EC24C02A/04A/08A/16A-2K~16K-bit 2-WIRE Serial EEPR

General description

The EC24C02A/04A/08A/16A provides 2048/4096 /8192/16384 bits of serial electrically erasable and programmable read-only memory (EEPROM) organized as 256/512/1024/2048 words of 8 bits each. The device is optimized for use in many industrial and commercial applications where low-power and low-voltage operation are essential. The EC24C02A/04A/08A/16A is available in space saving PDIP-8,SOP-8, TSSOP-8,MSOP8, DFN-8 and SOT23-5 packages and is accessed via a two-wire serial interface.
