OVERVIEW
ZiLOG once again delivers a new standard for
performance with its Z8 Encore! XP 4K Series Flash
microcontrollers. The Z8 Encore! XP microcontrollers
are based on the ZiLOG eZ8 core and feature an
extensive set of on-chip peripherals.
The Z8 Encore! XP
4K Series devices feature up to
eight single-ended/differential channels of sigma-delta
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 temperature measurement over a range of -40°
to +105°C.
Two enhanced 16-bit timer blocks featuring PWMs
and Capture/Compare allow you to precisely measure
system events. The devices support up to 18 vectored
interrupts with programmable priorities, effectively
increasing CPU bandwidth and increasing application
flexibility. The single-pin debugger and programming
interface simplifies code development and allows for
easy in-circuit programming, making it possible for
you to create designs faster and easier.
When you need peripheral support, you can take
advantage of features like the full-duplex UART for
serial communications and IrDA encoding/decoding
capability. The on-chip Internal Precision Oscillator
(5MHz/32KHz) can serve as a trimmable clock source
that requires no external components. ZiLOG helped
you change the rules with the original Z8 Encore!
®
Series. Now you can create new rules of your own
with the Z8 Encore! XP
4K Series of Flash
microcontrollers.
