eZ80Acclaim!™Flash Microcontrollers
The new 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!™devices provide the memory needed to imple-
ment 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 support-
ing 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 sup-
porting multi-drop mode, I2C, SPI, and 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.
