The Microchip Technology 25C040X-I/ST is a 4 Kbit serial Electrically Erasable PROM (EEPROM) with a 512 x 8-bit organization. It utilizes a Serial Peripheral Interface (SPI) compatible serial bus for communication, requiring SCK, SI, and SO lines, controlled by a Chip Select (CS) input.
This device features a maximum clock frequency of 3 MHz and operates within a voltage range of 4.5V to 5.5V. The operating temperature range is -40°C to 85°C. Key electrical characteristics include a typical write current of 3 mA, a typical read current of 500 μA, and a standby current of 500 nA.
Designed for reliability, the 25C040X-I/ST offers an endurance of 1M cycles and data retention exceeding 200 years. It includes built-in write protection features such as power on/off data protection circuitry, a write enable latch, and a write-protect pin. The memory supports sequential reads and block write protection.
The EEPROM is supplied in an 8-TSSOP package suitable for surface mounting. Its write cycle time is a maximum of 5 ms, and it features self-timed erase and write cycles.
