We have developed a simple single-board MCU based on the MC9SAW60CFUE
Features:
. Integrated switching supply, 9-20 VAC input
. AW60 is 5V based
. 24-key keyboard interface ( 8 KBI x 3 scan, active low )
. LCD interface
. RS-485 interface
. All of the GPIO pins are routed to edge pin connectors
. BDM Interface
As a fanatic Freescale junkie, and because you have a small company ( we were all small once), I will let you have the schematics, Gerbers, etc. which you will need to construct the board free of charge.
I am in a good mood, and is Xmas anyway - I will even let you have a blank PCB which you can use to construct the MCU.
See pics attached.
Let me know if you want it.
