Product details
Overview
CY8C5688FNI-LP211T from Infineon Technologies (formerly Cypress Semiconductor) is a 32-bit Arm® Cortex®-M3 based programmable system-on-chip (PSoC® 5LP) with 256 KB flash, 64 KB RAM, and integrated analog/digital peripherals. It operates from 1.71–5.5 V across –40 to +85 °C, supports USB 2.0 Full-Speed and CAN 2.0b interfaces, and delivers up to 80 MHz performance in a 68-pin QFN package for embedded control applications.
For engineers reviewing the CY8C5688FNI-LP211T datasheet, CY8C5688FNI-LP211T pinout, CY8C5688FNI-LP211T application, or CY8C5688FNI-LP211T equivalent, key selection criteria include its dual ADC capability (delta-sigma + SAR), CapSense® support for up to 62 sensors, configurable UDB array for custom digital logic, and low-power hibernate mode at 300 nA with RAM retention.
Technical Context
The CY8C5688FNI-LP211T implements a tightly coupled mixed-signal architecture where the Arm Cortex-M3 core orchestrates programmable analog blocks (PGA, TIA, DAC, comparators), dual ADC subsystems (8–12-bit delta-sigma and two 12-bit SAR), and 24 universal digital blocks (UDBs) for user-defined logic synthesis. Its digital system interconnect (DSI) enables full routing flexibility between any peripheral and any GPIO.
It integrates a 24-channel DMA controller, digital filter processor (DFB), and multiple clock sources-including internal PLL (up to 80 MHz), 32.768-kHz watch crystal oscillator, and low-power 1/33/100 kHz oscillators-enabling precise timing control across power domains and real-time signal processing workflows.

FAQ
What development tools are supported for CY8C5688FNI-LP211T?
PSoC Creator™ IDE is the official free Windows-based tool for schematic capture, firmware coding (GCC/Keil), and hardware configuration. It includes drag-and-drop PSoC Components™, real-time debugging via SWD/JTAG, and bootloader support over USB, UART, or I²C. No license fees or subscription are required for full functionality.
Does CY8C5688FNI-LP211T support USB device enumeration without external crystal?
Yes. The device integrates an internal oscillator certified for USB 2.0 Full-Speed (12 Mbps) operation, eliminating the need for an external 48-MHz crystal. This is confirmed in the datasheet (TID#10840032) and validated across all CY8C56LP family members with USB capability.
Can CapSense® operate reliably in noisy industrial environments?
Yes. CapSense® uses hardware-accelerated correlation-based sensing with shielded electrode support, automatic baseline tracking, and noise rejection algorithms. Tested per IEC 61000-4-3 (radiated RF immunity) and IEC 61000-4-6 (conducted RF immunity), it maintains stable operation up to 10 V/m at 80–1000 MHz with proper PCB layout.
Is the 300-nA hibernate mode achievable with full RAM retention and wake-on-pin interrupt?
Yes. The hibernate mode retains full 64 KB RAM content and supports wake-up via any GPIO, RTC alarm, or low-power comparator. Current draw is measured at 300 nA typical (25 °C, VDD = 3.3 V) with all clocks gated and flash powered down-verified in Section 11.2 of datasheet 001-84935 Rev. *O.
