate the temperature with a resolution of 0.1 °C.

3.1.2.4
Interfacing with an Inductive Proximity Sensor
Inductive proximity sensing works on the principle of electromagnetic coupling between a sensor coil
and the metal disk to be detected. When the metal disk enters the electromagnetic field induced by a
sensor coil, some of the electromagnetic energy is transferred into the metal disk as shown in
Figure 3-12. This transferred energy causes a circulating electrical current called eddy current. The
eddy current flowing in the metal disk induces a reverse electromagnetic field on the sensor coil,
which results in a reduction of effective inductance of the sensor coil.
The sensor coil is placed in parallel with a capacitor to form a tank oscillator circuit. The reduction in
the sensor coil inductance causes a shift in the resonant frequency of the tank oscillator circuit. This
shift in resonant frequency changes the amplitude of the signal across the sensor coil. The change in
the amplitude of the sensor coil signal is measured by the PSoC Analog Coprocessor to detect the
presence of the metal disk.
Figure 3-12. Field Coupling between Sensor and Metal
The inductive proximity sensor implementation on the CY8CKIT-048 PSoC Analog Coprocessor
Pioneer Kit consists of six stages: a sensor excitation circuit, a tank circuit, a high-pass filter (HPF), a
down mixer, a rectifier and an ADC. The main stages of the inductive proximity sensing
implementation – PWM of sensor excitation circuit, down mixer, rectifier, and ADC – are
implemented in the PSoC Analog Coprocessor. Figure 3-13 shows the PSoC Creator schematic for
inductive proximity sensing.
The inductive proximity sensor on the PSoC Analog Coprocessor Pioneer Kit is an onboard coil
implemented using PCB trace; its inductance is 3 µH (L).
The inductive proximity sensor (L) in parallel with a capacitor (C80) forms a tank circuit as shown in
Figure 3-13. The tank circuit is excited using a PWM. This PWM is called Excitation PWM in
Figure 3-13. The resistor (R77) controls the excitation current of the inductive proximity sensor. The
resonant frequency (fr) of the tank circuit is determined by the following equation.
The HPF formed by the capacitor (C57) and resistor (R78) prepares the signal for the next stage. It
removes the offset voltage and biases the filtered signal to a known reference voltage generated
from PVref Component as shown in Figure 3-13.
The signal across resistor R78 is measured by passing it through a down mixer and a rectifier that
are implemented using Universal Analog Block (UAB). The output of rectifier is connected to an
ADC that is operating on synchronous clock as shown in Figure 3-13. The ADC is set to operate in

is compared against the threshold value to detect the presence of the metal disk. The threshold
value is selected such that it is less than the peak noise observed on the ADC count to avoid false
triggers.

Interfacing with a Humidity Sensor
Humidity can be measured by measuring the capacitance of a capacitive humidity sensor. A
Cypress CapSense Component is used to measure the capacitance of the humidity sensor. The
CapSense Component provides the best-in-class signal-to-noise ratio (SNR) (>5:1) for sensors with
capacitance up to 200 pF. It also provides high-performance sensing across several varying environmental factors such as temperature and humidity.

humidity sensor.
Figure 3-14. Interfacing PSoC Analog Coprocessor with a Humidity Sensor
The PSoC Analog Coprocessor Pioneer Kit has a humidity sensor (HPP801A031) and a reference
capacitor (Cref) of 180 pF. The reference capacitor, Cref, is used to calibrate the capacitance
measurement. The capacitance of the humidity sensor is calculated using the following equation:
Where, Cs is the capacitance of the humidity sensor
Cref is the capacitance of the reference capacitor
RawCountCs is the raw count obtained from the CapSense Component when the humidity sensor is
being measured.
RawCountCref is the raw count obtained from the CapSense Component when the reference capacitor is being measured.
RawCountcos is the raw count that corresponds to the offset capacitance (trace capacitance with
sensor disconnected).
COS is the offset capacitance (trace capacitance with sensor disconnected from the pin).
Humidity is calculated from the measured capacitance Cs using the following equation:
Where,
Cs is the capacitance of the humidity sensor
Cnom is the nominal capacitance of the humidity sensor
Sensitivity is the sensitivity of the humidity sensor (pF/%RH)
%RHnom is the nominal humidity value
Note that Cnom, sensitivity, and %RHnom are specific to the sensors and are provided by sensor
manufacturer. For the humidity sensor (HPP801A031) used on PSoC Analog Coprocessor Pioneer
Kit, the Cnom, %RHnom, and sensitivity are 180 pF, 55%RH and 0.31 pF/%RH respectively.

