The Microchip Technology PCD8582-I/P is a 2Kbit serial EEPROM organized as 256 x 8 bits, accessed via an I²C interface at a 100 kHz clock frequency.
The DIP footprint keeps rework straightforward — no hot-air station needed, and the part can be swapped in a production rework loop with a simple soldering iron.
Write cycle time and memory endurance
The word/page write cycle time is 100 ms — budget this into the firmware write routine; a full 256-byte page write takes 100 ms, so a 2 Kbit (256-byte) device can be rewritten in about 25.6 seconds if writing byte-by-byte.
