Real Time Clock: PCF8563
If you need to add a clock or timer to your MicroMite (or MaxiMite v4.5) then this is the official RTC that works with MMBasic’s inbuilt RTC commands.
This 8-pin DIP RTC is manufactured by NXP (part no. PCF8563P/F4).
If adding to a MicroMite or MaxiMite you will also require: 1x 32.768KHz crystal, 2x 27pF ceramic capacitors, 2x 4K7 resistors, 1x 3v back-up battery & holder. See User Manual for further details.
This RTC can also be used to Wake the MicroMite at timed intervals – useful for battery powered data-loggers for example. For this you will need: 1x 32.768KHz crystal, 2x 27pF ceramic capacitors, 2x 4K7 resistors, 1x 1M resistor.
