The MC68HC708AS48 is a member of the low-cost, high-performance
M68HC08 Family of 8-bit microcontroller units (MCUs). The M68HC08
Family is based on the customer-specified integrated circuit (CSIC)
design strategy. All MCUs in the family use the enhanced M68HC08
central processor unit (CPU08) and are available with a variety of
modules, memory sizes and types, and package types.
Features of the MC68HC708AS48 include:
1. No security feature is absolutely secure. However, Motorola’s strategy is to make reading or
copying the EPROM/OTPROM difficult for unauthorized users.
