Note: Absolute maximum ratings indicate limits beyond which permanent damage may occur. Continuous operationat these limits is not intended; operation should be limited to those conditions specified under Electrical Characteristics.

The NS32FX16 is a high-performance 32-bit member of the Series 32000/EPTM family of National's Embedded System ProcessorsTM specifically optimized for CCITT Group 2 and Group 3 Facsimile Applications, Data Modems, Voice Mail Systems, Laser Printers, or any combination of the above.

NS32FX16 can perform all the computations and control functions required for a stand-alone Fax system, a PC add-in Fax/ Data Modem card or a Laser/Fax system.

NS32FX16 also meets the performance requirements to implement 9600 and 7200 bps modems complying with CCITT V.29 and V.27 standards.

The NS32FX16 provides a 16 Mbyte Linear external address space and a 16-bit external data bus. The CPU core, which is the same as that of the NS32CG16, incorporates a 32-bit ALU and instruction pipeline, and an 8-byte prefetch queue.

 Also integrated on-chip with the CPU are a DSP Module and a 384-byte RAM Array. The DSP Module executes vector operations on complex variables and is specially designed to enhance performance in modem applications. The vector operations can also be used to efficiently implement FIR Filters and other DSP primitives. The on-chip RAM Array is used to store the coefficients of the various filters and can be accessed by both the CPU and the DSP Module.

The NS32FX16 capabilities can be expanded by using an external floating point unit (FPU) which directly interfaces to the NS32FX16 using the slave protocol. The CPU-FPU cluster features high speed execution of the floating-point instructions.
