Product Block Diagram

Overview

new standard for performance and on-chip

peripherals.

8KB of Flash (or optional ROM) program memory

and 1KB register RAM

The 8K Series devices feature up to five channels

of 10-bit A/D conversion for measuring analog

signals.

These devices include two enhanced 16-bit timer

blocks featuring PWMs and Capture and Compare.

Up to 19 vectored interrupts with programmable

priorities provide increased application flexibility.

The new single-pin debugger and programming

interface simplifies code development and allows

for easy in-circuit programming.

The full-duplex UART provides serial

communications and IrDA encoding and decoding

capability.

SPI and I2C ports allow easy incorporation into

any system.
