GENERAL DESCRIPTION
The MC68HC05J5A is a member of the low-cost high-performance M68HC05
Family of 8-bit microcontroller units (MCUs). The M68HC05 Family is based on
the customer-specified integrated circuit design strategy. All MCUs in the family
use the popular M68HC05 central processing unit (CPU) and are available with a
variety of subsystems, memory sizes and types, and package types.
The MC68HC05J5A is an enhanced version of the MC68HC05J5, with expanded
RAM, ROM sizes, and an additional 16-bit timer with TCAP. This MCU is available
in 20-pin PDIP, 20-pin SOIC, 16-pin PDIP, and 16-pin SOIC packages. The 16-pin
version has four less I/O lines.
Three variation on the MC68HC05J5A device are available; a summary of their
differences are listed in the following table:
