Hi All, Does anyone know if there will be a variant of HCS12 with non-multiplexed memory in the future? It seems to me that the only option is to use HC16, but this a little different, does not have so much flash and may be an unpopular choice. I have used this controller and find

Hello All, I burned a s2 file with metrowerks tool and tried to flash program it into the micro using P&E PROG12Z programmer. I realized that I need to use an app called SRecCvt from Motorola to convert my s2 file into a linear s file first. Could anybody please tell me the command line that I hav

We have been using the CABLE12 interface cable to program a 68HC12 target for the last year. We use the Cosmic compiler to generate .H12 files which are then downloaded to the Flash and EEPROM (using Cosmic's ZAP) of the MC912 processor on our product. We would like to be able

Hello, I am relatively new to the 68HC12 (about 5 months) and I'm using it in a project that I've been working on. I know that the 68HC12 has an external addressing scheme that will allow one to reach 1MBytes worth of data. My question is this: What types of external memories are available? I have found an I2C 1Mbit EEPROM and some SPI flash memories, but nothing near 1MBytes that I...

Does anyone know of a one-step method to program a 9s12D64? We can only get PEMicro to load Flash or EEPROM, but not both, even with extra documentation from their web site. (see the thread "9S12D64 and P&E Micro's Cyclone Pro" for the continuing saga of frustration. BTW, why does management get so pushy ONLY when they are ready to start producing, even though they knew programming was nee...
