Overview
The Z8 Encore!^® 8K Series devices are Flash
microcontrollers based on the ZiLOG^® eZ8 CPU.
The Z8 Encore!^® 8K Series MCU devices sets a
new standard for performance and on-chip
peripherals.
The Z8 Encore!^® 8K Series devices support up to
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.
