The NXP RTC Demo PCF2123 is a reference design for a low power Real Time Clock and LCD
solution with an available I2C temperature sensor. The Demo Board is controlled by a simple
two-button user interface (MODE and SELECT). Example code for several sample applications: a
programmable time and date display, a programmable countdown timer, and a repeating pattern of
text lines, can all be found on the website at www.teamFDI.com/RTCDemoPCF2123. The user
can edit this code and download to the reprogrammable Flash microcontroller via a 10-pin header
included on the board using any external ICP style programmer.
A small USB based ICP programmer that allows ICP programming of the P89LPC932A1 and
many other NXP microcontrollers from any PC is available from Future Designs, Inc. Details can
be found at www.teamfdi.com/USB-ICP.
Highlights
• Low power, SPI based Real Time Clock driven by a 32.768 KHz quartz crystal
• Supports Two Different RTC Options in a TSSOP-14 Package
• Available Low Power LM75B I2C Temperature Sensor
• Powered by a single 3V coin cell battery
• 8-character alphanumeric LCD
• I2C based LCD driver with 128 segment support
• Two miniature push-buttons for user control; additional User Interface via header
• User reprogrammable via 10-pin ICP header
