Product details
Overview
SST26VF064B-104V/SO from Microchip Technology is a 64-Mbit Serial Quad I/O™ (SQI™) Flash memory IC designed for high-speed, low-power embedded code storage and data logging. It operates at 104 MHz (2.7–3.6 V), supports x1/x2/x4 SPI protocols and SQI mode, features uniform 4-Kbyte sectors, and delivers 100,000 program/erase cycles with >100-year data retention in industrial temperature range (–40°C to +85°C).
For engineers reviewing the SST26VF064B-104V/SO datasheet, SST26VF064B-104V/SO pinout, SST26VF064B-104V/SO application, or SST26VF064B-104V/SO equivalent, key selection considerations include its SOIJ-8 package compatibility, dual-mode SPI/SQI interface flexibility, hardware write protection via WP# pin, burst read capability, and OTP Security ID for device authentication.
Technical Context
The SST26VF064B-104V/SO implements Microchip's proprietary SuperFlash® technology with split-gate cells and thick-oxide tunneling, enabling faster erase (sector/blk: 18 ms typ.) and lower energy per operation versus conventional NOR Flash. Its dual-mode interface supports legacy SPI (Mode 0/3) and high-throughput SQI protocol using SIO[3:0] multiplexed I/Os.
It integrates configurable protection mechanisms: volatile Write Protection Lock-Down (WPLD), nonvolatile Write Lock Lock-Down (nVWLDR), and individual block protection with read/write lock bits for eight 8-Kbyte parameter blocks and overlay blocks. The IOC bit in the Configuration register determines whether WP#/HOLD# or SIO2/SIO3 are active at power-up - SST26VF064B defaults to IOC=0 (WP#/HOLD# enabled).
Key Specifications

Pinout & Package
Package: 8-lead SOIJ (5.28 mm width), RoHS-compliant, surface-mount.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 CE# | Chip Enable | Active-low enable for serial command execution; must remain low during full instruction sequence |
| 2 SO/SIO1 | Serial Output / Quad I/O 1 | Default SPI output (SO); becomes bidirectional SIO1 in SQI mode after IOC=1 configuration |
| 3 WP#/SIO2 | Write Protect Input / Quad I/O 2 | In SPI mode (IOC=0): hardware write lock for Block Protection register; in SQI mode (IOC=1): bidirectional SIO2 |
| 4 VSS | Ground | Reference return path for all internal circuitry and I/O signals |
| 5 VDD | Power Supply | 2.3–3.6 V supply input; decoupling capacitor required near pin for stable operation |
| 6 HOLD#/SIO3 | Hold Input / Quad I/O 3 | In SPI mode (IOC=0): pauses ongoing serial transfer without reset; in SQI mode (IOC=1): bidirectional SIO3 |
| 7 SCK | Serial Clock | Timing reference for all serial transfers; supports Mode 0 (SCK idle low) and Mode 3 (SCK idle high) |
| 8 SI/SIO0 | Serial Input / Quad I/O 0 | Default SPI input (SI); becomes bidirectional SIO0 in SQI mode after IOC=1 configuration |
Key Features
| Feature | Design Value |
|---|---|
| Quad I/O Interface | Enables 4-bit parallel data transfer on SIO[3:0], quadrupling throughput vs. standard SPI at same clock frequency |
| Flexible Erase Architecture | Uniform 4-Kbyte sectors plus dedicated 8-Kbyte/32-Kbyte/64-Kbyte overlay blocks - supports partial firmware updates without full chip erase |
| Write Suspend | Allows suspension of active Program or Erase operations to service urgent read requests - improves real-time system responsiveness |
| Hardware + Software Protection | WP# pin + IOC-configurable protection registers + nonvolatile lock-down bits - prevents accidental or malicious memory corruption |
| Burst Read Modes | Continuous linear and wrap-around bursts (8/16/32/64-byte) - optimizes sequential code fetch and streaming data access |
Applications
| Boot Code Storage | Firmware Update Storage |
|---|---|
Use Scenario: Storing primary bootloader and application firmware executed directly from Flash by microcontroller on power-up. IC Role / Device Role / Timing Role: Nonvolatile code storage with fast random-access read and deterministic timing for XIP-capable systems. Use Value: 104 MHz SPI/SQI interface ensures low-latency instruction fetch; uniform sector layout simplifies OTA update partitioning. | Use Scenario: Holding staged firmware images for over-the-air (OTA) or field-upgrade deployment in connected edge devices. IC Role / Device Role / Timing Role: Dual-bank capable storage with independent block protection - allows safe background download while running current firmware. Use Value: Write suspend and fast sector erase (18 ms) minimize downtime during update; OTP Security ID validates image authenticity pre-execution. |
| Data Logging Buffer | Secure Device Identity |

