AMA3B1KK-KCR-TB

Overview

The AMA3B1KK-KCR-TB is an Ambiq Micro Apollo3 Blue System-on-Chip (SoC) featuring an ARM Cortex-M4F processor core operating at a maximum frequency of 96MHz. It integrates 1MB of flash memory and 384KB of RAM within a 66-WLCSP package measuring 3.38x3.25mm. The device supports I2C, SPI, and UART/USART interfaces and includes peripherals such as AES, DMA, I2S, power-on reset, PWM, and watchdog timers. It operates within a temperature range of -40°C to 85°C.

Feature Summary

Ultra-low power operation based on patented SPOT technology
Integrated BLE connectivity with on-board antenna support
Comprehensive peripheral set including audio and security modules

Applications

Battery-powered sensor measurement systems
Wearable health monitoring devices
Bluetooth Low Energy IoT nodes

Procurement Notes

Verify the specific tape-and-reel packaging configuration for the KCR suffix against official Ambiq documentation before ordering. Confirm that the MSL rating and reflow profile requirements align with your assembly line capabilities. Ensure the component status remains active for new designs by checking current manufacturer announcements.

Selection Notes

Select this part when a compact form factor is required alongside significant onboard memory for complex firmware. The 66-pin WLCSP offers a small footprint suitable for space-constrained wearable applications. Compare against the AMA3B1KK-KBR variant if BGA packaging or different thermal characteristics are preferred for the target design.

Part Context

This SoC belongs to the Apollo3 Blue family, designed for ultra-low power wireless applications. It serves as the central processing unit for evaluation boards like the AMA3BEVB, providing the necessary computational resources and radio interface for developing Bluetooth-enabled embedded systems.

Replacement Considerations

The AMA3B1KK-KCR-B0 is a documented related product within the same Apollo3 Blue series. Verify pin compatibility and software library support before substituting between these specific package variants.
