DESCRIPTION

The DS3832C-311 is a 1,048,576 x 32 advanced NV SRAM module with a 168-bump BGA pinout. The

highly integrated DS3832C-311 contains a 64-byte RTC, four 8Mb SRAMs, and control circuitry that

constantly monitors V_CCfor an out-of-tolerance condition. When such a condition occurs, the DS3832C-

311 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 DS3832C-311 has

dedicated circuitry for monitoring the status of V_CCand the status of an attached DS3802 battery cap.
