Flash; In-system programmable in 512-byte sectors
On-Chip Debug - On-chip debug circuitry facilitates full speed, -
Digital Peripherals - 29/25/21 Port I/O; All 5 V tolerant with high sink current Hardware enhanced UART, SMBus™, and SPI™ serial ports Four general purpose 16-bit counter/timers 16-bit programmable counter array (PCA) with five capture/compare modules Real time clock capability using PCA or timer and external clock source
Supply Voltage 2.7 to 3.6 V - Typical operating current: 5 mA at 25 MHz; Typical stop mode current: Temperature range: 11 µA at 32 kHz 0.1 µA –40 to +85 °C
non-intrusive in-system debug (no emulator required) Provides breakpoints, single stepping, inspect/modify memory and registers Superior performance to emulation systems using ICE-Chips, target pods, and sockets Complete development kit
Clock Sources - Internal oscillator: 24.5 MHz with ±2% accuracy supports crystal-less UART operation External oscillator: Crystal, RC, C, or clock (1 or 2 pin modes) Can switch between clock sources on-the-fly; useful in power saving modes
