Product details
Overview
USBF1600T-I/MFVAO from Microchip Technology is a USB firmware memory IC designed as a dedicated companion to the USB491X family of automotive USB Smart Hub controllers. It provides 2 MByte (16 Mbit) of serial flash storage, supports x1/x2/x4 SPI and SQI protocols up to 104 MHz, operates from 2.7–3.6 V, and delivers 15 mA typical active read current at full speed - enabling fast, reliable firmware loading in infotainment head units and multi-row USB media hubs.
For engineers reviewing the USBF1600T-I/MFVAO datasheet, USBF1600T-I/MFVAO pinout, USBF1600T-I/MFVAO application, or USBF1600T-I/MFVAO equivalent, this page delivers verified technical context, validated pin functions, real-world timing and endurance specs (100,000 cycles / >100 years retention), and AEC-Q100 Grade 2 qualified operation for automotive USB 2.0 High-Speed systems.
Technical Context
The USBF1600T-I/MFVAO implements a six-wire, 4-bit I/O interface supporting both legacy SPI (Mode 0/3) and high-speed Serial Quad I/O (SQI) protocols - with quad-mode enabled via EQIO command. Its SuperFlash technology uses split-gate cells and thick-oxide tunneling for enhanced reliability over standard NOR flash.
Memory organization includes uniform 4 KByte sectors plus flexible overlay blocks: eight 8 KByte, two 32 KByte, and thirty 64 KByte erasable blocks. Write-suspend capability allows interruption of program/erase operations to access other memory regions without data loss.

FAQ
What is the primary function of the USBF1600T-I/MFVAO in a USB491X-based system?
The USBF1600T-I/MFVAO serves as the dedicated firmware memory for Microchip's USB491X USB Smart Hub controllers. It stores executable firmware, configuration parameters, and security identifiers required for USB enumeration, power delivery negotiation, and hub port management - eliminating the need for external firmware loading circuitry and reducing boot time in automotive infotainment systems.
Does the USBF1600T-I/MFVAO support both SPI and SQI interfaces, and how are they configured?
Yes, USBF1600T-I/MFVAO powers up in SPI mode (x1/x2/x4) and can be switched to Serial Quad I/O (SQI) mode using the EQIO command. In SQI mode, pins SI/SIO0 through HOLD#/SIO3 become bidirectional I/O lines, enabling four-bit parallel data transfer and quadrupling effective bandwidth at the same clock frequency - critical for high-speed firmware reads during USB initialization.
What AEC-Q100 qualification level does the USBF1600T-I/MFVAO meet, and what temperature range does it cover?
USBF1600T-I/MFVAO is qualified to AEC-Q100 Grade 2, covering an operating ambient temperature range of –40°C to +105°C. This certification validates its reliability for under-hood and dashboard-mounted USB hub applications where thermal stress and long-term stability are critical design constraints.
How is the 64-bit Security ID implemented in the USBF1600T-I/MFVAO, and can it be reprogrammed?
The USBF1600T-I/MFVAO includes a 2 KByte One-Time Programmable (OTP) Security ID area containing a 64-bit factory-preprogrammed unique identifier. Users may program additional data into the user-programmable portion via PSID command, but the factory ID itself is immutable - ensuring device authenticity and enabling cryptographic binding of firmware images to specific hardware units.
What package type does the USBF1600T-I/MFVAO use, and what are its key mechanical dimensions?
USBF1600T-I/MFVAO uses an 8-contact WDFN package (6.00 mm × 5.00 mm body, MF suffix) with an exposed thermal pad. Per Microchip Drawing C04-210B, it has 0.50 mm terminal width, 0.70 mm overall height, and 1.27 mm pitch - optimized for compact automotive PCB layouts while maintaining thermal performance and solder joint reliability.
