2016年8月19日 · Motorola released an upgraded 6801, the MC6801U4 which expanded the timer functions, increased the ROM to 4K, and increased the RAM to 192-bytes. In 1985 the MC6801 was upgraded again, a second 16-bit index register …

The M6800 Microcomputer System (latter dubbed the Motorola 6800 family, M6800 family, or 68xx) [1][2] was a series of 8-bit microprocessors and microcontrollers from Motorola that began with the 6800 CPU.

The MC6801 was a single-chip microcomputer (that today would also be called a microcontroller) incorporating a 6802 CPU with 128 bytes of RAM, a 2 KB ROM, a 16-bit timer, 31 programmable parallel I/O lines, and a serial port.

摩托罗拉68000型中央处理器，或称 MC68000， 680x0， m68000， m68k， 68k； 是由美国 摩托罗拉 公司（Motorola）的 半导体 部门（现已独立成为 飞思卡尔 公司（Freescale））出品的一款16/32位 CISC （复杂指令集） 微处理器。 作为M68K处理器系列的第一个成员，MC68000于1979年投放市场。 由于内部使用32位总线和寄存器，它在软件层（指令集）上基本与随后的纯32位产品保持兼容。 物理内存. 摩托罗拉公司于1976年起動MACSS計畫（Motorola …

2019年7月30日 · According to Wikipedia, The Motorola 6800 was released in 1974. Between that and the release of the 6809 in 1979 (or 1978?) there was at least one other 6800-series CPU released, the 6802 microcontroller with the same registers and instruction set as the 6800.

2022年12月7日 · The MC6801 has a slightly upgraded 6800 CPU, which included a multiply instruction, at the request of the lead customer, General Motors (GM). GM initially used the MC6801 microcontroller for the TripMaster digital trip meter in the 1978 Cadillac Seville.

2017年12月7日 · Hitachi released their version of the 6801 in 1980, with full production commencing in 1981. It was made on a 3-micron NMOS process and was available in both a 1MHz speed (HD6801S0) and 1.25MHz (HD6801S5). Around this time (1982) Hitachi was also transitioning their part numbering system.
