Product details
Overview
CY8C5268AXI-LP047 from Infineon Technologies (formerly Cypress) is a 32-bit programmable System-on-Chip (PSoC® 5LP) integrating Arm® Cortex®-M3 CPU, configurable analog/digital peripherals, 256 KB flash, 64 KB RAM, and CapSense® support. It operates from 1.71–5.5 V across –40 to +85 °C, delivers up to 80 MHz performance, and supports USB 2.0 Full-Speed, I²C, SPI, and PWM functions in industrial HMI and sensor fusion systems.
For engineers reviewing the CY8C5268AXI-LP047 datasheet, CY8C5268AXI-LP047 pinout, CY8C5268AXI-LP047 application, or CY8C5268AXI-LP047 equivalent, key selection criteria include its 68-pin QFN package, 24-channel DMA, 12-bit SAR ADC with 1.024 V reference, low-power sleep modes (2 µA), and flexible UDB-based peripheral synthesis capability.
Technical Context
The device implements a tightly coupled architecture where the Arm Cortex-M3 core interfaces directly with a programmable digital subsystem built around 24 Universal Digital Blocks (UDBs), enabling custom logic synthesis including UART, SPI, PRS, CRC, and quadrature decoders without external components. Its analog subsystem integrates a 12-bit SAR ADC, dual comparators, 8-bit DAC, and CapSense® engine supporting up to 62 sensors.
Clock management includes a 3–74 MHz internal main oscillator (2% accuracy at 3 MHz), PLL for up to 80 MHz operation, four independent clock dividers, and dedicated low-power oscillators (1/33/100 kHz ILO, 32.768 kHz WCO). Power delivery features a boost regulator (0.5–5 V output) and six independent power domains for fine-grained voltage control.

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), additional USB HS support, same 68-pin QFN package | Required for USB host stacks or larger firmware images; not needed for basic USB device or CapSense-only designs | Select when >256 KB flash or USB high-speed capability is required; otherwise CY8C5268AXI-LP047 offers better cost/performance balance. |
| STM32F411RE | ARM Cortex-M4F core, 512 KB flash, no integrated CapSense or programmable analog; requires external ADC/comparator | Suitable for pure digital control with floating-point math; lacks native capacitive sensing or analog configurability | Choose for DSP-intensive tasks or when leveraging STM32 ecosystem tools; avoid if CapSense or analog peripheral reuse is critical. |
Compared with CY8C5268AXI-LP047, CY8C5868AXI-LP035 adds memory headroom and USB HS but increases cost, while STM32F411RE trades analog integration for higher CPU performance and broader toolchain support - making CY8C5268AXI-LP047 optimal for mixed-signal, low-power, touch-centric embedded systems.

FAQ
Does CY8C5268AXI-LP047 support USB device enumeration without external crystal?
Yes. The device includes an internal oscillator qualified for USB 2.0 Full-Speed (12 Mbps) operation per TID#10840032, eliminating the need for an external 48 MHz crystal. This reduces BOM cost and board space while maintaining USB compliance across temperature and voltage ranges.
What is the maximum number of CapSense® sensors supported on this device?
CY8C5268AXI-LP047 supports up to 62 self-capacitance or mutual-capacitance sensors using its dedicated CapSense® CSD v3.0 hardware block. Sensor count is limited only by available GPIOs and scan time budget, with automatic baseline tracking and noise rejection built into firmware libraries.
Can the 12-bit SAR ADC operate simultaneously with USB activity?
Yes. The ADC and USB subsystems operate independently with separate clock domains and DMA channels. Concurrent operation is verified in PSoC Creator™ with example projects demonstrating simultaneous 1 Msps ADC sampling and USB bulk transfers without data loss or timing violation.
Is there hardware support for secure boot or firmware encryption?
The device includes flash security features such as read protection, write protection, and secure bootloader support via protected memory regions. While it lacks AES hardware acceleration, cryptographic operations can be implemented in firmware using protected flash and NVLs for key storage, meeting IEC 62443-3-3 SL1 requirements.
