Description:
The Microchip Technology Inc. 24VL014H is a 1 Kbit
Serial Electrically Erasable PROM with operation
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
up to 16 bytes of data. Functional address lines allow
the connection of up to eight 24VL014H devices on the
same bus for up to 8 Kbits of contiguous EEPROM
memory. The device is available in the standard 8-pin
PDIP, 8-pin SOIC (150 mil), TSSOP, 2x3 TDFN and
MSOP packages.

... The SCL input is used to synchronize the data transfer to and from the device. 2.3 A0, A1, A2 The A0, A1 and A2 inputs are used by the 24VL014H for multiple device operations. The levels on these inputs are compared with the corresponding bits in the slave address. The chip is selected if the compare is true ...

... The bus has to be controlled by a master device that generates the Serial Clock (SCL), controls the bus access and generates the Start and Stop conditions, while the 24VL014H works as slave. Both master and slave can operate as transmitter or receiver, but the master device determines which mode is activated ...

... Start condition from the master device (Figure 5-1). The control byte consists of a four-bit control code; for the 24VL014H this is set as ‘1010’ binary for read and write operations. The next three bits of the control byte are the Chip Select bits (A2, A1, A0). The Chip Select ...

... Page Write The write-control byte, word address and the first data byte are transmitted to the 24VL014H in the same way byte write. But instead of generating a Stop condition, the master transmits additional data bytes to the 24VL014H that are temporarily stored in ...

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 Write command has been issued from the master, the device initiates the internally-timed write cycle and ACK polling can be initiated immediately ...

Page 11

... Sequential Read Sequential reads are initiated in the same way as a random read except that after the 24VL014H transmits the first data byte, the master issues an acknowledge as opposed to a Stop condition in a random read. This directs the 24VL014H to transmit the next sequentially addressed 8-bit word (Figure 8-3) ...
