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 FDI’s support page. 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.
It supports two different RTC options in a TSSOP-14 package:
- PCF2123
- PCA2125
A small USB based ICP programmer that allows ICP programming of the P89LPC932A1 and many other NXP microcontrollers from any PC is available from FDI.
