Expanded interrupt handler
Memory
-
768 Bytes internal data RAM (256 + 512)
- 8, 4, or 2 kB byte-programmable EPROM code
memory
Digital Peripherals
-
17 Port I/O with high sink current capability
- Hardware enhanced UART, SMBus™, and
enhanced SPI™ serial ports
- Four general purpose 16-bit counter/timers
• Timer 3 supports real-time clock using external clock
source
- 16-Bit programmable counter array (PCA) with three
capture/compare modules and enhanced PWM
functionality
Clock Sources
-
Two internal oscillators:
• 24.5 MHz with ±2% accuracy supports crystal-less
UART operation and low-power suspend mode with
fast wake time
• 80/40/20/10 kHz low frequency, low power operation
- External oscillator: RC, C, or CMOS Clock
- Can switch between clock sources on-the-fly; useful
in power saving modes
