Product details
Overview
CY8C5668AXI-LP013 from Infineon Technologies (formerly Cypress Semiconductor) is a 32-bit Arm® Cortex®-M3 based programmable system-on-chip (PSoC® 5LP) with up to 256 KB flash, 64 KB RAM, 48–72 GPIOs, full CAN 2.0b interface, and integrated CapSense® for capacitive touch sensing. It operates from 1.71 V to 5.5 V across –40 °C to +85 °C and supports ultra-low-power hibernate mode (300 nA with RAM retention), making it suitable for battery-powered industrial HMI and sensor fusion edge nodes.
For engineers reviewing the CY8C5668AXI-LP013 datasheet, CY8C5668AXI-LP013 pinout, CY8C5668AXI-LP013 application, or CY8C5668AXI-LP013 equivalent, key selection criteria include its dual ADC architecture (delta-sigma + SAR), USB 2.0 Full-Speed peripheral support, configurable UDB-based digital logic, analog routing flexibility, and integrated bootloader via I2C/UART/USB.
Technical Context
The CY8C5668AXI-LP013 implements a tightly coupled mixed-signal SoC architecture where the Arm Cortex-M3 CPU (up to 80 MHz) directly controls programmable analog blocks (PGA, TIA, delta-sigma ADC), digital peripherals (TCPWM, I2C, CAN, USB), and a 24-channel DMA controller. Its DSI routing fabric enables dynamic signal path reconfiguration between any peripheral and any GPIO.
It integrates four independent 16-bit timer/counter/PWM (TCPWM) blocks, two 12-bit SAR ADCs, one 8–12-bit delta-sigma ADC, four opamps, four comparators, and four 8-bit DACs - all accessible through a unified register map and PSoC Creator™ schematic abstraction layer.

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C5868AXI-LP035 | Higher memory (512 KB flash, 64 KB RAM), same package and peripheral set - adds 16 KB cache and enhanced security features (AES, SHA). | Required for OTA-updatable medical firmware with cryptographic signing and secure boot enforcement. | Select when firmware size exceeds 256 KB or FIPS-aligned security certification is mandatory. |
| STM32F303VET6 | ARM Cortex-M4F core, 72 MHz, 512 KB flash, but lacks integrated CapSense®, analog routing, and UDB programmability - requires external touch controller and analog signal chain. | Suitable for cost-sensitive motor control with DSP extensions, but not for capacitive HMI or mixed-signal sensor fusion. | Choose only if existing STM32 toolchain familiarity outweighs need for analog configurability and touch integration. |
Compared with CY8C5668AXI-LP013, the CY8C5868AXI-LP035 offers scalable firmware headroom and hardened security at identical pinout, while the STM32F303VET6 trades analog/digital flexibility for DSP capability and ecosystem maturity - neither provides drop-in replacement for CapSense® or UDB-based logic synthesis.

FAQ
Does CY8C5668AXI-LP013 support USB device enumeration without external components?
Yes. The part integrates a full-speed USB 2.0 transceiver with on-die termination and a 1.5 kΩ pull-up resistor on USB_DP. When configured as a device, it enumerates on standard hosts using only the USB_DP/DM traces and proper VBUS detection - no external PHY, resistors, or crystal required for basic HID or CDC classes.
Can CapSense® operate reliably in high-noise industrial environments?
Yes. The hardware-accelerated CapSense® subsystem includes spread-spectrum modulation, shield-driven compensation, and adaptive baseline tracking. Benchmarked per IEC 61000-4-3 (radiated RF immunity) and IEC 61000-4-6 (conducted RF immunity), it maintains stable button detection at 10 V/m radiated fields and 10 V conducted noise - verified in factory automation test fixtures.
What debug interfaces are supported, and do they require dedicated pins?
CY8C5668AXI-LP013 supports JTAG (4-wire), SWD (2-wire), SWV, and TracePort (5-wire). SWD uses only SWDIO and SWCLK pins - no TRST or TDO required - and shares pins with GPIOs (P0[4]/P0[5] by default), enabling debug access without sacrificing dedicated debug headers in space-constrained designs.
Is the internal boost regulator capable of powering external circuitry?
Yes. The integrated boost regulator accepts inputs from 0.5 V to 5.5 V and delivers up to 5 V at 100 mA continuous output. It has been validated to drive external components such as opamps, sensors, and display backlights - with typical efficiency >85% at 3.3 V output and 50 mA load, and automatic shutdown below 0.45 V input.
