The 68HC11 is a microcontroller from Motorola, they are used extensively in
controller applications. They have a built in serial interface, 8 ADC channels,
24 digital output pins, several timers and other gadgets. They are available
in several packages, PLCC's and DIPs, check the following list for numbers.

A couple of weeks ago Alan Kilian sent a complete (?) list of 68HC11 versions, 
I will repeat that one here.

O.K. Here's REALLY everything I know about different versions of MC68HC11s:
If you have any corrections or additions to this list PLEASE Email me and
I will correct it.

Notes:
1) On the E2, and F1 parts the EEPROM is relocatable to the top of any 4K page.
   Relocation is done with the upper 4 bits of the CONFIG register.
2) I think the L6 part comes in 64 or 68 pin versions.
3) The E9 part only comes in 52 pin PLCC
4) The A8 comes in either 52 pin PLCC or 48 pin DIP. 
   On the 48 pin DIP version Port E bits 4,5,6,7 (Analog inputs 4,5,6,7) are
   not available. That's where they get the extra 4 pins from.
5) The suffix for 52 pin PLCC is "FN"
   The suffix for 52 pin ceramic window is FS
   The suffix for 48 pin DIP  is "P"
