MC6803E
features of the MC6801 microputer unit except on-chip ROM and an on-chip oscillator. These on-chip features include 128 bytes of RAM, a serial munications interface (SCI), parallel |/O, and a three-function programmable timer. The MC6803E has the same enhanced MC6800 features as the MC6801, which include 64K addresss space, two 8-bit accumulators (which can be concatenated into one 16-bit accumulator), and the enhanced instruction set, as well as extra internal interrupts.
