Product details
Overview
CY8C5688LTI-LP086 from Infineon Technologies (formerly Cypress) is a 32-bit Arm® Cortex®-M3 programmable system-on-chip (PSoC® 5LP) with up to 256 KB flash, 64 KB RAM, 80 MHz operation, full CAN 2.0b interface, and configurable analog/digital peripherals. It integrates ADCs, DACs, opamps, comparators, CapSense®, USB FS, and programmable logic for embedded control in industrial sensing and motor management systems.
For engineers reviewing the CY8C5688LTI-LP086 datasheet, CY8C5688LTI-LP086 pinout, CY8C5688LTI-LP086 application, or CY8C5688LTI-LP086 equivalent, key selection criteria include its 68-pin QFN package, 1.71–5.5 V supply range, hibernate mode (300 nA), dual SAR ADCs, and UDB-based peripheral customization capability.
Technical Context
The device implements a tightly coupled architecture where the Cortex-M3 CPU interfaces directly with a programmable digital subsystem built around 20–24 Universal Digital Blocks (UDBs), each containing PAL/PLD logic and state machines. Peripheral routing uses the Digital System Interconnect (DSI) fabric to map any function-including UART, SPI, LIN, CRC, or custom logic-to any GPIO.
Analog resources are managed through dedicated routing paths and four programmable SC/CT blocks supporting PGA, TIA, mixer, and sample-and-hold functions. Clocking includes internal PLL (up to 80 MHz), low-power oscillators (1/33/100 kHz), and external crystal support (4–25 MHz), all routed via 12 configurable dividers to peripherals or I/O.

| Digital Filter Block (DFB) | 24-bit, 64-tap fixed-point processor offloads FIR/IIR filtering from CPU - critical for real-time vibration analysis or audio preprocessing. |
| Bootloader Flexibility | Field-upgradable via I²C, SPI, UART, or USB using factory-programmed ROM bootloader - eliminates need for JTAG in production firmware updates. |
| Routing Architecture | Any analog or digital peripheral can be connected to any GPIO via DSI - reduces PCB layer count and eliminates fixed-function pin conflicts during layout. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STM32F412ZG | ARM Cortex-M4F core, no integrated analog configurability; relies on external ADC/DAC for precision sensing. | Lacks CapSense®, programmable SC/CT blocks, and DSI routing - requires more external components for mixed-signal designs. | Prefer when floating-point math or DSP extensions are required, but expect higher BOM cost and layout complexity for analog-heavy systems. |
| MAX32660 | ARM Cortex-M4, ultra-low-power focus (1.6 µA/MHz), but limited analog resources: single 12-bit SAR ADC, no DACs or opamps. | No CAN, no USB, no CapSense - suitable for wearable biosensors, not industrial control or HMI. | Select only for battery-constrained, single-sensor edge nodes where analog integration is minimal and communication is BLE-only. |
Compared with STM32F412ZG and MAX32660, CY8C5688LTI-LP086 uniquely combines full CAN/USB, dual SAR ADCs, four opamps, and CapSense® in a single chip - reducing system-level component count and enabling true mixed-signal programmability without external signal conditioning.

FAQ
What development tools are supported for CY8C5688LTI-LP086?
PSoC Creator™ IDE is the official free Windows-based tool, providing schematic capture, component drag-and-drop, C firmware generation, and debug via SWD/JTAG. It supports GCC and Keil MDK compilers. Programming is enabled through MiniProg3, KitProg, or onboard USB bootloader - no third-party tools required for full development flow.
Does CY8C5688LTI-LP086 support USB device enumeration without external crystal?
Yes - it includes an internal oscillator qualified for USB Full-Speed (12 Mbps) operation per TID#10840032, eliminating the need for an external 48 MHz crystal. This reduces BOM cost and board space while maintaining USB compliance for HID, CDC, and MSC class devices.
How many CapSense® buttons can be implemented simultaneously?
Up to 62 capacitive sensing electrodes can be scanned concurrently using the on-chip CapSense® subsystem. The device supports both self-capacitance and mutual-capacitance configurations, with hardware-accelerated baseline tracking and noise rejection - all without CPU intervention during scanning.
Is the 300 nA hibernate mode achievable with full RAM retention?
Yes - hibernate mode retains full 64 KB RAM content while drawing only 300 nA typical at 25°C. Wake-up sources include GPIO interrupts, RTC alarm, or CapSense® touch event. RAM retention is maintained across brown-out and supply cycling within the 1.71–5.5 V operating range.
