EC24C512C数据手册E-CMOS中文资料规格书

描述 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.
