Product Block Diagram
Overview
The Z8F642x/Z8F482x/Z8F322x/Z8F242x/
Z8F162x devices are Flash microcontrollers based
on ZiLOG®’s advanced eZ8 8-bit microprocessor
core. The Z8 Encore!® MCU family of devices sets
a new standard for performance and on-chip
peripherals.
The Z8F642x/Z8F482x/Z8F322x/Z8F242x/
Z8F162x devices feature up to twelve channels of
10-bit A/D conversion for measuring analog
signals.
These devices include four enhanced 16-bit timer
blocks featuring PWMs and Capt ure and Compare.
Up to 24 vectored interrupts with programmable
priorities provide increased application flexibility.
The 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.
