Infineon Technologies CY8C6136FDI-F42T

Overview

CY8C6136FDI-F42T from Infineon is a dual-core PSOC™ 61 microcontroller featuring a 150-MHz Arm® Cortex®-M4F CPU and a dedicated 100-MHz Cortex®-M0+ for system control, 1-MB flash, 288-KB SRAM, integrated CAPSENSE™, USB Full-Speed device/host interface, and QSPI/XIP support - deployed in industrial IoT edge nodes requiring secure, low-power sensor fusion and local decision-making.

For engineers reviewing the CY8C6136FDI-F42T datasheet, CY8C6136FDI-F42T pinout, CY8C6136FDI-F42T application, or CY8C6136FDI-F42T equivalent, key selection criteria include dual-CPU power efficiency (22 µA/MHz @ 0.9 V M4), on-chip SIMO DC-DC converter (<1 µA quiescent), Deep Sleep current (7 µA with 64-KB SRAM retention), and hardware cryptographic acceleration for TLS/OTA updates.

Technical Context

The CY8C6136FDI-F42T implements a tightly coupled dual-CPU architecture where the Cortex®-M4F handles application workloads (including floating-point math and DSP) while the Cortex®-M0+ manages real-time system services, security boot, and peripheral arbitration - with IPC and shared memory enabling deterministic inter-core communication. Its clock system integrates FLL, PLL, IMO (±2%), ILO (32 kHz), and crystal oscillators (16–35 MHz), supporting dynamic voltage/frequency scaling across six power modes.

Analog subsystem includes a 12-bit 1-Msps SAR ADC with 16-channel sequencer and result averaging, two deep-sleep-capable comparators, a 12-bit DAC (<2 µs settling), and two opamps with low-power modes. Programmable digital resources comprise twelve UDBs (8 macrocells each), Smart I/O blocks for Boolean logic during Deep Sleep, and 32 TCPWM blocks supporting center-aligned PWM and comparator-triggered kill signals.

FAQ

What is the core voltage configuration for CY8C6136FDI-F42T?

This device operates its Cortex-M4F and Cortex-M0+ cores at either 0.9 V or 1.1 V, selected at manufacturing based on speed/power trade-off. The 0.9-V option delivers 22 µA/MHz (M4) and 15 µA/MHz (M0+) active current, while 1.1 V yields 40 µA/MHz and 20 µA/MHz - both configurations maintain full 150/100 MHz operation and are fixed per part number.

Does CY8C6136FDI-F42T support execute-in-place (XIP) from external flash?

Yes - its QSPI/SMIF interface supports XIP from external quad/octal SPI flash with on-the-fly AES-128 decryption and a dedicated 4-KB cache. This enables direct code execution from external memory while maintaining low power, eliminating need for large internal flash and simplifying firmware updates via external memory partitioning.

How many GPIOs support capacitive sensing on this device?

All 100 GPIOs are CAPSENSE™-capable, with hardware support for self-capacitance (up to 99 segments) and mutual-capacitance (up to 8 commons). The subsystem includes SmartSense auto-tuning, noise immunity algorithms, and dedicated hardware counters - enabling robust touch, proximity, and liquid-tolerant interfaces without CPU intervention.

Is USB functionality limited to device mode or does it support host operation?

CY8C6136FDI-F42T integrates a full-speed USB 2.0 PHY and controller supporting both device and host roles - including CDC, HID, MSC, and custom class implementations. It provides dedicated USB VBUS detection, internal transceivers, and DMA-accelerated transfers, enabling dual-role applications like USB-C dongles or field-programmable gateways.
