General Description
1.2 Introduction
The MC68HC705J1A is a member of Motorola’s 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 processor unit (CPU) and are available with a
variety of subsystems, memory sizes and types, and package types.
On-chip memory of the MC68HC705J1A includes 1240 bytes of
erasable, programmable read-only memory (EPROM). In packages
without the transparent window for EPROM erasure, the 1240 EPROM
bytes serve as one-time programmable read-only memory (OTPROM).
The MC68HRC705J1A is a resistor-capacitor (RC) oscillator mask
option version of the MC68HC705J1A and is discussed in Appendix A.
MC68HRC705J1A.
A high-speed version of the MC68HC705J1A, the MC68HSC705J1A, is
discussed in Appendix B. MC68HSC705J1A.
The MC68HSR705J1A, discussed in Appendix C. MC68HSR705J1A,
is a high-speed version of the MC68HRC705J1A.
A functional block diagram of the MC68HC705J1A is shown in
Figure 1-1.
