Programming of the flash is greatly simplified over previous HC12s. The
read / verify / re-pulse programming algorithm is replaced by a much
simpler method.
The most significant change resulting from the new flash technology is
that the bulk erase and program times are now fixed. The erase time is
at least twice as fast while the word programming time is at least 20%
faster.
The new flash does not require an external high voltage supply. All
voltages required for programming and erase are now generated
internally. Pin 97 (112 QFP) or pin 71 (80 QFP) is now a test pin for the
flash arrays. Applying 12V to this pin can damage the device. On early
production devices it is recommended that this pin is not connected
within the application, but it may be connected to VSS or 5.5V max
without issue.
Like the flash, the EEPROM is also made from this new NVM
technology. The architecture and basic programming and erase
operations are unchanged. However, there is a new optional
programming method that allows faster programming of the EEPROM.
The first major difference on the new EEPROM is that it requires a
constant time base source to ensure secure programming and erase
operations. The clock source that is going to drive the clock divider input
is the external clock input, EXTALi. The divide ratio from this source has
