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

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.
