APPENDIX C
MC68040V AND MC68EC040V
The MC68040V and MC68EC040V are Motorola’s 3.3 volt, static versions of the
MC68040 third-generation, M68000-compatible, high-performance, 32-bit microprocessor.
They require a 3.3V power supply providing over 50 percent reduction in power
consumption compared to a 5.0V device. The maximum power used at 3.3 volts is 1.5
watts at an operating frequency of 33 MHz. They also have a low-power stop mode. Once
in this state, both devices remain quiescent, consuming less than 330 W of power. The
low-power usage of these microprocessors makes them an ideal choice for portable
computing and power constrained applications.
The MC68040V programming model, data formats and types, instruction set, caches, and
MMUs are the same as those described for the MC68LC040 in Appendix A MC68LC040.
The MC68EC040V programming model, data formats and types, and instruction set are
the same as those described for the MC68EC040 in Appendix B MC68EC040. However,
both devices contain additional features:
