Infineon Technologies CY8C6247FDI-D02T

Overview

CY8C6247FDI-D02T 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 cryptography accelerator-designed for secure, ultra-low-power IoT edge nodes requiring concurrent real-time control and wireless connectivity.

For engineers reviewing the CY8C6247FDI-D02T datasheet, CY8C6247FDI-D02T pinout, CY8C6247FDI-D02T application, or CY8C6247FDI-D02T 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 CY8C6247FDI-D02T implements a tightly coupled dual-CPU architecture where the Cortex-M4F handles compute-intensive tasks (e.g., signal processing, TLS stack) while the Cortex-M0+ manages low-latency peripherals and power state coordination via IPC and shared memory. Both cores operate at independent voltages (0.9 V or 1.1 V) and support fine-grained power gating.

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

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency of the Cortex-M4F core in CY8C6247FDI-D02T?

The Cortex-M4F core operates at up to 150 MHz, confirmed in the official Infineon datasheet (Rev. *Q, p.1). This frequency is achievable under 1.1-V core supply and ambient temperatures ≤85°C. At 0.9-V operation, maximum frequency is reduced to maintain timing closure and power integrity-details are specified in the "Device-Level Specifications" section (p.53).

Does CY8C6247FDI-D02T support external quad SPI flash with execute-in-place (XIP)?

Yes, the device supports XIP from external quad SPI flash via its Serial Memory Interface (SMIF), with hardware-accelerated on-the-fly AES-128 decryption. The SMIF includes a 4-KB cache to reduce latency and power consumption during instruction fetch. Supported interfaces include single, dual, quad, dual-quad, and octal modes, with throughput up to 640 Mbps in octal mode.

How many GPIO pins support Smart I/O functionality in Deep Sleep mode?

16 GPIO pins-organized as two Smart I/O ports (P0[0]–P0[7] and P12[0]–P12[7])-retain Boolean logic capability (AND, OR, XOR, invert) during Deep Sleep. These pins can process input combinations and trigger wake events without CPU intervention, reducing average system current in sensor-monitoring applications.

Is the CAPSENSE™ subsystem on CY8C6247FDI-D02T compatible with wet or gloved touch?

Yes, CAPSENSE™ supports liquid-tolerant and gloved-finger operation through hardware-based shield electrode drive and automatic SmartSense tuning. The subsystem achieves >100:1 signal-to-noise ratio and dynamically adjusts scan parameters (frequency, resolution, averaging) to maintain reliability in presence of water films or thick gloves-validated per IEC 61000-4-6 and IP67 test conditions.
