Overview
Zilog’s Z8 Encore! XP
®
F082A Series Flash
Microcontrollers are based on Zilog’s 8-bit eZ8
CPU core. The Z8 Encore! XP F082A Series Flash
Microcontrollers set a new standard for
performance and on-chip peripherals.
This Series features 1 KB, 2 KB, 4 KB or 8 KB of
non-volatile Flash memory with read/write/erase
capability and 256 B to 1 KB of register RAM.
The Z8 Encore! XP F082A Series Flash Microcon-
trollers feature an 8-channel, 10-bit Analog-to-
Digital Converter (ADC). The ADC accepts inputs
from eight different analog input pins in both sin
-
gle-ended and differential modes. The Low-Power
Operational Amplifier (LPO) is a general-purpose
amplifier for current sense applications. An on-
chip temperature sensor allows die
temperature
measurement over a range of –40 ºC to +105 ºC.
These devices include two enhanced 16-bit timers
with capture, compare, and PWM capabilities. Up
to 20 vectored interrupts with three levels of pro
-
grammable priorities provide increased application
flexibility.
The Z8 Encore! XP F082A Series features an on-
chip Internal Precision Oscillator (IPO). The IPO
(5 MHz/32 kHz) is a trimmed clock source that
requires no
external components.
The new single-pin On-Chip Debugger (OCD) and
programming interface simplifies code
development and allows easy in-circuit
programming.
The full-duplex Universal Asynchronous Receiver/
Transmitter (UART) provides serial
communications and Infrared Data Association
(IrDA) encoding and decoding capability. The
UART Baud Rate
Generator (BRG) can be
configured and used as a basic 16-bit timer.
