AMA4B2KP-KBR

Overview

The AMA4B2KP-KBR is an RF System on a Chip (SoC) from Ambiq Micro, Inc., belonging to the Apollo4 Blue Lite series. It integrates an ARM Cortex-M4F core operating at frequencies up to 192 MHz with a 2.5D GPU. The device features 2 MB of MRAM and 1.4 MB of SRAM. It supports Bluetooth Low Energy 5.4 connectivity. The component is housed in a 131-pin BGA package and operates within a temperature range of -20°C to +60°C.

Feature Summary

• Integrates a 2.5D GPU alongside the ARM Cortex-M4F processor for enhanced graphical processing capabilities.
• Supports Bluetooth Low Energy 5.4 wireless communication protocols.
• Combines non-volatile MRAM with substantial SRAM for efficient data handling.

Applications

• Bluetooth-enabled wearable devices requiring low power consumption.
• Smart home IoT sensors utilizing BLE 5.4 connectivity.
• Audio applications leveraging integrated graphics and audio processing.

Procurement Notes

Verify the specific suffix KXR against the requested model when sourcing, as distributor listings may vary by packaging or regional designation. Confirm RoHS compliance status and moisture sensitivity levels prior to assembly planning. Ensure the supplier provides official datasheets matching the exact part number to avoid integration errors during hardware design.

Selection Notes

Select this SoC for designs requiring integrated graphics acceleration and BLE 5.4 support in a compact form factor. Compare memory configurations against the standard Apollo4 Blue variants if higher SRAM capacity is needed. Evaluate the 131-pin BGA package constraints against PCB layout capabilities and thermal management requirements for the target application environment.

Part Context

This component is part of the Apollo4 Blue Lite family, designed for cost-sensitive yet feature-rich embedded applications. It shares architectural similarities with other Ambiq microcontrollers but distinguishes itself through the inclusion of a dedicated 2.5D GPU and updated Bluetooth standards. The series targets consumer electronics and industrial IoT sectors.
