WM0011ECS/R

Overview

The WM0011ECS/R is a general-purpose low-power audio digital signal processor manufactured by Cirrus Logic (formerly Wolfson Microelectronics). It integrates a 260MHz Tensilica HiFi EP™ 24-bit DSP core with optimized I/O and peripherals for portable consumer electronics. The device features 256kB local RAM, 384kB system RAM, and flexible boot options via 32kB boot ROM. It supports software-defined standby modes to extend battery life in handheld devices. The component is housed in a compact 3x3mm 49-ball W-CSP package with a 0.4mm pitch.

Procurement Notes

Verify the specific revision level against the latest production data sheet before procurement. Confirm that the EOL status or lifecycle stage aligns with long-term availability requirements. Ensure compatibility with existing firmware tools and debugging environments provided by the manufacturer.

Selection Notes

Select this component when a programmable DSP architecture is required for custom audio algorithms rather than fixed-function codecs. Evaluate power consumption profiles against the target application's battery constraints. Verify that the available memory resources are sufficient for the intended third-party audio processing libraries.

Part Context

This part belongs to the Wolfson/Cirrus Logic audio DSP family, designed specifically for high-efficiency audio processing in mobile platforms. It serves as a flexible alternative to dedicated CODECs by allowing software implementation of various audio standards and enhancement features.

Replacement Considerations

No direct public substitute part numbers are documented in the provided source material. Designers should evaluate other Cirrus Logic DSP or CODEC families based on pin compatibility and functional requirements.
