Description

The Controller contains an internal CXD9450 Processor with a 16-MB address space and dedicated circuitry optimized for facsimile image processing and monitoring and for thermal or thermal transfer printer support.

The CXD9450 provides fast instruction (up to 10 MHz clock speed) execution and memory efficient input/output bit manipulation. The CPU connects to other internal functions over an 8-bit data bus and 24-bit address bus and dedicated control lines.

The 24-bit external address bus CXD9450, 8-bit data bus, control, status, and decoded chip select signals support connection to external ROM, SRAM, DRAM, and FLASH memory.
