MAC
⢠128 or 192 kB flash, with optional read
protection
⢠12 kB RAM memory
⢠AES128 encryption accelerator
⢠Flexible ADC, UART/SPI/TWI serial
communications, and general purpose timers
⢠24 highly configurable GPIOs with Schmitt
trigger inputs
ï§ Industry-leading ARM® Cortex-M3 processor
⢠Leading 32-bit processing performance
⢠Highly efficient Thumb-2 instruction set
⢠Operation at 6, 12, or 24 MHz
⢠Flexible Nested Vectored Interrupt Controller
ï§ Low power consumption, advanced management
⢠Rx Current (w/ CPU): 26 mA
⢠Tx Current (w/ CPU, +3 dBm TX): 31 mA
⢠Low deep sleep current, with retained RAM and
GPIO: 400 nA without/800 nA with sleep timer
⢠Low-frequency internal RC oscillator for low-
power sleep timing
⢠High-frequency internal RC oscillator for fast
(110 µsec) processor start-up from sleep
ï§ Exceptional RF Performance
