MC68HC05X16
31232 bytes of user ROM plus 16 bytes of user vectors
528 bytes of RAM
654 bytes of bootstrap ROM
Available in 64-pin QFP package
High speed operation (4 MHz bus speed) available. See
characteristics.
– 40 to +125 C temperature range
Important note
The following applies to the D53J MC68HC05X32 mask set only:
On the D53J mask set, DIV10 is forced in bootstrap mode. On later mask set
revisions, including D69J, DIV2 is forced in bootstrap mode.
– Mask options on the MC68HC05X32 allow the customer to

Freescale Semiconductor, Inc.
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.
