Description

The DS12C887+ belongs to the DS12C887 series. It is a real-time clock and it provides a real-time clock/calendar,one time-of-day alarm, three maskable interrupts with a common interrupt output,a programmable square wave,and 114 bytes of battery-backed static RAM. It can be uitilized in applications such as embedded systems,utility meters,security systems,network hubs,bridges and routers. It is available in Optional Encapsulated DIP (EDIP) package with integrated crystal and battery.

There are some features of DS12C887+ as follows. (1) binary or BCD time representation; (2) daylight saving time option; (3) selectable Intel or Motorola bus timing; (4) interfaced with software as 128 RAM locations; (5) 14 bytes of clock and control registers; (6) RAM clear function; (7) interrupt output with three independently maskable interrupt flags; (8) time-of-day alarm once per second to once per day; (9) periodic rates from 122 s to 500ms; (10) end-of-clock update cycle flag; (11) programmable square-wave output; (12) automatic power-fail detect and switch circuitry; (13) underwriters laboratory (UL) recognized.

What comes next is about the absolute maximum ratings of DS12C887+. (1): voltage range on VCC pin relative to ground is from -0.3 V to 6.0 V; (2): operating temperature range is from 0 to 70 ; (3): storage temperature range is from -55 to 125 ; (4): soldering temperature (leads, 10s) is 260 . Then is the DC characters at VCC is from 4.5 V to 5.0 V. (1): VBAT input voltage (VBAT) is from 2.5 V to 4.0 V; (2): the maximum VCC power-supply current is 15 mA; (3): the typical power-fail voltage is 4.25 V,the minimum is 4.0 V and the maximum is 4.5 V.
