System Controller
General Description
The NS32FX200 NS32FV100 and NS32FX100 are highly
integrated system chips designed for a FAX system based
on National Semiconductor’s embedded processors
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 scan-
ners 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 applica-
tions The NS32FV100 is optimized for thermal paper FAX
machines with Digital Answering Machine support
