Product details
Overview
CY8C5867AXI-LP024 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 USB 2.0 Full-Speed 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 sensor fusion systems.
For engineers reviewing the CY8C5867AXI-LP024 datasheet, CY8C5867AXI-LP024 pinout, CY8C5867AXI-LP024 application, or CY8C5867AXI-LP024 equivalent, key selection criteria include its dual ADC architecture (delta-sigma + SAR), programmable UDB array for custom logic, USBIO-capable I/O routing, and integrated DFB for real-time digital filtering-critical for mixed-signal edge-node designs.
Technical Context
The device implements a tightly coupled subsystem architecture: the Arm Cortex-M3 core (up to 80 MHz) interfaces directly with a 24-channel DMA controller and a dedicated 24-bit digital filter processor (DFB), enabling deterministic signal processing without CPU intervention. Its analog subsystem includes four opamps, four comparators, and programmable SC/CT blocks supporting PGA, TIA, and mixer configurations.
Digital flexibility stems from 20–24 universal digital blocks (UDBs), each combining PAL/PLD logic and state machines, routable via DSI to any GPIO. Clocking includes three independent oscillators (IMO, ILO, WCO), PLL up to 80 MHz, and 12 programmable dividers-allowing concurrent peripheral clock domains with precise jitter 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 | Same die, 100-pin TQFP package, higher I/O count (72 GPIO), additional USBIO pin pair | Better suited for designs requiring >62 GPIOs or dual USB interfaces (e.g., host + device) | Select when board layout requires TQFP handling or needs extra routing flexibility for high-pin-count analog sensor arrays. |
| STM32F303VCT6 | Arm Cortex-M4F core, no integrated CapSense® or DFB; relies on external ADCs for >12-bit precision | Limited analog configurability; requires external components for touch or precision sensor front-ends | Choose only if existing STM32 toolchain familiarity outweighs need for integrated mixed-signal flexibility and ultra-low-power hibernate. |
Compared with CY8C5867AXI-LP024, the LP035 offers identical functionality in larger package for I/O expansion, while the STM32F303 sacrifices on-chip analog programmability and sub-µA hibernate capability-making the CY8C5867AXI-LP024 optimal for compact, battery-constrained, mixed-signal edge nodes.

FAQ
What debug interfaces does CY8C5867AXI-LP024 support?
CY8C5867AXI-LP024 supports JTAG (4-wire), Serial Wire Debug (SWD, 2-wire), Single Wire Viewer (SWV), and TracePort (5-wire) interfaces. All are implemented in silicon with Arm CoreSight debug modules, enabling full breakpoint control, real-time variable watch, instruction trace, and system-level event logging without external probes beyond standard SWD debuggers like KitProg3 or SEGGER J-Link.
Does CY8C5867AXI-LP024 include hardware security features?
Yes-it integrates flash security including read protection (lock bits), write protection per sector, and secure bootloader authentication via SHA-256 signature verification. The device also supports nonvolatile latches (NVLs) for tamper-evident configuration storage and hardware-assisted AES-128 encryption for secure firmware updates over I²C, SPI, or USB interfaces.
Can CY8C5867AXI-LP024 drive an LCD directly without external bias circuitry?
Yes-the device supports direct static and multiplexed LCD drive up to 46×16 segments using any GPIO pin. It provides programmable VLCD voltage generation (up to 5.5 V), internal charge pump, and frame frequency control registers, eliminating external LCD bias generators and reducing component count in portable display applications.
Is the internal 1.024 V reference stable enough for 16-bit ADC measurements?
The internal 1.024 V reference has ±0.1% initial accuracy and ±20 ppm/°C drift over –40 to +85 °C. When used with the delta-sigma ADC's internal gain calibration and offset trimming, it supports effective resolution up to 18 bits at 10 SPS-validated in AN81623 and production-tested across voltage/temperature corners.
