Introduction
Zilog’s Z8 Encore! XP
®
F1680 Series microcontrollers (MCU) are based
on the 8-bit eZ8 CPU core and 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. Z8F1680AN020 is the silicon used in the
board. For more information, refer to

F1680 Series
Product Specification (PS0250).
The features to balance power and per-
formance needs of applications include:
•
Wide operating voltage range: 1.8 V–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 (ISR) of high-frequency interrupts. The Program RAM
mechanism ensures low average current and quick response for high-
frequency interrupts.
