DESCRIPTION

The DS3816C-512 is a 524,288 x 32-advanced nonvolatile (NV) SRAM module with a 168-bump ball

grid array (BGA) pinout. The highly integrated DS3816C-512 contains a 64-byte real time clock, four

8Mb SRAMs and control circuitry which constantly monitors V_CCfor an out-of-tolerance condition.

When such a condition occurs, the DS3816C-512 makes use of an attached DS3802 Battery Cap to

maintain clock information and preserve stored data while protecting that data by disallowing all memory

accesses. Additionally, the DS3816C-512 has dedicated circuitry for monitoring the status of V_CCand the

status of an attached DS3802 Battery Cap.
