AMA4B2KL-KXR

Overview

The AMA4B2KL-KXR is an RF System on a Chip (SoC) from the Apollo4 Blue Lite series by Ambiq Micro. It integrates an ARM Cortex-M4F processor running at 192MHz with a 2.5D GPU. The device includes 2MB of MRAM and 1.4MB of SRAM. It supports Bluetooth Low Energy 5.4 connectivity. The component operates within a temperature range of -20°C to +60°C. It is housed in a 131-pin BGA package.

Feature Summary

• Integrates a 2.5D GPU alongside the Cortex-M4F core for enhanced processing capabilities.
• Features ultra-low power sub-threshold analog design technology for extended battery life.
• Supports BLE 5.4 protocol for modern wireless communication standards.

Applications

• Wearable health monitoring devices
• Smart home sensors and actuators
• Industrial IoT gateways

Procurement Notes

Verify the specific suffix KXR against official datasheets to confirm package type and temperature grade. Ensure compatibility with the Apollo4 Blue Lite SDK for software development. Check RoHS compliance status through manufacturer documentation before integration into regulated products.

Selection Notes

Select this SoC when high-performance graphics acceleration is required in a low-power wearable form factor. Compare memory sizes against other Apollo4 variants if larger storage is needed. Verify pinout compatibility with existing PCB layouts due to the 131-pin BGA configuration.

Part Context

This part belongs to the Apollo4 Blue Lite family, designed specifically for cost-sensitive and power-constrained applications. It shares architectural similarities with the broader Apollo4 series but offers optimized memory configurations for specific market segments requiring efficient BLE connectivity.

Replacement Considerations

Direct substitutes may include other Apollo4 Blue Lite variants with different memory sizes or package options. Consult the Apollo-SoC-Selector-Guide for cross-referencing compatible components within the same product line.
