Product details
Overview
SST26WF064C-104I/MF from Microchip Technology is a 1.8V, 64 Mbit Serial Quad I/O (SQI) flash memory IC designed for high-speed, low-power code storage and execution in embedded systems. It delivers 104 MHz single-data-rate (SDR) clock performance, supports x1/x2/x4 SPI and SQI protocols, and features uniform 4 KByte sectors with flexible block protection - deployed in industrial-grade applications including IoT edge nodes and automotive infotainment boot memory.
For engineers reviewing the SST26WF064C-104I/MF datasheet, SST26WF064C-104I/MF pinout, SST26WF064C-104I/MF application, or SST26WF064C-104I/MF equivalent, key selection criteria include its 1.65–1.95 V single-supply operation, 100,000-cycle endurance, JEDEC SFDP compliance, hardware reset capability, and WDFN-8 (6 mm × 5 mm) package compatibility with space-constrained PCB layouts.
Technical Context
The SST26WF064C-104I/MF implements a six-wire, 4-bit multiplexed I/O interface supporting both Mode 0 and Mode 3 SPI timing, with configurable SIO[3:0] pins that operate in SPI (SI/SO) or SQI (quad I/O) mode based on the IOC bit in the Configuration Register. Its SuperFlash® technology enables fast erase (18 ms sector/25 ms max) and page-program (256-byte pages) with single 1.65–1.95 V supply.
It integrates dual protection mechanisms: volatile Write-Protection Lock-Down (WPLD) and non-volatile Write-Lock Lock-Down (nVWLDR), plus a factory-programmed 64-bit Security ID and user-programmable 2 KByte OTP area. The device defaults to SPI mode at power-up and supports software polling of the BUSY bit for end-of-write detection.
Key Specifications

|---|---|
| Memory Density | 64 Mbit (8 MByte) organized as 126 × 64 KByte blocks + parameter overlay blocks |
| Operating Voltage | 1.65–1.95 V - enables direct interfacing with 1.8 V logic without level-shifting |
| Max Clock Frequency | 104 MHz SDR / 50 MHz DTR - delivers up to 416 MB/s effective throughput in x4 SQI mode |
| Endurance & Retention | 100,000 program/erase cycles minimum; >100 years data retention - suitable for firmware update storage |
| Power Consumption | 15 mA active read current @ 104 MHz; 10 µA standby; 2.5 µA deep power-down - critical for battery-powered devices |
| Erase Time | 18 ms typical sector erase (4 KByte); 35 ms typical chip erase - reduces firmware update latency |
| Security Features | One-time programmable 2 KByte Security ID with factory 64-bit unique ID and lockout capability - supports secure boot authentication |
Pinout & Package
Package: 8-contact WDFN (6 mm × 5 mm), RoHS-compliant, industrial temperature range (−40°C to +85°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CE# | Chip Enable | Active-low enable signal; must remain low during full command/data sequence - controls device selection in multi-flash systems |
| SIO0 (SI) | Serial Data Input (SPI default) | Latches commands/addresses/data on rising SCK edge - primary input path in SPI mode |
| SIO1 (SO) | Serial Data Output (SPI default) | Drives output data on falling SCK edge - used for read operations in SPI mode |
| WP# | Write Protect Input | Hardware-enables write-protection of Block-Protection and Configuration registers when WPEN=1 and IOC=0 - prevents accidental firmware corruption |
| VSS | Ground | Reference return path for all I/O and core logic - requires low-impedance PCB grounding |
| VDD | Power Supply | 1.65–1.95 V supply input - powers internal charge pumps and I/O buffers |
| RESET#/HOLD# | Multi-function pin | Configurable as hardware reset (active-low) or hold signal; defaults to HOLD# at power-up (IOC=0) - pauses ongoing transfers without resetting state |
| SCK | Serial Clock | Timing reference for all serial transactions; sampled on rising edge for inputs, drives outputs on falling edge - determines maximum interface speed |
Key Features
| Feature | Design Value |
|---|---|
| Quad I/O (SQI) Interface | Enables 4-bit bidirectional data transfer on SIO[3:0], quadrupling bandwidth vs. standard SPI at same clock frequency - reduces interface bottlenecks in high-speed boot scenarios |
| Flexible Erase Architecture | Uniform 4 KByte sectors + eight 8 KByte parameter blocks + two 32 KByte overlays + one hundred twenty-six 64 KByte blocks - supports granular firmware partitioning and OTA update staging |
| Write-Suspend Capability | Allows suspension of active Program or Erase operations to service higher-priority reads - essential for real-time systems requiring deterministic response |
| Dual Protection Scheme | Volatile WPLD (cleared on reset) and non-volatile nVWLDR (OTP) provide layered security against unauthorized writes - meets functional safety requirements for locked bootloader regions |
| JEDEC SFDP Compliance | Provides standardized, discoverable parameter table for automatic host configuration - eliminates hardcoded timing values and improves design portability across flash vendors |

