The DS2030 is a 256kb 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. Two versions of the DS2030 are available, which provide either a 5% or 10% power-monitoring trip point. The DS2030 also contains a power-supply monitor output, RST, which can be used as a CPU supervisor for a microprocessor.
The DS2030 is a single-piece, reflowable nonvolatile (NV) SRAM module available in two versions: the DS2030AB with a 5% supply tolerance and the DS2030Y with a 10% supply tolerance. The device consists of static RAM, an NV controller, and an internal rechargeable manganese lithium battery encased in a 27mm² PBGA package.
