The full-duplex universal asynchronous receiver/transmitter (UART) is included in all Z8
Encore! XP package types. The UART supports 8- and 9-bit data modes and selectable
parity. The UART also supports multi-drop address processing in hardware. The UART
baud rate generator (BRG) can be configured and used as a basic 16-bit timer.
Two enhanced 16-bit reloadable timers can be used for timing/counting events or for
motor control operations. These timers provide a 16-bit programmable reload counter and
operate in ONE-SHOT, CONTINUOUS, GATED, CAPTURE, CAPTURE RESTART,
COMPARE, CAPTURE and COMPARE, PWM SINGLE OUTPUT and PWM DUAL
OUTPUT modes.
The Z8 Encore! XP F082A Series features 6 to 25 port pins (Ports A–D) for general- pur-
pose input/output (GPIO). The number of GPIO pins available is a function of package,
and each pin is individually programmable. 5 V tolerant input pins are available on all
I/Os on 8-pin devices and most I/Os on other package types.
The 20- and 28-pin devices support controlled current sinking output pins capable of
driving LEDs without the need for a current limiting resistor. These LED drivers are
independently programmable to four different intensity levels.
The Flash Controller programs and erases Flash memory. The Flash Controller supports
several protection mechanisms against accidental program and erasure, as well as factory
serialization and read protection.
The non-volatile data storage (NVDS) uses a hybrid hardware/software scheme to
implement a byte programmable data memory and is capable of over 100,000 write cycles.
Devices with 8 KB Flash memory do not include the NVDS feature.
