Introduction
Zilog’s Z8 Encore! XP® F1680 Series microcontr ollers (MCU) are based
on the 8-bit eZ8 CPU c ore and optimiz ed for l ow-power appli cati ons. The
Z8 Encore! XP F1680 Series support 1.8 V to 3.6 V operation with
extremely low Activ e, Halt, and Stop mode curr ents and an assortment of
speed and low power options. Z8F1680AN020 is the silicon used in the
board. For more information, refe r to Z8 Encore! XP
Product Specification (PS0250). The features to balance power and performance needs of applications include:
•
Wide operat ing voltage range: 1.8 V–3.6 V.
•
Active, Halt, and Stop operati onal modes with the ability to enable or
disable peripherals for power savings.

•
Oscillator control tha t determines clock source, operating speed, and
fail safe operation in addition to fast wakeup.
•
A user-controlle d Program RAM area to store interrupt service
routines (ISR) of high-fre quency interrupts. The Program RAM
mechanism ensures low average current and quick response for highfrequency interrupts.

Hardware-Suppor ted So ftware Features
Zilog’s eZ8 MCU, latest 8-bit MCU meets the continuing demand for
faster and more code-efficient microcontrollers. It executes a superset of
the original Z8® instruction set. The eZ8 MCU features include:
•
Direct register- to-regist er architecture allows each register to function
as an accumu lat or, improving execution time and decreasing the
required Program Memory.
•
Software stack a llows grea ter dep th in sub-routin e ca lls an d int errupts
more than hardware stacks.
