I2C Bidirectional Data Eeprom Memory Chip 256 Kbits BL24C256A-PARC

Product Specification

Compatible With All I2C Bidirectional Data 256 Kbits Of EEPROM Transfer  Protocol Erasable Programmable Read-Only Memory BL24C256A-PARC

Features 
 Compatible with all I2C bidirectional data 
transfer  protocol 
 Memory array: – 256 Kbits (32 Kbytes) of EEPROM – Page size: 64 bytes – Additional Write lockable page 
 Single supply voltage and high speed: – 1 MHz  
 Random and sequential Read modes 
 Write: – Byte Write within 3 ms   
Description 
 The BL24C256A provides 262144 bits of serial 
electrically erasable and programmable read
only memory (EEPROM), organized as 32768 
words of 8 bits each. 
 The device is optimized for use in many 
industrial and commercial applications where – Page Write within 3 ms  – Partial Page Writes Allowed 
 Write Protect Pin for Hardware Data Protection 
 Schmitt Trigger, Filtered Inputs for Noise 
Suppression 
 High-reliability – Endurance: 1 Million Write Cycles – Data Retention: 100 Years 
 Enhanced ESD/Latch-up protection – HBM 8000V 
 8-lead PDIP/SOP/TSSOP/UDFN packages 
low-power and low-voltage operation are 
essential. 
 The BL24C256A offers an additional page, 
named the Identification Page (64 bytes). The 
Identification Page can be used to store 
sensitive application parameters which can be 
(later) permanently locked in Read-only mode.
