• Upto 2km Range
• Operates from 3.6 - 0.9V
• Dimensions: 25 x 11mm
Features
• 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
• 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
• Auto burst mode c/w 16-bit auto 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
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
Memory
• 4352 bytes internal data RAM (256 + 4096)
• 64 kB Flash; In-system programmable in 1024-byte sec-
tors—1024 bytes are reserved in the 64 kB device
Transceiver Features
• Frequency range = 433,470,868,915MHz ISM Band
• Sensitivity = –121 dBm
• FSK, GFSK, and OOK modulation
• Max output power = +20 dBm
• RF power consumption
⇒18.5mA receive
⇒18 mA @+1 dBm transmit
⇒40mA @+13 dBm transmit
⇒100mA @+20 dBm transmit
• Data rate = 0.123 to 256 kbps
• Auto-frequency calibration (AFC)
• transmit/receive switch control
• Programmable packet handler
• TX and RX 64 byte FIFOs
• Frequency hopping capability
• On-chip crystal tuning
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% accu-
racy 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
I/O Port
• 19 or 20 port I/O (5 V tolerant except for GPIO_2)
