Product description

The PCF8593 is a CMOS1 clock and calendar circuit, optimized for low power consumption. Addresses and data are transferred serially via the two-line bidirectional I²C-bus. The built-in word address register is incremented automatically after each written or read data byte. The built-in 32.768 kHz oscillator circuit and the first 8 bytes of the RAM are used for the clock, calendar, and counter functions. The next 8 bytes can be programmed as alarm registers or used as free RAM space.

Features

  • I²C-bus interface operating supply voltage: 2.5 V to 6.0 V
  • Clock operating supply voltage 1.0 V to 6.0 V at 0 ℃ to +70 ℃
  • 8 bytes scratchpad RAM (when alarm not used)
  • Data retention voltage: 1.0 V to 6.0 V
  • External RESET input resets I²C interface only
  • Operating current (at fSCL = 0 Hz, 32 kHz time base, VDD = 2.0 V): typical 1 μA
  • Clock function with four year calendar
  • Universal timer with alarm and overflow indication
  • 24 hour or 12 hour format
  • 32.768 kHz or 50 Hz time base
  • Serial input and output bus (I²C-bus)
  • Automatic word address incrementing
  • Programmable alarm, timer, and interrupt function
  • Space-saving SO8 package available
  • Slave addresses: A3h for reading, A2h for writing

Your use of this data, and all consequences of such use, is solely your responsibility. You must perform sufficient engineering and additional qualification testing in order to properly evaluate your application and determine whether a candidate NXP Semiconductors device is suitable for use in that application.

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.
