... Kbit Electrically Erasable PROM. The device is organized as a single block 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. It has been developed for advanced, low- power applications such as personal communications or data acquisition ...

FUNCTIONAL DESCRIPTION The 24XX32A 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 to ...

DEVICE ADDRESSING A control byte is the first byte received following the Start condition from the master device (Figure 5-1). The control byte consists of a four-bit control code. For the 24XX32A, this is set as ‘1010’ binary ...

... However, instead of generating a Stop condition, the master transmits additional bytes 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 five lower 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 Write ...

... Random Read Random read operations allow the master to access any memory location in a random manner. To perform this type of read operation, the word address must first be set. This is accomplished by sending the word address to the 24XX32A as part of a write operation (R/W bit set to ‘ ...
