Product details
Overview
USBF1600-I/SNVAO 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, and operates across -40°C to +85°C for infotainment head units and multi-row USB media hubs.
For engineers reviewing the USBF1600-I/SNVAO datasheet, USBF1600-I/SNVAO pinout, USBF1600-I/SNVAO application, or USBF1600-I/SNVAO equivalent, this page delivers verified technical context, industrial-grade reliability specs (100,000 write cycles, >100-year data retention), package-validated pin functions, and real-world USB hub firmware deployment guidance.
Technical Context
The USBF1600-I/SNVAO 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 - enabling up to 4× bandwidth vs. standard SPI at identical clock rates. Its split-gate SuperFlash technology ensures robust endurance and data retention without external ECC.
Memory organization includes uniform 4 KByte sectors plus configurable overlay blocks: eight 8 KByte, two 32 KByte, and thirty 64 KByte blocks - optimized for firmware partitioning, parameter storage, and secure boot code separation in USB host controller systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 2 MByte (16 Mbit) - sufficient for full USB491X firmware image plus configuration and security ID storage |
| Max Clock Frequency | 104 MHz - enables high-throughput firmware loading and runtime updates in USB 2.0 High-Speed systems |
| Endurance | 100,000 program/erase cycles - supports field firmware upgrades over vehicle lifetime |
| Data Retention | >100 years - guarantees firmware integrity across automotive service life without refresh |
| Operating Voltage | 2.7–3.6 V - compatible with standard automotive 3.3 V rail and brown-out tolerant power domains |
| Temperature Range | -40°C to +85°C (Industrial) - validated for under-dash infotainment environments |
| Active Read Current | 15 mA typical @ 104 MHz - low dynamic power enables thermal-safe integration near USB PHYs |
| Standby Current | 15 µA typical - minimizes quiescent drain during USB suspend states |
Pinout & Package
USBF1600-I/SNVAO is packaged in an 8-lead SOIC (3.90 mm body, SN suffix), with lead pitch 1.27 mm and JEDEC-standard pinout. Pin functions are electrically identical to the WDFN variant but mapped to gull-wing leads for through-hole or surface-mount assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 CE# | Chip Enable | Active-low selection signal; must remain asserted throughout command/data sequences to prevent premature termination |
| 2 SO/SIO1 | Serial Output / Quad I/O 1 | Default SPI output pin; reconfigured as bidirectional SIO1 in SQI mode after EQIO command |
| 3 WP#/SIO2 | Write Protect / Quad I/O 2 | Hardware write lock for block-protection register; dual-role pin enabled only when IOC bit = 1 |
| 4 VSS | Ground | Reference return path for all digital and power circuits; requires low-inductance PCB connection |
| 5 VDD | Power Supply | 2.7–3.6 V supply input; decoupling capacitor (≥100 nF) required within 5 mm of pin |
| 6 HOLD#/SIO3 | Hold / Quad I/O 3 | Suspends ongoing read/write to allow priority access; functional only in SPI single/dual mode unless disabled via configuration |
| 7 SCK | Serial Clock | Edge-triggered timing reference; rising edge latches inputs, falling edge outputs data - supports Mode 0 and Mode 3 |
| 8 SI/SIO0 | Serial Input / Quad I/O 0 | Default SPI input pin; becomes bidirectional SIO0 in SQI mode; critical for command/address/data ingress |
Key Features
| Feature | Design Value |
|---|---|
| Quad I/O (SQI) Interface | Enables 4× throughput vs. SPI at same clock rate - reduces firmware load time by up to 75% in USB491X boot sequences |
| Flexible Block Protection | Independent lock-down of 64 KByte, 32 KByte, and 8 KByte blocks - isolates bootloader, config, and user firmware regions |
| One-Time Programmable Security ID | 64-bit factory pre-programmed + 2 KByte user-programmable OTP area - supports device authentication and anti-cloning |
| Write-Suspend Capability | Allows interruption of erase/program to service urgent reads - essential for real-time USB descriptor fetches during firmware update |
| Deep Power-Down Mode | 8 µA typical current draw - extends system-level sleep efficiency in always-on infotainment gateways |
| AEC-Q100 Qualified | Grade 2 (-40°C to +105°C) and Grade 3 (-40°C to +85°C) compliance - certified for automotive USB hub applications |

FAQ
What is the primary function of the USBF1600-I/SNVAO in a USB491X-based system?
The USBF1600-I/SNVAO serves as the dedicated firmware memory for Microchip's USB491X USB Smart Hub controllers. It stores boot code, USB descriptors, configuration parameters, and security credentials - enabling rapid, reliable initialization and runtime operation of automotive infotainment USB hubs without external firmware loading circuitry.
Does the USBF1600-I/SNVAO support both SPI and SQI protocols, and how is mode selection handled?
Yes, USBF1600-I/SNVAO supports both standard SPI (x1/x2 modes) and Serial Quad I/O (SQI) protocol. It powers up in SPI mode by default; the Enable Quad I/O (EQIO) command (0x38) configures SIO[3:0] pins for quad operation. The IOC bit in the Configuration Register must be set to '1' before issuing SQI commands.
What packaging options are available for the USBF1600-I/SNVAO, and what does the 'SN' suffix indicate?
The USBF1600-I/SNVAO uses the 8-lead SOIC (Small Outline Integrated Circuit) package with 3.90 mm body width, denoted by the 'SN' suffix. This gull-wing leaded package supports reflow and wave soldering, and is pin-compatible with industry-standard SOIC-8 footprints used in automotive PCB assemblies.
How is security implemented in the USBF1600-I/SNVAO, and what role does the Security ID play?
Security in USBF1600-I/SNVAO includes a factory-programmed 64-bit unique identifier and a 2 KByte One-Time Programmable (OTP) area for user keys. The RSID (0x88) and PSID (0xA5) commands enable read and programming of this region. The Security ID anchors cryptographic verification of USB491X firmware, preventing unauthorized firmware replacement.
Is the USBF1600-I/SNVAO qualified for automotive applications, and which AEC-Q100 grades does it meet?
Yes, USBF1600-I/SNVAO is AEC-Q100 qualified for automotive use. It meets Grade 2 (-40°C to +105°C) and Grade 3 (-40°C to +85°C) requirements, including stress testing for temperature cycling, humidity, and mechanical shock - validating its suitability for under-dash infotainment and USB hub modules.
