ADSP-21992 Rev. A is a mixed-signal DSP controller with CAN bus. It has a 16-bit fixed-point DSP core with up to 160 MHz sustained performance, 48K words of on-chip RAM, as 32K words on-chip 24-bit program RAM, and 16K words on-chip, 16-bit data RAM. In addition, the product also has external memory interface, dedicated memory DMA controller, programmable PLL and flexible clock generation circuit, IEEE JTAG Standard 1149.1 test access port, 8-channel 14-bit analog-to-digital converter system, 3-phase 16-bit center based PWM generation unit and dedicated 32-bit encoder interface unit.
The ADSP-21992 is a mixed-signal DSP controller based on the ADSP-2199x DSP core, designed for high-performance industrial motor control and signal processing applications. It integrates a fixed-point DSP core with up to 160 MIPS sustained performance, 48K words of on-chip memory, and a comprehensive set of embedded control peripherals.
Key integrated peripherals include an 8-channel, 14-bit analog-to-digital converter (ADC) system, a 3-phase 16-bit center-based PWM generation unit, a Controller Area Network (CAN) module compliant with V2.0B, and a dedicated encoder interface unit. The device supports flexible clock generation, multiple boot modes, and IEEE JTAG Standard 1149.1 test access for debugging and emulation.
