MICROCHIP AT24C512C 512 Kbit Serial E2PROM, 64K x 8bit, 8-Pin WSOIC
MICROCHIP 512 Kbit serial E2PROM with I2C interface. 1MHz, 2.5-5.5V, 1M write cycles, 100-year retention. 8-pin WSOIC package.
The MICROCHIP AT24C512C-SSHD-T is a high-performance, low-power 512-Kbit serial EEPROM using the industry-standard I²C (2-wire) interface. Internally organised as 65,536 words of 8 bits each, it offers reliable non-volatile memory for a wide range of data storage applications. This device is optimised for industrial and commercial settings where efficient, low-voltage operation is essential.
A key feature is its robust cascading capability, allowing up to eight devices to share a common two-wire bus, significantly expanding system memory capacity. Enhanced data integrity is provided by built-in Schmitt triggers and filtered inputs for superior noise suppression, ensuring stable operation in electrically noisy environments.
Performance & Reliability
The memory offers exceptional endurance with a minimum of 1,000,000 write cycles and outstanding data retention of 100 years minimum. Write operations are fast and efficient with a self-timed write cycle of 5ms maximum in fast mode. For hardware-level data protection, a dedicated write-protect pin safeguards the entire memory array.
Versatile Memory Management
Flexible data handling is supported through a 128-byte page write mode, which allows partial page writes, along with both random and sequential read modes. The device operates across a broad supply voltage range from 2.5V to 5.5V, making it compatible with various system voltages. It is housed in a compact 8-pin WSOIC (SOIC) package designed for surface-mount assembly and operates reliably across a full industrial temperature range from -40°C to +85°C.
