Texas Instruments TUSB9260PVP

Overview

TUSB9260PVP from Texas Instruments is a USB 3.0 to SATA bridge IC integrating an ARM Cortex-M3 microcontroller, SuperSpeed USB 3.0 PHY, and AHCI-compliant SATA 2.6 controller. It supports UASP and BOT protocols, operates with 40-MHz crystal or oscillator input, and delivers up to 6 Gbps SATA Gen II (3.0 Gbps per lane) and 5 Gbps USB 3.0 data transfer for external HDD/SSD enclosures.

For engineers reviewing the TUSB9260PVP datasheet, TUSB9260PVP pinout, TUSB9260PVP application, or TUSB9260PVP equivalent, key selection criteria include dual-protocol firmware support (UASP/BOT), integrated 80-kB RAM, 12 GPIOs with PWM LED control, JTAG debug capability, and RoHS-compliant HTQFP-64 packaging for compact storage interface designs.

Technical Context

The TUSB9260PVP implements a full USB 3.0 device stack-including UASP as primary interface and BOT as fallback-alongside an AHCI-compliant SATA host bus adapter supporting gen1i/gen1m/gen2i/gen2m negotiation. Its ARM Cortex-M3 subsystem executes boot code from ROM and loads customizable firmware from SPI flash.

Signal integrity is maintained via adaptive equalization in the SuperSpeed receiver, configurable clock source selection (40 MHz crystal or oscillator), and dedicated power domains (VDD=1.1 V, VDDR18=1.8 V, VDD33=3.3 V). The device performs OOB sequence initiation, device signature detection, and IDENTIFY DEVICE command execution autonomously during SATA link training.

FAQ

What USB and SATA standards does the TUSB9260PVP support?

The TUSB9260PVP supports USB 3.0 SuperSpeed (5 Gbps), USB 2.0 High-Speed (480 Mbps), and Full-Speed (12 Mbps) with UASP and BOT class compliance. For SATA, it implements AHCI-compliant Serial ATA Revision 2.6, supporting Gen I (1.5 Gbps) and Gen II (3.0 Gbps) speeds including gen1i/gen1m/gen2i/gen2m link negotiation. These capabilities are confirmed in the SLLS962D datasheet sections 1.1 and 2.2.

Does the TUSB9260PVP require external memory, and what type is supported?

Yes, the TUSB9260PVP requires external SPI flash memory to store firmware images and custom descriptors. The device boots from internal ROM, then loads executable code into its 80-kB on-chip RAM via the SPI interface using SPI_CS0 (Pin 21) as the primary chip select. SPI_CS1 and SPI_CS2 (Pins 22–23) support additional peripherals but are not required for basic operation. This architecture is detailed in Section 3.1 of the SLLS962D datasheet.

How does the TUSB9260PVP handle USB speed negotiation and fallback?

The TUSB9260PVP first attempts SuperSpeed connection upon VBUS detection. If training fails within timeout, it enables DP pull-up and connects as USB 2.0 High-Speed or Full-Speed depending on host capability. When connected at SuperSpeed, UASP is presented as primary interface; BOT becomes primary only if UASP is unsupported by the host stack. This behavior is defined in Sections 3.1 and 3.2 of the SLLS962D datasheet and ensures seamless interoperability across USB generations.

What clock sources are compatible with the TUSB9260PVP, and how is frequency selected?

The TUSB9260PVP accepts either a 40-MHz crystal (with XI/XO pins and 1-MΩ feedback resistor) or a 40-MHz CMOS oscillator (XI driven, XO floating, VSSOSC grounded). Frequency selection is hardwired via FREQSEL[1:0] pins (31,30), where logic '11' configures the PLL for 40-MHz input. Crystal load capacitance must be 12–24 pF; oscillator jitter must stay below 0.8 ps (RJ) to meet USB 3.0 compliance. These requirements are specified in Tables 5-1 and 5-2 of the SLLS962D datasheet.

Can the TUSB9260PVP support SATA power management features like partial/slumber?

No, the TUSB9260PVP firmware does not implement SATA Partial or Slumber power management states. Power consumption data in Table 7-1 shows idle current only for U0 (active) state with no SATA power management enabled. The device supports USB U1/U2/U3 link power management but relies on host-initiated commands for SATA device sleep/wake transitions. This limitation is implied by omission in Sections 1.1 and 3.1 of the SLLS962D datasheet and confirmed in power tables.
