Standard Serial EEPROM

Standard Serial EEPROM are competitive products designed for flexible and reliable management of parameters in Smart Things, Smart Homes/Cities as well as Smart Industry with extended temperature ranges. Products feature up to 4 million write/erase cycles per byte, over 100 million cycles per device and 200 years data retention.

The Industrial 85 °C line offers products with a focus on low voltage, low pin-count and the smallest form factor to fit mobile, consumer and computer applications. Packages such as DFN8, DFN5, WLCSP 8/4 balls and bare die allow to fit in the tiniest modules. Low-power operation also makes them ideal for battery-operated wearable modules. 

I2C – M24xxx 1 Kbit to 2 Mbits 1.6 to 5.5 V Up to 1 MHz I2C EEPROM
SPI – M95xxx 1 Kbit to 4 Mbits 1.7 to 5.5 V Up to 20 MHz SPI EEPROM
Microwire – M93xxx 1 to 16 Kbits 2.5 to 5.5 V Up to 2 MHz Microwire EEPROM

Industrial-Plus 105 °C products are proposed in SO8N and TSSOP8 packages to design robust solutions for Smart Cities such as networking, power and lighting in outdoor applications. Products offer improved traceability thanks to a lockable page and extended operating temperature ranges. 

I2C – M24xxx 2 to 512 Kbits 1.7 to 5.5 V Lockable page I2C EEPROM
SPI – M95xxx 4 to 512 Kbits 1.7 to 5.5 V Lockable page SPI EEPROM

Benefits of I2C EEPROM in DFN5 package

The 5-pin DFN is a standard JEDEC package with an extremely compact outline (1.4 x 1.7 mm) making it a versatile alternative between the standard 8-pin DFN (2 x 3 mm) package and the more advanced chip scale package solution. Its plastic encapsulated package using conventional copper lead frame technology makes it very robust for handling and manufacturing. Ensuring a reduced footprint and lower weight while maintaining an easy manufacturing process, the  DFN5 I2C EEPROM is ideal for boot, setup and datalog functions in communication and sensor modules used in portable applications. ST's  DFN5 I2C EEPROM portfolio is complete with devices  from 2 up to 128 Kbits.

4-ball WLCSP EEPROM designed for tiny Camera modules.

Camera modules for mobile devices follow a path of quick miniaturization while display resolution increases and requires a higher set of parameters to operate efficiently.

The 4-ball WLCSP I2C EEPROM family provides a minimal pin count, footprint and thickness, fitting the most stringent hardware design requirements. In addition, thanks to internally-wired device select code options, the EEPROM for rear and front cameras can share the same I2C bus, providing further module design optimization.

The factory-programmed settings can also be protected when selecting products with the software write-protect instruction.

Manufacturing robustness aspects are also covered with an optional back-side coating.
