Analog Devices Inc. ADSP-21992 Mixed-Signal DSP Controller

Analog Devices ADSP-21992 Mixed-Signal DSP Controller offers an ADSP-2199x DSP core, excellent for various high-performance industrial motor control and signal processing applications. These ideal applications require combining a high-performance DSP and the mixed-signal integration of embedded control peripherals, such as analog-to-digital conversion, with communications interfaces such as CAN.

The ADI ADSP-21992 further expands the capabilities of the ADSP-2199x mixed-signal DSP family by offering 32K words of program memory and 16K words of data memory RAM. Additionally, the ADSP-21992 provides an on-chip CAN communications port that provides full CAN 2.0B support, with 16 configurable mailboxes and individual acceptance filters.
