General Description
1.1 Introduction
The MC68H(R)C908JL3E 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.
A list of MC68H(R)C908JL3E device variations is shown in Table 1-1.
