Description
This article introduces the DS17485S-3+ electronic component model, which belongs to the real-time clocks (RTC) product category, and is designed to be the successor to the industry-standard DS12885 and DS12887. The DS17485S-3+ 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 NV SRAM.
Specifications and features
- Industry-standard DS12887 PC clock with enhanced functions
- RTC counts seconds, minutes, hours, day, date, month, and year with leap year compensation through 2099
- Optional +3.0V or +5.0V operation
- SMI recovery stack
- 64-bit silicon serial number
- Power-control circuitry supports system power-on from date/time alarm or key closure
- Crystal select bit allows operation with 6pF or 12.5pF crystal
- 12-hour or 24-hour clock with AM and PM in 12-hour mode
- 114 bytes of general-purpose, battery-backed NV SRAM
- Extended battery-backed NV SRAM
- 2048 bytes (DS17285/DS17287)
- 4096 bytes (DS17485/DS17487)
- 8192 bytes (DS17885/DS17887)
- RAM clear function
- Interrupt output with six independently maskable interrupt flags
- Time-of-day alarm once per second to once per day
- End of clock update cycle flag
- Programmable square-wave output
- Automatic power-fail detect and switch circuitry
- Available in PDIP, SO, or TSOP package (DS17285, DS17485, DS17885)
- Optional encapsulated DIP (EDIP) package with integrated crystal and battery (DS17287, DS17487, DS17887)
- Optional industrial temperature range available
- Underwriters Laboratory (UL) recognized
Application Scenarios
The DS17485S-3+ electronic component model can be widely used in real-time clock applications that require clock/calendar and time-of-day alarm processing, such as industrial controllers, meters, and computer peripherals.
Comparison
Advantages- Incorporates industry-standard DS12887 PC clock with enhanced functions
- RTC counts seconds, minutes, hours, day, date, month, and year with leap year compensation through 2099
- Optional +3.0V or +5.0V operation
- Provides programmable square wave and 114 bytes of battery-backed NV SRAM
Disadvantages- Not suitable for applications that require larger battery-backed NV SRAM
- DS17287, DS17487, and DS17887 variants are available only in encapsulated DIP package, which may limit the selection of package type
