Change Description:
Atmel launched a new low voltage (1.7V- 3.6V) variant of the I2C 2-Kbit EEPROM Industrial
Grade (-40C to +85C) device AT24C32E in 2014. The new, low voltage device has significant
improvements and advantages over the existing wide voltage (1.7V – 5.5V) device AT24C32D
with respect to power consumption, endurance, and noise suppression. With a growing number
of MCUs, SoCs, and ASICs migrating to lower supply voltages as a result of process lithography
reductions, and to reduce power consumption, Atmel developed the AT24C32E to specifically
work with a 1.7V to 3.6V supply.
However Atmel recognizes that some applications might still require a 5V supply voltage, so this
addendum to the PCN is to confirm that Atmel will continue to support and produce the wide
voltage device AT24C32D.
Therefore, customers may continue with the AT24C32D in all applications that use 5V
or 3.3V supply voltage. However, for applications tailored towards low voltage operation (e.g.
1.8V, 3.0V, etc.), Atmel recommends customers migrate to the enhanced performance of the
AT24C32E. (See table below for details of AT24C32E’s low voltage enhancements.)
