SA24C1024

The SA24C1024 is a 1024Kbit CMOS nonvolatile serial EEPROM organized as 128K x 8 bit memory. This device conforms to Extended IIC 2-wire protocol, which enables accessing of memory in excess of 16 Kbits on an IIC bus. This serial communication protocol uses a Clock signal (SCL) and a Data signal (SDA) to synchronously clock data between a Master (for example, a microcontroller) and a Slave (EEPROM).

The SA24C1024 offers hardware write protection whereby the entire memory array can be write-protected by pulling the WP pin to logic HIGH. The entire memory then becomes unalterable until the WP pin is switched to logic LOW. The device also features programmable write protect with options of full, half or a quadrant of the array.

The LZ version of the SA24C1024 offers very low standby current, which makes it suitable for low power applications. The SA24C1024 is designed to minimize pin count and simplify PC board layout requirements. This device is offered in both SO and DIP packages. A leadless microleadframe package and CSP are under development.

Saifun's EEPROMs are designed and tested for applications requiring high endurance, high reliability and low power consumption.
