A24C512 MEMORY EEPROM 512k BITS (65536 X 8) TWO-WIRE SERIAL
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.
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
(VCC) has reached an acceptable stable level above
the reset threshold voltage. Once VCC passes 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 VCC drops 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 VCC is within its operating level.
The A24C512 is available in SOP8, TSSOP8 and
DFN8 packages.
