2 / 16 page Engineering Bulletin EB381 2 MOTOROLA Migrating to the MC68HC11F1 For current MC68HC811E2 users with external memory systems (expanded mode operation), the MC68HC11F1 is a possible replacement part (see Table 1). The MC68HC11F1 can address 64 Kbytes of external memory in expanded mode and requires less glue logic than the MC68HC811E2. Other advantages of migrating to the MC68HC11F1 are: • More RAM • More expanded mode input/output (I/O) • Non-multiplexed address/data bus • 3-volt operation • Ability to run at higher speeds For complete information on the MC68HC811E2, see the M68HC11E Family Technical Data, Motorola document order number M68HC11E/D. For information on the MC68HC11F1, see the MC68HC11F1 Technical Data, Motorola document order number MC68H11CF1/D. Both can be found at http://motorola.com/semiconductor (the Motorola World Wide Web site). Major Differences The major differences between these two parts are: • Package options • Memory map (memory, registers, etc.) • EEPROM block protect • CONFIG register • External glue logic requirements Freescale Semiconductor, Inc.
