Description

The Philips PCB2421 is a 128 ´ 8-bit dual mode serial Electrically Erasable PROM (EEPROM). PCB2421 is designed for use in applications requiring storage and serial transmission of configuration and control information. Two modes of operation have been implemented: transmit-only mode (DDC1 mode) and bidirectional mode (DDC2B, or I2C-bus mode).

Upon power-up, PCB2421 will be in the transmit-only mode, sending a serial bitstream of the entire memory array contents, clocked by the VCLK pin. A valid HIGH-to-LOW transition on the SCL pin will cause the device to enter the bidirectional mode, with byte selectable read/write capability of the memory array. The PCB2421 is available in a standard 8-pin dual in-line and 8-pin small outline package operating in a commercial temperature range.
