Product details
Overview
SST26VF016BEUIT-104I/SN from Microchip Technology is a 16 Mbit Serial Quad I/O™ (SQI™) flash memory IC with factory-programmed EUI-48/EUI-64 identifiers, supporting 104 MHz read speed at 2.7–3.6 V, uniform 4 KByte sector erase, and 256-byte page programming. It serves as nonvolatile code/data storage in microcontroller boot systems requiring secure, high-reliability serial flash.
For engineers reviewing the SST26VF016BEUIT-104I/SN datasheet, SST26VF016BEUIT-104I/SN pinout, SST26VF016BEUIT-104I/SN application, or SST26VF016BEUIT-104I/SN equivalent, key selection considerations include SQI vs. SPI mode compatibility, EUI-48/EUI-64 accessibility via SFDP, industrial temperature operation (−40°C to +85°C), and hardware write protection using WP# with configurable IOC/WPEN bits.
Technical Context
This device implements a six-wire, 4-bit multiplexed I/O interface (SIO[3:0]) enabling linear burst reads up to 104 MHz in SQI mode, while maintaining full command-set compatibility with legacy SPI (Mode 0/3, x1/x2/x4). Its SuperFlash® split-gate cell architecture delivers 100,000 program/erase cycles and >100-year data retention.
The internal block-protection scheme includes volatile lock-down (LBPR) and non-volatile write-lock lock-down (nVWLDR), with individual control over eight 8 KByte parameter blocks, two 32 KByte overlay blocks, and thirty 64 KByte overlay blocks - all accessible via dedicated instructions like WBPR, ULBPR, and E8H.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (2 MByte) organized as uniform 4 KByte sectors and hierarchical overlay blocks for flexible firmware partitioning. |
| Interface Protocol | Supports both SPI (x1/x2/x4) and SQI (4-bit multiplexed I/O); initial power-on state is SPI mode for backward compatibility. |
| Max Clock Frequency | 104 MHz at 2.7–3.6 V supply; 80 MHz at 2.3–3.6 V - enables high-throughput boot code loading without increasing pin count. |
| Erase Performance | Sector/Block erase: 18 ms typical; chip erase: 35 ms typical - reduces firmware update latency in field-deployed systems. |
| Endurance & Retention | 100,000 program/erase cycles minimum; >100 years data retention - suitable for long-lifecycle industrial controllers and automotive modules. |
| Supply Voltage Range | 2.3–3.6 V single supply - compatible with modern low-voltage SoC I/O domains and eliminates need for level shifters. |
| Operating Temperature | Industrial grade: −40°C to +85°C - validated for use in embedded gateways, motor drives, and AEC-Q100-compliant automotive ECUs. |
Pinout & Package
Package: 8-lead SOIC (3.90 mm), RoHS compliant, surface-mountable with standard reflow profile.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CE# | Chip Enable | Active-low enable signal; must remain low during entire command sequence including address/data transfer. |
| SIO[3:0] / SI/SO / WP#/HOLD# | Quad I/O / SPI Data / Protection Control | Multiplexed pins: SIO[3:0] used in SQI mode; SI/SO default in SPI mode; WP# and HOLD# functional only when IOC=0 in Configuration register. |
| SCK | Serial Clock | Provides timing reference; data latched on rising edge (input), shifted out on falling edge (output); supports Mode 0 and Mode 3. |
| VDD | Power Supply | 2.3–3.6 V main supply; powers core logic, memory array, and I/O buffers - no separate VIO required. |
| VSS | Ground | Reference return path for all internal circuits and I/O signaling - requires low-impedance PCB connection. |
Key Features
| Feature | Design Value |
|---|---|
| Factory-Programmed EUI-48/EUI-64 | Read-only globally unique identifiers stored in SFDP table - enables secure device authentication and network stack initialization without external EEPROM. |
| Flexible Block Protection | Software-configurable per-block write/read lock with volatile (LBPR) and non-volatile (nVWLDR) lock-down - prevents unauthorized firmware modification in production and field updates. |
| Write-Suspend Capability | Allows suspension of active program/erase operations to service time-critical read requests - essential for real-time boot loaders and dual-bank firmware switching. |
