AD21488WBCPZ402

Overview

The AD21488WBCPZ402 is a member of the Analog Devices SHARC family, specifically the ADSP-21488 automotive-grade processor. It features a single-instruction, multiple-data (SIMD) computational architecture optimized for high-performance audio processing. The device operates at a maximum instruction rate of 400 MHz and includes 5 Mbits of on-chip RAM and 4 Mbits of on-chip ROM. It supports 32-bit/40-bit floating-point arithmetic and integrates audio-centric peripherals such as the digital applications interface (DAI), serial ports, S/PDIF transceiver, and asynchronous sample rate converters. The component is housed in an 88-lead LFCSP package.

Feature Summary

• High-performance SIMD core with 32-bit/40-bit floating-point support
• On-chip memory configuration: 5 Mbits RAM and 4 Mbits ROM
• Maximum operating frequency of 400 MHz
• AEC-Q100 qualified for automotive applications

Applications

• Automotive audio processing systems
• High-performance audio decoding algorithms
• Industrial control applications requiring robust DSP capabilities

Procurement Notes

Verify the specific ordering suffix to confirm package type and temperature range. Confirm AEC-Q100 qualification status if automotive compliance is required. Check for any recent revision updates in the datasheet that may affect pin compatibility or electrical specifications.

Selection Notes

Select this model for applications requiring 400 MHz performance with 5 Mbits of internal RAM. Ensure the 88-lead LFCSP package fits the board layout constraints. Verify that the external port interface requirements are met, noting that some packages may have limited external memory controller availability.

Part Context

This part belongs to the fourth-generation SHARC processor family, which includes the ADSP-21483, ADSP-21486, ADSP-21487, ADSP-21488, and ADSP-21489. All members of this family are pin-compatible and source code compatible with previous SHARC processors.

Replacement Considerations

The ADSP-21483, ADSP-21486, ADSP-21487, and ADSP-21489 are pin-compatible within the same package type. However, memory configurations and maximum clock speeds vary between models. Verify specific feature requirements before substitution.
