Features
Note:
The 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-compatible addressing mode (64 KB) or full 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 communication, and point-of-sale ter-
minals.
