Si1010/1/2/3/4/5
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 or 12-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
- 768 bytes RAM 16 kB (Si1010/2/4) or 8 kB (Si1011/3/5)
Flash; In-system programmable
EZRadioPRO® Transceiver
- Frequency range = 240–960 MHz
- Sensitivity = –121 dBm
- FSK, GFSK, and OOK modulation
- Max output power = +20 dBm (Si1010/1), +13 dBm
(Si1012/3/4/5)
- RF power consumption
- 18.5 mA receive
- 18 mA @ +1 dBm transmit
- 30 mA @ +13 dBm transmit
- 85 mA @ +20 dBm transmit (Si1010/1)
- Data rate = 0.123 to 256 kbps
- Auto-frequency calibration (AFC)
- Antenna diversity and transmit/receive switch control
- Programmable packet handler
- TX and RX 64 byte FIFOs
- Frequency hopping capability
- On-chip crystal tuning
Digital Peripherals
- 12 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
power saving modes and in implementing various power
saving modes
Package
- 42-pin LGA (5 x 7 mm)
Temperature Range: –40 to +85 °C
