Motorola 68HC11
The Motorola 68HC11 (P/N 156-5472-01) is an 8-bit microcontroller monolithic integrated circuit introduced in 1984.
The 68HC11 is capable of operating as a single-chip microcontroller executing from internal ROM, or in "expanded multiplexed" mode in which I/O pins are used for a full 8-bit, 64K-address space bus. Onboard resources include ROM, RAM, EEPROM, timers, parallel ports, A/D, and serial ports as both SCI (Serial Communication Interface aka UART) and SPI (Serial Peripheral Interface). A nonvolatile configuration register controls whether certain memory resources are enabled, so that, for example, a mask ROM part can have its ROM disabled and code executed from external memory instead. Even in the case of expanded-multiplexed operation in which the code store is external (e.g. EPROM), the internal EEPROM may be used e.g. for storing calibration data.
