NS32FX164-25 General Description

The NS32FX164, the NS32FV16 and the NS32FX161 are high-performance 32-bit members of the Series 32000É/ 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.

Unless specified otherwise any reference to the NS32FX164 in this document applies to the NS32FV16 and the NS32FX161 as well. The NS32FX164 can perform all the computations and control functions required for a stand-alone Fax system, a PC add-in Fax/Voice/Data Modem card or a Laser/Fax system.

It also meets the performance requirements to implement 14400, 9600 and 7200 bps modems complying with CCITT V.17, V.29 and V.27 standards. The NS32FV16 supports V.29 and V.27 standards as well as voice. The NS32FX161 supports V.29 and V.27 standards.

The NS32FX164 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 (DSPM) and a 4K-byte RAM Array (2K in the NS32FV16 and NS32FX161). The DSPM is a complete processing unit, capable of autonomous operation parallel to the CPU core operation. The DSPM executes programs stored in an internal on-chip Random Access Memory (RAM), and manipulates data stored either in the internal RAM or in an external off-chip memory. To maximize utilization of hardware resources, the DSPM contains a pipelined DSP-oriented datapath, and a control logic that implements a set of DSP vector commands.

The NS32FX164 capabilities can be expanded by using an external floating point unit (FPU) which directly interfaces to the NS32FX164 using the slave protocol. The CPU-FPU cluster features high speed execution of the floating-point instructions.

The NS32FX164 highly-efficient architecture combined with the NS32CG16 graphics instructions and the high-performance vector operation capability, makes the device the ideal choice for PostscriptTM and Fax applications.

NS32FX164-25 Maximum Ratings

Temperature under Bias.... 0 to +70
Storage Temperature.... -65 to +150
All Input or Output Voltages
with Respect to GND..... -0.5V to +6.5V

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