DescriptionThe NS32FX200, NS32FV100 and NS32FX100 are highly integrated system chips designed for a FAX system based on National Semiconductor's embedded processorsÐ NS32FX161, NS32FV16 or NS32FX164. The NS32FX100 is the common core for all three system chips.
The NS32FV100 and NS32FX200 offer additional functions. Throughout this document, references to the NS32FX100 also apply to both the NS32FV100 and the NS32FX200. Specific NS32FV100 or NS32FX200 features are explicitly indicated. The NS32FX200, NS32FV100 and NS32FX100 feature an interface to devices like stepper motors, printers and scanners, a Sigma-Delta CODEC, an elapsed-time counter, a DMA controller, an interrupt controller, and a UART.
The NS32FX200 is optimized for high-end FAX applications, such as plain-paper FAX and multifunctional peripherals. The NS32FX100, is optimized for low-cost FAX applications. The NS32FV100 is optimized for thermal paper FAX machines with Digital Answering Machine support.
