EZ80F91AZA50EG Overview

The eZ80F91AZA ASSP device, a member offamily of eZ80AcclaimPlus! Flash microcontrollers, is the 144-pin LQFP version ofhigh-speed eZ80F91 microprocessor. Like the rest of the eZ80Acclaim Plus! family, the eZ80F91AZA features a maximum clock speed of 50 MHz and single-cycle instruction fetch. It operates in Z80-compatible addressing mode (64 KB) or full 24-bit addressing mode (16 MB).The rich peripheral set of the eZ80F91AZA makes it suitable for a variety of applications, including industrial control, embedded communication, and point-of-sale terminals.Build your embedded application with the eZ80F91 Modular Development Kit (eZ80F910200KITG).

The eZ80F91AZA ASSP is RoHS-compliant.
