Product details
Overview
CY8C5488FNI-LP212T from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 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 up to 80 MHz CPU clock, and delivers ultra-low-power operation with 300 nA hibernate mode. Used in embedded control systems requiring mixed-signal integration, such as industrial sensor nodes and medical handheld devices.
For engineers reviewing the CY8C5488FNI-LP212T datasheet, CY8C5488FNI-LP212T pinout, CY8C5488FNI-LP212T application, or CY8C5488FNI-LP212T equivalent, key selection criteria include its 72-pin QFN package, dual ADC architecture (delta-sigma + SAR), CapSense® support for 62 sensors, programmable UDB array, and integrated USB PHY with TID#10840032 certification.
Technical Context
The CY8C5488FNI-LP212T implements a tightly coupled mixed-signal SoC architecture centered on an Arm Cortex-M3 core running at up to 80 MHz, backed by a 24-channel DMA controller and hierarchical interrupt system. Its digital subsystem relies on 24 Universal Digital Blocks (UDBs) that implement user-defined logic, communication protocols (I²C, SPI, UART, LIN), and timing functions via graphical or HDL-based configuration in PSoC Creator™.
Analog functionality is delivered through two independent ADCs (8–12-bit delta-sigma and 12-bit SAR), two 8-bit DACs, four comparators, two opamps, and two programmable SC/CT blocks supporting PGA, TIA, mixer, and sample-and-hold topologies. All analog and digital resources are routed flexibly to any of 72 I/O pins-including eight SIOs with 25 mA sink capability and overvoltage tolerance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable mixed-signal MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C5888LTI-LP097 | Same PSoC 5LP family, 100-pin TQFP, 256 KB flash, but higher I/O count (84 GPIOs) and no USB PHY-requires external USB transceiver. | Better suited for high-pin-count industrial PLC modules where USB is not required and board space allows TQFP. | Select when needing >72 I/Os and willing to add external USB PHY; avoid if USB integration and QFN footprint are mandatory. |
| STM32F303VCT6 | Arm Cortex-M4F, 256 KB flash, 48 KB RAM, no integrated CapSense® or UDBs; analog subsystem limited to 12-bit ADC + 12-bit DAC + 2 opamps. | Targeted at cost-sensitive motor control with FPU, but lacks hardware-accelerated capacitive sensing and reconfigurable digital logic. | Choose for floating-point math-intensive tasks (e.g., PID tuning) where CapSense® and UDB flexibility are unnecessary. |
Compared with CY8C5488FNI-LP212T, CY8C5888LTI-LP097 trades USB integration for higher I/O density and TQFP manufacturability, while STM32F303VCT6 offers FPU acceleration at the expense of programmable analog/digital fabric-making the CY8C5488FNI-LP212T optimal for rapid mixed-signal prototyping with minimal external components.

FAQ
Does CY8C5488FNI-LP212T support USB device enumeration without external components?
Yes. The part integrates a certified USB 2.0 Full-Speed PHY (TID#10840032) with internal termination resistors and oscillator, enabling plug-and-play enumeration on Windows, macOS, and Linux hosts using only the onboard 3.3 V LDO and standard USB connector wiring-no external transceiver or crystal required.
What development tools are required to configure its programmable analog blocks?
PSoC Creator™ IDE (free download from infineon.com) is mandatory for configuring SC/CT blocks, CapSense®, and UDBs. It provides drag-and-drop schematic entry, automatic code generation, and real-time parameter tuning for PGA gain, TIA feedback, and delta-sigma oversampling ratio-no manual register programming needed.
Can the 300 nA hibernate mode retain full 64 KB RAM contents?
Yes. In hibernate mode, the device retains all 64 KB SRAM contents while drawing only 300 nA typical from VDDD, provided VBACKUP ≥ 1.3 V is supplied to the dedicated backup domain. This enables instant wake-up with full context preservation-critical for energy-harvesting and battery-backed applications.
Is the 72-pin QFN package RoHS-compliant and lead-free?
Yes. The CY8C5488FNI-LP212T uses a lead-free, RoHS-compliant 72-pin QFN package (package code "FNI") with NiPdAu terminal finish and meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL3), qualified for standard reflow soldering profiles.
