Product details
Overview
CY8C5288LTI-LP090 from Infineon Technologies (formerly Cypress Semiconductor) is a 32-bit programmable System-on-Chip (PSoC® 5LP) integrating an Arm® Cortex®-M3 CPU, configurable analog/digital peripherals, 256 KB flash, 64 KB RAM, and CapSense® support. It operates from 1.71–5.5 V across –40 to +85 °C, delivers up to 80 MHz performance, and supports USB 2.0 Full-Speed, I²C, SPI, and PWM functions in industrial HMI and sensor node applications.
For engineers reviewing the CY8C5288LTI-LP090 datasheet, CY8C5288LTI-LP090 pinout, CY8C5288LTI-LP090 application, or CY8C5288LTI-LP090 equivalent, key selection criteria include its 72-pin TQFP package, dual-domain power management (300 nA hibernate), SAR ADC + DAC analog capability, UDB-based digital reconfigurability, and integrated USBIO with internal oscillator timing.
Technical Context
The CY8C5288LTI-LP090 implements a tightly coupled architecture where the Arm Cortex-M3 core interfaces directly with a 24-UDB digital array and dedicated analog subsystem (12-bit SAR ADC, 8-bit DAC, two comparators, 1.024 V reference). Its routing fabric enables any peripheral function-including USB, I²C, or CapSense-to be assigned to any of 62 GPIOs or eight SIO pins with programmable thresholds and 25 mA sink capability.
Power management includes a boost regulator (0.5–5 V output), six independent power domains, and three low-power modes: 2 µA sleep and 300 nA hibernate with full RAM retention. Clocking combines a 3–74 MHz IMO (2% accuracy at 3 MHz), PLL for 80 MHz operation, and 32.768 kHz RTC crystal support-enabling precise timing control across mixed-signal embedded systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY8C5888LTI-LP097 | Higher memory (512 KB flash, 128 KB RAM), same package and peripheral set - no change in clocking or analog specs. | Required for firmware with large RTOS footprint or extensive data buffering; identical pinout enables drop-in upgrade path. | Select when firmware size exceeds 256 KB or RAM usage exceeds 64 KB - otherwise CY8C5288LTI-LP090 offers optimal cost/performance balance. |
| STM32F411RE | No integrated CapSense®, no UDB-based digital reconfigurability, lower analog integration (no DAC/comparator), but higher CPU clock (100 MHz) and FPU. | Suitable for compute-intensive control loops but requires external touch controller and signal chain components for equivalent analog functionality. | Choose only if floating-point math dominates workload and analog integration is handled externally - adds BOM cost and board space vs. PSoC 5LP's single-chip solution. |
Compared with CY8C5288LTI-LP090, CY8C5888LTI-LP097 offers scalable memory headroom within identical packaging and feature set, while STM32F411RE trades analog/digital configurability for raw CPU throughput - making the former ideal for firmware growth and the latter for pure computational tasks with external analog support.
