Product details
Overview
SST26VF064B-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. It is widely deployed in industrial controllers and automotive infotainment boot memory.
For engineers reviewing the SST26VF064B-104V/MN datasheet, SST26VF064B-104V/MN pinout, SST26VF064B-104V/MN application, or SST26VF064B-104V/MN equivalent, key selection considerations include its dual-mode SPI/SQI interface, hardware write protection via WP#/HOLD# pins, flexible block-level security ID and protection register, and support for burst read with wrap-around across multiple package options including 8-lead SOIJ and 8-contact WDFN.
Technical Context
The SST26VF064B-104V/MN implements a six-wire, 4-bit multiplexed I/O interface compliant with both legacy SPI (Mode 0/3) and high-throughput SQI protocols. Its SuperFlash® split-gate cell architecture enables single-supply operation (2.3–3.6 V), fast erase (18 ms sector, 35 ms chip), and low active current (15 mA @ 104 MHz).
It integrates configurable I/O mode control via the IOC bit in the Configuration register: default power-up state disables SIO2/SIO3 and enables WP#/HOLD# (SPI mode), while enabling SQI requires explicit IOC=1. The device includes dedicated status and configuration registers for real-time BUSY polling, write suspend, and nonvolatile lock-down of protection bits.

Pinout & Package
Package: 8-lead SOIJ (5.28 mm), lead-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CE# | Chip Enable | Active-low enable for command execution; must remain low during full instruction sequence |
| SO/SIO1 | Serial Output / Quad I/O 1 | Default SPI output pin; multiplexed as bidirectional I/O in SQI mode after IOC=1 |
| WP#/SIO2 | Write Protect Input / Quad I/O 2 | Hardware write-protection for Block Protection register in SPI mode; repurposed as SIO2 in SQI mode |
| VSS | Ground | Reference return path for all digital and analog circuitry; decoupling required near pin |
| VDD | Power Supply | 2.3–3.6 V supply input; requires local 100 nF ceramic decoupling capacitor |
| HOLD#/SIO3 | Hold Input / Quad I/O 3 | Pauses ongoing SPI transfers without resetting clock phase; disabled in SQI mode |
| SCK | Serial Clock | Master-generated timing signal; rising edge latches input, falling edge shifts out data |
| SI/SIO0 | Serial Input / Quad I/O 0 | Default SPI input pin; multiplexed as bidirectional I/O in SQI mode after IOC=1 |
Key Features
| Feature | Design Value |
|---|---|
| Quad I/O Interface | Enables 4-bit parallel data transfer on SIO[3:0], quadrupling bandwidth vs. standard SPI at same clock frequency |
| Flexible Erase Architecture | Uniform 4-Kbyte sectors plus configurable 8/32/64-Kbyte overlay blocks - supports partial firmware updates without full chip erase |
| Write Suspend Capability | Allows interruption of active Program or Erase to service higher-priority reads - critical for real-time system responsiveness |
| Nonvolatile Block Protection Lock-Down | One-Time-Programmable (OTP) bits permanently fix write-lock states per block - prevents accidental or malicious reconfiguration |
| Security ID with Lockout | Factory-programmed 64-bit unique ID + 2-Kbyte user area; LSID command permanently disables further writes to entire Sec ID space |

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 integrated Security ID | Lacks quad I/O bandwidth and hardware-based secure identity - less suitable for secure boot or high-throughput code fetch | Select when cost sensitivity outweighs need for SQI speed or OTP ID; verify layout compatibility with 8-lead SOIC footprint |
| Cypress S25FL164K0XMFI00 | 64 Mbit, 80 MHz max, supports XIP but no SQI; includes 128-byte OTP array (not 2-Kbyte) | Lower clock rate limits code execution speed; smaller OTP area restricts secure credential storage depth | Prefer for legacy designs already using Spansion-compatible command set; not recommended for new SQI-optimized platforms |
Compared with SST26VF064B-104V/MN, W25Q64JVSSIQ offers higher clock speed but lacks SQI interface and Security ID, limiting secure high-bandwidth use cases; S25FL164K0XMFI00 provides XIP support but trades off clock rate and OTP capacity, making it less optimal for automotive boot or industrial firmware integrity requirements.

FAQ
What interface modes does the SST26VF064B-104V/MN support?
The SST26VF064B-104V/MN supports both traditional SPI (x1/x2 modes, Mode 0/3) and high-speed Serial Quad I/O™ (SQI) protocol with x4 data transfer. At power-up, SST26VF064B-104V/MN defaults to SPI mode with WP#/HOLD# enabled; SQI mode is activated by setting the IOC bit in the Configuration register and issuing EQIO command. This dual-mode flexibility allows backward compatibility and performance scaling within the same footprint.
Does the SST26VF064B-104V/MN support hardware write protection?
Yes, the SST26VF064B-104V/MN supports hardware write protection via the WP# pin, but only in SPI single-bit/dual-bit read mode when the IOC bit is '0' and WPEN bit is '1'. In that configuration, pulling WP# low disables writes to the Block Protection and Configuration registers. The SST26VF064B-104V/MN also supports nonvolatile lock-down of protection bits, which supersedes WP# functionality once enabled.
What is the purpose of the Security ID feature in the SST26VF064B-104V/MN?
The SST26VF064B-104V/MN includes a 2-Kbyte Security ID (Sec ID) space comprising a factory-programmed 64-bit unique identifier and a user-programmable segment. This enables device authentication and secure boot workflows. Once programmed, the entire Sec ID space can be permanently locked using the LSID command - a feature critical for preventing cloning or unauthorized firmware replacement in certified systems.
How does the SST26VF064B-104V/MN handle power supply variations?
The SST26VF064B-104V/MN operates across a wide voltage range of 2.3 V to 3.6 V, supporting both 2.5 V and 3.0 V system rails. Its SuperFlash® technology minimizes current draw during program/erase operations, resulting in typical active read current of 15 mA at 104 MHz and standby current of just 15 µA. This ensures robust operation in battery-powered or dynamically regulated power domains without compromising speed or reliability.
Is the SST26VF064B-104V/MN qualified for automotive applications?
Yes, the SST26VF064B-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 industrial-plus temperature rating, built-in ECC (implied by SuperFlash reliability), and hardware security features align with functional safety requirements for ASIL-B–capable systems where firmware integrity is critical.
