The ADSP-217x is a DSP microcomputer that combines the ADSP-2100 base architecture with new instructions for increased flexibility. It features two serial ports, a host interface port, a programmable timer, extensive interrupt capabilities, and on-chip program and data memory. The ADSP-217x also supports bit manipulations, new ALU constants, a new multiplication instruction, biased rounding, and global interrupt masking. It includes a Bus Grant Hang Logic (BGH) feature and is suitable for battery-operated portable equipment.
The ADSP-2171, ADSP-2172, and ADSP-2173 are single-chip microcomputers optimized for digital signal processing (DSP) and other high-speed numeric processing applications. The ADSP-2171 and ADSP-2172 are designed for 5.0 V applications, while the ADSP-2173 is designed for 3.3 V applications. The ADSP-2172 also includes 8K words of program ROM.
