NOTE:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.
DescriptionThe IDT7216 is a high-speed, low-power 16 x 16-bit multiplier, ideal for fast, real time digital signal processing applications. Utilization of a modified Booths algorithm and IDT's high-performance, submicron CMOS technology, has achieved speeds comparable to bipolar (20ns max.), at 1/ 10 the power consumption.
The IDT7216 is ideal for applications requiring high-speed multiplication such as fast Fourier transform analysis, digital filtering, graphic display systems, speech synthesis and recognition and in any system requirement where multiplication speeds of a mini/microcomputer are inadequate.
All input registers, as well as LSP and MSP output registers, use the same positive edge-triggered D-type flip-flop. In the IDT7216, there are independent clocks (CLKX, CLKY, CLKM, CLKL) associated with each of these registers.
The IDT7216 offers additional flexibility with the FA control andMSPSEL functions.
The FA control formats the output for two's complement by shifting the MSP up one bit and then repeating the sign bit in the MSB of the LSP. The MSPSEL low selects the MSP to be available at the product output port, while a high selects the LSP to be available. Keeping this pin low will ensure compatibility with the TRW MPY016H.
