Product Introduction

Overview

The CAT28F001G-12TT is a high-speed 128K x 8 bit electrically erasable and reprogrammable Flash memory produced by onsemi. This device is ideally suited for applications requiring in-system or after-sale code updates. It features a blocked architecture with one 8 KB Boot Block, two 4 KB Parameter Blocks, and one 112 KB Main Block. The Boot Block section can be located at the top or bottom of the memory map and includes a reprogramming write lockout feature to ensure data integrity. The CAT28F001G-12TT is designed with on-chip address latches, data latches, programming and erase algorithms, and is manufactured using advanced CMOS floating gate technology.
