System Overview             D  N ew  240-960 MHz EZRadioPRO® transceiver Power efficient on-chip dc-dc buck converter High-speed pipelined 8051-compatible microcontroller core (up to 25 MIPS) In-system, full-speed, non-intrusive debug interface (on-chip) True 10-bit 300 ksps, or 12-bit 75 ksps single-ended ADC with 16 external analog inputs and 4 internal inputs such as various power supply voltages and the temperature sensor 6-bit programmable current reference Precision programmable 24.5 MHz internal oscillator with spread spectrum technology 128 kB, 64 kB, 32 kB, or 16 kB of on-chip flash memory 8448 or 4352 bytes of on-chip RAM 128 segment LCD driver SMBus/I2C, enhanced UART, and two enhanced SPI serial interfaces implemented in hardware Four general-purpose 16-bit timers Programmable counter/timer array (PCA) with six capture/compare modules and watchdog timer function Hardware AES, DMA, and pulse counter On-chip power-on reset, VDD monitor, and temperature sensor fo r  es ig ns Si102x/3x devices are fully integrated mixed-signal system-on-a-chip MCUs. Highlighted features are listed below. Refer to Table 2.1 for specific product feature selection and part ordering numbers. Two on-chip voltage comparators 53-port I/O With on-chip power-on reset, VDD monitor, watchdog timer, and clock oscillator, the Si102x/3x devices are truly stand-alone system-on-a-chip solutions. The flash memory can be reprogrammed even in-circuit, providing non-volatile data storage, and also allowing field upgrades of the 8051 firmware. User software has complete control of all peripherals, and may individually shut down any or all peripherals for power savings. m en de d   om The on-chip Silicon Labs 2-wire (C2) development interface allows non-intrusive (uses no on-chip resources), full speed, in-circuit debugging using the production MCU installed in the final application. This debug logic supports inspection and modification of memory and registers, setting breakpoints, single stepping, run and halt commands. All analog and digital peripherals are fully functional while debugging using C2. The two C2 interface pins can be shared with user functions, allowing in-system debugging without occupying package pins. R ec Each device is specified for 1.8 to 3.8 V operation over the industrial temperature range (–40 to +85 °C). The port I/O and RST pins are tolerant of input signals up to VIO + 2.0 V. The Si102x/3x devices are available in an 85-pin LGA package that is lead-free and RoHS-compliant. See Table 2.1 for ordering information. Block diagrams are included in Figure 1.1 and Figure 1.2. N ot The transceiver's extremely low receive sensitivity (–121 dBm) coupled with industry leading +13 or +20 dBm output power ensures extended range and improved link performance. Built-in antenna diversity and support for frequency hopping can be used to further extend range and enhance performance. The advanced radio features including continuous frequency coverage from 240–960 MHz in 156 Hz or 312 Hz steps allow precise tuning control. Additional system features such as an automatic wake-up timer, low battery detector, 64 byte TX/RX FIFOs, automatic packet handling, and preamble detection reduce overall current consumption.

Fully 8051 Compatible es ig ns The Si102x/3x family utilizes Silicon Labs' proprietary CIP-51 microcontroller core. The CIP-51 is fully compatible with the MCS-51™ instruction set; standard 803x/805x assemblers and compilers can be used to develop software. The CIP-51 core offers all the peripherals included with a standard 8052. 1.2.2. Improved Throughput D The CIP-51 employs a pipelined architecture that greatly increases its instruction throughput over the standard 8051 architecture. In a standard 8051, all instructions except for MUL and DIV take 12 or 24 system clock cycles to execute with a maximum system clock of 12–24 MHz. By contrast, the CIP-51 core executes 70% of its instructions in one or two system clock cycles, with only four instructions taking more than four system clock cycles. 1 2 2/3 3 Number of Instructions 26 50 5 14 3/4 4 4/5 5 8 7 3 1 2 1 fo r Clocks to Execute N ew The CIP-51 has a total of 109 instructions. The table below shows the total number of instructions that require each execution time. With the CIP-51's maximum system clock at 25 MHz, it has a peak throughput of 25 MIPS. 1.2.3. Additional Features m en de d The Si102x/3x SoC family includes several key enhancements to the CIP-51 core and peripherals to improve performance and ease of use in end applications. The extended interrupt handler provides multiple interrupt sources into the CIP-51 allowing numerous analog and digital peripherals to interrupt the controller. An interrupt driven system requires less intervention by the MCU, giving it more effective throughput. The extra interrupt sources are very useful when building multi-tasking, real-time systems. om Eight reset sources are available: power-on reset circuitry (POR), an on-chip VDD monitor (forces reset when power supply voltage drops below safe levels), a watchdog timer, a missing clock detector, SmaRTClock oscillator fail or alarm, a voltage level detection from Comparator0, a forced software reset, an external reset pin, and an illegal flash access protection circuit. Each reset source except for the POR, Reset Input Pin, or flash error may be disabled by the user in software. The WDT may be permanently disabled in software after a power-on reset during MCU initialization. N ot R ec The internal oscillator factory calibrated to 24.5 MHz and is accurate to ±2% over the full temperature and supply range. The internal oscillator period can also be adjusted by user firmware. An additional 20 MHz low power oscillator is also available which facilitates low-power operation. An external oscillator drive circuit is included, allowing an external crystal, ceramic resonator, capacitor, RC, or CMOS clock source to generate the system clock. If desired, the system clock source may be switched on-the-fly between both internal and external oscillator circuits. An external oscillator can also be extremely useful in low power applications, allowing the MCU to run from a slow (power saving) source, while periodically switching to the fast (up to 25 MHz) internal oscillator as needed. Rev. 1.0 29 Si102x/3x 1.3. Port Input/Output es ig ns Digital and analog resources are available through 53 I/O pins. Port pins are organized as eight byte-wide ports. Port pins can be defined as digital or analog I/O. Digital I/O pins can be assigned to one of the internal digital resources or used as general purpose I/O (GPIO). Analog I/O pins are used by the internal analog resources. P7.0 can be used as GPIO and is shared with the C2 Interface Data signal (C2D). See Section “35. C2 Interface” on page 525 for more details. The designer has complete control over which digital and analog functions are assigned to individual port pins. This resource assignment flexibility is achieved through the use of a Priority Crossbar Decoder. See Section “27. Port Input/Output” on page 351 for more information on the Crossbar.

