General Description
The eZ80F91 MCU is industry’s first MCU
featuring a high-performance 8-bit microcontroller
with an integrated 10/100 BaseT EMAC. It is a
power-efficient, optimized pipeline architecture
microcontroller with a maximum operating speed
of 50 MHz. Offering on-chip Flash Memory,
SRAM, Ethernet MAC, and rich peripherals, the
eZ80F91 is well-suited for industrial, communica-
tion, automation, security, and embedded Internet
applications.

In addition, 16 KB of high-speed, relocatable
SRAM is available and 8 KB is for general-
purpose use. Another 8 KB is used by the EMAC
for Ethernet operation, but is also user-accessible
when Ethernet functionality is not required.
General-Purpose Input/Output
There are 32 bits of GPIO. All GPIO pins are
individually programmable and support the
following I/O modes: input, output, open drain,
open source, level-triggered interrupts (High or
Low), edge-triggered interrupts (High or Low),
dual edge-triggered interrupts, and alternate
function. Eight of the output pins can drive 10 mA
each (Port A), while 16 other pins feature
Schmitt-trigger input buffers (Port B and Port C).
10/100 BaseT Ethernet MAC
The eZ80F91 MCU features an integrated IEEE
8 0 2 . 3 E t h e r n e t c o n t r o l l e r w i t h 8 K B o f
dynamically-configurable Tx/Rx frame buffer. It
supports speed of 10 Mbps and 100 Mbps, full
duplex operation, and an industry-standard Media
Independent Interface (MII) for simple connection
to an external Physical Layer interface (PHY)
device. The eZ80F91 delivers high performance
and overall cost effectiveness as an embedded
network microcontroller.
High performance is achieved by optimizing the
internal bus design of the eZ80
memories, dedicated Ethernet Tx/Rx DMAs, and
Tx/Rx FIFOs. This bus design provides the highest
data throughput over the Ethernet interface, yet
requires minimum eZ80
minimizes system loading.
