SECTION 1
GENERAL DESCRIPTION
The MC68HC05JB3 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-specied 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 MC68HC05JB3 is specically designed to be used in applications where a
low speed (1.5Mbps) Universal Serial Bus (USB) interface is required.
