9S12BC32 vs 9S12C32 - hc08jb8 - Jan 21 12:24:00 2004

Hi I am trying to get the actual difference between the BC32 and the new C32, I tried using the Motorola website's product comparison, but the page hangs. Apart from the obvious price difference, is there something I am missing out? Jay |

There are a lot of detail differences. The 68HC912BC32 is a "HC-12" part.
The MC9S12C32 is a "HCS-12" part. See Motorola EB376 for documentation on the general differences between HC-12 and HCS-12 parts. It is available at: http://e-www.motorola.com/files/microcontrollers/doc/eng_bulletin/EB376.pdf Even though this is specifically about the MC9S12DP256 it covers most of the differences. You will also need to study the documentation for the MC9S12C32 for the details about the on-chip IO devices and flash memory, which may differ in detail from the MC9S12DP256. Hope this helps.

I played around with 9S12C32 - 80 pin version. - Emulated EEPROM using FLASH. Means that EEPROM can be of any size. - Flash Memory from 32Kbyte to 128Kbyte - Ram Memory from 2K to 4Kbyte - Single CAN - Faster Speed - Longer FLASH burn/erase cycle - Multiple package size from 48 to 80 pin - No Vfp required 912BC32 - Single CAN - Limited EEPROM size - Limited 32Kbyte FLASH - Limited FLASH burn/erase cycle - Slower speed - Single package size 80 pin version only - Requires Vfp |
