OR:  

The PCA8565A is a CMOS1 Real-Time Clock (RTC) and calendar optimized for low power consumption. A programmable clock output, interrupt output, and voltage-low detector are also provided. All addresses and data are transferred serially via a two-line bidirectional I2C-bus. Maximum bus speed is 400 kbit/s. The built-in word address register is incremented automatically after each written or read data byte.

AEC-Q100 compliant for automotive applications.

Features and benefits

  • Provides year, month, day, weekday, hours, minutes, and seconds based on 32.768 kHz quartz crystal
  • Clock operating voltage: 1.8 V to 5.5 V
  • Extended operating temperature range: -40 °C to +125 °C
  • Low backup current: typical 0.65 mA at VDD = 3.0 V and Tamb = 25 °C
  • 400 kHz two-line I2C-bus interface (at VDD = 1.8 V to 5.5 V)
  • Programmable clock output for peripheral devices (32.768 kHz, 1.024 kHz, 32 Hz, and 1 Hz)
  • Alarm and timer functions
  • Two integrated oscillator capacitors
  • Internal Power-On Reset (POR)
  • I2C-bus slave address: read A3h; write A2h
  • Open-drain interrupt pin
  • Century flag

Applications

  • Automotive
  • Industrial
  • Applications that require a wide operating temperature range

NXP Semiconductors' products are specifically designed and manufactured to be used within the electrical, thermal, mechanical and other parameters set forth in NXP Semiconductors' data sheets. Quality and reliability data provided by NXP Semiconductors, such as MTBF, MSL and FIT, is intended to be a non-binding estimate of product performance based upon diffusion process, history only. It does not imply that any performance levels reflected in such data can be met if the product is operated outside the conditions expressly stated in the latest published data sheet for a device or in your application.

The RoHS data provided hereunder is preliminary and non binding for NXP Semiconductors. NXP Semiconductors does not accept any liability related to this data.

NXP Semiconductors products are not designed, authorized or warranted to be suitable for use in medical, military, aircraft, space or life support equipment, nor in applications where failure or malfunction of an NXP Semiconductors product can reasonably be expected to result in personal injury, death or severe property or environmental damage nor for any other use that is not explicitly agreed between the parties.

Any use of NXP Semiconductors' products beyond the scope defined in the current NXP Semiconductors' data sheet voids all warranty responsibility of NXP Semiconductors with respect to such devices, and also voids all responsibility of NXP Semiconductors with respect to any applications assistance, product design, software performance or services of any kind that were or may have been performed in connection with the sale of any such devices.

Further, resale of NXP Semiconductors' products or services with statements different from or beyond the parameters stated by NXP Semiconductors for that product in official NXP Semiconductors data sheets, or without the warnings or instructions provided by NXP Semiconductors, voids all express and any implied warranties for the associated NXP Semiconductors product or service, and is an unfair and deceptive business practice.
