Microchip Technology, Inc. Memory 25LC080/P

The 25LC080/P is an 8 Kbit Serial Electrically Erasable PROM (EEPROM) from Quarktwin Technology Ltd., designed for use with a Serial Peripheral Interface (SPI) bus. It operates within a voltage range of 2.5V to 5.5V and supports a maximum clock frequency of 2 MHz. The device features low-power CMOS technology, with a maximum write current of 3 mA, a typical read current of 500 µA, and a standby current of 500 nA. This EEPROM has a memory organization of 1024 x 8 bits and supports 16-byte page writes, with a maximum write cycle time of 5 ms. It includes built-in write protection mechanisms, such as power-on/off data protection circuitry and a write-protect pin. The device is rated for high reliability, with an endurance of 1 million cycles and data retention exceeding 200 years. It is available in both 8-pin PDIP and SOIC packages and operates over an industrial temperature range of -40°C to +85°C. However, it is noted that this part is not recommended for new designs, and users are advised to consider the 25AA080A/B or 25LC080A/B as alternatives.
