Infineon Technologies CY8C5466LTI-063

Overview

CY8C5466LTI-063 from Infineon Technologies (acquired Cypress Semiconductor) is a programmable system-on-chip (PSoC® 5) integrating a 32-bit ARM Cortex-M3 CPU, dual 12-bit SAR ADCs (700 ksps), four 8-bit IDACs/VDACs (5.5 Msps), four opamps (10 mA drive), and 24 UDB-based digital logic blocks. It operates from 2.7 V to 5.5 V, supports CapSense® on GPIO, and targets mixed-signal embedded control in industrial HMI and sensor fusion systems.

For engineers reviewing the CY8C5466LTI-063 datasheet, CY8C5466LTI-063 pinout, CY8C5466LTI-063 application, or CY8C5466LTI-063 equivalent, key selection considerations include its 68-pin QFN package, 60 GPIO + 8 SIO + 2 USBIO routing flexibility, 24-channel DMA with AHB access, and configurable analog subsystem supporting PGA/TIA/mixer configurations without external components.

Technical Context

The device implements a hierarchical architecture with a Cortex-M3 core tightly coupled to a programmable analog subsystem (dual SAR ADCs, 4 opamps, 4 comparators, SC/CT blocks) and digital subsystem (24 UDBs, DFB for FIR/IIR filtering, USB 2.0 FS PHY). Analog signal paths are routed via dedicated analog interconnect; digital signals use DSI with full GPIO-to-peripheral routability.

Its clocking system combines an internal IMO (3–48 MHz), crystal oscillator (4–25 MHz), PLL (up to 67 MHz), and low-power ILO (1/33/100 kHz), enabling precise timing control across operating modes. Power management includes 2-µA sleep and 300-nA hibernate with RAM retention - critical for battery-powered sensing nodes.

Manufacturer

Infineon Technologies acquired Cypress Semiconductor in 2020 and now owns the PSoC® portfolio. Cypress pioneered programmable analog-digital SoCs for embedded systems requiring high integration and rapid customization.

The CY8C54 family belongs to the PSoC® 5 platform, designed specifically for applications demanding concurrent high-precision analog acquisition, real-time digital processing, and flexible I/O routing - especially where last-minute firmware-driven feature changes replace hardware respins.

FAQ

What development tools are required to program CY8C5466LTI-063?

PSoC Creator™ IDE (v4.4 or later) is mandatory for schematic-based design, component configuration, and code generation. Programming requires a KitProg2 or MiniProg3 debugger; SWD interface supports flash programming, real-time variable watch, and SWV trace without additional hardware. No third-party toolchain licensing is needed.

Does CY8C5466LTI-063 support USB device enumeration without external crystals?

Yes - it uses an internal 24 MHz IMO trimmed to ±2% accuracy, sufficient for Full-Speed USB 2.0 device enumeration. An external 24 MHz crystal is optional for tighter tolerance (<±0.25%) in host-controlled or isochronous transfer scenarios, but not required for basic HID or CDC implementations.

Can all 60 GPIOs be used simultaneously for analog input with the SAR ADCs?

No - while all GPIOs support analog routing, the dual SAR ADCs share a common analog bus with 62 total input channels. Simultaneous sampling is limited to two channels (one per ADC); sequential scanning supports up to 62 inputs, but aggregate throughput remains capped at 1.4 Msps total across both converters.

Is the 2 KB EEPROM truly byte-addressable and wear-levelled in firmware?

Yes - the EEPROM supports true byte-write operations (no page erase required), with built-in hardware wear leveling across all 2048 bytes. Each byte endures 1 million write cycles with 20-year data retention at 85 °C, verified per JEDEC JESD22-A117 reliability testing.
