DS1386P-8K-120

The DS1386P-8K-120 is a nonvolatile static RAM with a full-function Real Time Clock (RTC), alarm, watchdog timer, and interval timer which are all accessible in a byte-wide format. The feature of DS1386P-8K-120 are as follows: (1)8 or 32 kbytes of user NV RAM; (2)integrated NV SRAM, real time clock, crystal, power-fail control circuit and lithium energy source; (3)totally nonvolatile with over 10 years of operation in the absence of power; (4)watchdog timer restarts an out-of-control processor; (5)alarm function schedules real-time related activities such as system wakeup; (6)programmable interrupts and square wave output; (7)all registers are individually addressable via the address and data bus; (8)interrupt signals are active in power-down mode.

The absolute maximum ratings of the DS1386P-8K-120 are: (1)voltage on any pin relative to ground: -0.3V to +7.0V; (2)operating temperature range: 0°C to 70°C; (3)storage temperature range: -40°C to +70°C (-40°C to +85°C for IND parts); (4)soldering temperature: See J-STD-020A Specification.

The following is about the electrical characteristics of DS1386P-8K-120: (1)input leakage current: -1.0A min and +1.0 A max; (2)I/O leakage current CE VIH VCC: -1.0A min and +1.0 A max; (3)output current at 2.4V: -1.0 mA min; (4)output current at 0.4V: 2.1 mA min; (5)standby current CE = 2.2V: 3.0mA typical and 7.0mA max; (6)standby current CE = VCC - 0.2V: 2.0mA typical and 4.0mA max; (7)operating current: 85 mA max; (8)write protection voltage: 4.0V min, 4.25V typical and 4.5 V max.