IC Role / Device Role / Timing Role: High-endurance, low-voltage write-capable memory with atomic page programming (256-byte pages). Use Value: 100,000-cycle endurance and >100-year retention ensure reliable long-term logging; burst modes accelerate bulk data writes. | Use Scenario: Embedding immutable device identity in medical, automotive, or IoT endpoints requiring traceability and anti-cloning. IC Role / Device Role / Timing Role: Secure storage for cryptographic keys and unique identifiers using factory-programmed and user-lockable OTP space. Use Value: 64-bit factory-preprogrammed ID + 2-Kbyte user-programmable OTP area enables hardware-rooted trust; LSID command permanently locks contents. |
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 W25Q64JVSSIQ | 64 Mbit, 133 MHz max, standard SPI only (no SQI), 4-Kbyte sectors, 100K cycles | Lacks Quad I/O interface and SQI burst modes; no OTP Security ID or nVWLDR lock-down | Preferred when SQI bandwidth is unnecessary and cost-sensitive SPI-only designs dominate |
| Cypress S25FL164K0XMFI010 | 64 Mbit, 85 MHz max, supports both SPI and QPI modes, 4-Kbyte sectors, 100K cycles | QPI mode differs from SQI signaling; no integrated Security ID; different hold/protect pin behavior | Selected for legacy Cypress ecosystem integration or where QPI timing model aligns better with host controller |
Compared with SST26VF064B-104V/SO, W25Q64JVSSIQ offers higher clock speed but lacks SQI throughput and security features, while S25FL164K0XMFI010 provides QPI compatibility but omits OTP-based device identity - SST26VF064B-104V/SO uniquely balances high-speed quad interface, robust protection, and hardware-enforced identity in SOIJ-8.

FAQ
What interface modes does the SST26VF064B-104V/SO support?
The SST26VF064B-104V/SO supports both traditional SPI (x1/x2 modes, Mode 0/3) and Serial Quad I/O™ (SQI) protocol using SIO[3:0]. At power-up, SST26VF064B defaults to IOC=0, enabling WP# and HOLD# pins for SPI operation. SQI mode requires issuing the EQIO command and setting IOC=1. All interface modes operate up to 104 MHz under 2.7–3.6 V.
How does the SST26VF064B-104V/SO handle write protection?
The SST26VF064B-104V/SO implements three-tiered write protection: (1) hardware via WP# pin (enabled when IOC=0 and WPEN=1), (2) volatile lock-down of the Block Protection register (WPLD bit), and (3) nonvolatile lock-down via nVWLDR bits. Once any nVWLDR bit is set to '1', the corresponding block protection bit is permanently fixed - this irreversible mechanism secures critical firmware partitions in SST26VF064B-104V/SO deployments.
What is the purpose of the Security ID feature in the SST26VF064B-104V/SO?
The SST26VF064B-104V/SO includes a 2-Kbyte Security ID (Sec ID) space comprising a factory-programmed 64-bit unique identifier and a user-programmable segment. The factory ID is immutable and enables device-level traceability; the user area supports cryptographic key storage. The LSID command permanently locks the entire Sec ID space, preventing further writes - a critical capability for secure boot validation in SST26VF064B-104V/SO-based systems.
Can the SST26VF064B-104V/SO be used in automotive applications?
Yes - the SST26VF064B-104V/SO is qualified to AEC-Q100 Grade 2 (–40°C to +105°C) and Grade 3 (–40°C to +125°C), making it suitable for automotive infotainment, ADAS logging, and body control modules. Its SuperFlash® technology ensures robustness against thermal stress and voltage transients, while the 100,000-cycle endurance supports frequent firmware updates required in modern vehicle platforms using SST26VF064B-104V/SO.
What package options are available for the SST26VF064B-104V/SO?
The SST26VF064B-104V/SO is specifically offered in the 8-lead SOIJ (Small Outline J-bend) package, 5.28 mm wide, with lead-free and RoHS-compliant construction. While the broader SST26VF064B family includes 16-lead SOIC, 24-ball TBGA, and WDFN variants, the -104V/SO suffix explicitly denotes the SOIJ-8 configuration - verified in Microchip's DS20005119K datasheet pin assignment diagrams and ordering information.
