Texas Instruments TUSB6020PFCR

Overview

TUSB6020PFCR from Texas Instruments is an evaluation module (EVM) built around the TUSB6020 USB 2.0 high-speed On-The-Go (OTG) dual-role controller IC with integrated PHY, designed for seamless VLYNQ interface connectivity to TI DSP platforms including TMS320C6437 and DM6437. It supports USB OTG host/device operation at low (1.5 Mb/s), full (12 Mb/s), and high speed (480 Mb/s), and enables USB mass storage device emulation.

For engineers reviewing the TUSB6020PFCR datasheet, TUSB6020PFCR pinout, TUSB6020PFCR application, or TUSB6020PFCR equivalent, this EVM provides validated hardware reference for USB OTG integration with VLYNQ-enabled DSPs, clock source selection (19.2 MHz oscillator or 24 MHz crystal), GPIO-controlled configuration, and power-regulated operation across 1.5 V, 1.8 V, and 3.3 V rails.

Technical Context

The TUSB6020PFCR implements a complete USB 2.0 OTG dual-role controller with integrated transceiver, supporting all three USB speeds and compliant with USB 2.0 Specification Revision 2.0 and OTG Supplement Revision 1.3. Its VLYNQ serial interface operates at up to 100 MHz with 4-bit TX/RX data lanes, CRUN control, and CLK synchronization.

Hardware configuration is managed via eight GPIO pins (GPIO0–GPIO7), where GPIO7 must be pulled low for proper initialization and GPIO6 selects between XI (24 MHz) and CLKIN (19.2 MHz) clock sources. The board integrates TI power management ICs including TPS77618 (1.8 V LDO), TPS70848 (dual 3.3 V/1.5 V LDO), and TPS2051B (VBUS power switch), enabling precise rail control and measurement via test jumpers.

FAQ

What is the primary function of the TUSB6020PFCR?

The TUSB6020PFCR is an evaluation module for the TUSB6020 USB 2.0 OTG dual-role controller IC. It provides a ready-to-use hardware platform to validate USB host/peripheral functionality, VLYNQ interface timing, clock source selection, and power rail behavior when interfacing with TI DSPs such as the TMS320C6437. The TUSB6020PFCR itself is not a standalone IC but a fully assembled and tested reference board.

Which DSP platforms is the TUSB6020PFCR compatible with?

The TUSB6020PFCR is explicitly compatible with TI DSP evaluation modules equipped with an active VLYNQ interface and mini-PCI edge connector, including the TMS320C6437 Digital Video Development Platform, TMS320C6424 EVM, and DaVinci LC EVM. Compatibility requires matching VLYNQ signal mapping, CRUN/CLK timing, and 128-pin mechanical alignment - all verified in the SLAU242 User's Guide.

How is the clock source selected on the TUSB6020PFCR?

Clock source selection on the TUSB6020PFCR is controlled by GPIO6 at power-up: when GPIO6 is pulled low (via Switch 7 OFF), the TUSB6020 uses the 24 MHz crystal (X2) connected to XI/XO pins; when GPIO6 is pulled high (Switch 7 ON), it uses the 19.2 MHz oscillator (X1) connected to CLKIN. This configuration is fixed at boot and cannot be changed dynamically in firmware.

Does the TUSB6020PFCR support USB mass storage device mode?

Yes, the TUSB6020PFCR has been validated to operate as a USB mass storage device. When configured via software and GPIO settings, the underlying TUSB6020 IC enumerates as a removable disk drive on a host PC. This capability is demonstrated in the SLAU242 User's Guide using Code Composer Studio and UART-based command prompts to initiate storage-class enumeration.

What power measurement capabilities does the TUSB6020PFCR offer?

The TUSB6020PFCR includes 11 dedicated test jumpers (J37, J38, J39, J40, J42, J43, J45, J46, J51, J59, and J44) placed in series with individual voltage rails - including VDDA_3.3V, VDDD_1.5V, VDDCM_1.5V, VDDA_1.5V, VDD_1.8V_TUSB6020, and VBUS - allowing precise current measurement by cutting the trace and inserting an ammeter. Each jumper is labeled with silk-screened rail names for unambiguous identification.
