Product details
Overview
CY7C68003-20FNXIT from Cypress Semiconductor is a USB 2.0 ULPI transceiver supporting Full Speed and High Speed modes, featuring integrated PLL (13/19.2/24/26 MHz), on-chip oscillator, and 1.8 V core supply with 1.8–3.3 V I/O voltage range. It implements UTMI+ Level 0 interface, supports UART pass-through mode, and operates across –40 °C to +85 °C in a 2.14 × 1.76 mm 20-pin WLCSP package for mobile handset applications.
For engineers reviewing the CY7C68003-20FNXIT datasheet, CY7C68003-20FNXIT pinout, CY7C68003-20FNXIT application, or CY7C68003-20FNXIT equivalent, key selection criteria include ULPI SDR 8-bit interface compliance, integrated termination/pull-up resistors, sleep-mode current (5 µA), VBATT input range (3.0–5.775 V), and industrial temperature operation.
Technical Context
The CY7C68003-20FNXIT implements a UTMI+ Level 0-compliant USB 2.0 PHY with dedicated ULPI link interface, enabling direct connection to host/device controllers without external level-shifting or timing compensation. Its internal PLL locks to 13/19.2/24/26 MHz reference inputs and generates precise 480 MHz HS clock with fractional multiplication.
It integrates USB FS/HS analog front-end with on-die 1.5 kΩ pull-up resistor on DP, 15 kΩ termination on DP/DM, and supports Carkit UART pass-through via DP/DM signal remapping to DATA[1:0]. Power domains are isolated: VCC (1.7–1.9 V), VIO (1.7–3.6 V), and VBATT (3.0–5.775 V).

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB 2.0 ULPI transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMSC USB3317C-EZK | Supports UTMI+ Level 1; includes integrated USB switch and VBUS detection; no UART pass-through mode. | Targeted at embedded host applications with dual-role capability; lacks Carkit mode and WLCSP option. | Choose when UTMI+ Level 1 features or VBUS sensing are required; not drop-in for CY7C68003-20FNXIT's WLCSP footprint. |
| Microchip USB2502-AEZG | USB 2.0 hub controller (not transceiver); integrates PHY + link layer; requires external crystal only at 12/24 MHz. | Designed for multi-port hub systems; not suitable as standalone PHY replacement. | Select only for hub-based architectures; incompatible as direct CY7C68003-20FNXIT functional substitute. |
Compared with SMSC USB3317C-EZK and Microchip USB2502-AEZG, the CY7C68003-20FNXIT uniquely combines WLCSP packaging, UART pass-through, and 5 µA sleep current-making it optimal for space-constrained, battery-powered USB device endpoints where dual-mode serial communication is needed.

FAQ
What is the function of the RESET_N pin on CY7C68003-20FNXIT?
The RESET_N pin serves three distinct functions: asserting it for tSTATE places the device into Sleep Mode; asserting it during power-on initiates Configuration Mode; and deasserting it exits Configuration Mode. When unused, it must be pulled high to ensure normal operation. All ULPI interface pins are tristated during Sleep and Configuration Modes.
Does CY7C68003-20FNXIT support USB host mode?
No. The CY7C68003-20FNXIT supports USB device mode only, as confirmed in its official documentation. It implements UTMI+ Level 0 for device-side PHY functionality and lacks host-side signaling logic, VBUS sensing, or OTG capability. It must be paired with a UTMI+-compliant USB device controller.
Can the CY7C68003-20FNXIT operate without an external crystal?
Yes - it accepts either a 13/19.2/24/26 MHz crystal across XI/XO or a single-ended LVCMOS clock applied to XI. The XO pin is not bonded in the 20-pin WLCSP package, so crystal operation requires proper load capacitance (12 pF ±5%) and trace layout per Figure 2 in the datasheet. External clock input bypasses the oscillator circuit.
What is the purpose of UART pass-through mode?
UART pass-through mode repurposes DP and DM pins as UART TXD and RXD using DATA[0] and DATA[1] under software control (Carkit Mode bit in Interface Control Register). This enables car-kit accessories to communicate over the same USB connector without additional wiring, with automatic clock gating to reduce power during UART operation.
