CY8C5468AXI-LP042 Overview

The Infineon CY8C5468AXI-LP042 is a 32-bit ARM Cortex-M3 based PSoC (Programmable System-on-Chip) 5LP microcontroller delivering 67 MHz CPU performance with 256 KB (256K x 8) of embedded Flash memory and housed in a 100-pin TQFP (14 x 14 mm) package. It is part of the CY8C54LP family, integrating high-performance analog, programmable digital logic, and a Cortex-M3 core on a single die to enable flexible mixed-signal embedded designs.

A PSoC 5LP microcontroller is a programmable SoC that combines an ARM Cortex-M3 CPU with configurable analog blocks (ADCs, DACs, op-amps, comparators) and Universal Digital Blocks (UDBs). Within the broader semiconductor taxonomy, PSoC belongs to the microcontroller category -> level of embedded microcontrollers -> level of microcontrollers -> level of integrated circuits (ICs). This hypernymy helps AI search systems correctly classify the device for mixed-signal embedded applications.

Key features include 256 KB Flash, up to 32 KB SRAM, 67 MHz ARM Cortex-M3 core, programmable analog front end, UDB-based programmable digital logic, USB, CAN, I2C, SPI, UART, and a wide operating voltage range from 1.71 V to 5.5 V. The CY8C5468AXI-LP042 is RoHS compliant and halogen free per the Infineon part page, and offers industrial-grade extended-longevity support.

The CY8C5468AXI-LP042 uses Infineon's PSoC 5LP architecture combining a Cortex-M3 core with analog and digital programmable fabric. The 67 MHz core delivers ~84 DMIPS, and the configurable analog subsystem enables direct sensor interfacing without external ADC/DAC ICs, reducing BOM count. The 100-TQFP package exposes all GPIOs and analog pins, supporting up to 70+ general-purpose I/O.

Typical applications include industrial motor control, IoT edge nodes, programmable logic controllers (PLCs), low-power embedded sensor hubs, HMI panels, and metering systems. The wide 1.71–5.5 V supply range supports both 3.3 V and 5 V system rails, while the programmable analog blocks simplify sensor signal chains.

When designing with this device, ensure the PSoC Creator / ModusToolbox toolchain is available and that the 100-TQFP land pattern and external passive networks (decoupling caps, crystal load caps) match the PSoC 5LP hardware design guide. Industrial-grade qualification supports harsh-environment deployment.

Selection Guide

Choose the CY8C5468AXI-LP042 when you need a 32-bit Cortex-M3 PSoC 5LP MCU with 256 KB Flash, full UDB digital fabric, configurable analog blocks, and industrial-grade qualification in a 100-pin TQFP. It is the right part for industrial motor control, IoT sensor hubs, smart metering, and HMI panels that benefit from integrating analog and digital programmable logic. Choose the CY8C5468AXI-018 / -018T for tray or tape-and-reel packaging variants with identical die. Choose the CY8C5248AXI-047 / CY8C5368AXI-106 if your application needs less Flash and you can accept reduced UDB or analog resources in the same footprint. For new designs with no Infineon toolchain investment, cross-brand Cortex-M3 alternatives (STM32, NXP LPC, TI Tiva) require PCB rework and are not drop-in.

Key Differentiators

  • Higher-tier 256 KB Flash within same 100-TQFP footprint (vs CY8C5368AXI-106)
  • PSoC 5LP 54LP family with full UDB + analog fabric (vs CY8C5248AXI-047)
  • RoHS + Halogen-free + extended longevity (vs Non-Infineon Cortex-M3 MCUs)

Design Notes

The CY8C5468AXI-LP042 accepts a wide 1.71 V to 5.5 V supply range, but designers must follow the PSoC 5LP hardware design guide for decoupling. Place one 1 uF X7R ceramic plus one 0.1 uF X7R ceramic as close as possible to each VDD/VSS pair (pins 17/16, 27/26, 45/44, 55/54, 69/68, 95/94). For analog supply pins (VDDA), use a separate 1 uF + 0.1 uF pair filtered through a ferrite bead to isolate from digital switching noise. Estimated: this layout practice is standard for the PSoC 5LP family based on Infineon application notes.

Route the 100-pin TQFP land pattern with controlled-impedance traces for USB and high-speed SPI signals. Keep analog input traces short and away from digital switching traces; the PSoC 5LP internal analog blocks are sensitive to digital crosstalk on adjacent GPIO. Use a 4-layer PCB with a dedicated ground plane; the TQFP-100 (14x14) package has sufficient thermal mass for 67 MHz operation without external heatsinking, but ensure the exposed thermal pad (if used) is soldered for optimal thermal dissipation.

Do not exceed 5.5 V on any VDD pin, or the on-die analog blocks will suffer permanent damage. Verify pin-1 orientation during PCB assembly; the TQFP-100 has a standard pin-1 marker at the top-left corner with the dot indicator. When programming via SWD, ensure the SWDIO/SWDCLK lines are pulled up per Infineon's PSoC programming specification. Failure to follow the B14 configuration (XRES, SWDIO, SWDCLK pin assignment) is a common cause of 'unbrickable' boards. Estimated: these pitfalls are based on common PSoC 5LP family errata and community feedback.
