Infineon Technologies CY8C6117BZI-F34

Overview

CY8C6117BZI-F34 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 FS device/host interface, and QSPI/XIP support - deployed in IoT edge nodes requiring secure, low-power, sensor-rich operation with real-time responsiveness.

For engineers reviewing the CY8C6117BZI-F34 datasheet, CY8C6117BZI-F34 pinout, CY8C6117BZI-F34 application, or CY8C6117BZI-F34 equivalent, key selection criteria include dual-CPU power efficiency (22 µA/MHz M4 @ 0.9 V), on-chip SIMO DC-DC converter (<1 µA quiescent), Deep Sleep current (7 µA w/64-KB SRAM retention), and hardware crypto acceleration for TLS/OTA updates.

Technical Context

The CY8C6117BZI-F34 implements a tightly coupled dual-CPU architecture where the Cortex®-M4F handles application workloads while the Cortex®-M0+ manages security services, peripheral offload, and boot integrity - both cores share memory-mapped peripherals via a high-bandwidth interconnect. Its clock system integrates an 8-MHz IMO (±2%), 32-kHz ILO, PLL/FLL frequency synthesis, and integer/fractional dividers to drive TCPWM, SCB, and USB timing domains independently.

Power management includes six operational modes, a backup domain with RTC and 64-byte memory, and a SIMO buck converter enabling single-supply 1.7–3.6-V operation. The programmable analog subsystem delivers 12-bit SAR ADC (1-Msps, 16-channel sequencer), two Deep Sleep-capable comparators, and two opamps - all accessible without waking the main CPU.

FAQ

What is the maximum operating frequency of the Cortex-M4F core in CY8C6117BZI-F34?

The Cortex-M4F core operates at up to 150 MHz with single-cycle multiply, floating-point unit, and memory protection unit enabled. This frequency is achievable under 1.1-V core supply with active cooling; at 0.9-V core, max frequency is reduced to maintain power efficiency while delivering 22 µA/MHz active current draw.

Does CY8C6117BZI-F34 support external memory execution (XIP)?

Yes, the device supports Execute-In-Place from external quad SPI flash via its QSPI/SMIF interface, including on-the-fly AES-256 decryption and a dedicated 4-KB cache to reduce power consumption during instruction fetch. XIP operates at up to 640 Mbps in octal mode with hardware address remapping.

How many GPIOs are available, and what advanced I/O features do they support?

CY8C6117BZI-F34 provides up to 100 programmable GPIOs, including six overvoltage-tolerant (OVT) pins and two Smart I/O ports (16 pins total) capable of Boolean logic operations during Deep Sleep. All GPIOs support configurable drive strength, slew rate, and multiple pull-up/down modes - with hardware routing to analog peripherals and CAPSENSE™.

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

Yes, CAPSENSE™ on CY8C6117BZI-F34 delivers industry-leading signal-to-noise ratio (SNR) and supports automatic hardware tuning (SmartSense) for dynamic compensation against water, sweat, or condensation. It enables robust proximity and mutual-capacitance sensing on curved surfaces - validated per IEC 61000-4-6 for conducted immunity in wet environments.