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, 3.3 V supply, 133 MHz max clock, no SQI support - uses standard quad SPI only | Lacks SQI interface and 1.8 V operation; requires level-shifting in 1.8 V systems | Select when legacy SPI compatibility and higher voltage margin outweigh bandwidth and power advantages |
| Cypress S25FL164K0XMFI010 | 64 Mbit, 1.8 V, 85 MHz max clock, supports XIP but no DTR mode - no Dual-Transfer Rate capability | Lower max clock and no DTR limits sustained throughput in high-bandwidth streaming use cases | Prefer when eXecute-In-Place (XIP) functionality is required and 104 MHz SDR is sufficient |
Compared with SST26WF064C-104I/MF, W25Q64JVSSIQ trades 1.8 V operation and SQI bandwidth for broader ecosystem support, while S25FL164K0XMFI010 offers XIP but sacrifices 19 MHz clock headroom and DTR efficiency - making SST26WF064C-104I/MF optimal for 1.8 V, high-throughput, low-power embedded boot applications.

FAQ
What is the operating voltage range of the SST26WF064C-104I/MF?
The SST26WF064C-104I/MF operates from 1.65 V to 1.95 V, optimized for 1.8 V systems. This single-supply range eliminates the need for external level shifters when interfacing with 1.8 V microcontrollers or SoCs. The device maintains full functionality-including 104 MHz SDR operation and all protection features-across this voltage window, as verified in DS20005430C.
Does the SST26WF064C-104I/MF support both SPI and SQI protocols?
Yes, the SST26WF064C-104I/MF supports full command-set compatibility with traditional SPI (x1/x2/x4 modes) and native Serial Quad I/O (SQI) protocol. At power-up, it defaults to SPI mode; SQI mode is enabled via the I/O Configuration (IOC) bit in the Configuration Register. Both Mode 0 and Mode 3 clock polarity/timing are supported per JEDEC JESD251.
How does the SST26WF064C-104I/MF implement hardware write protection?
The SST26WF064C-104I/MF uses the WP# pin in conjunction with the WPEN bit (non-volatile) and IOC bit (volatile) in the Configuration Register. When IOC = 0 and WPEN = 1, asserting WP# low disables writes to the Block-Protection and Configuration registers. Factory default sets WPEN = 0, disabling WP# at startup unless explicitly programmed - preventing unintended lockout during initial deployment.
What package options are available for the SST26WF064C-104I/MF?
The SST26WF064C-104I/MF is offered in four packages: 8-contact WDFN (6 mm × 5 mm), 8-lead SOIJ (5.28 mm), 16-lead SOIC (7.50 mm), and 24-ball TBGA (8 mm × 6 mm). The -104I/MF suffix specifically denotes the 8-contact WDFN variant with industrial temperature grade (−40°C to +85°C) and RoHS compliance - confirmed in Microchip's DS20005430C datasheet revision C.
Can the SST26WF064C-104I/MF be used for secure boot applications?
Yes, the SST26WF064C-104I/MF supports secure boot via its 2 KByte Security ID (Sec ID) feature: a factory-programmed 64-bit unique identifier and a user-programmable OTP area. The LSID (Lockout Security ID) command permanently disables further writes to this region, ensuring cryptographic keys or device identity remain tamper-proof - a capability validated in Section 4.3 of DS20005430C.