Kit Operation
The capacitance of the humidity sensor used in the code example CE211322 varies from 162 pF to
193 pF for 1% to 100% relative humidity (RH). The calibration capacitor is selected closer to the
upper range of capacitance measurement to reduce the gain error in measurement.
For details of firmware implementation, refer to the Code Example CE211322_Humidity_Sensing
available in the kit installation directory.

KitProg2
The KitProg2 block consists of an onboard PSoC 5LP (CY8C5868LTI-LP039) device, which is used
to program and debug the PSoC Analog Coprocessor. The PSoC 5LP device connects to the USB
port of a PC through a USB connector, and to the SWD and other communication interfaces of the
PSoC Analog Coprocessor. PSoC 5LP is a true system-level solution providing MCU, memory, analog, and digital peripheral functions in a single chip. The CY8C58LPxx family offers a modern
method of signal acquisition, signal processing, and control with high accuracy, high bandwidth, and
high flexibility. Analog capability spans the range from thermocouples (near DC voltages) to ultrasonic signals. For more information, refer to the KitProg2 User Guide, visit the PSoC 5LP web page
and refer to the CY8C58LPxx Family Datasheet.
3.1.4
Power Supply
The power supply system is designed to support 1.8-V, 3.3-V, or 5-V operation when supplied from
the external VIN or USB connector. The selection between 1.8 V, 3.3 V, and 5 V is made through a 4pin jumper J9. A slider switch SW4 is used to select the power supply from the voltage regulator
(Cypress PMIC - MB39C011APFT-G-BND-ERE1), USB or a 3-V coin cell. Table 3-2 lists the jumper
J9 settings for different voltages.
If the kit is used as a shield, it can be powered from the 5-V supply of the Arduino-compatible
baseboard. Figure A-3 shows the schematics of the power regulator circuit.

Hardware Functional Description
This section provides a detailed explanation of individual hardware blocks of the PSoC Analog
Coprocessor Pioneer Kit. The details of PSoC Analog Coprocessor and KitProg2 are provided in
“PSoC Analog Coprocessor” on page 20 and “KitProg2” on page 31 respectively.
A.2.1
Serial Interconnection Between PSoC 5LP and PSoC Analog Coprocessor
In addition to the use as an onboard programmer, the PSoC 5LP device is used as a USB-Serial
interface for the USB-UART bridge and the USB-I2C bridge, as shown in Figure A-1. The I2C bus
contains firmware-controlled resistive pull-ups using FETs, which can be enabled or disabled using
PSoC 5LP pins. The USB-Serial pins of the PSoC 5LP device are also available on the Arduinocompatible header; therefore, the PSoC 5LP device can be used to control Arduino shields with an
SPI/I2C/UART interface.
Note: KitProg2 firmware does not support the USB-SPI bridge functionality at present. SPI pins of
PSoC Analog Coprocessor are connected to the PSoC 5LP device for enabling SPI communication
between PSoC 5LP and PSoC Analog Coprocessor for custom PSoC 5LP applications.

