General Description
The NS32FX200, NS32FV100and NS32FX100are highly
integrated system chips designedfora FAX system based National Semiconductor’s embedded processorsÐ
NS32FX161, NS32FV16or NS32FX164.The NS32FX100is
the common coreforall three system chips. The
NS32FV100 and NS32FX200 offer additional functions.
Throughoutthis document, referencestothe NS32FX100
also applyto boththe NS32FV100 andthe NS32FX200.
Specific NS32FV100or NS32FX200 featuresare explicitly
indicated.
The NS32FX200, NS32FV100 and NS32FX100 featurean
interfaceto deviceslike stepper motors, printersand scan-
ners,a Sigma-Delta CODEC,an elapsed-time counter,a
DMA controller,an interrupt controller,anda UART.
The NS32FX200is optimized forhigh-end FAX applications,
suchas plain-paper FAX and multifunctional peripherals.
The NS32FX100,is optimizedfor low-cost FAX applica-
tions. The NS32FV100is optimizedfor thermal paper FAX
machines with Digital Answering Machine support.
Features Direct interfaceto the NS32FX161, NS32FV16 and
NS32FX164 embedded processors Supportsa varietyof Contact Image Sensor (CIS)and
Charge Coupled Device (CCD) scanners Direct interfacetoa varietyof Thermal Print Head
(TPH) printers. Bitmap shifterand DMA channels facili-
tatethe connectionof other typesof printers Supportstwo stepper motors Direct interfaceto ROM and SRAM.The NS32FX200
and NS32FV100,in addition, interfaceto DRAM
devices Programmable wait state generator Demultiplexed addressand data buses Multiplexed DRAM address bus (NS32FX200 and
NS32FV100) Supports3V freeze modeby maintaining only elapsed
time counter Controlof power consumptionby disabling inactive
modulesand reducingthe clock frequency Operating frequency Normal mode: 19.6608 MHzÐ24.576 MHzin steps 1.2288 MHz. (NS32FX200) Normal mode: 19.6608 MHzÐ24.576 MHzin steps 1.2288 MHz. (NS32FV100) Normal mode: 14.7456 MHzÐ19.6608 MHzin steps 1.2288 MHz. (NS32FX100) Power Save mode: Normal mode frequency divided sixteen On-Chipfull duplex Sigma-Delta CODEC with: Total harmonic distortion better than b70dB Programmable hybrid balance filter Programmable reception and transmission filters Programmable gain control On-Chip Interrupt Control Unit with:16 interrupt sources Programmable triggering mode On-Chip counters, WATCHDOGTM, UART,
