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.

■ Direct interface to the NS32FX161, NS32FV16 and NS32FX164 embedded processors
■ Supports a variety of Contact Image Sensor (CIS) and Charge Coupled Device (CCD) scanners
■ Direct interface to a variety of Thermal Print Head (TPH) printers. Bitmap shifter and DMA channels facilitate the connection of other types of printers
■ Supports two stepper motors
■ Direct interface to ROM and SRAM. The NS32FX200 and NS32FV100, in addition, interface to DRAM devices
■ Programmable wait state generator
■ Demultiplexed address and data buses
■ Multiplexed DRAM address bus (NS32FX200 and NS32FV100)
■ Supports 3V freeze mode by maintaining only elapsed time counter
■ Control of power consumption by disabling inactive modules and reducing the clock frequency
■ Operating frequency
