ST EEPROM products are the standard of reference in the industry, built with sub-micron
technology and offering leading performances. The ranges include serial access EEPROMs with
the 400 kHz, I
2
C low cost, 2-wire bus and densities up to 512 Kbit; fast 1 MHz MICROWIRE bus
types at densities from 256 bit to 16 Kbit; and very fast 5 MHz SPI bus types with densities up to
256 Kbit.
The I
2
C types are suitable for low cost, 2-wire bus applications that do not require fast bus speeds
- up to 400 kHz, they feature high densities with extended addressing above 16 Kbit. The
MICROWIRE types feature a fast 1 MHz bus, but are limited to 16 Kbit density.
For fast applications the SPI bus is preferred, offering 5 MHz operation together with high density
types up to 256 Kbits.
• Wide range from 256 bit to 512 Kbit
• Three bus types, I
2
C, MICROWIRE and SPI
• Standard and low voltage operation
• High ESD protection
• Dual-In-Line, SO, ultra-small TSSOP packages and SBGA (Chip Scale Package)
• Target endurance of over 10 million erase/write cycles, with
over 40 years data retention

EEPROMs EVERYWHERE
The EEPROM is the most flexible non-
volatile memory, featuring Byte level write,
without the need to erase before writing a
new value.
This makes it ideal for parameter storage -
for example for printer setup values,
Carradio and Set Top Box tuning
information, telephone numbers and a host

of other applications. In
fact there are few systems
today which do not need
non-volatile parameter
storage.
But EEPROMs also find
uses for security and
information “tags”.
Storing user ID codes,
access permission keys
and manufacturing
information.
A small EEPROM
mounted on the system
PCB can easily carry manufacturing lot
numbers, software version, giving servicing
traceability at a cost much lower than a
paper trail.
EEPROMs are everywhere.
