Z8 ENCORE! XP® F1680 MICROCONTROLLER

nnnn

The Z8 Encore! XP® F1680 Series is rich with new features including

nnnn

1.8 V to 3.6 V operation, Program RAM (PRAM), Non-Volatile Data

nnnn

Storage (NVDS), fast 1 0-bit ADC, three enhanced 1 6-bit timers with

nnnn

Capture/Compare/PWM, Multi-Channel Timers, low-power Op-Amp,

nnnn

two Analog Comparators, a Temperature Sensor, two UARTs with Local

nnnn

Interconnect Network (LIN) and IrDA, a Master/Slave l2C, and an

nnnn

enhanced SPI interface. The Series also features an Internal Precision

nnnn

Oscillator (IPO) with ± 1 % accuracy at 25 °C and a single-pin On-Chip

nnnn

Debugger (OCD) interface for debugging and in-circuit programming.

ZiLOG MEETS YOUR DESIGN CHALLENGES

nnnn

Low Power Consumption

nnnn

The Z8 Encore! XP® Fl 680 Series supports a wide of 1.8 V to 3.6 V

nnnn

voltage range and many power saving features. The on-chip PRAM can

nnnn

be used to shadow frequently executed program code such as scanning

nnnn

and Interrupt Sevice Routines (ISR) for an additional 30% power

nnnn

savings. The unused peripheral blocks can be disabled individually by

nnnn

software. These features dramatically reduce power consumption and

nnnn

maximize the durability of a typical LiSOCl2 battery.

nnnn

Fast Sampling of Analog Signals

nnnn

The high-speed 10-bit Successive Approximation

nnnn

Register (SAR) ADC boasts a conversion time of less

nnnn

than 5 us with internal or external voltage reference.

nnnn

This feature saves power by reducing sample time and

nnnn

allowing the part to quickly return to Stop mode.

nnnn

Design Flexibility

nnnn

With up to 24 KB Flash memory, 1 KB PRAM, 2 KB

nnnn

Register RAM, 256 B NVDS, and many feature-rich

nnnn

analog/digital peripherals, the F1680 Series

nnnn

provides superior design flexibility to cope with

nnnn

increasing system complexity.

nnnn

System Cost

nnnn

The highly integrated features of the F1680 Series can

nnnn

eliminate the requirement of a crystal, real-time clock,

nnnn

Op-Amp, or Serial EEPROM thus reducing the BOM

nnnn

cost for your design.

nnnn

Better Noise Immunization

nnnn

In many applications, external signal noise can be a

nnnn

serious issue interfering with the MCU's operation.

nnnn

The Series has a built-in IPO and noise filter that

nnnn

improves noise immunity and allows the device to

nnnn

operate even in worst condition.

nnnn

Affordable and Efficient Tools

nnnn

ZiLOG offers a comprehensive yet affordable design

nnnn

tool which ia available with a free license of ANSI

nnnn

C-Compiler, ZDS II-Z8 Encore! XP® IDE, real-time

nnnn

debug port, and a USB smart cable for connecting the

nnnn

PC to development kit.
