eZ80F91 Module
This section describes the eZ80F91 Module hardware, its interfaces and
key components, including the CPU, real-time clock, and memory.
Functional Description
The eZ80F91 Module is a compact and high-performance module. It has
been designed for the rapid development and deployment of embedded
systems.
Despite its small footprint, the eZ80F91 Module provides a CPU, Ether-
net interface, SRAM, and a real-time clock. This module is powered by
the eZ80F91 microcontroller, a member of eZ80Acclaim!

eZ80F91 Module Operational Description
The purpose of the eZ80F91 Module as a feature of the eZ80F91 Contest
Kit is to provide a design platform. It enables to make use of eZ80F91
device features such as on-chip EMAC, SRAM, Flash, etc.
Static RAM
The eZ80F91 Module features 128 KB of fast SRAM. Access speed is
typically 12 ns, allowing zero-wait-state operation at 50 MHz. With the
CPU at 50 MHz, SRAM can be accessed with zero wait states in eZ80
mode. CS1_CTL (CS1) can be set to
