DS1251YP-100

The DS1251YP-100 belongs to the DS1251YP series. It is a 4096 K NV SRAM,fully static nonvolatile RAM. DS1251YP-100 has some features as follows. (1) real-time clock; (2) 512 k x 8 NV SRAM directly replaces volatile static RAM or EEPROM; (3) embedded lithium energy cell maintains calendar operation and retains RAM data; (4) watch function is transparent to RAM operation; (5) full 10% operating range; (6) lithium energy source is electrically disconnected to retain freshness until power is applied for the first time; (7) DIP module only; (8) PowerCap® module board only.

What comes next is some description concerning absolute maximum ratings of DS1251YP-100. (1): voltage on any pin relative to ground is from -0.3 V to 6.0 V; (2): soldering temperature is 260 for 10 seconds. Then is something about its electrical characters over the operating range VCC is 3.3 V. (1): the maximum input leakage current (IIL) is 1.0 A; (2): the minimum output current (IOH) is -1.0 mA; (3): the minimum output current (IOL) is 2.0 mA; (4): write protection voltage (VPF) is from 2.80 V to 2.97 V.
