BR24C01A 1Kbit Serial I²C-bus EEPROM memory IC DIP-8
The BR24C01A from Rohm is a 2-wire serial EEPROM designed for low-power, non-volatile data storage in embedded systems. Utilizing CMOS technology, it provides 1Kbit (128 words x 8 bits) of memory accessible via an I²C bus interface, with automatic address incrementing and erase-before-write operations. The device supports up to 8 units on a single bus through slave address pins and includes noise filters on SCL and SDA for robust communication. It operates over a wide voltage range with minimal current draw, making it suitable for battery-powered applications. Write protection at low Vcc ensures data integrity, while the DIP-8 package facilitates easy through-hole mounting in prototyping and production.
Features:
- 1Kbit memory organized as 128 words x 8 bits.
- I²C bus compatible two-wire serial interface.
- Low power operation with 0.2mA typical active current at 5V.
- Standby current of 1.0µA typical at 5V.
- Automatic erase-before-write and page write buffer up to 4 bytes.
