The MC68HC705B16 is a device similar to the MC68HC05B6, but
with increased RAM and 15 kbytes of EPROM instead of 6
kbytes of ROM. In addition, the self-check routines
available in the MC68HC05B6 are replaced by bootstrap
firmware. The MC68HC705B16 is an OTPROM (one-time
programmable ROM) version of the MC68HC05B16, meaning that
once the application program has been loaded in the EPROM it
can never be erased. 
Features:
* 15 kbytes EPROM
* 352 bytes of RAM
* 576 bytes bootstrap ROM
* Simultaneous programming of up to 8 bytes of EPROM
* Optional pull-down resistors available on all port B and port C pins
* 52-pin PLCC and 64-pin QFP packages
