The Microchip 4Kbit EEPROM (part number 30H4681) operates within a temperature range of -40¬8C to +125¬8C, making it suitable for both industrial and automotive applications. It features a memory organization of 512 x 8-bit or 256 x 16-bit, depending on the specific device variant. The EEPROM utilizes a serial Microwire interface with a maximum clock frequency of 3 MHz, ensuring efficient data communication. This device supports low-power CMOS technology and includes features such as self-timed erase/write cycles, automatic erase before write, and power-on/off data protection circuitry. It is rated for 1,000,000 erase/write cycles and offers data retention exceeding 200 years. The product is available in various package types, including 8-lead PDIP and SOIC, and is compliant with RoHS standards.
