Product details
Overview
SST26VF064BT-104V/MN 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 and SQI protocols, features uniform 4-Kbyte sectors and 64-Kbyte blocks, and delivers 100,000 program/erase cycles with >100-year data retention - deployed in industrial controllers and automotive infotainment boot memory.
For engineers reviewing the SST26VF064BT-104V/MN datasheet, SST26VF064BT-104V/MN pinout, SST26VF064BT-104V/MN application, or SST26VF064BT-104V/MN equivalent, key selection criteria include quad-I/O burst performance, hardware write protection via WP#/HOLD#, flexible block-level security ID and lock-down registers, and AEC-Q100 Grade 2 qualification for automotive use.
Technical Context
This device implements Microchip's proprietary SuperFlash® technology with split-gate cells and thick-oxide tunneling, enabling faster erase (18 ms sector typical) and lower energy per operation versus conventional NOR Flash. It supports dual-mode operation: default SPI mode (SI/SO pins active, WP#/HOLD# enabled) and configurable SQI mode (SIO[3:0] multiplexed I/O, IOC bit = 1).
The internal architecture includes a 64-Mbit array organized into eight 8-Kbyte parameter blocks, two 32-Kbyte overlay blocks, one hundred twenty-six 64-Kbyte overlay blocks, and uniform 4-Kbyte sectors. Command execution uses Mode 0 or Mode 3 clock polarity, with status polling via BUSY bit and end-of-write detection through STATUS register reads.
Key Specifications

Pinout & Package
Package: 8-contact WDFN (6 mm × 5 mm), RoHS-compliant, moisture-sensitive level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CE# | Chip Enable | Active-low chip select; must remain low during command/data sequences to prevent premature termination |

| WP#/SIO2 | Write Protect Input / Quad I/O 2 | Hardware write-protection control in SPI mode; becomes SIO2 in SQI mode (IOC = 1) |
| VSS | Ground | Reference return path for all I/O and core logic; requires low-impedance PCB connection |
| VDD | Power Supply | 2.3–3.6 V supply input; decoupling capacitor (0.1 µF) required adjacent to pin |
| HOLD#/SIO3 | Hold Input / Quad I/O 3 | Pauses ongoing SPI transfers without resetting state; disabled in SQI mode and when IOC = 1 |
| SCK | Serial Clock | Timing reference for all serial operations; rising edge latches inputs, falling edge shifts out outputs |

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), no built-in Security ID | Lacks quad I/O acceleration and factory-unique UID; requires external security layer for key binding | Choose when cost sensitivity outweighs need for SQI speed or hardware-based identity |
| Cypress S25FL164K0XMFI010 | 64 Mbit, 80 MHz max, supports HyperBus but not SQI; includes 128-byte OTP security register | Lower clock rate limits burst throughput; HyperBus interface requires different controller IP | Prefer when existing design uses Cypress-compatible HyperFlash controllers and prioritizes pin compatibility over speed |
Compared with W25Q64JVSSIQ and S25FL164K0XMFI010, SST26VF064BT-104V/MN uniquely combines 104 MHz SQI bandwidth, AEC-Q100 Grade 2 qualification, and factory-programmed 64-bit Security ID - making it optimal for automotive and secure industrial firmware storage where speed, reliability, and identity assurance are jointly critical.

FAQ
What is the maximum operating frequency of the SST26VF064BT-104V/MN?
The SST26VF064BT-104V/MN supports a maximum clock frequency of 104 MHz when operated within the 2.7–3.6 V supply range. At 2.3–3.6 V, the maximum frequency is reduced to 80 MHz. This specification applies to both SPI and SQI modes, with actual achievable throughput depending on I/O width (x1/x2/x4) and command overhead.
Does the SST26VF064BT-104V/MN support Quad I/O mode by default?
No - the SST26VF064BT-104V/MN powers up in SPI mode with SI/SO pins active and WP#/HOLD# enabled. To activate Quad I/O mode, the I/O Configuration (IOC) bit in the Configuration register must be set to '1', which disables WP#/HOLD# and enables SIO[3:0] as bidirectional lines. The SST26VF064BA variant ships with IOC = 1 by default, but SST26VF064BT-104V/MN follows the 'B' configuration.
How is hardware write protection implemented on the SST26VF064BT-104V/MN?
Hardware write protection on the SST26VF064BT-104V/MN is controlled by the WP# pin in conjunction with the WPEN bit in the Configuration register. When WPEN = 1 and WP# is driven low, writes to the Block Protection and Configuration registers are prohibited. The WP# pin is only functional in SPI single/dual-bit read mode and is disabled in SQI mode or when IOC = 1.
What security features does the SST26VF064BT-104V/MN provide beyond basic write protection?
The SST26VF064BT-104V/MN includes a 2-Kbyte Security ID space with a factory-programmed 64-bit unique identifier and user-programmable area, plus nonvolatile Write Lock Lock-Down (nVWLDR) bits that permanently fix block protection states. These features enable secure boot authentication, device identity binding, and irreversible firmware partition locking - exceeding standard SPI Flash security capabilities.
Is the SST26VF064BT-104V/MN qualified for automotive applications?
Yes - the SST26VF064BT-104V/MN 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, body control modules, and ADAS subsystems. Its SuperFlash® technology, 100-year data retention, and robust ESD tolerance further support automotive deployment requirements.
