... Kbit Electrically Erasable PROM. The device is organized as two blocks of 256 x 8-bit (1) I memory with a 2-wire serial interface. Low-voltage I, E design permits operation down to 1.7V, with standby and active currents of only 1 μA and 1 mA, respectively. The 24XX04 also has a page write capability for bytes of data ...

... SS (read/write the entire memory 000-1FF). If tied write operations are inhibited. The entire CC memory will be write-protected. Read operations are not affected. The Chip Scale package does not support the write- protect feature. 2.4 A0, A1, A2 The A0, A1 and A2 pins are not used by the 24XX04. ...

FUNCTIONAL DESCRIPTION The 24XX04 supports a bidirectional, 2-wire bus and data transmission protocol. A device that sends data onto the bus is defined as transmitter, while a device receiving data is defined as a receiver. The bus has ...

... The next two bits of the control byte are “don’t cares” for the 24XX04. The last bit, B0, is used by the master device to select which of the two 256-word blocks of memory are to be accessed. This bit is, in effect, the Most Significant bit of the word address. The last bit of the control byte defines the operation to be performed. When set to ‘ ...

... But instead of generating a Stop condi- tion the master transmits data bytes to the 24XX04, which are temporarily stored in the on-chip page buffer and will be written into memory once the master has transmitted a Stop condition. Upon receipt of each word, the four lower-order Address Pointer bits are internally incremented by ‘ ...

ACKNOWLEDGE POLLING Since the device will not acknowledge during a write cycle, this can be used to determine when the cycle is complete (this feature can be used to maximize bus throughput). Once the Stop condition for a ...
