MAXIM DS2045L DS2045L 3.3V Single-Piece 1Mb Nonvolatile SRAM handbook

Update: 29 September, 2023

The DS2045L is a 1Mb reflowable nonvolatile (NV) SRAM, which consists of a static RAM (SRAM), an NV controller, and an internal rechargeable manganese lithium (ML) battery. These components are encased in a surface-mount module with a 256-ball BGA footprint. Whenever VCC is applied to the module, it recharges the ML battery, powers the SRAM from the external power source, and allows the contents of the SRAM to be modified. When VCC is powered down or out-of-tolerance, the controller write-protects the SRAM’s contents and powers the SRAM from the battery. The DS2045L also contains a power-supply monitor output, RST, which can be used as a CPU supervisor for a microprocessor.
