General Description
The NS32FX200, NS32FV100 and NS32FX100 are highly
integrated system chips designed for a FAX system based
on National Semiconductor’s embedded processorsD
NS32FX161, NS32FV16 or NS32FX164. The NS32FX100 is

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.

chips.
The
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.
