Product details
Overview
SST26VF064BT-104V/SO from Microchip Technology is a 64-Mbit Serial Quad I/O™ (SQI™) Flash memory IC operating at up to 104 MHz in 2.7V–3.6V supply, featuring uniform 4-Kbyte sectors, 100,000-program/erase endurance, and industrial temperature range (–40°C to +85°C). It supports SPI x1/x2/x4 and SQI protocols in an 8-lead SOIJ package for embedded boot code and firmware storage.
For engineers reviewing the SST26VF064BT-104V/SO datasheet, SST26VF064BT-104V/SO pinout, SST26VF064BT-104V/SO application, or SST26VF064BT-104V/SO equivalent, key selection criteria include quad-I/O throughput, flexible block protection granularity, hardware write-protection pin behavior, and verified 104 MHz read timing under 2.7–3.6 V operation.
Technical Context
This device implements Microchip's proprietary SuperFlash® technology with split-gate cells and thick-oxide tunneling injectors, enabling faster erase (18 ms typical sector erase) and lower total energy per program/erase cycle versus conventional NOR Flash. Its dual-mode interface supports backward-compatible SPI (Mode 0/3) and high-speed SQI with four multiplexed I/Os (SIO[3:0]).
The SST26VF064BT-104V/SO uses a configurable I/O Configuration (IOC) bit to toggle between SPI mode (WP#/HOLD# active, SI/SO functional) and Quad I/O mode (SIO2/SIO3 enabled), with factory default IOC = 0 for this variant. Memory organization includes eight 8-Kbyte parameter blocks, two 32-Kbyte overlay blocks, and 126 uniform 64-Kbyte overlay blocks.

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 SPI-only (no SQI), max 133 MHz read, no hardware WP#/HOLD# pins in 8-SOIC; uses standard SPI command set. | Lacks quad I/O acceleration and dedicated hardware write-protect; suitable where board layout already uses SI/SO routing and speed >104 MHz is not required. | Select when cost sensitivity outweighs need for SQI bandwidth or hardware protection pins; verify compatibility with existing SPI controller driver stack. |
| Cypress S25FL164K0XMFI010 | 64 Mbit HyperFlash-compatible, 133 MHz DDR read, different command set (8- or 16-bit wide), no OTP Security ID or parameter block read-lock. | Optimized for high-speed execute-in-place (XIP) from flash; lacks fine-grained 8-Kbyte parameter protection and factory-unique ID for secure boot. | Prefer for applications requiring XIP execution and DDR interface; avoid if secure device identity or per-parameter-block read locking is mandatory. |
Compared with W25Q64JVSSIQ and S25FL164K0XMFI010, the SST26VF064BT-104V/SO uniquely combines 104 MHz SQI throughput, hardware WP#/HOLD# pins in 8-lead SOIJ, OTP Security ID with factory-unique 64-bit ID, and granular 8-Kbyte parameter block protection-making it optimal for secure, space-constrained industrial and automotive firmware storage.

FAQ
What is the maximum operating frequency of the SST26VF064BT-104V/SO, and under what voltage conditions?
The SST26VF064BT-104V/SO supports a maximum clock frequency of 104 MHz when operated within the 2.7 V to 3.6 V supply range. At lower voltages (2.3 V–3.6 V), the maximum frequency drops to 80 MHz. This specification is measured and guaranteed per Microchip's DS20005119K datasheet, and applies to both SPI and SQI read operations. The "104" in the part number explicitly denotes this 104 MHz rating under nominal 3.3 V conditions.
Does the SST26VF064BT-104V/SO support Quad I/O mode, and how is it enabled?
Yes, the SST26VF064BT-104V/SO supports Quad I/O (SQI) mode using its SIO[3:0] pins. To enable it, the I/O Configuration (IOC) bit (bit 1 of the Configuration register) must be set to '1' via the WRSR instruction. After IOC=1, commands like SQOR (6BH) and SQIOR (EBH) become valid. Note that the SST26VF064BT-104V/SO ships with IOC=0 by default, so explicit configuration is required before using quad-mode instructions.
What package type does the SST26VF064BT-104V/SO use, and what are its key mechanical dimensions?
The SST26VF064BT-104V/SO uses an 8-lead Small Outline J-bend (SOIJ) package with a 5.28 mm body width, per JEDEC MS-012AC. Lead pitch is 1.27 mm, and overall package height is ≤2.65 mm. This compact, gull-wing leaded package supports standard reflow soldering and is optimized for high-density PCB layouts where footprint area is constrained.
How does hardware write protection work on the SST26VF064BT-104V/SO, and what pins are involved?
Hardware write protection on the SST26VF064BT-104V/SO is controlled by the WP# pin in conjunction with the nonvolatile WPEN bit in the Configuration register. When WPEN=1 and WP# is driven low, writes to the Block Protection and Configuration registers are blocked. WP# only functions in SPI single/dual-bit modes-not in SQI mode-and is disabled when IOC=1. The SST26VF064BT-104V/SO defaults to WPEN=0 at power-up, disabling WP# until explicitly enabled.
What is the purpose and structure of the Security ID feature in the SST26VF064BT-104V/SO?
The SST26VF064BT-104V/SO includes a 2-Kbyte Security ID (Sec ID) space comprising a factory-programmed 64-bit unique identifier (immutable) and a user-programmable segment. It supports PSID (Program Security ID) and LSID (Lockout Security ID) commands. Once locked via LSID, the entire Sec ID space becomes read-only. This feature enables secure device authentication, firmware binding, and anti-cloning in regulated applications such as medical and industrial control systems.
