TK68HC05J1A Microcontroller

General Description

The TK68HC05J1A is a member of the low-cost, high-performance TK68HC05 Family of 8-bit microcontroller units (MCU). The TK68HC05 Family is based on the customer-specified integrated circuit (CSIC) design strategy. All MCUs in the family use the popular TK68HC05 central processor unit (CPU) and are available with a variety of subsystems, memory sizes and types, and package types.

On-chip memory of the TK68HC05J1A includes:

1240 bytes of user read-only memory (ROM)
64 bytes of user random-access memory (RAM)

Information on the TK68HCL05J1A, a low-power version of the TK68HC05J1A, is introduced in Appendix A. MC68HCL05J1A of the TK68HC05J1A Family Technical Data Sheet.

Information on the TK68HSC05J1A, a high-speed version of the TK68HC05J1A, is introduced in Appendix B. TK68HSC05J1A of the TK68HC05J1A Family Technical Data Sheet.
