Z16F Series Flash Microcontroller
A 16-bit Single-Cycle CISC MCU Solution
Overview
From the company that brought you the revolutionary Z80
®
comes the future of 16-bit processing - the ZNEO
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.
