Description

The PCF85102C-2 and PCF85103C-2 (further referred to as PCF8510xC-2) are 2 kbits (256 ´ 8-bit) floating gate Electrically Erasable Programmable Read Only Memories (EEPROMs). Power consumption is low due to the full CMOS technology used. The programming voltage is generated on-chip, using a voltage multiplier. The PCF85103C-2 is pin compatible to widely used industrial pinning (pin 7 not connected).

As data bytes of PCF85103C-2 are received and transmitted via the serial I2C-bus, a package using eight pins is sufficient. Up to sixteen PCF8510xC-2 devices may be connected to the I2C-bus. PCF85103C-2 is possible with the introduction of a second device selection code. Chip select is accomplished by three address inputs (A0, A1 and A2) for each PCF8510xC-2 type.
