Texas Instruments TUSB6015IZQE

Overview

TUSB6015IZQE from Texas Instruments is a USB 2.0 High-Speed (480 Mbps) peripheral controller IC with integrated PHY, NOR Flash–like 16/32-bit multiplexed interface, six configurable endpoints (1 KB each), and industrial-grade operation (−40°C to 85°C). It supports synchronous burst DMA transfers at up to 65 MHz GPMC clock and delivers VBUS-tolerant 6 V charging capability.

For engineers reviewing the TUSB6015IZQE datasheet, TUSB6015IZQE pinout, TUSB6015IZQE application, or TUSB6015IZQE equivalent, this device is selected for embedded host-peripheral bridging where low-latency NOR-interface access, USB-IF certified HS compliance (TID #40630005), and multi-rail power management (1.5 V / 1.8 V / 3.3 V) are required.

Technical Context

The TUSB6015IZQE implements a dedicated USB 2.0 HS peripheral core with fully integrated analog/digital PHY, eliminating external transceivers. Its NOR Flash–like interface uses multiplexed ADAT[0:16], ADVn, ACSn, SCSn, OEn, WEn, and RDY signals to support both asynchronous single-access and synchronous burst modes with programmable wait states.

Power sequencing is strictly defined across five supply domains: VDD15 (1.5 V digital core), VDD18 (1.8 V I/O), VDDA1P5/VDDD1P5/VDDCM1P5 (1.5 V PHY analog/digital/common), and VDDA3P3 (3.3 V PHY analog), each requiring dedicated decoupling and isolation per TI layout guidelines.

FAQ

What is the USB compliance status of the TUSB6015IZQE?

The TUSB6015IZQE is fully compliant with the Universal Serial Bus Specification Revision 2.0 and holds USB-IF certification with Test ID #40630005. It supports High-Speed (480 Mbps), Full-Speed (12 Mbps), and Low-Speed (1.5 Mbps) modes, including chirp K/J detection, SE0 signaling, and HS idle/squelch thresholds per specification. The TUSB6015IZQE integrates all required PHY functions and passes electrical compliance testing per Chapter 7.1.1 of the USB 2.0 spec.

Does the TUSB6015IZQE require an external crystal or oscillator?

No, the TUSB6015IZQE does not require an external crystal. It accepts two reference clock options: 19.2 MHz square wave (when GPIO6 = high at reset) or 38.4 MHz sinusoid (when GPIO6 = low at reset). Both clocks must meet specified jitter (≤118 ps peak-to-peak), rise/fall time (≤5 ns), and accuracy (±100 ppm) requirements. The internal PLL synthesizes the 480 MHz HS clock from either input.

How many endpoints does the TUSB6015IZQE support, and how are they configured?

The TUSB6015IZQE supports six physical endpoints, each with a dedicated 1 KB buffer. Each endpoint is software-configurable as IN or OUT direction via control registers accessible through the NOR Flash–like interface. Endpoint types (control, bulk, interrupt, isochronous) are assigned dynamically during USB descriptor setup. No hardware reconfiguration is needed-the TUSB6015IZQE handles all endpoint arbitration and FIFO management internally.

What are the power supply requirements for the TUSB6015IZQE?

The TUSB6015IZQE requires five distinct supply rails: VDD15 (1.35–1.65 V, digital core), VDD18 (1.62–1.98 V, I/O), VDDA1P5/VDDD1P5/VDDCM1P5 (1.35–1.65 V, PHY analog/digital/common), and VDDA3P3 (3.0–3.6 V, PHY analog). Each rail has dedicated ground pins (VSS, VSSA1P5, VSSCM1P5, etc.) and specific decoupling requirements-including series inductors on analog supplies-to ensure USB HS signal integrity and EMI compliance.

Is the TUSB6015IZQE pin-compatible with other devices in the TUSB60xx family?

The TUSB6015IZQE shares the same 80-ball ZQE BGA package and pinout with the TUSB6020IZQE, enabling mechanical compatibility. However, TUSB6020IZQE omits support for 32-bit NOR burst access and reduces endpoint count to four. Other variants (e.g., TUSB6010) use different packages and are not pin-compatible. Always verify register map and feature enablement-pin compatibility does not guarantee full functional equivalence for the TUSB6015IZQE.