A.2.2
Power Supply System
The power supply system is designed to support 1.8-V, 3.3-V, or 5-V operation when supplied from
the external VIN or USB connector. The selection between 1.8 V, 3.3 V, and 5 V is made through a 4pin jumper J9. If the board is powered from the USB connector, it provides 3.3 V and 5 V to the
Arduino-compatible power headers. The board also has a provision for a 3-V coin cell. However, the
coin cell holder is not loaded by default. If you want to use the 3-V coin cell, you should populate the
coin cell holder (BHX1-1225-SM) at the V1 position on the bottom side of PSoC Analog Coprocessor
Pioneer Kit. If the kit is used as a shield, then it can be powered from the 5-V supply of the Arduinocompatible baseboard. Figure A-2 shows the schematics of power regulator circuit. Refer to
Table 3-2 on page 31.

The voltage regulator (U3, MB39C011APFT-G-BND-ERE1) from Cypress has two channels that
provide different voltage levels. The regulator generates a constant 3.3 V on one channel. The other
channel can be configured to generate 1.8 V, 3.3 V, or 5.0 V by setting the jumper J9 to desired
position. The digital potentiometer (U12) can be used to generate voltages in the 1.8 V–3.3 V range
when powered from USB. This feature will be available in future versions of KitProg2. A 4-pin jumper
(J9) is used to select any one of the three voltage levels (1.8 V, 3.3 V, or 5.0 V) or a programmable
voltage level (1.8 V–3.3 V). VDD source selection slider switch (SW4) is used to select the power
supply from the voltage regulator, USB or the 3-V coin cell.

Current Measurement Jumper
The kit has an onboard facility to monitor both analog and digital power consumed by the PSoC
Analog Coprocessor. To measure the PSoC Analog Coprocessor power consumption, the jumper
J14 is populated in series with the power supplies (Analog/Digital) to the PSoC Analog Coprocessor
and can be used to measure current using an ammeter without the need to remove any components
from the board. The switch SW5 is provided to select between Analog/Digital power domain. The
KitProg2 on the board is also able to measure the power consumption of the PSoC Analog
Coprocessor using its internal Del-Sig ADC and SAR ADC. For this purpose, either a 1 Ohm shunt
resistor or 10 Ohm shunt resistor can be selected using the jumper J14. Connect an ammeter
between terminals 3 and 4 of the jumper J14 to measure the PSoC Analog Coprocessor current
consumption manually.