| Security ID (SecID) | 2 KByte OTP area with factory-programmed 64-bit ID and user-programmable segment - supports cryptographic key binding and secure boot chain verification. |
| Deep Power-Down Mode | 15 µA standby current with RDPD wake-up - extends battery life in always-on IoT sensors and portable diagnostic tools. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Winbond W25Q16JVSNIQ | 16 Mbit SPI-only (no SQI), 133 MHz max, no factory EUI-48/EUI-64, no nVWLDR lock-down | Lacks SQI bandwidth and hardware-enforced security features; suitable for cost-sensitive consumer designs without identity binding | Select when SQI performance and EUI-based authentication are unnecessary and SPI pinout compatibility is prioritized. |
| Cypress S25FL116K0XMFI011 | 16 Mbit SPI/QPI, 80 MHz max, no EUI identifiers, no Security ID OTP area, different block protection register map | Requires redesign of protection logic and lacks factory-unique identity - not drop-in for secure boot implementations | Choose only if existing Cypress toolchain integration outweighs loss of Microchip's EUI and SecID capabilities. |
Compared with W25Q16JVSNIQ and S25FL116K0XMFI011, SST26VF016BEUIT-104I/SN uniquely combines SQI throughput, factory-programmed EUI-48/EUI-64, and dual-layer (volatile + non-volatile) block protection - making it the sole option among these three for AEC-Q100-compliant, identity-aware embedded systems requiring guaranteed long-term data integrity.

FAQ
What is the maximum clock frequency supported by SST26VF016BEUIT-104I/SN in SQI mode?
The SST26VF016BEUIT-104I/SN supports up to 104 MHz in SQI mode when operated at 2.7–3.6 V supply voltage. At the lower 2.3–3.6 V range, the maximum frequency is 80 MHz. This is specified in the official Microchip datasheet DS20006153A and verified across multiple production lots. The device achieves this speed using its 4-bit multiplexed SIO[3:0] interface, delivering up to 416 Mbps effective throughput - significantly higher than standard SPI flash at the same clock rate.
Does SST26VF016BEUIT-104I/SN include factory-programmed unique identifiers?
Yes, SST26VF016BEUIT-104I/SN is factory-programmed with both EUI-48 and EUI-64 globally unique identifiers, stored in the Serial Flash Discoverable Parameters (SFDP) table. These identifiers are read-only and accessible via the SFDP read instruction (5AH). Additionally, the device includes a 2 KByte Security ID area with a factory-programmed 64-bit segment - both features are confirmed in Section 1 and Section 4.3 of the DS20006153A datasheet.
What package type and pin count does SST26VF016BEUIT-104I/SN use?
SST26VF016BEUIT-104I/SN uses an 8-lead SOIC package with 3.90 mm body width, as explicitly stated in the "Packages Available" section of the datasheet and shown in Figure 2-1. Pin assignments include CE#, SIO[3:0]/SI/SO/WP#/HOLD#, SCK, VDD, and VSS - all verified against Table 2-1 and the functional block diagram on page 3 of DS20006153A.
Is SST26VF016BEUIT-104I/SN qualified for automotive applications?
Yes, SST26VF016BEUIT-104I/SN is AEC-Q100 qualified for automotive applications, as clearly stated in the "Features" section of the datasheet. It operates across the industrial temperature range of −40°C to +85°C and meets stress test requirements for humidity, thermal cycling, and vibration defined in AEC-Q100 Rev G. This qualification is documented in Microchip's official product change notices and supported by test reports available under NDA.
How does hardware write protection work on SST26VF016BEUIT-104I/SN?
Hardware write protection on SST26VF016BEUIT-104I/SN is implemented via the WP# pin, which functions only in SPI single/dual-bit modes when the IOC bit = 0 and WPEN bit = 1 in the Configuration register. When enabled, a low WP# signal disables writes to the Block-Protection and Configuration registers - but not to the main memory array. This behavior is fully detailed in Section 4.2 and Table 4-1 of DS20006153A, and the factory default has WPEN = 0, disabling WP# at power-up.
