Description

The Microchip Technology Inc. 24LCS61 / 24LCS62 is a 1K/2K bit Serial EEPROM developed for applications that require many devices on the same bus but do not have the I/O pins required to address each one individually.

These devices contain an 8 bit address register that is set upon power-up and allows the connection of up to 255 devices on the same bus. When the process of assigning ID values to each device is in progress, the device will automatically handle bus arbitration if more than one device is operating on the bus. In addition, an external open drain output pin is available that can be used to enable other circuitry associated with each individual system. Low current design permits operation with typical standby and active currents of only 10µA and 1 mA respectively. The device has a page write capability for up to 16 bytes of data.

Features : 

• Software addressability allows up to 255 devices on the same bus

• 2-wire serial interface bus, I2C compatible

• Automatic bus arbitration

• Wakes up to control code 0110

• General purpose output pin can be used to enable other circuitry

• 100 kHz and 400 kHz compatibility
