EC24C512C
512K bits Two-wire Serial EEPROM
General Description
The EC24C512C are EEPROM devices that use
the industrial standard 2-wire interface for
communications.
The EC24C512C 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 device
is offered in Lead-free, RoHS, halogen free or
Green. The available package types are 8-pin
SOP, TSSOP, DFN.
The EC24C512C 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
EC24C512C. 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
EC24C512C also has a Write Protect pin (WP) to allow
blocking any write operations over specified memory area.
The EC24C512C also offers an additional page, named the
Identification Page (128 bytes) which can be written and
(later) permanently locked in Read-only mode. This
Identification Page offers flexibility in the application board
production line, as the Identification Page can be used to
store unique identification parameters and/or parameters
specific to the production line.
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.
