The 25AA256/S16K is a 256 Kbit Serial Electrically Erasable Programmable Read-Only Memory (EEPROM) from Quarktwin Technology Ltd., designed for use with a Serial Peripheral Interface (SPI). It operates within a supply voltage range of 1.8V to 5.5V and supports a maximum clock frequency of 10 MHz. The memory is organized as 32,768 x 8 bits and features a 64-byte page size for efficient data handling. This device incorporates low-power CMOS technology, with a maximum write current of 5 mA and a read current of 6 mA at 5.5V. It has a standby current of only 1 µA, making it suitable for battery-powered applications. The 25AA256/S16K supports self-timed erase and write cycles, with a maximum time of 5 ms, and includes block write protection options. The EEPROM is rated for high reliability, with an endurance of 1,000,000 erase/write cycles and data retention exceeding 200 years. It also features ESD protection greater than 4000V and is compliant with RoHS standards. The device is available in various package types, including PDIP, SOIC, DFN, and TSSOP, and is qualified for automotive applications under AEC-Q100.
