Yes the JHD162A is based on the HD447800.  It follows the "standard" pinout for similar LCDs.  (I just hooked up a JHD162A last night and am using it right now.)

Hey thankyou very much!  ;D
Well I have one more query...I have seen somewhere here in this forum(sorry I don't remember the post) that we have to plugin a 12v adaptor in addition to the usb, for the blocks to be shown on the screen. Will it work with a 9v too?

Thanks for the Peggy link James, The idea of using the HD44780 was that the interface bus is already there and people can treat it as if it were an lcd, well i've lifted a couple of HD44780's and will solder one to a breakout board as soon as it's etched

@P18F4550... yeah, I understand.  I just though it would be of interest.  The more I think about the HD447800, it would be very cool to control a bunch of LEDs.  Post updates on your progress!