Expansion Connectors
A.2.5.1
Arduino-compatible Headers (J1 to J8, and J12)
This kit has nine Arduino-compatible headers: J1, J2, J3, J4, J5, J6, J7, J8, and J12. You can
develop applications based on the Arduino shield’s hardware. The J1 header contains I/O pins for
reset, internal reference voltage (IOREF), and power supply lines. The J2 header is an analog port
that contains I/O pins for the SAR ADC. The J3 header is primarily a digital port that contains I/O pins
for PWM, I2C, SPI, and analog reference. The J4 header is also a digital port that contains I/O pins
for UART and PWM. The J12 header is an Arduino ICSP (In-Circuit Serial Programming) compatible
header for the SPI interface. Refer to the “No Load Components” section of the Bill of Materials for
the header part number. The J5, J6, J7 and J8 headers are used to connect the PSoC Analog
Coprocessor Pioneer Kit as shield. The reset and power supply lines are routed to J5, few I/Os are
routed to J6, I2C lines are routed to J7, and UART lines are routed to J8. While using the kit as a
shield, the connectors provided with the kit can be used to provide extra clearance between the
shield and the base board.
A.2.5.2
Functionality of Header J12 (Unpopulated)
The J12 header is a 2 × 3 header that supports Arduino shields. This header is used on a small
subset of shields and is not populated on the PSoC Analog Coprocessor Pioneer Kit.
A.2.5.3
PSoC 5LP GPIO Header (J16)
An 8 × 2 header is provided on the board to bring out several pins of the PSoC 5LP device to support
advanced features such as a low-speed oscilloscope and a low-speed digital logic analyzer. This
header also contains USB-UART bridge pins and USB-I2C bridge pins that can be used when these
pins are not accessible on Arduino-compatible headers because a shield is connected. The
additional pins on this header are direct connections to the internal programmable analog logic of
PSoC 5LP. This header also has GPIOs for custom application usage.
A.2.5.4
KitProg2 Custom Application Header (J11)
A 5 × 2 header is provided on the board to bring out more GPIOs of PSoC 5LP for custom application usage. This header also brings out the PSoC 5LP programming pins and can be programmed
using MiniProg3 and 5-pin programming connector.
A.2.6
USB Mini-B Connector
The PSoC 5LP device connects to the USB port of a PC through a USB Mini-B connector, which can
also be used to power the PSoC Analog Coprocessor Pioneer Kit. A resettable fuse is used to protect the computer's USB port from shorts and overcurrent. If more than 500 mA is drawn from the
USB connector, the fuse will automatically break the connection until the short or overload is
removed.
A.2.7
Analog Sensors
Refer to the Analog Sensors chapter on page 23.
A.2.8
Pioneer Board LEDs
The Pioneer board has five LEDs. Three status LEDs (Red, Amber and Green) indicate the status of
the KitProg2. Refer to the Troubleshooting section in KitProg2 User Guide for more information on
PSoC Analog Coprocessor Pioneer Kit Guide, Doc. # 002-11190 Rev. *C
42
LED states. An amber LED indicates the status of power supplied to the kit. The kit also has a general-purpose RGB LED for user applications.
A.2.9
Push Buttons
The board contains a reset button (SW1) and two user buttons. The reset button is connected to the
RESET pin of the PSoC Analog Coprocessor and is used to reset the device. One user button
(SW2) is connected to P0[3] of the PSoC Analog Coprocessor. The other user button (SW3) is connected to P1[2] of the PSoC 5LP device. All the push buttons connect to ground on activation (active
LOW).
A.2.10
Cypress Ferroelectric RAM (F-RAM)
The PSoC Analog Coprocessor Pioneer Kit contains an F-RAM device (FM24V10-G) that can be
accessed through I2C lines P4 [0] and P4 [1] of the PSoC Analog Coprocessor. The F-RAM has a
capacity of 1-Mbit (128 KB) with an I2C speed up to 3.4 MHz. The I2C slave address of the F-RAM
device is 7 bits wide, and the two least significant bits are configurable through physical pins. These
pins are hard-wired to 00 on the board. By default, the address of the F-RAM device used on the kit
is 0x50. This address can be modified by changing the R44/R39 and R36/R37 resistor pairs. The
operating voltage range of the F-RAM is between 2 V and 3.6 V. To prevent the F-RAM from operating at voltages greater than 3.6 V, the power supply to the F-RAM is derived from the output of the
3.3-V regulator. The I2C lines are connected to the 3.3-V side of the onboard level translator to allow
the F-RAM device to communicate with the PSoC Analog Coprocessor operating at 5 V. For more
information on using the F-RAM, see Using the FM24V10 F-RAM chapter on page 44.
A.2.11
External Crystals
The PSoC Analog Coprocessor Pioneer board has a provision to use a 32.768-kHz (Y1) external
crystal for the WCO input. The WCO is used to provide an accurate low-frequency clock to PSoC
Analog Coprocessor for Deep Sleep wake up intervals, and WDT reset intervals.

