Data Sheet Extension 09.98
Introduction
This document describes changes and extensions of the Data Sheet 07.95 of
SLE 4432 / SLE 4442. All information of the Data Sheet 07.95 are also valid for SLE 4440 and
SLE 4441 (e.g. operational information) except the data mentioned in this document.
In detail the following items are added or changed
Memory size SLE 4440
Memory size SLE 4441
Ambient temperature T
A
–35°C…+80°C
ESD protection min. 1500 V, typical 4000 V
Endurance minimum 100000 write/erase cycles / bit
Package: Module M3
Coding information
Especially the transmission protocol (2-wire) and commands are fully compatible for all chip
types.

Memory Overview
The memory is organized in a
Main Memory
of
64 byte for SLE 4440
128 byte for SLE 4441
256 byte for SLE 4432 and SLE 4442
Each of the first 32 bytes of the Main Memory can be irreversibly protected against data change
by writing the corresponding bit in the
Protection Memory
(32 bit). Dependent on the state of the
protection bit the memory is read only (ROM) or may be erased and written again (EEPROM).
Change of the manufacturer code is only possible by the chip manufacturer.
Change of data of the Main Memory and write a bit of the Protection Memory is only possible
after a correct verification of the

ode (
PSC
) for SLE 4440, SLE 4441
and SLE 4442.
