AMAP42KP-KBR

Overview

The AMAP42KP-KBR is an RF System on a Chip (SoC) from the Apollo4 Plus series by Ambiq Micro. It integrates a Cortex-M4F processor running at 192MHz with a 2.5D GPU. The device includes 2MB of MRAM and 2.75MB of SRAM. It operates within a temperature range of -20 to +60°C and is housed in a 146-pin BGA package.

Feature Summary

• Integrates a 192MHz Cortex-M4F core with a 2.5D GPU for high-performance processing
• Combines 2MB MRAM and 2.75MB SRAM for efficient memory management
• Designed as an RF SoC for wireless connectivity applications

Applications

• Wireless communication devices requiring integrated RF and processing capabilities
• IoT endpoints utilizing the Apollo4 Plus architecture
• Embedded systems needing combined MCU and GPU functionality

Procurement Notes

Verify the specific suffix KBR against official Ambiq documentation to confirm pinout, thermal characteristics, and material compliance. Ensure the 146-pin BGA footprint matches your PCB design constraints. Confirm the commercial temperature grade (-20 to +60 C) aligns with your operational environment requirements before finalizing procurement.

Selection Notes

Select this component when a unified solution for RF connectivity and complex signal processing is required. The inclusion of a 2.5D GPU alongside the Cortex-M4F core distinguishes it from standard MCUs. Verify that the 2.75MB SRAM and 2MB MRAM capacities meet your application's data storage and execution needs without external memory interfaces.
