Product details
Overview
SST26VF064BT-104I/TD from Microchip Technology is a 64-Mbit Serial Quad I/O™ (SQI™) Flash memory IC operating at up to 104 MHz (2.7V–3.6V), organized in uniform 4-Kbyte sectors with flexible block protection, 100,000 write/erase endurance, and industrial temperature range (–40°C to +85°C). It serves as nonvolatile program/data storage in microcontroller boot loaders, firmware update buffers, and embedded system configuration memory.
For engineers reviewing the SST26VF064BT-104I/TD datasheet, SST26VF064BT-104I/TD pinout, SST26VF064BT-104I/TD application, or SST26VF064BT-104I/TD equivalent, key selection criteria include quad-mode timing compatibility, sector-level erase granularity, hardware write-protection pin behavior, and Security ID OTP capability.
Technical Context
The SST26VF064BT-104I/TD implements a six-wire SQI interface (SCK, CE#, WP#, HOLD#, VDD, VSS, SIO[3:0]) supporting both SPI Mode 0/3 and x1/x2/x4 protocols. Its SuperFlash® split-gate cell enables 18 ms typical sector erase and 256-byte page programming with software polling via BUSY bit in STATUS register.
It features dual-configurable I/O: default SPI mode (WP#/HOLD# enabled, SIO2/SIO3 disabled) on power-up, configurable to Quad I/O via EQIO command and IOC bit setting. Protection includes volatile lock-down (WPLD), nonvolatile write-lock lock-down (nVWLDR), and factory-programmed 64-bit unique Security ID with user-programmable 2-Kbyte area.

Applications
| Boot Code Storage | Firmware Update Buffer |
|---|---|
Use Scenario: Stores MCU boot loader and initial application code executed on power-up. IC Role / Device Role / Timing Role: Nonvolatile storage mapped to processor's XIP or serial flash interface; accessed during cold start and reset recovery. Use Value: 104 MHz Quad I/O read speed reduces boot latency; 4-Kbyte sector erase enables safe in-field bootloader updates without erasing application code. | Use Scenario: Holds validated firmware images prior to atomic swap into main execution space. IC Role / Device Role / Timing Role: Secondary storage partition used during over-the-air (OTA) update workflows, isolated from active runtime memory. Use Value: Write suspend allows concurrent status reads during long erase/program operations; Security ID prevents unauthorized image injection. |
| Configuration Parameter Storage | Industrial Sensor Calibration Data |
Use Scenario: Retains user-defined settings (network IDs, thresholds, calibration offsets) across power cycles. IC Role / Device Role / Timing Role: Persistent parameter bank accessed via SPI during initialization or runtime reconfiguration. Use Value: Individual 8-Kbyte block protection prevents accidental overwrite of critical settings; >100-year data retention ensures lifetime validity in unattended deployments. | Use Scenario: Stores factory-calibrated sensor coefficients and compensation tables for precision analog front-ends. IC Role / Device Role / Timing Role: Read-only data repository loaded once at manufacturing and accessed during sensor signal processing. Use Value: Factory-programmed 64-bit Security ID binds calibration data to specific hardware unit; OTP lock prevents tampering post-calibration. |
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 W25Q64JW | 64-Mbit, 133 MHz max, 1.65V–3.6V supply, no built-in Security ID OTP | Lacks factory-unique identifier and dedicated Sec ID lock; requires external security layer for authentication | Preferred where higher clock speed and wider voltage range outweigh security requirements |
| Cypress S25FL164K | 64-Mbit, 85 MHz max, 2.7V–3.6V, supports SFDP but no Quad I/O burst wrap mode | No RBSPI/RBSQI instructions; lacks write suspend and nVWLDR permanent lock-down | Selected when legacy SPI compatibility and simpler protection model suffice |
Compared with W25Q64JW and S25FL164K, the SST26VF064BT-104I/TD provides superior security integration via OTP Security ID, deterministic write suspend for real-time systems, and optimized burst wrap modes for streaming firmware loads-making it optimal for safety-critical and authenticated embedded platforms.

FAQ
What is the default I/O configuration of the SST26VF064BT-104I/TD at power-up?
The SST26VF064BT-104I/TD powers up in SPI mode with IOC = 0, enabling WP# and HOLD# pins while disabling SIO2 and SIO3. This matches the SST26VF064B variant. To activate Quad I/O, the host must issue EQIO and set IOC = 1 in the Configuration register. The SST26VF064BT-104I/TD retains this behavior regardless of package type or temperature grade.
Does the SST26VF064BT-104I/TD support true Quad I/O mode, and how is it enabled?
Yes, the SST26VF064BT-104I/TD supports true Quad I/O mode using SIO[3:0] for bidirectional command/address/data transfer. It is enabled by issuing the EQIO command (38H) and setting the IOC bit (bit 1) in the Configuration register. Once configured, instructions like SQOR (6BH) and SQIOR (EBH) become valid. The SST26VF064BT-104I/TD does not auto-detect Quad mode-it requires explicit host configuration.
How does hardware write protection work on the SST26VF064BT-104I/TD?
Hardware write protection on the SST26VF064BT-104I/TD uses the WP# pin only when IOC = 0 and WPEN = 1. In that state, pulling WP# low disables writes to the Block Protection and Configuration registers. The SST26VF064BT-104I/TD ignores WP# in Quad I/O mode or if IOC = 1. WPEN is nonvolatile, so its setting persists across power cycles unless explicitly cleared.
What is the purpose and behavior of the Security ID feature in the SST26VF064BT-104I/TD?
The SST26VF064BT-104I/TD includes a 2-Kbyte Security ID (Sec ID) area: 64 bits factory-programmed with a unique identifier (read-only), and the remainder user-programmable. The LSID command permanently locks the entire Sec ID space, preventing further writes. Once locked, the SEC bit in the STATUS register remains '1' indefinitely-even after power cycles-ensuring immutable device identity for authentication in the SST26VF064BT-104I/TD.
Can the SST26VF064BT-104I/TD perform simultaneous read and write operations?
No, the SST26VF064BT-104I/TD does not support true simultaneous read/write. However, it supports write suspend: an active erase or program operation can be paused using the SUSPEND command, allowing reads from other unprotected sectors. After servicing the read, the suspended operation resumes automatically. This capability is confirmed in the SST26VF064BT-104I/TD datasheet Section 4.0 and enables responsive behavior in real-time systems.
