Description
General part information
ADSP-21991 Series
The ADSP-21991 extends the ADSP-2199x mixed signal DSP product family by offering increased memory integration compared with the ADSP-21990. The ADSP-21991 integrates a 160 MHz, 16-bit, ADSP-219x DSP core and an 8-channel, 14-bit, 20 MSPS ADC (with dual sample-and-hold amplifiers for simultaneous sampling). Additional mixed-signal integration includes a precision on-chip voltage reference, and a power-on-reset (POR) circuit. Various control peripherals are provided for single-chip solutions for embedded control and signal processing applications.
