Infineon Technologies CY8C5467LTI-007

Overview

CY8C5467LTI-007 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 DACs (5.5 Msps), 24 UDBs, and full-speed USB 2.0. It operates from 2.7 V to 5.5 V, supports CapSense® on GPIO, and delivers up to 67 MHz performance in a 68-pin QFN package for embedded control with mixed-signal acquisition.

For engineers reviewing the CY8C5467LTI-007 datasheet, CY8C5467LTI-007 pinout, CY8C5467LTI-007 application, or CY8C5467LTI-007 equivalent, key selection criteria include its configurable analog/digital routing, 24-channel DMA support, low-power hibernate mode (300 nA), and USB + I²C + SPI peripheral integration - all validated for industrial sensor hubs and programmable HMI systems.

Technical Context

The device implements a hierarchical architecture with a Cortex-M3 core tightly coupled to a digital subsystem of 24 universal digital blocks (UDBs), each containing PLD logic and state machines, enabling custom peripherals like LIN, PRS, CRC, and quadrature decoders without external components. Its analog subsystem features two independent SAR ADCs with DMA-triggered DFB filtering, four opamps (10 mA drive), and SC/CT blocks configurable as PGAs or TIAs.

Clocking is fully programmable via internal IMO (3–48 MHz), crystal oscillator (4–25 MHz), PLL (up to 67 MHz), and 32.768 kHz RTC oscillator. Power management includes five low-power modes - including hibernate with RAM retention - and voltage domains supporting 1.2 V to 5.5 V I/O interfaces across four independent supply groups.

Manufacturer

Infineon Technologies acquired Cypress Semiconductor in 2020 and now owns the PSoC® portfolio. Cypress pioneered configurable mixed-signal SoCs with integrated analog/digital resources and programmable interconnect.

The CY8C54 family belongs to the PSoC® 5 platform, designed specifically for embedded systems demanding high analog accuracy, flexible digital logic, and rapid firmware-driven hardware reconfiguration - especially in industrial control, human-machine interface, and sensor fusion applications.

FAQ

Does CY8C5467LTI-007 support USB device functionality without external components?

Yes. It integrates a full-speed USB 2.0 PHY and controller capable of USB HID, CDC, and mass storage class operation. A 24 MHz external crystal is required for USB timing compliance, but no transceiver or level-shifting components are needed. The USBIO pins (P15[6]/P15[7]) provide ESD protection and differential signaling internally.

Can all 60 GPIOs be used simultaneously for CapSense®?

No. While CapSense® can be routed to any GPIO, the datasheet specifies that GPIOs with opamp outputs are not recommended for CapSense® due to noise coupling. Up to 32 dedicated CapSense® channels are supported concurrently, with automatic scanning and baseline tracking handled in hardware without CPU intervention.

What is the maximum achievable sample rate when using both SAR ADCs simultaneously?

Each SAR ADC achieves 700 ksps independently. When both are active and triggered synchronously (e.g., via DSI or timer), the aggregate throughput is 1.4 Msps. However, shared analog routing resources limit concurrent channel count - up to 16 analog inputs can be sampled per second across both ADCs with full 12-bit resolution and <0.5% INL.

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

Yes. The 2 KB EEPROM supports byte-level writes and erases with guaranteed 1 million endurance cycles and 20-year data retention. Wear leveling is implemented in hardware via a shadow-page mechanism - no firmware overhead is required to manage erase cycles or address mapping.
