A 16-bit Single-Cycle CISC MCU Solution

Overview

Z16F Series Flash Microcontroller. Zilog’s ZNEO Z16F is a powerful 16-bit CISC microcontroller that outper-

forms most RISC microcontrollers in its class. The ZNEO Z16F boasts a unique architecture that provides the

power, punch, and performance of a 32-bit, with the code, current efficiency, and cost of a 16-bit. The ZNEO

Z16F CPU boasts a highly optimized instruction set that achieves higher performance per clock cycle, with

less code space and lower overhead than competing architectures.

This powerful, yet simple core with sixteen 32-bit general-purpose registers supports complex CISC address-

ing modes and a single-cycle instruction set that includes frame pointer support, multi-bit shift, and multi-reg-

ister push/pop, as well as performance enhancing instructions such as Link and Unlink for lowering overhead.

Powerful signed and unsigned math operations include 32x32 multiply and 64/32 divide operations.

A rich array of intelligent peripherals and analog features make this microcontroller suitable for a large number

of applications, including security panels, industrial controls and motor control, including AC Induction and

Brushless DC motors.
