Overview
The Z8 Encore!
®
64K Series devices are Flash
microcontrollers based on the ZiLOG
®
eZ8 CPU.
The Z8 Encore!
®
64K Series MCU family of
devices sets a new standard for performance and
on-chip peripherals.
The Z8 Encore!
®
64K Series devices support up to
64KB of Flash (or optional ROM) program
memory and 4KB register RAM
The 64K Series devices feature up to twelve
channels of 10-bit A/D conversion for measuring
analog signals.
These devices include up to four enhanced 16-bit
timer blocks featuring PWMs and Capture and
Compare.
Up to 24 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.
Two full-duplex UARTs provides serial
communications and IrDA encoding and decoding
capability.
SPI and I2C ports allow easy incorporation into
any system.
