EOS3FLF512-PDN64

Overview

The QuickLogic EOS3FLF512-PDN64 is a system-on-chip (SoC) microcontroller based on the EOS S3 family. It integrates an ARM Cortex-M4F processor, an embedded FPGA (eFPGA), and a dedicated Sensor Processing Engine (SPE). The device features 512 kB of program memory, designed for edge AI and always-on sensing applications. Its heterogeneous architecture enables low-power signal processing and event-driven operation, supporting complex sensor fusion tasks with minimal energy consumption.

Feature Summary

• Heterogeneous architecture combining ARM Cortex-M4F, eFPGA, and SPE
• 512 kB program memory capacity
• Optimized for always-on sensing and edge AI inference
• Zero-copy data path to reduce CPU intervention

Applications

• Wearable health monitoring devices
• Voice wake-word detection systems
• Smart home sensor hubs
• Industrial vibration analysis nodes

Part Context

This component belongs to the QuickLogic EOS S3 series, which targets ultra-low power edge computing. The EOS3FLF512 variant specifically provides 512 kB of flash memory, distinguishing it from lower-capacity siblings in the same package family. It is engineered for scenarios requiring continuous sensor monitoring without frequent wake-ups.

Replacement Considerations

Direct pin-to-pin replacements within the EOS S3 family depend on memory size requirements. Verify if alternative part numbers such as those with different suffixes offer compatible pinouts while meeting the 512 kB memory constraint.
