Overview
The Z8F640x series of devices are Flash
microcontrollers based on ZiLOGâs advanced eZ8
8-bit microprocessor core. The Z8 Encore!® MCU
family of devices sets a new standard for
performance and on-chip peripherals.
The Z8F640x series features twelve channels of
10-bit A/D conversion for measuring analog
signals.
These devices include 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 provide serial
communications and IrDA encoding and decoding
capability. SPI and I2C ports allow easy
incorporation into any system.
