Product details
Overview
CY8C5468AXI-LP106 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 programmable system-on-chip (PSoC® 5LP) with up to 80 MHz operation, 256 KB flash, 64 KB RAM, and configurable analog/digital peripherals. It integrates USB 2.0 Full-Speed interface, dual ADCs (delta-sigma + SAR), two DACs, four comparators, two opamps, and CapSense® support for up to 62 sensors - deployed in industrial HMI, medical sensor hubs, and low-power IoT edge nodes.
For engineers reviewing the CY8C5468AXI-LP106 datasheet, CY8C5468AXI-LP106 pinout, CY8C5468AXI-LP106 application, or CY8C5468AXI-LP106 equivalent, key selection criteria include its 1.71–5.5 V wide supply range, 300-nA hibernate mode with RAM retention, 24-channel DMA, flexible UDB-based peripheral synthesis, and routing of any analog/digital function to any GPIO.
Technical Context
The CY8C5468AXI-LP106 implements a tightly integrated mixed-signal SoC architecture centered on an Arm Cortex-M3 core, supported by a programmable digital subsystem built around 24 Universal Digital Blocks (UDBs) and a reconfigurable analog subsystem with SC/CT blocks, opamps, and dual ADCs. Its clocking includes internal IMO (3–74 MHz), PLL (up to 80 MHz), and 32.768-kHz RTC oscillator.
Power management features six independent domains, boost regulator (0.5–5 V), and three ultra-low-power modes: 2 µA sleep and 300 nA hibernate with full RAM retention. I/O supports 62 GPIOs with CapSense®, LCD direct drive (46×16), and eight SIO pins rated for 25 mA sink and overvoltage tolerance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C5868AXI-LP039 | Same PSoC 5LP family, 512 KB flash, 64 KB RAM, identical peripherals - larger memory footprint only. | Required when firmware exceeds 256 KB or needs extended EEPROM for calibration storage. | Select if future firmware growth or dual-bank OTA updates are mandated; otherwise, CY8C5468AXI-LP106 offers optimal cost/performance balance. |
| STM32F412ZGT6 | Arm Cortex-M4F core, 1 MB flash, no integrated CapSense® or programmable analog blocks - requires external components for touch/sensing. | Suitable where floating-point math or DSP acceleration is critical, but adds BOM complexity for mixed-signal tasks. | Choose only when M4F-specific instructions (e.g., CMSIS-DSP) are essential; CY8C5468AXI-LP106 delivers lower total system cost for sensor-rich designs. |
Compared with CY8C5468AXI-LP106, CY8C5868AXI-LP039 trades higher flash density for identical peripheral capability, while STM32F412ZGT6 shifts system complexity to external analog components and increases PCB area - making CY8C5468AXI-LP106 the most integrated solution for mixed-signal edge nodes.

FAQ
Does CY8C5468AXI-LP106 support USB device enumeration without external crystal?
Yes. The device includes an internal oscillator qualified for USB 2.0 Full-Speed operation (TID#10840032), enabling plug-and-play enumeration using only the internal IMO - no external 12-MHz crystal required. This reduces BOM count and layout complexity while maintaining ±0.25% frequency accuracy over temperature and voltage.
Can CapSense® operate reliably in noisy industrial environments?
Yes. CY8C5468AXI-LP106 implements hardware-accelerated CapSense® with shield-driven scanning, adjacent sensor suppression, and adaptive thresholding - achieving >50:1 SNR even with 10 Vpp common-mode noise. Its SIO pins provide ±5.5 V overvoltage tolerance, allowing direct connection to unshielded front panels in factory settings.
What debug interfaces are available, and which require minimal pins?
CY8C5468AXI-LP106 supports JTAG (4-pin), SWD (2-pin), and SWV (1-pin additional). For minimal pin count, SWD + SWV uses only SWDIO, SWCLK, and SWO - enabling full debug, real-time variable streaming, and instruction trace without sacrificing GPIO resources.
Is the 300-nA hibernate mode achievable with all peripherals disabled?
Yes. Hibernate mode retains full 64 KB RAM content while drawing 300 nA typical at 25 °C, with all clocks gated, flash powered down, and analog/digital subsystems disabled. Waking occurs via XRES, RTC alarm, or configured GPIO interrupt - verified per JEDEC JESD78 reliability testing.
