The Microchip Technology 25AA040T-I/SN is a 4 Kbit serial Electrically Erasable PROM (EEPROM) with a 512 x 8-bit organization. It communicates using a Serial Peripheral Interface (SPI) compatible serial bus, requiring clock (SCK), data in (SI), and data out (SO) lines.
This device features a maximum clock frequency of 1 MHz and operates within a voltage range of 1.8V to 5.5V. The operating temperature range is -40°C to 85°C. Key electrical characteristics include a typical read current of 500 μA, a typical write current of 3 mA, and a low standby current of 500 nA. The write cycle time is a maximum of 5 ms.
Designed for reliability, the 25AA040T-I/SN 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. ESD protection is rated at over 4000V.
The 25AA040T-I/SN is available in an 8-pin SOIC package, suitable for surface mounting. Its SPI interface allows for sequential reads and controlled access via a Chip Select (CS) input. The HOLD pin can pause communication, enabling the host to service higher priority interrupts.
