EC24C512C-512K Bits Two-Wire Serial EEPROM

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 (65,536×8), 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.
