Microchip Technology, Inc. Memory 25LC512-I/S16K

The 25LC512-I/S16K from Quarktwin Technology Ltd. is a 512 Kbit SPI Bus Serial EEPROM designed for applications requiring reliable non-volatile memory storage. It operates within a supply voltage range of 2.5V to 5.5V and supports a maximum clock speed of 20 MHz. The device features byte and page-level write operations with a maximum write time of 5 ms for 128-byte pages, eliminating the need for page or sector erase prior to writing. This EEPROM utilizes low-power CMOS technology, with a maximum write current of 5 mA and a read current of 10 mA at 5.5V. In deep power-down mode, the standby current is as low as 1 ¬µA. The device includes built-in write protection mechanisms, such as a write-protect pin and power-on/off data protection circuitry, enhancing data integrity. The 25LC512-I/S16K is rated for high reliability, with an endurance of 1 million erase/write cycles and a data retention period exceeding 200 years. It is available in multiple package types, including 8-Lead DFN-S, PDIP, SOIC, and SOIJ, and is compliant with RoHS standards. Additionally, it is qualified for automotive applications under AEC-Q100, making it suitable for industrial and automotive environments with temperature ranges from -40¬8C to +125¬8C.
