Microchip Technology, Inc. 16Kb I2C Serial EEPROM with Software Write Protection in 4-Ball WLCSP 24CW16

The 24CW16X provides 16 Kbits of Serial EEPROM utilizing an I2C (2-wire) serial interface. It is organized as 2048 bytes of 8 bits each (2 Kbytes). The 24CW Series is optimized for use in consumer and industrial applica- tions, where reliable and dependable nonvolatile mem- ory storage is essential. The 24CW Series allows up to eight devices to share a common I2C (2-wire) bus and is capable of operation across a broad voltage range (1.6V to 5.5V). The 24CW Series contains a pair of programmable Configuration registers which allow certain device behaviors to be modified. These registers are the Write Protection Register and the Hardware Address Register. Additional Features Internally organized as one 2048 x 8 bit block Byte or page writes up to 32 bytes Self-timed write cycle (5ms maximum) High-Speed I2C Interface: Industry standard: 1MHz, 400kHz and 100 kHz Output slope control to eliminate ground bounce Schmitt trigger inputs for noise suppression Programmable Hardware Slave Address Bits Configurable via the Hardware Address Register (HAR) Versatile Data Protection Options Software write protection via the Write Protection Register (WPR) Operating Voltage Range of 1.6V to 5.5V Low-Power CMOS Technology Write current: 1.0 mA maximum at 5.5V Read current: 1.0 mA maximum at 5.5V, 1 MHz Standby Current: 1 μA at 5.5V High Reliability More than one million erase/write cycles Data retention:>200years ESD protection:>4000V RoHS Compliant
