Product details
Overview
USBF1600-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) serial flash storage with x1/x2/x4 SPI and SQI interfaces, 104 MHz max clock frequency, industrial temperature range (–40°C to +85°C), and AEC-Q100 Grade 2 qualification for infotainment head units and multi-row USB media hubs.
For engineers reviewing the USBF1600-I/MFVAO datasheet, USBF1600-I/MFVAO pinout, USBF1600-I/MFVAO application, or USBF1600-I/MFVAO equivalent, key selection considerations include its 8-lead WDFN (6 mm × 5 mm) package, quad I/O support for high-speed firmware loading, block-level write protection with OTP Security ID, and guaranteed 100,000 erase/program cycles with >100-year data retention.
Technical Context
The USBF1600-I/MFVAO implements a six-wire, 4-bit multiplexed Serial Quad I/O (SQI) interface alongside backward-compatible SPI modes (x1/x2/x4), enabling up to 4× bandwidth over standard SPI at 104 MHz. Its memory array is organized into uniform 4 KByte sectors and mixed overlay blocks (eight 8 KByte, two 32 KByte, thirty 64 KByte), supporting flexible firmware partitioning for USB hub configuration, parameter storage, and secure boot code.
It uses Microchip's proprietary SuperFlash technology with split-gate cells and thick-oxide tunneling injectors, delivering superior endurance and data retention versus conventional NOR flash. The device supports software reset, write-suspend/resume, deep power-down (8 µA typical), and hardware-assisted security via factory-programmed 64-bit unique ID and user-programmable 2 KByte OTP Secure ID area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory size | 2 MByte (16 Mbit) - sufficient for full USB491X firmware image plus overlay parameters and secure boot assets. |
| Max clock frequency | 104 MHz - enables high-speed firmware load during USB enumeration without system boot delay. |
| Endurance | 100,000 cycles (min) - supports field firmware updates across vehicle lifetime in automotive infotainment systems. |
| Data retention | >100 years - ensures persistent storage of calibration, configuration, and security keys over product lifecycle. |

Pinout & Package
USBF1600-I/MFVAO is packaged in an 8-contact WDFN (6 mm × 5 mm) with wettable flank leads, optimized for automotive reflow and automated optical inspection. Pin 1 is marked by a hatched corner on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CE# | Chip Enable | Active-low enable signal; must remain asserted throughout command/data sequences to prevent bus timeout or corruption. |
| SIO0/SI | Serial Data Input | Default SPI input pin; latches commands/addresses/data on rising SCK edge; transitions to bidirectional SIO[3:0] in SQI mode. |
| SIO1/SO | Serial Data Output | Default SPI output pin; shifts data out on falling SCK edge; shares function with SIO[3:0] in SQI mode. |
| SIO2/WP# | Write Protect / Input | Hardware write-protection control for block-protection register; functional only in SPI single/dual-bit read modes. |
| SIO3/HOLD# | Hold / Input | Pauses ongoing serial transfers without deselecting device; must be tied high if unused to avoid unintended hold state. |
| SCK | Serial Clock | Master-generated timing reference; rising edge clocks inputs, falling edge clocks outputs; supports Mode 0 and Mode 3. |
| VDD | Power Supply | Primary 2.7–3.6 V supply; requires stable ramp rate (>1 V/100 ms) for reliable power-up initialization. |
| VSS | Ground | Reference return path for all I/O and core logic; must be low-impedance and decoupled near package. |
Key Features
| Feature | Design Value |
|---|---|
| Quad I/O (SQI) interface | Enables 4× throughput vs. standard SPI at same clock frequency-critical for fast USB hub firmware load during enumeration. |

FAQ
What is the primary function of the USBF1600-I/MFVAO in a USB491X-based system?
The USBF1600-I/MFVAO serves as the dedicated firmware memory for Microchip's USB491X USB Smart Hub controllers. It stores the controller's microcode, device descriptors, configuration parameters, and secure boot assets-enabling rapid, reliable enumeration and operation without external memory management. Its architecture is optimized for USB hub use cases, including parameter overlay blocks and OTP security ID integration.
Does the USBF1600-I/MFVAO support both SPI and SQI protocols, and how do they differ in practice?
Yes, USBF1600-I/MFVAO supports both legacy SPI (x1/x2/x4) and Serial Quad I/O (SQI) protocols. After power-on reset, it defaults to SPI mode for backward compatibility. The EQIO command enables SQI mode, where SIO[3:0] pins operate bidirectionally for command, address, and data-quadrupling effective throughput at the same 104 MHz clock frequency. This reduces firmware load time significantly in USB491X systems.
What AEC-Q100 qualification level does the USBF1600-I/MFVAO meet, and what does that mean for automotive deployment?
The USBF1600-I/MFVAO is qualified to AEC-Q100 Grade 2, specifying operation from –40°C to +105°C ambient temperature with full reliability testing (HTOL, ESD, TC, etc.). This certification validates its suitability for under-dash automotive environments such as infotainment head units and central USB media hubs-where thermal stress, vibration, and long operational lifetimes are critical design constraints.
How is security implemented in the USBF1600-I/MFVAO, and can the Security ID be reprogrammed?
Security in USBF1600-I/MFVAO includes factory-programmed 64-bit unique identifier, user-programmable 2 KByte OTP Secure ID area, and hardware-enforced block protection with permanent lock-down. The factory ID is immutable; the OTP area allows one-time programming of custom keys or certificates. Once locked, the Security ID cannot be altered-ensuring cryptographic binding between firmware and hardware identity in automotive USB systems.
What package type does the USBF1600-I/MFVAO use, and why is it suitable for automotive PCB assembly?
USBF1600-I/MFVAO uses an 8-lead WDFN package (6 mm × 5 mm body, MF suffix) with wettable flank leads. This package supports automated optical inspection (AOI) of solder joints, withstands automotive reflow profiles (including lead-free 260°C peak), and provides excellent thermal performance and board-level reliability-making it ideal for high-volume automotive electronics manufacturing where zero-defect yield is mandatory.
