... Serial Electrically Erasable PROM with operation (1) 400 kHz down to 1.5V. The device is organized as a single block of 128 x 8-bit memory with a 2-wire serial interface. Low-current design permits operation with maximum standby and active currents of only 1 μA and 400 μA, respectively. The device has a page write capability for bytes of data ...

FUNCTIONAL DESCRIPTION The 24VL014 supports a bidirectional, 2-wire bus and data transmission protocol. A device that sends data onto the bus is defined as transmitter, and a device receiving data as receiver. The bus has to be controlled ...

Page 7

BUS CHARACTERISTICS The following bus protocol has been defined: • Data transfer may be initiated only when the bus is not busy. • During data transfer, the data line must remain stable whenever the clock line is high. Changes ...

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 24VL014 this is set as ‘1010’ binary ...

... But instead of generating a Stop condition, the master transmits additional data bytes to the 24VL014 that are temporarily stored in the on-chip page buffer and will be written into the 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 one ...

Page 10

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 ...

... To provide sequential reads, the 24VL014 contains an internal Address Pointer which is incremented by one at the completion of each operation. This Address Pointer allows the entire memory contents to be serially read during one operation. The internal Address Pointer will automatically roll over from address 7F to address 00h ...
