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.

I used this chips several times:

I/O port: 8255 intel ( 3x8bit I/O port's (very easy to use))
real time clk: PCF8583 (RTC + 256x8 bit static ram)

Regards!!

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.
