MC68HC05X32
Important note
The following applies to the D53J MC68HC05X32 mask set only:
– Mask options on the MC68HC05X32 allow the customer to
select POR delay cycles and oscillator DIV ratio. However,
during reset, options of 4064 cycles POR and DIV 10 are
forced, regardless of which options the customer has selected.
Therefore, a power-on reset delay of 40640 oscillator cycles is
forced.
On the D53J mask set, DIV10 is forced in bootstrap mode. On later mask set
revisions, including D69J, DIV2 is forced in bootstrap mode.
The MC68HC05X32 is a device similar to the MC68HC05X16, but with increased RAM and ROM
sizes. The entire MC68HC05X16 data sheet applies to the MC68HC05X32, with the exceptions
outlined in this appendix.
