Questions buyers ask
- Can AiP1302 replace DS1302?
- AiP1302 is I-CORE's functional equivalent of DS1302 in the same SOP-8 package. Standard parts in this family share the industry pinout, but please compare both datasheets — supply range, timing and absolute maximum ratings — before design-in.
- What is the supply voltage and temperature range of AiP1302?
- Supply: 2.0–5.5 V. Operating temperature: See datasheet. See the datasheet for full electrical characteristics.
- Is AiP1302 in stock, and can I get a free sample?
- Yes, it is held in stock in Shenzhen. Free samples are available for evaluation, with shipping paid by us. For production orders, SMD parts can be ordered from 1 pc and DIP parts ship in full tubes; orders ship within 2–3 business days after payment.
- Is it original I-CORE product?
- Yes. We supply factory-original I-CORE (Wuxi I-CORE Electronics) parts in sealed reels and tubes. Our ISO 9001, ISO 14001 and ISO 45001 certificates are shown on the home page; RoHS and REACH test reports are available on request.
Datasheet highlights
From the I-CORE English datasheet AiP1302 (revision 2025-01-B2). The full datasheet PDF is linked above.
General description
AiP1302 is a trickle charge clock chip circuit, which includes clock/calendar register and 31-byte data temporary register. The real-time clock/calendar provides information including seconds, minutes, hours, dates, months and years. Leap year can be adjusted by itself. You can choose 12-hour system and 24-hour system, and you can set AM and PM. Data transmission is controlled through three wires: CE, I/O and SCLK.
Key features
- Clock counting function, leap year adjustment valid up to 2100.
- 3-wire transmission
- Built-in 31-byte RAM register
- Operating voltage: 2.0 to 5.5V
- Operating current is less than 400nA (VCC2=2.0V)
- TTL compatible
- Battery or super capacitor (more than 0.1F) can be used for backup power supply.
