PCF8594C-2

512

8-bit CMOS EEPROM with I

C-bus interface

Rev. 05 — 25 October 2004

Product data

1. Description

The PCF8594C-2 is a ﬂoating gate Electrically Erasable Programmable Read Only

Memory (EEPROM) with 4 kbits (512

8-bit) non-volatile storage. By using an

internal redundant storage code, it is fault tolerant to single bit errors. This feature

dramatically increases the reliability compared to conventional EEPROMs. Power

consumption is low due to the full CMOS technology used. The programming voltage

is generated on-chip, using a voltage multiplier.

Data bytes are received and transmitted via the serial I

C-bus. Up to four

PCF8594C-2 devices may be connected to the I

C-bus. Chip select is accomplished

by two address inputs (A1 and A2).

Timing of the E/W cycle is carried out internally, thus no external components are

required. Programming Time Control (PTC), Pin 7, must be connected to either V

or left open-circuit. There is an option of using an external clock for timing the length

of an E/W cycle.

2. Features
