Infineon Technologies CY8C6247FDI-D52T

Overview

CY8C6247FDI-D52T from Infineon is a dual-core Arm® Cortex®-M4F/M0+ PSoC™ 62 microcontroller with 1-MB flash, 288-KB SRAM, integrated SIMO DC-DC converter, CAPSENSE™, and hardware crypto accelerator-designed for secure, ultra-low-power IoT edge nodes requiring concurrent real-time control and wireless protocol stack execution.

For engineers reviewing the CY8C6247FDI-D52T datasheet, CY8C6247FDI-D52T pinout, CY8C6247FDI-D52T application, or CY8C6247FDI-D52T equivalent, key selection criteria include dual-CPU power efficiency (22 µA/MHz @ 0.9 V M4), QSPI XIP with on-the-fly encryption, Deep Sleep current (7 µA w/ 64-KB SRAM retention), and programmable analog/digital subsystems for sensor fusion and human interface.

Technical Context

The device integrates two tightly coupled Arm cores: a 150-MHz Cortex-M4F with FPU and MPU for application processing, and a 100-MHz Cortex-M0+ for real-time control and low-power background tasks. Inter-processor communication (IPC) and shared memory enable deterministic task partitioning between security-critical and latency-sensitive workloads.

Its programmable analog subsystem includes a 12-bit 1-Msps SAR ADC with 16-channel sequencer and result averaging, two low-power comparators active in Deep Sleep, and a 12-bit DAC with <2-µs settling time-enabling simultaneous sensor acquisition, threshold monitoring, and analog output generation without CPU intervention.

FAQ

What is the maximum operating frequency of the Cortex-M4F core in CY8C6247FDI-D52T?

The Cortex-M4F core operates at up to 150 MHz, confirmed in the Infineon datasheet Rev. *Q Section 3.1.1. This frequency is achievable under 1.1-V core supply with appropriate thermal management. At 0.9-V core voltage, maximum frequency is reduced to maintain timing closure and power efficiency, though exact derated value depends on process corner and temperature.

Does CY8C6247FDI-D52T support execute-in-place (XIP) from external QSPI flash?

Yes, it supports XIP via the Serial Memory Interface (SMIF) with hardware on-the-fly AES-256 decryption and a dedicated 4-KB cache. The QSPI interface supports single/dual/quad/octal modes with throughput up to 640 Mbps, and XIP operation is fully compatible with Deep Sleep retention modes per datasheet Section 3.6.4.

How many GPIOs are available, and what advanced I/O features does it offer?

CY8C6247FDI-D52T provides up to 100 programmable GPIOs, including six overvoltage-tolerant (OVT) pins and two Smart I/O ports (16 pins total) that perform Boolean logic in Deep Sleep. Each GPIO supports configurable drive strength, slew rate, and 12+ programmable drive modes-including open-drain, high-Z analog, and resistive pull-up/down-validated in datasheet Section 3.7.

Is the CAPSENSE™ subsystem capable of liquid-tolerant operation?

Yes, CAPSENSE™ supports liquid tolerance through hardware-based shield electrode scanning and automatic recalibration via SmartSense. The subsystem achieves >100:1 signal-to-noise ratio and maintains reliable touch detection under water droplets or condensation, as verified in Infineon's CAPSENSE™ Design Guide (AN92239) and confirmed in datasheet Section 3.8.2.
