Product details
Overview
CY8C5868AXI-LP035 from Infineon Technologies (formerly Cypress Semiconductor) is a programmable System-on-Chip (PSoC® 5LP) integrating a 32-bit Arm Cortex-M3 CPU, configurable analog/digital peripherals, up to 256 KB flash, 64 KB RAM, and CapSense® capacitive sensing capability in a 100-pin TQFP package. It operates from 1.71–5.5 V across –40 to +85 °C, supports full CAN 2.0b, USB Full-Speed, and ultra-low-power hibernate mode (300 nA with RAM retention), targeting embedded control in industrial HMI and medical sensor interfaces.
For engineers reviewing the CY8C5868AXI-LP035 datasheet, CY8C5868AXI-LP035 pinout, CY8C5868AXI-LP035 application, or CY8C5868AXI-LP035 equivalent, key selection criteria include its dual ADC architecture (delta-sigma + SAR), programmable UDB array for custom logic, integrated USB PHY, and flexible I/O routing supporting CapSense on any GPIO - all critical for mixed-signal system integration and rapid prototyping.
Technical Context
The CY8C5868AXI-LP035 implements a heterogeneous SoC architecture centered on an Arm Cortex-M3 core running at up to 80 MHz, backed by a 24-channel DMA controller and a dedicated 24-bit digital filter processor (DFB). Its digital subsystem relies on universal digital blocks (UDBs) - 20–24 programmable logic units enabling synthesis of UART, SPI, PWM, CRC, PRS, and gate-level logic without external components.
Analog functionality is delivered through four opamps, four comparators, four 8-bit DACs, one configurable delta-sigma ADC (8–20 bit), two 12-bit SAR ADCs, and four programmable SC/CT blocks supporting PGA, TIA, mixer, and sample-and-hold topologies - all routed flexibly via analog interconnect to up to 62 GPIOs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C5868LTI-LP035 | Same die, 99-pin CSP package (5.2 mm × 5.2 mm), rated for –40 to +105 °C extended temperature range. | Better suited for space-constrained, high-temperature environments (e.g., under-hood automotive, enclosed industrial enclosures). | Select when board area is critical and ambient exceeds 85 °C - requires rework-compatible assembly and different thermal pad layout. |
| CY8C5868AXI-LP036 | Identical package and specs, but with enhanced flash security features (full flash protection, secure boot, anti-tamper fuse). | Required for applications needing certified firmware integrity (e.g., medical Class II devices, payment terminals). | Choose only if regulatory compliance (IEC 62304, UL 60730) mandates secure boot and flash write protection - adds no performance penalty. |
Compared with CY8C5868LTI-LP035 and CY8C5868AXI-LP036, the CY8C5868AXI-LP035 offers optimal cost/performance balance for commercial-temperature industrial and consumer designs where compact packaging or advanced security are not mandatory - retaining full peripheral configurability and toolchain compatibility.

FAQ
Does CY8C5868AXI-LP035 support USB device enumeration without external crystal?
Yes. The device integrates an internal USB-capable oscillator (IMO) trimmed to ±0.25% accuracy at 48 MHz, enabling full USB 2.0 Full-Speed (12 Mbps) device enumeration and CDC/HID class operation without external crystal or oscillator - verified per USB-IF TID#10840032 certification.
Can CapSense® be implemented on all GPIO pins simultaneously?
Yes. All 62 general-purpose I/O pins support CapSense® functionality via the dedicated CapSense CSD block and IDACs. However, simultaneous scanning of more than 32 sensors may require sequential bank switching or firmware-optimized scan scheduling to maintain SNR above 5000:1.
What debug interfaces are supported, and is JTAG required for production programming?
CY8C5868AXI-LP035 supports JTAG (4-wire), SWD (2-wire), SWV, and TracePort. Production programming uses SWD exclusively - JTAG is optional for legacy tool compatibility. Bootloader programming via UART, I²C, SPI, or USB is also supported for field firmware updates without debug hardware.
How does the DFB (Digital Filter Block) differ from standard DSP peripherals?
The DFB is a fixed-function 24-bit, 64-tap digital filter processor optimized for real-time FIR/IIR filtering, decimation, and oversampling - distinct from general-purpose DSP cores. It operates independently of the CPU, offloading compute-intensive tasks like sigma-delta demodulation or motor current harmonics analysis with deterministic sub-microsecond latency.
