ZL38002QDG1

Overview

The ZL38002QDG1 is a dedicated voice processor manufactured by Microchip Technology, designed for entry-level voice processing applications. It integrates an audio codec and digital signal processing capabilities within a single package. The component operates with a supply voltage of 1.2 V and supports interfaces including GPIO, I2S, SPI, and UART. It is housed in a 48-pin TQFP package and functions within a temperature range of -40°C to +85°C. This device provides hardware-accelerated voice processing features suitable for communication systems requiring low power consumption and compact form factors.

Feature Summary

• Integrated voice processing engine with built-in audio codec functionality
• Supports multiple digital interface protocols for flexible system integration
• Optimized for low-power operation in portable and stationary devices

Applications

• Hands-free speakerphone systems
• VoIP endpoints and gateways
• Intercom and paging systems

Procurement Notes

Verify the specific suffix 'QDG1' against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with existing board layouts regarding the TQFP-48 footprint. Confirm that the 1.2V supply requirement aligns with the target system's power architecture before procurement.

Selection Notes

Select this component when a dedicated voice processor with integrated codec is required for cost-sensitive applications. Compare channel count and interface availability against higher-end models like the ZL38004 series if additional channels are needed. Verify that the TQFP package suits the assembly process and thermal requirements of the final product.

Part Context

This part belongs to the ZL380xx family of voice processors from Microchip Technology. These devices are engineered to offload voice processing tasks from main CPUs, reducing overall system complexity and power consumption. The ZL38002 variant represents an entry-level solution within this portfolio, focusing on essential voice processing features.

Replacement Considerations

Check Microchip's official obsolescence notices for potential end-of-life status. Consider the ZL38004QCG1 or ZL38012LDG1 as alternative options if additional channels or different packaging are acceptable, subject to design re-validation.
