MC6803E Datasheet 8-bit Microprocessor

Manufacturer: Motorola Semiconductor (now NXP Semiconductors)

Overview: (AA) MOTOROLA SEMICONDUCTORS 3501 ED BLUESTEIN BLVD., AUSTIN, TEXAS 78721 Advance Information 8-BIT MICROPROCESSOR The MC6803E is an 8-bit microprocessing unit (MPU) designed for uses in which the internal clock needs to be synchronized with systems, peripherals, or other MPUs. The MC6803E also supports DMA and dynamic RAM refresh with its halt (HALT) and bus available (BA) pins.

Key Features

  • of the MC6801 microcomputer unit except on-chip ROM and an on-chip oscillator. These on-chip features include 128 bytes of RAM, a serial communications 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. Enhanced MC6800 Instructi.
