Overview
Zilog’s Z8 Encore! XP
®
Z8F0823 Series Flash
microcontrollers are based on Zilog’s 8-bit eZ8
CPU core. The Z8 Encore! XP F0823 Series set a
new standard of performance and on-chip
peripherals.
The Z8 Encore! XP F0823 Series support 8 KB of
non-volatile Flash memory and 1 KB on-chip
register RAM. The Z8 Encore!
Z8F0823 Series
features up to 8 single-ended channels of 10-bit
analog-to-digital conversion.
These devices include two enhanced 16-bit
reloadable timers featuring generation of PWM
signals, and Capture and Compare capability.
Up to 18 vectored interrupts with 3 levels of
programmable priorities, providing increased
application flexibility.
The Z8 Encore! XP F0823 Series features an on-
chip internal precision oscillator (IPO) as a trim
-
mable clock source that requires no external com-
ponents. The IPO features the output frequency of
either 5 MHz or 32 kHz.
The full-duplex UART provides serial communica-
tion and IrDA encoding and decoding capability.
The UART baud rate generator (BRG) can be
configured and used as a basic 16-bit timer. The
new single-pin on chip debugger and
programming
interface simplifies code development and allows
for easy in-circuit
programming.
