Product description

The PCF8583 is a clock and calendar chip, based on a 2048 bit static CMOS1 RAM organized as 256 words by 8 bits. 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. Address pin A0 is used for programming the hardware address, allowing the connection of two devices to the bus without additional hardware.

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. The remaining 240 bytes are free RAM locations.

Features

  • I²C-bus interface operating supply voltage: 2.5 V to 6 V
  • Clock operating supply voltage 1.0 V to 6.0 V at 0 ℃ to +70 ℃
  • 240 × 8-bit low-voltage RAM
  • Data retention voltage: 1.0 V to 6.0 V
  • Operating current (at fSCL = 0 Hz): max 50 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
  • Slave addresses: A1h or A3h for reading, A0h or A2h for writing

Your use of this data, and all consequences of such use, is solely your responsibility.

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.
