APOLLO512-KCR

Overview

The APOLLO512-KCR is an ARM Cortex-M4F System-on-Chip manufactured by Ambiq Micro. It operates at a clock speed of 24MHz and integrates 512KB of flash memory with 64KB of RAM. The device features 27 I/O pins and supports I2C, SPI, and UART/USART interfaces. Peripherals include power-on reset, watchdog timer, and brown-out detection. It is housed in a 41-WLCSP package measuring 2.9x2.49mm and functions within a temperature range of -40°C to 85°C.

Feature Summary

• Integrates ARM Cortex-M4F processor core for embedded control
• Includes on-chip flash and SRAM for code and data storage
• Supports standard serial communication protocols including I2C, SPI, and UART

Applications

• Battery-powered IoT sensors
• Wearable devices
• Smart home peripherals

Procurement Notes

Verify component authenticity through authorized channels as the part status is listed as Not Recommended for New Designs. Confirm package integrity upon receipt, noting the 41-WLCSP form factor requires appropriate handling procedures during assembly. Ensure compliance with RoHS3 standards before integration into final products.

Selection Notes

Select this model when low-speed processing suffices and minimal pin count is required. The 24MHz frequency limits complex real-time tasks compared to higher-end Apollo variants. Verify that 512KB flash meets application storage needs without external memory expansion requirements.

Part Context

This component belongs to the Apollo family of ultra-low-power microcontrollers. It utilizes subthreshold power-optimized technology to minimize energy consumption. The device serves as a cost-effective solution for simple embedded applications requiring basic connectivity and moderate processing capabilities.

Replacement Considerations

Check for pin-compatible alternatives within the same Apollo series if supply constraints exist. Verify electrical parameter compatibility, specifically voltage levels and interface speeds, before substituting with other Ambiq Micro SoCs.