A.3
Using the FM24V10 F-RAM
This section describes advanced features of the PSoC Analog Coprocessor Pioneer Kit as well as
the corresponding projects. It can be used as a reference to use these features for other applications, according to the needs of the project.
The PSoC Analog Coprocessor Pioneer board has an onboard ferroelectric RAM chip that can hold
up to 1 Mb of data. The chip provides an I2C communication interface for data access. It is hardwired to the I2C interface (P4[0] and P4[1] of the PSoC Analog Coprocessor); the same lines are
routed to the PSoC 5LP I2C interface. Because the F-RAM device is an I2C slave, it can be
accessed or shared among various I2C masters on the same lines. For more details on the F-RAM
device, refer to the device datasheet.
A.3.1
Address Selection
The slave address of the F-RAM device consists of three parts, as shown in Figure A-5: slave ID,
device select, and page select. Slave ID is an F-RAM family-specific ID provided in the datasheet of
the particular F-RAM device. For the device used on the PSoC Analog Coprocessor Pioneer board
(FM24V10-G), the slave ID is 1010b. Device select bits are set using the two physical pins A2 and
A1 in the device. The setting of these two pins in PSoC Analog Coprocessor Pioneer board is controlled by resistors R44/R39 (A1) and R36/R37 (A2). Because the memory location in the F-RAM
device is divided into two pages of 64 KB each, the page select bit is used to refer to one of the two
pages in which read or write operations will take place.
Note: The 8-pin SOIC footprint provided for the F-RAM FM24V10 device on the PSoC Analog Processor Pioneer Kit is compatible with all I2C-based F-RAM devices from Cypress (FM24Vxx, FM24CLxx, and CY15BxxxJ parts). F-RAM parts with more than 64 KB size support only four addresses
(four devices of the same type on the same I2C bus); resistors connected to A1 (R44/R39) and A2
(R36/ R37) pins can be used to select any of the four addresses. F-RAM parts with less than 64 KB
and FM24CLxx parts support eight addresses; resistors connected to A0 (R46/R47), A1 (R44/R39),
and A2 (R36/R37) pins can be used to select one of the eight addresses.

A.3.2
High-Speed Mode (HS-mode)
The FM24V10 supports a 3.4-MHz high-speed mode. A master code (00001XXXb) must be issued
to place the device into high-speed mode. Communication between the master and the slave will
then be enabled for speeds up to 3.4 MHz. A STOP condition will exit the Hs-mode. Single- and multiple-byte reads and writes are supported.

A.3.3
Write/Read Operation
The F-RAM datasheet includes details on how to perform a write/read operation with an F-RAM
device. Figure A-7 and Figure A-8 provide a snapshot of the write/read packet structure as a quick
reference.
Figure A-7. F-RAM Single-Byte and Multiple-Byte Write Packet Structure
Figure A-8. F-RAM Single-Byte and Multiple-Byte Read Packet Structure
As the figures show, operations start with the slave address followed by the memory address. For
write operations, the bus master sends the slave address and memory address followed by one or
more data bytes. Each byte of data is written to consecutive locations in the memory, and the memory generates an acknowledgement condition.
PSoC Analog Coprocessor Pioneer Kit Guide, Doc. # 002-11190 Rev. *C
46
For ‘Current Address Read’ and ‘Sequential Read’, the bus master sends only the slave address.
The memory address used is the same address that was set by the previous ‘Write’ or ‘Selective
Read’ operation. For ‘Selective Read’ operations, after receiving the complete slave address and
memory address, the memory will begin shifting data from the current address on the next clock
Note: You can communicate with the F-RAM using the Bridge Control Panel (BCP) software similar
to the way you communicate with any other I2C slave device. Refer to the KitProg2 User Guide for
more details on how to use the BCP software to communicate with an I2C slave device. Visit the
CY15FRAMKIT-001 Serial F-RAM Development Kit web page for code examples and the Arduino
library for details on interfacing I2C F-RAM devices with the PSoC Analog Coprocessor family.

Migrating Projects Across Different Pioneer Series Kits
Cypress Pioneer series kits are Arduino Uno-compatible and have some common onboard peripherals such as RGB LED, CapSense and User Switch. However, the pin mapping in each of the boards
is different due to differences in pin functions of the PSoC device used. This section lists the pin
mapping of the Pioneer series kits to allow for easy migration of projects across different kits.
In some cases, the pins available on the Pioneer kit headers are a superset of the standard Arduino
Uno pins. For example, J2 contains only one row of pins on the Arduino Uno pin layout while it contains two rows of pins on many of the Pioneer series kits.
