9S12DP256

Sockets and Adapters

Package: 112 pin LQFP with 0.65mm (25.9mil) pitch with a 20mm x 20mm x 1.6mm body size. Motorola said to contact Ironwood Electronics, Electronic Hardware, Ltd., or Emulation Technology, for sockets. Omega research seems to have a universal (solder on) adapter. Nepenthe has a QP1-112-065-100 LQFP112 0.65 pitch clamshell socket.

Yamaichi IC51-1124-1036-2

Winsolow WA11265DQAET is an solder on adapter from QFP112(0.65mm) to PGA112(0.1inch)

qfp-adapter.com 112QFS26-SD is a solder in test probe that replaces a QFP (Price: $133).

Asystelectronics IA112TQ-SOLDER is a solder down adapter which gives pins an emulator can attach to.

Bugs

There is a BUG in MC9S12DP256 mask sets 0K36N, 0K79X and 1K79X that can result in loss of SCI interrupts if a transmit and receive interrupt occur simultaneously!

Monitor

Motorola makes a monitor called D-BUG12 that runs on this chip and allows you to debug programs including a single line assembler/dissassembler and the ability to function as a BDM host to another board. However, the debugger does not allow you to use any of the onchip flash memory for your own program.

Misc

__asm__ __volatile__ (" cli ");

void __premain() is apparently called before main()?
