The device is factory calibrated and requires no external components to help provide a cost effective solution. To reduce current consumption and save power, the AT30TS75 features a shutdown mode that turns off all internal circuitry except for the internal power-on reset and serial interface circuits. In addition, the device features a power saving oneshot mode that allows the device to make a temperature measurement, update the temperature register and then return to shutdown mode.

Selecting PB1 instead of VDDBU provides dynamic tampering synchronized with RTCOUT (PB1) pin. This position allows a diminution of the power consumption when the button is pressed (divided by the Duty Cycle applied on RTCOUT Output signal). It is possible to use the TMP2 push button as an additional Tamper input. To use this feature, the user must use JTAG in 2-wire mode (SWIO and SWD) due to the loss of the TDO pin. In this case, TMP2 is pull-up at RTCOUT Level (PB1 pin) and can be managed dynamically synchronized with the RTCOUT pin.

It is used to check if the target has power, to create the logic-level reference for the input comparators, and to control the output logic levels to the target. It is normally fed from VDD on the target board and must not have a series resistor. 2 Vsupply 3.3V power This pin is not connected in SAM-ICE. It is reserved for compatibility with other equipment. Connect to VDD or leave open in target system. 3 nTRST TARGET RESET JTAG Reset (active-low output signal that resets the target). Output from SAMICE to the Reset signal on the target JTAG port. Typically connected to nTRST on the target CPU. This pin is normally pulled HIGH on the target to avoid unintentional resets when there is no connection. 5 TDI TEST DATA INPUT JTAG data input of target CPU (serial data output line, sampled on the rising edge of the TCK signal). It is recommended that this pin is pulled to a defined state on the target board. Typically connected to TDI on target CPU. 7 TMS TEST MODE SELECT JTAG mode set input of target CPU. This pin should be pulled up on the target. Typically connected to TMS on target CPU. Output signal that sequences the target's JTAG state machine, sampled on the rising edge of the TCK signal. 9 TCK TEST CLOCK JTAG clock signal to target CPU (output timing signal, for synchronizing test logic and control register access). It is recommended that this pin is pulled to a defined state on the target board. Typically connected to TCK on target CPU. Input Return test clock signal from the target. Some targets must synchronize the JTAG inputs to internal clocks. To assist in meeting this requirement, a returned and retimed TCK can be used to dynamically control the TCK rate. SAM-ICE supports adaptive clocking which waits for TCK changes to be echoed correctly before making further changes.

SAM4C32-EK Firmware Demonstration 4.1 SAM4C32-EK Default Application The SAM4C32-EK is delivered with a preprogrammed default application in SAM4C32 Flash memory. This application implements SAM4C32 embedded peripherals and external (on-board) peripherals as detailed in the table below. Table 4-1. SAM4C32 Embedded Peripherals Peripheral Connected to External (on-board) Peripheral Real-Time Clock (RTC) — Anti-Tamper BP3 Push Button Two-wire Interface Temperature Sensor AT30TS75 Segmented LCD Custom Atmel Display SAM4C32 Core 1 — 10-bit ADC Internal ADC channel connected to Battery Backup Power Rail (VDDBU) After the first power-up without the backup battery, the time (hour and minute) of the RTC can be configured. The Hour and Minute settings are entered using the following push buttons:  BP4 (SCROLL_UP)—sets the Hour (24H mode entries must be made)  BP5 (SCROLL_DOWN)—sets the Minute  BP6 (TMP2)—saves the Hour and Minute settings Once the time settings have been saved, BP4 (SCROLL_UP) can be used to toggle the Hour display between 12H or 24H mode. Note: RTC time configuration can be skipped by pressing BP6. Once the hour and minute have been configured, the main application on core 0 runs in an infinite loop, repeating the following steps:  Every second, the time is displayed with colon (:) icon blinking  Every fifteen (15) seconds, the VDDBU pin voltage is measured and displayed (1)  Every thirty (30) seconds, the temperature (using the AT30TS75) is measured and displayed in °C and in °F. Note: 1. On the SAM4C32-EK, the voltage measured is the VDDIO voltage minus the forward voltage of the diode in the BAT54C (D4). At startup, the main application configures the core 1 subsystem to run a CoreMark algorithm from the core 1 SRAM memories (SRAM1 and SRAM2). Once the CoreMark is finished, the result of the CoreMark (number of CoreMark/MHz) is passed to the main application using the inter-processor communication embedded in the SAM4C32. Once the result is retrieved by the main application, the result of the CoreMark is displayed and the CoreMark algorithm running on core 1 is restarted. An ammeter connected either on JP12 (VDDIN) or on JP6 (VDDCORE) can measure the active current consumption of both cores. 33 SAM4C32-EK [USER GUIDE] Atmel-11253A-ATARM-SAM4C32-EK-UserGuide_17-Sep-14 4.2 Measuring the Backup Mode Current Consumption on VDDBU The SAM4C32 has an ultra-low-power mode RTC and Supply controller allowing less than 1µA (typical) on VDDBU, with the following functions/peripherals configuration:  32.768 kHz Crystal Oscillator enabled  POR backup on VDDBU disabled  RTC running  RTT enabled on 1 Hz mode  Force wake-up (FWUP) enabled  Anti-tamper Input (TMP0) enabled To measure the current consumption on VDDBU when in backup mode, JP9 (Shutdown control) must be opened and an ammeter connected on JP8 (VDDBU) as described in the following procedure: 1. Power off the board using SW1 2. Insert the 3V lithium battery provided in the battery holder 3. Place an ammeter (with sufficient capacity to measure current lower than 1µA) on JP8 4. Power on the board using SW1 5. (optional) Set the RTC as described above 6. Press the push button BP5 (SCROLL_DOWN) to place the board in low-power mode Before shutdown, the following messages are displayed on the LCD: “ENTERING BACKUP MODE” “PRESS FWUP BP1 TO WAKE UP” “USE BP3 TO GENERATE TAMPER EVENTS” Blinking “BYE” At this point, the current consumption on the ammeter should be less than 1µA @ 25°C @ 3V. Once in backup mode, the anti-tamper pin 0 (TMP0) is enabled. The BP3 (TMP0) push button can be used to generate tamper events before waking up the board. Tamper events are registered without waking up the board. Up to 15 tamper events can be registered. To wake up the board, press BP1 (FWUP). Upon start-up, the number of tamper events and time-stamping of the tamper events are displayed on the LCD. 5.
