Overview

nnnn

Zilog's Z8FMC16100 Series Flash microcontrol-

nnnn

TM

nnnn

lers, a part of the Z8 Encore! MC family of motor

nnnn

control devices, are based on Zilog's advanced

nnnn

eZ8™ 8-bit CPU core. Optimized for motor con-

nnnn

trol applications, these devices support the control

nnnn

of Single and Multiphase variable-speed motors.

nnnn

Target applications are large appliances, small

nnnn

appliances, HVAC, automotive, power tools, and

nnnn

personal care devices.

nnnn

Z8FMC16100 Series Flash MCUs feature a

nnnn

flexible pulse width modulator (PWM) module

nnnn

with three complementary pairs or six independent

nnnn

PWM outputs supporting dead-band operation and

nnnn

fault protection trip input. These features provide

nnnn

multiphase control capability for a variety of motor

nnnn

types and ensure safe operation of the motor by

nnnn

providing Pulse-by-Pulse or latched fast shutdown

nnnn

of the PWM pins during fault condition.

nnnn

Z8FMC16100 Series MCU features up to eight

nnnn

single-ended channels of 10-bit analog-to-digital

nnnn

conversion, with a sample and hold circuit. It also

nnnn

features one operational amplifier for current

nnnn

sampling and one comparator for over-current

nnnn

limiting or shutdown.

nnnn

A high-speed analog-to-digital converter (ADC)

nnnn

enables voltage, current, and back-EMF sensing,

nnnn

while dual-edge interrupts and a 16-bit timer

nnnn

provide a Hall-effect sensor interface.

nnnn

A full-duplex 9-bit UART provides serial,

nnnn

asynchronous communication and supports the

nnnn

local interconnect network (LIN) serial

nnnn

communications protocol. The LIN bus is a

nnnn

cost-efficient Single Master, Multiple Slave

nnnn

organization that supports speed up to 20 kbps.

nnnn

Included in its rich-set of peripherals are other

nnnn

features such as: one additional 16-bit timer with

nnnn

Capture/Compare/PWM capability, SPI or I C

nnnn

Master/Slave for serial communication, and an

nnnn

internal precision oscillator (IPO).

nnnn

The single-pin debugger and programming

nnnn

interface simplifies code development and allows

nnnn

easy in-circuit programming.
