Product details
Overview
CY8C5368AXI-106 from Infineon Technologies (acquired Cypress Semiconductor) is a 32-bit programmable system-on-chip (PSoC® 5) integrating ARM Cortex-M3 MCU, configurable analog/digital peripherals, 256 KB flash, 64 KB SRAM, and USB 2.0 interface in a 100-pin TQFP package. It operates from 2.7–5.5 V, supports 67 MHz CPU clock via internal PLL, and delivers 12-bit SAR ADC at 700 ksps, dual 8-bit DACs at 5.5 Msps, and CapSense® capacitive sensing on any GPIO.
For engineers reviewing the CY8C5368AXI-106 datasheet, CY8C5368AXI-106 pinout, CY8C5368AXI-106 application, or CY8C5368AXI-106 equivalent, key selection criteria include USB 2.0 FS capability, analog subsystem configurability (PGA/TIA/mixer), low-power hibernate mode (300 nA), and PSoC Creator™-based schematic-driven firmware development for mixed-signal embedded systems.
Technical Context
The CY8C5368AXI-106 implements a hierarchical architecture with a 32-bit ARM Cortex-M3 core, 24 universal digital blocks (UDBs) for custom logic synthesis, and a fully routable analog subsystem including two opamps, four comparators, and programmable SC/CT blocks. Its digital interconnect (DSI) enables arbitrary signal routing between peripherals and 60 GPIOs or 8 SIOs.
Analog signal acquisition uses a 12-bit SAR ADC with ±1 LSB INL, 1.024 V ±1% internal reference, and support for up to 62 analog inputs via GPIO routing. Clocking includes a 3–48 MHz IMO, 4–25 MHz crystal oscillator, 32.768 kHz RTC oscillator, and PLL-based 67 MHz system clock - all digitally trimmed for voltage/temperature stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ARM Cortex-M3, 3-stage pipeline, up to 67 MHz - enables real-time deterministic control with NVIC interrupt tail-chaining and low-latency ISR response. |
| Memory | 256 KB flash (100k write cycles, 20-yr retention), 64 KB SRAM, 2 KB EEPROM - supports secure firmware updates, data logging, and bootloader storage without external memory. |
| ADC | 12-bit SAR, 700 ksps, ±1 LSB INL - suitable for precision sensor interfacing (e.g., thermocouples, strain gauges) with minimal external signal conditioning. |
| DAC | Two 8-bit IDACs/VDACs, 5.5 Msps current output or 1 Msps voltage output - enables closed-loop analog actuation (e.g., LED dimming, bias control) directly from GPIO pins. |
| USB Interface | Full-Speed USB 2.0 (12 Mbps), hardware PHY, 24 MHz external crystal required - provides plug-and-play host communication without external transceiver or protocol stack overhead. |
| Power Modes | Hibernate: 300 nA with RAM retention; Sleep: 2 µA; Active: 6 mA @ 6 MHz - enables battery-powered operation for >10-year shelf life in metering or IoT endpoint applications. |

Pinout & Package
Package: 100-pin TQFP (14 mm × 14 mm, 0.5 mm pitch), RoHS-compliant, industrial temperature range (–40°C to +85°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDA / VDDD | Analog/Digital Power Supply | Separate 2.7–5.5 V supplies enable noise isolation between analog and digital domains; decoupling required per datasheet layout guidelines. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable mixed-signal SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F303VCT6 | ARM Cortex-M4F core, 256 KB flash, 48 KB SRAM, but no integrated CapSense® or configurable analog blocks; relies on external opamps/ADCs. | Limited analog configurability; requires additional components for touch or precision sensor interfaces. | Prefer when floating-point math or DSP acceleration is critical, and analog subsystem is implemented externally. |
| MAX32660 | ARM Cortex-M4, 256 KB flash, 96 KB SRAM, ultra-low-power (1.6 µA/MHz), but lacks USB PHY, UDBs, and CapSense® IP - only basic analog peripherals. | No native USB or hardware-accelerated capacitive sensing; limited digital logic flexibility. | Prefer for battery-critical wearables where USB connectivity and analog configurability are secondary to sub-µA sleep current. |
Compared with STM32F303VCT6 and MAX32660, CY8C5368AXI-106 uniquely integrates USB 2.0 PHY, CapSense® engine, and 24 UDBs - enabling single-chip mixed-signal system consolidation where analog front-end flexibility and human interface integration are primary design goals.

FAQ
What development tools are required to program CY8C5368AXI-106?
PSoC Creator™ IDE (v4.4 or later) is mandatory for schematic-based design and component configuration. Programming requires a MiniProg3 or KitProg debugger via SWD interface. USB firmware updates can be performed in-field using the included bootloader with I2C, SPI, UART, or USB interfaces - no external programmer needed after initial provisioning.
Does CY8C5368AXI-106 support hardware encryption for secure boot?
Yes - it includes flash security features such as read protection, write protection, and secure boot with signature verification using SHA-256. The device supports encrypted firmware images stored in flash, with decryption keys managed in protected memory regions. Secure debug access is disabled once flash protection is enabled.
Can the SAR ADC perform simultaneous sampling across multiple channels?
No - the single SAR ADC core supports sequential sampling only, with configurable scan sequences and DMA-triggered transfers. Simultaneous sampling requires external analog multiplexers or discrete ADCs; however, the 700 ksps rate enables effective time-interleaved acquisition across up to 16 channels within 22.9 µs total conversion time.
Is the 100-pin TQFP package lead-free and RoHS compliant?
Yes - CY8C5368AXI-106 is manufactured in a lead-free, halogen-free, RoHS-compliant 100-pin TQFP package (package code "X" per ordering guide), qualified to JEDEC J-STD-020 moisture sensitivity level 3 and rated for industrial temperature operation (–40°C to +85°C).
