CPU and Peripheral Overview

The eZ8 CPU, ZiLOG’s latest 8-bit central processing unit, meets the continuing demand

for faster and more code-efficient microcontrollers. The eZ8 CPU executes a superset of

the original Z8® instruction set. The eZ8 CPU features include:

• Direct register-to-register architecture allows each register to function as an accumula-

tor, improving execution time and decreasing the required program memory

• Software stack allows much greater depth in subroutine calls and interrupts than hard-

ware stacks

• Compatible with existing Z8® assembly code

• New instructions improve execution efficiency for code developed using higher-level

programming languages, including C

• Pipelined instruction fetch and execution

• New instructions for improved performance including BIT, BSWAP, BTJ, CPC, LDC,

LDCI, LEA, MULT, and SRL

• New instructions support 12-bit linear addressing of the Register File

• Up to 10 MIPS operation

• C-Compiler friendly

• 2-9 clock cycles per instruction

• For more information regarding the eZ8 CPU, refer to the eZ8 CPU User Manual

(UM0128), available for download at www.zilog.com.

Pulse-Width Modulator for Motor Control Applications

To rotate a 3-phase motor three voltage and current signals must be supplied, each 120°

shifted from each other. To control a 3-phase motor the MCU must provide 6 PWM out-

puts.

The Z8FMC16100 Series Flash MCU features a flexible PWM module with three comple-

mentary pairs or six independent PWM outputs supporting deadband operation and fault

protection trip input. These features provide multiphase control capability for a variety of

motor types and ensure safe operation of the motor by providing immediate shutdown of

the PWM pins during fault condition.

10-Bit Analog-to-Digital Converter

The Z8FMC16100 Series Flash MCU devices feature up to eight channels of 10-bit A/D

conversion.
