SST26VF064BT-104I/SM 개요
SQI flash memory (also called Serial Quad I/O or Quad SPI flash) is a class of NOR flash that uses a 4-bit multiplexed I/O interface to achieve SPI throughput roughly four times higher than legacy SPI while keeping the same low pin count. Within the memory taxonomy it sits under NOR flash -> non-volatile memory -> semiconductor memory. Compared with traditional SPI flash, SQI devices occupy less board space and lower BOM cost while supporting execute-in-place (XIP) operation directly from flash in systems without external RAM.
Key features include a 104 MHz maximum clock rate, hardware and software write protection, a 100K endurance rating per sector, and a 256-byte security register with one-time-programmable (OTP) lock. The device also supports JEDEC JESD216-compliant SFDP discovery for in-system configuration, plus a deep power-down mode drawing as little as 1.5 µA, well-suited to battery-powered designs that need to wake quickly.
The SST26VF064BT-104I/SM uses a single 2.5V/3.3V power supply with separate VDD and VSS pins for clean return-path layout. Internal block-locking and a hardware WP# pin enable field firmware updates with rollback protection. The 8-SOIJ package is pin-compatible with industry-standard 8-SOIC footprints, simplifying PCB migration from lower-density SQI devices.
Typical applications include IoT edge nodes, automotive infotainment boot storage, industrial HMI graphics framebuffers, networking firmware and bootloader storage, medical instrument data logging, and consumer wearables running XIP code directly from flash.
Designers should place a 0.1 µF decoupling capacitor within 3 mm of the VDD pin and route the SCK trace with 50 Ω characteristic impedance and length matching within 5 mm of the data lines to preserve signal integrity at 104 MHz operation.

IoT Edge Node Firmware Boot Storage
Provides reliable primary firmware storage in connected-sensor endpoints that wake intermittently to push telemetry to a gateway or cloud. The SST26VF064BT-104I/SM's 80 MB/s Quad-I/O read bandwidth lets a Cortex-M4 host execute code directly (XIP), eliminating external PSRAM cost, while 1.5 µA deep-power-down current matches the sub-uA sleep targets of LoRa or BLE designs that operate from coin-cell or harvested energy rails.

Automotive Infotainment Boot Flash
Stores ECU firmware, icon assets, and bootloader images on automotive infotainment or cluster controllers. The SST26VF064BT-104I/SM's 8-SOIJ (208-mil) package and 2.7-3.6 V supply align with 3.3 V NOR flash rails common in head-unit designs. The AEC-Q100 sibling SST26VF064BAT-104I/SM provides the same footprint for modules that need to clear -40 C to +125 C stress profiles on cabin and engine-bay harnesses.

Industrial HMI Touch Display Framebuffer
Hold graphics assets, touch-calibration tables, and runtime logs for industrial touch screens driving 480x272 to 1280x720 TFT panels. The SST26VF064BT-104I/SM gives 64 Mbit of fast-read storage so the HMI controller can refresh partial icon caches without penalty, and the 8-SOIJ package tolerates -40 C to +85 C cabinet ambient expected in factory-floor and outdoor equipment that contains an embedded display.
추천
Networking Switch Firmware and Configuration
Stores switch firmware, port-mac-address tables, and runtime telemetry on managed 1G/10G switches and Wi-Fi routers. The SST26VF064BT-104I/SM's serial Quad-I/O interface feeds SPI peripherals integrated on switch controllers like the PIC32MZ port family, freeing pin budget for PoE, fan, and PHY-management signals on the same board while sustaining 104 MHz read throughput during fast boot-and-upgrade cycles.

Medical Instrument Data Logging
Provides non-volatile storage for blood-glucose, spirometer, and other portable medical devices where every KB of audit trail matters. The SST26VF064BT-104I/SM's 100,000-cycle sector endurance supports >250 measurements/day for over a year per sector, and its hardware WP# pin enables safe firmware updates that prevent accidental corruption of regulated clinical data during patient-use field updates.
추천
Consumer Wearable Firmware Storage
Holds firmware and configuration on smartwatches, fitness bands, and BLE earbuds where the host MCU sleeps aggressively between events. The SST26VF064BT-104I/SM's 1.5 µA deep power-down current plus fast 100 µs wake-up enables <2 ms boot from flash on touch wake, and the 8-SOIJ (208-mil) package sits beside 50 mAh Li-Po cells without crowding the wristband enclosure.

설계 노트
Place the 0.1 µF VDD decoupling capacitor within 3 mm of pin 8 (VDD) and return it directly to pin 4 (GND) with a via-stitching pattern, since SST26VF064B draws 15 mA peaks during 104 MHz read that couple into VDD/GND rails. Route SCK on a 50-Ω-controlled trace; match length-to-SI and length-to-SO within 5 mm to avoid timing skew on Quad-I/O data setup at 104 MHz. Use a guard ground ring around the SOIJ body to reduce coupling from adjacent switching signals.
At 104 MHz, expect approximately 17 ns rise times on SCK, which require a 4-layer PCB stack-up to maintain return paths. Source-series-terminate SCK with 33 Ω if the host clock driver is a strong CMOS buffer; the SQI bus also needs weak pull-ups on CS#, WP# and HOLD# so floating inputs do not enter spurious Quad-I/O mode during host boot. Tape-and-reel parts use the same die; no signal-integrity downgrade versus the tube-packaged variant.
The deep power-down mode drops current to 1.5 µA, but resume time is typically 100 µs; budget this in duty-cycle calculations for IoT designs. The active read current at 104 MHz Quad-I/O reaches 15 mA, so a 3.3 V LDO with at least 30 mA headroom is required to avoid rail collapse during burst reads. VDD rise time must follow the 30 µs minimum VDD ramp guidance to prevent erase/status-register lockup at boot, particularly on brown-out recovery.
Do not confuse SST26VF064B (top-boot) with SST26VF064B without the 'T' letter - the top-boot variant places small 4 KB sectors at the highest address, which is critical when tiny updates land in the configuration region. Always tie WP# to VDD via a 10 kΩ resistor when not used; leaving WP# floating may inadvertently enable write-protection or push DQ2 into Quad-I/O mode. Manufacturers also warn against stacked SQI CS# lines - each device on the bus needs a dedicated CS# or shared bus contention occurs.
