Si1000/1/2/3/4/5
Ultra Low Power, 64/32 kB, 10-Bit ADC
MCU with Integrated 240–960 MHz EZRadioPRO^® Transceiver
Ultra Low Power: 0.9 to 3.6 V Operation
- Typical sleep mode current < 0.1 µA; retains state and
RAM contents over full supply range; fast wakeup of < 2 µs
- Less than 600 nA with RTC running
- Less than 1 µA with RTC running and radio state retained
- On-chip dc-dc converter allows operation down to 0.9 V.
- Two built-in brown-out detectors cover sleep and active
modes
10-Bit Analog to Digital Converter
- Up to 300 ksps
- Up to 18 external inputs
- External pin or internal VREF (no external capacitor
required)
- Built-in temperature sensor
- External conversion start input option
- Autonomous burst mode with 16-bit automatic averaging
accumulator
Dual Comparators
- Programmable hysteresis and response time
- Configurable as interrupt or reset source
- Low current (< 0.5 µA)
On-Chip Debug
- On-chip debug circuitry facilitates full-speed, non-intrusive
in-system debug (No emulator required)
- Provides breakpoints, single stepping
- Inspect/modify memory and registers
- Complete development kit
High-Speed 8051 µC Core
- Pipelined instruction architecture; executes 70% of instruc-
tions in 1 or 2 system clocks
- Up to 25 MIPS throughput with 25 MHz clock
- Expanded interrupt handler
Memory
- 4352 bytes internal data RAM (256 + 4096)
- 64 kB (Si1000/2/4) or 32 kB (Si1001/3/5) flash; In-system
programmable in 1024-byte sectors—1024 bytes are
reserved in the 64 kB devices

Digital Peripherals
- 19 or 16 port I/O plus 3 GPIO pins; Hardware enhanced
UART, SPI, and I²C serial ports available concurrently
- Low power 32-bit SmaRTClock
- Four general purpose 16-bit counter/timers; six channel
programmable counter array (PCA)
Clock Sources
- Precision internal oscillators: 24.5 MHz with ±2% accuracy
supports UART operation; spread-spectrum mode for
reduced EMI; Low power 20 MHz internal oscillator
- External oscillator: Crystal, RC, C, CMOS clock
- SmaRTClock oscillator: 32.768 kHz crystal or self-oscillate
- Can switch between clock sources on-the-fly; useful in
implementing various power saving modes
