DS1312S/T&R

DS1312ST&R Description Analog Devices DS1312ST&R is a non-volatile controller that solves the application problem of converting CMOS RAM into non-volatile memory.
The DS1312ST&R has a variety of features, including support for battery backup and detection of remaining lithium battery capacity. DS1312 is suitable for those applications where the supply voltage is between 4.75V and 5.5V. DS1312ST&R
