Description
The DS1343/DS1344 low-current real-time clocks (RTCs) are specifically designed to provide accurate timing information and consume low power. The DS1344E-33+ is a member of the DS1343/DS1344 family of low-current RTCs and can be used as a replacement for the DS1343. It supports high-ESR crystals which broaden the pool of usable crystals for the devices. The device provides seconds, minutes, hours, day, date, month, and year information, including corrections for leap year.
Specifications and features
- Low timekeeping current of 250nA (typ)
- Compatible with crystal ESR up to 100kΩ
- RTC counts seconds, minutes, hours, day, date, month, and year with leap year compensation valid through 2099
- Power-fail and switch circuitry
- Three operating voltages: 1.8V ±5%, 3.0V±10%, and 3.3V ±10%
- Trickle-charge capability
- Maintain time down to 1.15V (typ)
- Support Motorola SPI modes 1 and 3, or standard 3-wire interface
- Burst mode for reading/writing successive addresses in clock/RAM
- 96-byte battery-backed NV RAM for data storage
- Two time-of-day alarms with two interrupt outputs
- Industrial temperature range
- 20-Pin TSSOP or 14-Pin TDFN package
- Underwriters Laboratories (UL) Recognized
Application Scenarios
The DS1344E-33+ can be used in various applications including medical devices, handheld devices, telematics, and embedded timestamping.
