Product details
Overview
CY7C65219-40LQXIT from Infineon Technologies (formerly Cypress) is a USB Billboard Controller (Dock Management Controller) designed for USB-C dock and monitor systems. It integrates a 48-MHz Arm® Cortex®-M0 MCU with 128-KB flash, 8-KB SRAM, full-speed USB 2.0 device controller, hardware crypto engine (AES/SHA-256/RSA-2048), and four reconfigurable serial communication blocks (SCBs), enabling firmware update and status reporting for connected USB PD and hub controllers in industrial-temperature docks.
For engineers reviewing the CY7C65219-40LQXIT datasheet, CY7C65219-40LQXIT pinout, CY7C65219-40LQXIT application, or CY7C65219-40LQXIT equivalent, key selection criteria include USB Billboard v1.21 compliance, signed/unsigned firmware update over USB, ±8-kV IEC61000-4-2 ESD on DPLUS/DMINUS, 20 GPIOs with OVT support, and 40-QFN industrial-grade packaging.
Technical Context
The CY7C65219 implements a dedicated USB Billboard Device Class v1.21 stack via its integrated full-speed USB 2.0 PHY and device controller, supporting vendor-defined interfaces for firmware distribution to downstream dock ICs. Its Cortex-M0 subsystem executes authenticated firmware updates using hardware-accelerated SHA-256 and RSA-2048 crypto blocks.
Four SCBs provide runtime-reconfigurable I2C (up to 1 Mbps Fast Mode Plus), SPI, or UART connectivity to USB PD controllers and hubs; two SCBs (P0.0/P0.1) feature overvoltage-tolerant I/O for hot-swap-safe I2C bus interfacing. Power management includes Deep Sleep (30 µA), Sleep (3.5 mA), and RESET modes with integrated POR and WIC wakeup capability.

| Reconfigurable Serial Interface | Four SCBs dynamically switch between I2C (1 Mbps Fast Mode Plus), SPI (master/slave), or UART - reducing BOM count and enabling flexible inter-IC communication |
| System-Level ESD Robustness | Integrated ±8-kV contact / ±15-kV air-gap ESD protection on DPLUS/DMINUS eliminates need for external TVS diodes in dock designs |
| Low-Power Operation | Deep Sleep current of 30 µA with Wakeup Interrupt Controller (WIC) enables battery-backed dock presence detection without host polling |
Applications
| USB-C Dock Firmware Orchestration | Monitor Embedded Billboard Functionality |
|---|---|
Use Scenario: Multi-port USB-C dock with integrated USB PD controller, USB 3.1 hub, and DisplayPort Alt Mode switching. IC Role / Device Role / Timing Role: Dock Management Controller acts as central firmware coordinator, handling host-initiated updates to PD and hub ICs via SCB interfaces while presenting Billboard descriptors over USB. Use Value: Enables single-cable firmware maintenance across all dock ICs without disassembly; reduces field service cost and improves security via signed image validation. | Use Scenario: Smart monitor with USB-C upstream port, embedded USB PD sink, and auxiliary peripherals (e.g., USB keyboard, Ethernet). IC Role / Device Role / Timing Role: Provides Billboard class enumeration to host OS when docked, reporting alternate mode capabilities and error states (e.g., "PD contract failed") via standardized USB descriptor strings. Use Value: Eliminates custom driver development; ensures Windows/macOS native recognition of monitor capabilities and failure conditions without OEM-specific software. |
| Industrial USB Hub Management | Secure Peripheral Update Gateway |
Use Scenario: Ruggedized industrial docking station for factory-floor tablets, requiring reliable hot-plug detection and power negotiation under EMI-heavy environments. IC Role / Device Role / Timing Role: Manages USB PD policy engine communication and monitors VBUS stability via SCB-linked PD controller; triggers Billboard alerts on overcurrent or thermal fault. Use Value: Prevents unsafe power delivery during manufacturing line operation; maintains USB enumeration integrity despite voltage transients common in 24 VDC plant power systems. | Use Scenario: Medical display cart with detachable peripherals (barcode scanner, RFID reader) requiring secure, auditable firmware updates over hospital IT network. IC Role / Device Role / Timing Role: Acts as authenticated gateway: validates RSA-signed firmware images before forwarding to peripheral controllers via I2C, logging update success/failure to host via USB vendor interface. Use Value: Meets FDA cybersecurity guidance (e.g., 21 CFR Part 11) by enforcing cryptographic chain-of-trust and tamper-evident update logs without adding external secure elements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar USB Billboard controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CY7C65215-40LQXIT | Same die, reduced peripheral set: only 2 SCBs, no TCPWM blocks, 64-KB flash, no crypto acceleration | Limited to basic billboard reporting; cannot perform signed firmware updates or manage complex multi-IC docks | Select when cost-sensitive, low-feature dock designs require only unsigned firmware distribution and minimal peripheral control |
| USB2514B-AEZG | USB 2.0 hub controller with integrated Billboard functionality; no MCU, no flash, no firmware update capability | Fixed-function Billboard only; no host-side firmware update orchestration or custom descriptor generation | Select when Billboard function is strictly passive (descriptor-only) and dock ICs handle their own firmware updates independently |
Compared with CY7C65215-40LQXIT and USB2514B-AEZG, the CY7C65219-40LQXIT uniquely combines full MCU programmability, hardware crypto, and multi-IC firmware coordination-enabling secure, upgradable dock architectures rather than static or externally managed solutions.

FAQ
What USB Billboard Device Class version does CY7C65219-40LQXIT implement?
The CY7C65219-40LQXIT implements USB Billboard Device Class specification v1.21, certified by USB-IF (TID#1534). It supports mandatory descriptors including bcdVersion, iAssociatedInterface, and iBCDVersion, and reports standardized error codes such as "Incompatible PD contract" or "Alternate mode configuration failed" to host operating systems without custom drivers.
Does CY7C65219-40LQXIT support both signed and unsigned firmware updates?
Yes - it supports both unsigned firmware updates (SHA-256 hash verification only) and signed firmware updates (RSA-2048 public-key signature + SHA-256). Signed updates require private key signing using Infineon's EZ-PD Dock Image Creation Tool and validated against the device's embedded public key stored in flash.
Can CY7C65219-40LQXIT operate with mixed I/O voltage levels?
Yes - it features separate VDDIO (1.71–5.5 V) and VDDD (2.7–5.5 V) supplies, allowing GPIOs to interface directly with 1.8-V, 3.3-V, or 5-V peripherals without level shifters. Pins P0.0 and P0.1 are overvoltage-tolerant up to 5.5 V, enabling safe I2C connection to USB PD controllers operating at higher voltages.
What is the minimum current consumption in Deep Sleep mode?
The CY7C65219-40LQXIT draws 30 µA in Deep Sleep mode, with the main regulator and most hard-IPs powered down. The Deep Sleep regulator remains active, sustaining the Wakeup Interrupt Controller (WIC) and retaining SRAM content, enabling wake-on-USB event or GPIO edge detection without host polling.
