Overview
The Z8 Encore! XP
®
4K Series devices are Flash
microcontrollers based on the ZiLOG eZ8 CPU.
The Z8 Encore! XP
®
4K Series MCU family of
devices sets a new standard for performance and
on-chip peripherals.
The Z8 Encore! XP
®
4K Series devices support up
to 4KB of Flash program memory and 1KB regis
-
ter RAM
The Z8 Encore! XP
®
4K Series devices feature up
to eight single-ended/differential channels of 10-bit
A/D conversion with 1x or 20x differential input
gain and a transimpedance amplifier for current
measurement.
An on-chip temperature sensor allows die tempera-
ture measurement over a range of –40º to +105ºC
These devices include two enhanced 16-bit timer
blocks featuring PWMs and Capture and Compare.
Up to 18 vectored interrupts with programmable
priorities provide increased application flexibility.
The Z8 Encore! XP
®
4K Series features an on-chip
Internal Precision Oscillator (5MHz/32KHz) as a
trimmable clock source that requires no external
components.
The new single-pin debugger and programming
interface simplifies code development and allows
for easy in-circuit programming.
The full-duplex UART provides serial communica-
tions and IrDA encoding and decoding capability.
