Description
The M95320 devices are Electrically Erasable PROgrammable Memories (EEPROMs) organized as 4096 x 8 bits, accessed through the SPI bus.
The M95320 devices can operate with a supply range from 1.8 V up to 5.5 V, and are guaranteed over the -40 °C/+85 °C temperature range.
The M95320-D offers an additional page, named the Identification Page (32 bytes). The Identification Page can be used to store sensitive application parameters which can be (later) permanently locked in Read-only mode.
