The BL24C256A-NTRC with UDFN-8L-EP(2x3) EEPROM ROHS is a non-volatile memory chip manufactured by Belling. It contains 256 Kbits of electrical erasable programmable ROM (EEPROM) memory, with a UDFN-8L-EP(2x3) surface-mount package type. The chip measures just 2.1x2.4x0.45 mm, and is compliant with RoHS specification. The chip can be operated at temperatures between -40°C and +85°C, allowing it to be used in a range of applications subject to extreme environments. The EEPROM offers 256K bits organized as 32K-byte with byte-write and page-write capability, in addition to a self-timed write cycle. The device is also capable of executing 1 million erase/write cycles, and 100 years of data retention.
