Оперативная память DS1245YP-70+

NVRAM , SRAM, 1 Мбит, 128К x 8бит, 70 нс, PWRCP

The DS1245YP-70+ is a 1024K non-volatile SRAM in 34 pin PWRCP package. This 1,048,576bit fully static non-volatile SRAM is organized as 131,072 words by 8 bits. It has self contained lithium energy source and control circuitry which constantly monitors VCC for an out of tolerance condition. When such a condition occurs, the lithium energy source will be automatically switched on and write protection is unconditionally enabled to prevent data corruption. Lithium energy source is electrically disconnected to retain freshness until power is applied for the first time. DS1245 device in PowerCap module package is directly surface mountable and is normally paired with DS9034PC PowerCap to form a complete non-volatile SRAM module. There is no limit on the number of write cycles that can be executed and additional support circuitry is not required for microprocessor interfacing.
