}} introduced in 1974. | |||
It requires +5 V | It requires a +5 V supply only (generating bias voltages on chip) and came initially in 40-pin DIL packages. The 6800 has non-multiplexed data (8 bit) and address (16 bit) buses, and requires an external non-overlapping two-phase 0.1 − 1 MHz clock (later versions from 1976 on up to 2 MHz). | ||
The '''6802''', introduced in 1977, includes 128 bytes RAM and an internal clock oscillator. The '''6808''' is the same without RAM. | |||

The '''68HC11''', introduced in 1984, is an upward-compatible microcontroller that adds a second index register, 8x8 multiply and 16/16 divide instructions, as well as a range of 16-bit instructions that treat A and B as a combined 16-bit accumulator. On-chip peripherals include timers, parallel ports, A/D, SPI and UART. | |||
