128 Kbyte Flash Module (S12XFTX128K1V1)
29.1
This document describes the FTX128K1 module that includes a 128 Kbyte Flash (nonvolatile) memory.
The Flash 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 Flash memory is ideal for program and 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 Flash module supports both block erase and
sector erase. An erased bit reads 1 and a programmed bit reads 0. The high voltage required to program
and erase the Flash memory is generated internally. It is not possible to read from a Flash block while it is
being erased or programmed.
29.1.1
Command Write Sequence — A three-step MCU instruction sequence to execute built-in algorithms
(including program and erase) on the Flash memory.
Multiple-Input Signature Register (MISR) — A Multiple-Input Signature Register is an output
response analyzer implemented using a linear feedback shift-register (LFSR). A 16-bit MISR is used to
compress data and generate a signature that is particular to the data read from a Flash block.

Introduction
Glossary
Features
A Flash word must be in the erased state before being programmed.
Cumulative programming of bits within a Flash word is not allowed.
