TK68HC11D0 Microcontroller

General Description

The TK68HC711D3 contains highly sophisticated on-chip peripheral functions. This high-speed, low-power programmable read-only memory (PROM) MCU has a nominal bus speed of 3 MHz. The fully static design allows operations at frequencies down to dc.

The TK68HC11D3 and TK68HC11D0 are read-only memory (ROM) based high-performance microcontrollers (MCU) based on the TK68HC11E9 design. The TK68L11D0 is an extended-voltage version of the TK68HC11D0 that can operate in applications that require supply voltages as low as 3.0 V.
