DESCRIPTION
FEATURES
The A24C1024 are EEPROM devices that use the
industrial standard 2-wire interface for communications.
Two-Wire Serial Interface, I2CTM Compatible
– Bi-directional data transfer protocol
Wide-voltage Operation – VCC = 1.7V to 5.5V
Speed: 400 KHz (1.7V) and 1 MHz (2.5V~5.5V)
Standby current (max.): 1μA, 1.7V
Read operating current (max.): 1mA, 1.7V
Write operating current (max.): 3mA, 1.7V
Hardware Data Protection
The A24C1024 contains
a
memory array of
1024K-bits(131.072x8), which is organized in
256-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 A24C1024 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).
– Write Protect Pin
Sequential & Random Read Features
Memory organization: 131,072 x 8 bits
Page Size: 256 bytes
Page write mode
Utilizing such bus protocol, a Master device, such as
a microcontroller, can usually control one or more
Slave devices, alike this A24C1024. 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 A24C1024 also has a Write
Protect pin (WP) to allow blocking any write
operations over specified memory area.
– Up to 256 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
Industrial temperature grades
Available in SOP8 and TSSOP8 Packages
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.
