Introduction
Zilog’s Z8 Encore! XP
®
F1680 Series are Flash microcontrollers based
on Zilog’s eZ8 TM CPU, the 8-bit CPU core. Optimized for low-power
applications, the Z8 Encore! XP F1680 Series support 1.8 V to 3.6 V
operation with extremely low active, halt, and stop mode currents and an
assortment of speed and low power options.
Z8F1680SJ020 is the silicon used in the board. For more details, refer to

The features available to balance power and performance needs of
applications include:
•
Wide operating voltage range: 1.8 V to 3.6 V.
•
Active, Halt, and Stop operational modes with the ability to enable or
disable peripherals for power savings.
•
Oscillator control that determines clock source, operating speed, and
fail safe operation in addition to fast wakeup.
•
A user-controlled Program RAM area to store interrupt service
routines of high-frequency interrupts. The Program RAM mechanism
ensures low average current and quick response for high frequency
interrupts.
The Z8 Encore! XP F1680 Series support up to 24 KB Flash program
memory and 2 KB register data RAM. It also supports up to 256 B Non-
Volatile Data Storage (NVDS) besides the 1 KB of Program RAM.
The Z8 Encore! XP F1680 Series feature up to eight single-ended
channels of 10-bit high speed analog-to-digital conversion with a sample
and hold circuit. It also features one low-power operational amplifier for
current sampling and two comparators. An on-chip temperature sensor
