512k BITS (65536 X 8) TWO-WIRE SERIAL

DESCRIPTION

FEATURES

The A24C512 are EEPROM devices that use the

industrial standard 2-wire interface for

communications. The A24C512 contains a memory

array of 512k-bits (65,536x8), which is organized in

128-byte per page.

The EEPROM can operate in a wide voltage range

from 1.7V to 5.5V which fits most application. This

product can provide a low-power 2-wire EEPROM

solution.

The A24C512 is compatible with the industrial

standard 2-wire bus protocol. If in case the bus is not

responded, a new sent Op-code command will reset

the bus and the device will respond correctly. The

simple bus consists of the Serial Clock wire (SCL)

and the Serial Data wire (SDA).

Utilizing such bus protocol, a Master device, such as

a microcontroller, can usually control one or more

Slave devices, alike this A24C512.The bit stream

over the SDA line includes a series of bytes, which

identifies a particular Slave device, an instruction, an

address within that Slave device, and a series of

data, if appropriate. The A24C512 also has a Write

Protect pin (WP) to allow blocking any write

operations over specified memory area.

Two-Wire Serial Interface, I²C^TMCompatible

– Bi-directional data transfer protocol

Wide-voltage Operation – V_CC= 1.7V to 5.5V

Speed: 400 kHz (1.7V) and 1 MHz (2.5V~5.5V)

Standby current (max.): 1uA, 1.7V

Operating current (max.): 2mA, 1.7V

Hardware Data Protection – Write Protect Pin

Sequential & Random Read Features

Memory organization: 65,536 x 8 bits

Page Size: 128 bytes



Page write mode – Up to 128 bytes per page write

Self timed write cycle with auto clear: 5ms (max.)

Filtered inputs for noise suppression

High-reliability

– Endurance: 1 million cycles

– Data retention: 100 years

Under no circumstance, the device will be hung up.

In order to refrain the state machine entering into a

wrong state during power-up sequence or a power

toggle off-on condition, a power on reset circuit is

embedded. During power-up, the device does not

respond to any instructions until the supply voltage

(V_CC) has reached an acceptable stable level above

the reset threshold voltage. Once V_CCpasses the

power on reset threshold, the device is reset and

enters into the Standby mode. This would also avoid

any inadvertent Write operations during power-up

stage.

During power-down process, the device will enter

into standby mode, once V_CCdrops below the power

on reset threshold voltage. In addition, the device will

be in standby mode after receiving the Stop

command, provided that no internal write operation

is in progress. Nevertheless, it is illegal to send a

command unless the V_CCis within its operating level.
