Features
Note:
Zilog’s eZ80F92 device is a high-speed single-cycle instruction-fetch microcontroller with
a maximum clock speed of 20 MHz. It is the first member of Zilog’s new eZ80Acclaim!
product family, which offers on-chip Flash program memory.
The eZ80F92 device can operate in Z80
24-bit addressing mode (16 MB). The rich peripheral set of the eZ80F92 device makes
it suitable for a variety of applications including industrial control, embedded communica-
tion, and point-of-sale terminals.

1. For simplicity, the term eZ80
Single-cycle instruction fetch, high-performance, pipelined eZ80
eZ80F92 contains 128 KB Flash memory and 8 KB SRAM
eZ80F93 contains 64 KB Flash memory and 4 KB SRAM
Low power features including SLEEP mode, HALT mode, and selective peripheral
power-down control
Two UARTs with independent baud rate generators
SPI with independent clock rate generator
I
IrDA-compliant infrared encoder/decoder
New DMA-like CPU instructions for efficient block data transfer
Glueless external peripheral interface with 4 Chip Selects, individual Wait State
generators, and an external WAIT input pin—supports Z80-, Intel-, and Motorola-
style buses
Fixed-priority vectored interrupts (both internal and external) and interrupt controller
Real-Time Clock with on-chip 32 kHz oscillator, selectable 50/60 Hz input, and
separate V
Six 16-bit Counter/Timers with clock dividers and direct input/output drive
2
C with independent clock rate generator
Additionally, Zilog offers the eZ80F93 device, which features scaled-down mem-
ory options. For clarity, this document refers to both devices collectively as the
eZ80F92 device, unless otherwise specified.
