The PCF8582A is a 2 Kbits 5 Volt electrically erasable programmable read only memory (EEPROM) organized as 256 by 8-bits. It is designed in a floating gate CMOS technology. As data bytes are received and transmitted via the serial 12C·bus, an eight pin DIL package is sufficient. Up to eight PCF8582A devices may be connected to the 12C·bus. Chip select is accomplished by three address inputs. Timing of the Erase/Write cycle can be done in two different ways; either by connecting an external clock to the "Programming Timing Control", pin (7 or 13), or by using an internal oscillator. If the latter is used an RC time constant must be connected to pin 7 or 13.
