Overview
The M95320-DRDW8TP/K is a 32-Kbit serial EEPROM device manufactured by STMicroelectronics. This device operates up to 105 °C and is compliant with the reliability standards defined by the AEC-Q100 grade 2, making it suitable for automotive and industrial applications. It features a simple serial SPI compatible interface that can run up to 20 MHz. The memory array is based on advanced true EEPROM technology, organized as 128 pages of 32 bytes each, with an embedded Error Correction Code logic to enhance data integrity. An additional Identification Page is available for storing device identification and sensitive application parameters, which can be permanently locked in read-only mode.
