The P2 RTC Add-On Board provides a real time clock with calendar and alarm functionality to the Propeller 2 (P2X8C4M64P) multicore microcontroller. The small RTC board includes a rechargeable lithium battery that is kept charged while the RTC is powered and will allow the RTC to keep time while power is disconnected.

  • This add-on board is compatible with any standard single Parallax P2 accessory socket found on most P2 development boards. The connector is a standard 2×6-way 0.1” pitch socket, and the board could be used with a wide range of microcontrollers employing 3.3 V signal levels.
  • The P2 RTC Add-on extends the timekeeping capabilities of the Parallax P2 multicore microcontroller, and enables date and timestamp capabilities that are important in many projects, including data and file system management, user display, control and IoT integration.

Features:

  • Based on the PCF8523 CMOS Real-Time Clock (RTC) with calendar
  • Optimized for low power consumption
  • Data is transferred serially via an I2C-bus with a data rate up to 1000 kbit/s
  • Alarm and timer functions
  • Events can generate a wake-up signal on an interrupt pin
  • Offset register allows fine-tuning of the clock
  • Backup battery switchover circuit detects power failures and automatically switches to the battery supply when a power interruption occurs
  • 2×6-pin female socket with 0.1” spacing compatible with the standard Parallax P2 single Accessory sockets

Specifications:

  • Supply voltage: +3.3 VDC
  • Control interface: I2C bus (100, 400, 1000 kHz)
