Overview
The APOLLO512-KBR is an ARM Cortex-M4F System on Chip (SoC) from Ambiq Micro's Apollo series. It operates at a maximum frequency of 24 MHz and integrates 512 KB of flash memory with 64 KB of RAM. The device features 27 I/O pins and supports I2C, SPI, and UART/USART interfaces. It includes peripherals such as Brown-out Detect/Reset, Power-On Reset, and Watchdog Timer. Packaged in a 41-WLCSP (2.9x2.49 mm), it functions within a temperature range of -40°C to 85°C.
Feature Summary
- Ultra-low power operation enabled by subthreshold technology
- Integrated floating-point unit for efficient signal processing
- Compact WLCSP packaging suitable for space-constrained designs
Applications
- Wearable devices requiring extended battery life
- Smart home sensors and actuators
- IoT edge nodes with limited power budgets
Procurement Notes
Verify the specific suffix KBR against official datasheets to confirm package type and temperature grade. Confirm component status as Not Recommended for New Designs (NRND) to assess long-term supply viability. Ensure compatibility with existing PCB footprints for the 41-WLCSP form factor before procurement.
Selection Notes
Select this model when minimal active current consumption is critical. Compare memory sizes against application requirements to ensure 512 KB flash suffices. Verify that the 24 MHz clock speed meets real-time processing needs. Check if the 41-pin count aligns with interface requirements.
Part Context
This part belongs to the Apollo family, known for ultra-low power performance. It shares architectural similarities with other Apollo MCUs but offers specific memory and pin configurations. The Apollo series targets applications where energy efficiency is paramount, leveraging Ambiq's SPOT platform technology.
Replacement Considerations
Check for direct substitutes within the Apollo family with similar memory and package constraints. Evaluate newer Apollo generations for improved performance or availability, ensuring pin-to-pin compatibility if required.
