As with all new chips, the B32 is going through a final test phase. The next step is the MC series, which means Motorola certifies that the chip is good. We have all been using the XC version of the 68HC812A4 for a while with very favorable results. The B32 looks just as robust. The B32 variant, as you will see in my discussion of the part, is going to be a great robot controller.
Lets look at the details.
BDLC interface Basically, most of the cool features of the A4 variant of the chip are on this version with the addition of the PWM module. The chip can operate several different bus models. First, it runs great in a single chip configuration. For those applications that need more memory, the external bus can be enabled. Unlike the A4, the B32 has a multiplexed bus.
