24VL024/24VL025

Description:

The Microchip Technology Inc. 24VL024/24VL025 is a

2 Kbit

operation down to 1.5V. The device is organized as a

single block of 256 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 24VL024/

24VL025 devices on the same bus for up to 16 Kbits of

contiguous

available in the standard 8-pin PDIP, 8-pin SOIC (150

mil), TSSOP, 2x3 TDFN and MSOP packages. The

24VL025 is also available in the 6-lead, SOT-23

package.

FUNCTIONAL DESCRIPTION The 24VL024/24VL025 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 ...

Page 8

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 24VL024/24VL025 this is set as ‘1010’ binary ...

Page 9

... Stop condition, the master transmits additional data bytes to the 24VL024/24VL025 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 ...

Page 11

... 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 done by sending the word address to the 24VL024/24VL025 as part of a write operation. ...
