O.K. Here's everything I know about different versions of MC68HC11s:
I think the MC68HC811A8 is the greatest, but I don't know what it costs.

| PART NUMBER | EPROM | ROM | EEPROM | RAM |  Comments                         |
+------------------------------------------------------------------------------+
| MC68HC11A8  |  ---  |  8K |   512  | 256 | Family built around this device   |
| MC68HC11A1  |  ---  | --- |   512  | 256 | 'A8 with ROM disabled             |
| MC68HC11A0  |  ---  | --- |   ---  | 256 | 'A8 with ROM and EEPROM disabled  |
| MC68HC811A8 |  ---  | --- | 8K+512 | 256 | EEPROM emulator for 'A8           |
| MC68HC11E9  |  ---  | 12K |   512  | 512 | 4 input capture, 512 ram, 12K ROM |
| MC68HC11E1  |  ---  | --- |   512  | 512 | 'E9 with ROM disabled             |
| MC68HC11E0  |  ---  | --- |   ---  | 512 | 'E9 with ROM and EEPROM disabled  |
| MC68HC811E2 |  ---  | --- |    2K  | 256 | No ROM part for expanded systems  |
| MC68HC711E9 |  12K  | --- |   512  | 512 | One-time programmable version 'E9 |
| MC68HC11D3  |  ---  |  4K |   ---  | 192 | Low cost 40-pin version           |
| MC68HC711D3 |   4K  | --- |   ---  | 192 | One-time programmable version 'D3 |
| MC68HC11F1  |  ---  | --- |   512  | 1K  | Non-multiplexed 68-Pin            |
| MC68HC11K4  |  ---  | 24K |   640  | 768 | >1Meg memory space PWM, CS, 84-Pin|
| MC68HC711K4 |  24K  | --- |   640  | 768 | One-time programmable version 'K4 |
| MC68HC11L6  |  ---  | 16K |   512  | 512 | Like the 'E9 more ROM, I/O 64/68  |
| MC68HC711L6 |  16K  | --- |   512  | 512 | One-time programmable version 'L4 |

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 48 pin DIP  is "P"
6) There are a million versions of all these. 2, 3, and 4 MHZ BUS speeds
   and a lot of other things. I have a "Motorola roadmap" that lists 36
   different suffixes.
7) There is an 'N4 version with 24K ROM, 768 RAM, 640 EEPROM, 8-bit A/D,
   8-bit D/A, 6 PWMs, 16 bit math co-processor, 62 bits of I/O and a 4MHZ
   non-multiplexed bus. Good luck finding this guy!
