Hi,
I bought an CFAH2002AYMCJP module a few years back which I retired when I bought my CF633.
I am putting together a Z80 based system and am looking at using the old LCD as a display for it.
The Z80 is clocked at 8Mhz, I am setting the module up as a Port-IO device and was wondering if the module would like being driven on an 8Mhz system.
I am asking because of a refrence in the HD44780U datasheet that reads... ' Correspond to high speed MPU bus interface - 2 MHz (when VCC = 5V) '
Oh, also is the 'E' pin active HIGH or LOW? I cant work out the H,H->L thing in the datasheet
Thanks