Serial Ports es ig ns The Si102x/3x Family includes an SMBus/I2C interface, a full-duplex UART with enhanced baud rate configuration, and two Enhanced SPI interfaces. Each of the serial buses is fully implemented in hardware and makes extensive use of the CIP-51's interrupts, thus requiring very little CPU intervention. 1.5. Programmable Counter Array D An on-chip Programmable Counter/Timer Array (PCA) is included in addition to the four 16-bit general purpose counter/timers. The PCA consists of a dedicated 16-bit counter/timer time base with six programmable capture/compare modules. The PCA clock is derived from one of six sources: the system clock divided by 12, the system clock divided by 4, Timer 0 overflows, an External Clock Input (ECI), the system clock, or the external oscillator clock source divided by 8. N ew Each capture/compare module can be configured to operate in a variety of modes: edge-triggered capture, software timer, high-speed output, pulse width modulator (8, 9, 10, 11, or 16-bit), or frequency output. Additionally, Capture/Compare Module 5 offers watchdog timer (WDT) capabilities. Following a system reset, Module 5 is configured and enabled in WDT mode. The PCA Capture/Compare Module I/O and External Clock Input may be routed to Port I/O via the Digital Crossbar.

SAR ADC with 16-bit Auto-Averaging Accumulator and Autonomous Low Power Burst Mode es ig ns The ADC0 on Si102x/3x devices is a 300 ksps, 10-bit or 75 ksps, 12-bit successive-approximation-register (SAR) ADC with integrated track-and-hold and programmable window detector. ADC0 also has an autonomous low power Burst Mode which can automatically enable ADC0, capture and accumulate samples, then place ADC0 in a low power shutdown mode without CPU intervention. It also has a 16-bit accumulator that can automatically oversample and average the ADC results. See Section “5.4. 12-Bit Mode” on page 83 for more details on using the ADC in 12-bit mode. N ew D The ADC is fully configurable under software control via Special Function Registers. The ADC0 operates in single-ended mode and may be configured to measure various different signals using the analog multiplexer described in Section “5.7. ADC0 Analog Multiplexer” on page 94.

Programmable Current Reference (IREF0) om Si102x/3x devices include an on-chip programmable current reference (source or sink) with two output current settings: low power mode and high current mode. The maximum current output in low power mode is 63 µA (1 µA steps) and the maximum current output in high current mode is 504 µA (8 µA steps). 1.8. Comparators R ec Si102x/3x devices include two on-chip programmable voltage comparators: Comparator 0 (CPT0) which is shown in Figure 1.9; Comparator 1 (CPT1) which is shown in Figure 1.10. The two comparators operate identically but may differ in their ability to be used as reset or wake-up sources. See Section “22. Reset Sources” on page 278 and the Section “19. Power Management” on page 257 for details on reset sources and low power mode wake-up sources, respectively. N ot The comparator offers programmable response time and hysteresis, an analog input multiplexer, and two outputs that are optionally available at the Port pins: a synchronous “latched” output (CP0, CP1), or an asynchronous “raw” output (CP0A, CP1A). The asynchronous CP0A signal is available even when the system clock is not active. This allows the Comparator to operate and generate an output when the device is in some low power modes. The comparator inputs may be connected to Port I/O pins or to other internal signals.
