• Manufacturer Part Number: mc68hc05jb4p
• Description: Mc68hc705jb4 Microcontroller
• Manufacturer: Freescale Semiconductor, Inc

1.1
The MC68HC05JB4 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 (CSIC) 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 MC68HC05JB4 is specifically designed to be used in applications where a
low speed (1.5Mbps) Universal Serial Bus (USB) interface is required.
