Product details
Overview
CY8C5867LTI-LP025 from Infineon Technologies (formerly Cypress) is a 32-bit Arm Cortex-M3-based programmable system-on-chip (PSoC® 5LP) integrating configurable analog/digital peripherals, 256 KB flash, 64 KB RAM, and full-speed USB 2.0 interface. It operates from 1.71–5.5 V across –40 to +85 °C, supports CAN 2.0b, CapSense®, and ultra-low-power hibernate mode (300 nA with RAM retention), targeting embedded control in industrial HMI and medical sensor systems.
For engineers reviewing the CY8C5867LTI-LP025 datasheet, CY8C5867LTI-LP025 pinout, CY8C5867LTI-LP025 application, or CY8C5867LTI-LP025 equivalent, key selection criteria include its 80-MHz CPU performance, dual ADC architecture (delta-sigma + SAR), programmable UDB array for custom logic, and routing flexibility enabling analog/digital peripheral assignment to any GPIO - critical for mixed-signal consolidation and rapid prototyping.
Technical Context
The device implements a tightly coupled subsystem architecture: Arm Cortex-M3 core with 24-channel DMA and 24-bit DFB co-processor handles real-time signal processing, while independent analog and digital routing matrices allow concurrent configuration of up to 100 peripherals without fixed-function constraints. Clocking includes PLL (up to 80 MHz), IMO (1–74 MHz), and low-power oscillators (1/33/100 kHz).
Analog resources comprise four opamps, four comparators, four 8-bit DACs, configurable delta-sigma ADC (8–20 bit), two 12-bit SAR ADCs, and programmable SC/CT blocks supporting PGA, TIA, and mixer functions. Digital subsystem leverages 20–24 universal digital blocks (UDBs) for synthesizing UART, SPI, LIN, CRC, quadrature decoders, and gate-level logic.

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C5868LTI-LP023 | Same die, 100-pin TQFP package, higher I/O count (72 GPIO), no USBIO pins | Better suited for designs requiring >62 GPIOs and no USB device functionality | Select when board layout accommodates larger footprint and USB is not required. |
| CY8C5888LTI-LP097 | Extended temperature grade (–40 to +105 °C), same 68-pin QFN package | Required for under-hood automotive or industrial ambient above 85 °C | Choose for thermal environments exceeding standard grade limits; otherwise identical functionality. |
Compared with CY8C5867LTI-LP025, the LP023 offers more I/O but lacks USB PHY support, while the LP097 maintains identical features with extended thermal qualification - making the LP025 optimal for cost-sensitive, USB-reliant, and standard-temperature industrial HMI designs.

FAQ
What development tools are required to program CY8C5867LTI-LP025?
PSoC Creator™ IDE (free download from Infineon) is the primary tool, supporting schematic-based hardware design, C firmware development, and drag-and-drop component integration. Programming requires MiniProg3, KitProg, or onboard SWD interface - no external programmer needed for evaluation kits like CY8CKIT-059.
Does CY8C5867LTI-LP025 support secure boot or firmware encryption?
Yes - it includes flash security features such as read protection, write protection, and secure bootloader with authentication keys. The device supports AES-128 encryption for firmware images and can enforce signature verification before execution using protected nonvolatile latches.
Can the delta-sigma ADC operate simultaneously with the SAR ADCs?
Yes - both ADC subsystems are independent and share no clock or resource conflicts. The delta-sigma ADC can perform continuous high-resolution measurements (e.g., temperature) while SAR ADCs acquire fast transient signals (e.g., motor current peaks) - all synchronized via DSI routing.
Is external memory required for typical applications?
No - 256 KB flash and 64 KB RAM suffice for most PSoC 5LP applications including USB HID devices, CapSense® interfaces, and CAN node firmware. External memory is only needed for large waveform buffers, OTA update staging, or advanced DSP algorithms exceeding on-chip RAM capacity.
