Microchip Technology, Inc. Memory AT24C256C-MAPD-E

The AT24C256C-MAPD-E is a 256-Kbit (32,768 x 8) I¬=C-compatible EEPROM memory device designed for automotive applications. It operates within a voltage range of 1.7V to 5.5V, making it suitable for low-voltage and medium-voltage applications. The device is qualified according to AEC-Q100 standards, ensuring reliability in automotive environments with an extended temperature range of -40¬8C to +85¬8C. This memory chip features a bidirectional data transfer protocol and supports both standard (100 kHz) and fast (400 kHz) I¬=C modes. It includes a write-protect pin for hardware data protection and offers a low active current of 3 mA maximum, with a standby current of just 6 OºA. The AT24C256C-MAPD-E supports a 64-byte page write mode, allowing for partial page writes, and has a self-timed write cycle time of up to 5 ms. With an endurance of 1,000,000 write cycles and a data retention period of 100 years, this EEPROM is designed for high reliability and longevity. The device is available in multiple package options, including 8-Lead SOIC, 8-Lead TSSOP, and 8-Pad UDFN.
