• Manufacturer Part Number: AN2727
• Description: Designing Hardware for the HCS12 D-Family
• Manufacturer: Freescale Semiconductor / Motorola

Connecting Capacitors Directly to Output Pins
Pin Out All D-Family Members except DB128
Pin Out 9S12DB128 in 80 Pin
With the exception of the D32, the 80-pin variant uses the same die as the 112-pin variant. This is not a
direct consideration at the hardware design stage as such; however, the application software must
configure undefined inputs on port lines that are not bonded out on the 80-pin device, to avoid unexpected
I/O IDD. Details of this can be found in the “80-pin Package Pitfalls” section at the end of Engineering
Bulletin EB386.
