eZ80Acclaim!™
Flash Microcontrollers
an IrDA EnDec that facilitates wireless data transfer. In
addition, the eZ80F92 and eZ80F93 devices offer a pin-
compatible footprint with the eZ80L92 and
backwards compatibility to the Z80® and Z180.
Overall, the eZ80Acclaim!™ MCUs are an exceptional
value for customers designing high performance, 8-bit
MCU-based systems.

Product Overview
The eZ80Acclaim!™ family of Flash Microcontrollers
(MCUs) is the latest addition to ZiLOG's microcontroller
line-up offering on-chip Flash memory. With speeds up to
50MHz and an on-chip Ethernet MAC (eZ80F91 only),
designers have the necessary performance to execute
complex applications quickly and efficiently. Combining up
to 256KB of Flash with up to 16KB SRAM, the
eZ80Acclaim!™ Flash MCU devices provide the memory
needed to implement communication protocol stacks and
achieve the flexibility when performing in-system updates
of application firmware.
The eZ80Acclaim!™ Flash MCU can operate in full 24-bit
linear mode addressing 16MB without a Memory
Management Unit. Additionally, support for the Z80-
compatible mode allows Z80®/Z180 customers to execute
legacy code within multiple 64KB memory blocks with
minimum modification. With an external bus supporting
eZ80®, Z80®, Intel®, and Motorola® bus modes,
designers have several options when interfacing to
external devices.
These high performance, 8-bit Flash microcontrollers offer
a rich set of serial communication peripherals including
two UARTs supporting multi-drop mode, I
