Hi,

I need to use in my project an extra I/O port chips, a real time clock and if possible a LCD display (I know this was available in past from Philips and production stoped)
Any advice for a low cost widely used LCD didplay is welcome.

I have no problem to find those chips but would like to use components that are widely used on and not expensive.

Any advice is very welcome.

If you are using I2C bus.
I recomended to use 8 bits I/O expander PCF8574 or PCF8574A,
and using 2 chips for control and data bus to connect with parallel
LCD. module.
