Working Principle
Same MACH4 architecture as M4A3-64/32 but with 96 macrocells across 6 logic blocks and 48 I/O pins. The additional logic and I/O capacity supports more complex designs such as PCI bus interfaces, multi-channel address decoders, and cascaded state machines. The central routing pool maintains 100% inter-block connectivity. 3.3V core with 5V-tolerant I/O supports mixed-voltage system integration. JTAG ISP allows field firmware updates.
Applications
- PCI interfacing
- Complex state machines
- Multi-bus control
- Address decoding
