Block Guide — S12EETX4KV0 V00.04

Section 1 Introduction

1.1 Overview

This document describes the EETX4K module which includes a 4K byte EEPROM (Non-Volatile) memory. The EEPROM memory may be read as either bytes, aligned words or misaligned words. Read access time is one bus cycle for bytes and aligned words, and two bus cycles for misaligned words.

The EEPROM memory is ideal for data storage for single-supply applications allowing for field reprogramming without requiring external voltage sources for program or erase. Program and erase functions are controlled by a command driven interface. The EEPROM module supports both block erase (all memory bytes) and sector erase (4 memory bytes). An erased bit reads ‘1’ and a programmed bit reads ‘0’. The high voltage required to program and erase the EEPROM memory is generated internally. It is not possible to read from the EEPROM block while it is being erased or programmed.

NOTE: An EEPROM word (2 bytes) must be erased before being programmed. Cumulative programming of bits within a word is not allowed.
