Product Summary

The DS1386-32K-150 is a nonvolatile static RAM with a full-function real-time clock (RTC), alarm, watchdog timer, and interval timer that are all accessible in a byte-wide format. The DS1386 contains a lithium energy source and a quartz crystal, which eliminates the need for any external circuitry. Data contained within 8k or 32k by 8-bit memory and the timekeeping registers can be read or written in the same manner as byte-wide static RAM.

Parametrics

DS1386-32K-150 absolute maximum ratings: (1)Voltage Range on Any Pin Relative to Ground: -0.3V to +7.0V; (2)Operating Temperature Range: 0 to +70℃; (3)Storage Temperature Range: -40 to +70℃; (4)Soldering Temperature: See IPC/JEDEC J-STD-020 Specification.

Features

DS1386-32K-150 features: (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.
