MC68HC05B32
The MC68HC05B32 is a device similar to the MC68HC05B6, but with increased RAM and ROM
sizes. The entire MC68HC05B6 data sheet applies to the MC68HC05B32, with the exceptions
outlined in this appendix.
G.1
Features
• 31248 bytes User ROM
• No page zero ROM
• 528 bytes of RAM
• 52-pin PLCC and 64-pin QFP packages for -40 to +85°C operating temperature range
(extended)
• 56-pin SDIP package for 0 to 70°C operating temperature range
• High speed version not available
Note:
Preliminary electrical specifications for the MC68HC05B32 should be taken as being
similar to those for the MC68HC705B32. When silicon is fully available, the part will be
re-characterised and new data made available.
G.2
External clock
When using an external clock the OSC1 and OSC2 pins should be driven in antiphase (see
Figure D-2). The t_OXOV or t_ILCH specifications (see Section H.9) do not apply when using an
external clock input. The equivalent specification of the external clock source should be used in
lieu of t_OXOV or t_ILCH.
