SST25VF010A-33-4I-SAE 概要
A serial flash memory is a non-volatile storage device that uses a synchronous serial interface (SPI) instead of a parallel bus, allowing a much smaller pin count and PCB footprint. Serial flash devices sit within the NOR Flash family of memory ICs and are widely used for code storage, boot images, configuration tables, and firmware updates in embedded systems where board space is at a premium. The SPI interface defined by Motorola (now NXP) became the de facto standard because it needs only four signal lines (SCK, CS#, SO/SI, SI/SO) and is supported by virtually every microcontroller and SoC.
Key features of the SST25VF010A-33-4I-SAE include 4-wire SPI compatibility, low-power consumption with typical 10 mA active read current and 15 uA standby current, 100,000 endurance program/erase cycles per sector, and greater than 100-year data retention. The device is built on the proprietary CMOS SuperFlash split-gate cell with thick-oxide tunneling injector, providing reliable read/program/erase operations and excellent manufacturability. It supports sector erase (4 KB sector size) and full chip erase commands, byte-level programming via Page Program, and JEDEC-standard 3-byte addressing.
Architecturally, the SST25VF010A integrates a 1-Mbit SuperFlash memory array with an SPI controller, a precision bandgap reference for erase/program voltage generation, an on-chip oscillator, and a status register for write-protection and busy/RDY feedback. The four-wire SPI bus with MODE 0 and MODE 3 support simplifies interface to most MCUs, while hardware write protection via the WP# pin and software protection through the Status Register provide configurable array protection.
Typical applications include firmware storage in IoT endpoints, BIOS/UEFI boot ROM in set-top boxes and routers, data logging in industrial sensor nodes, configuration parameter storage in consumer appliances, and small-asset audio/voice prompt storage in toys and white goods. The wide operating voltage range also suits battery-powered designs where 3 V lithium cells are used.
When designing with this device, note that SST25VF010A-33-4I-SAE is the -I (industrial) temperature grade - for commercial-grade applications consider the -4C variant. The 33 MHz SPI clock is the original datasheet rating; the -A revision device family is also rated for 60 MHz in newer product briefs. Designers should add a 0.1 uF decoupling capacitor close to VDD and follow JEDEC JESD22-A114 ESD handling guidelines for production.

主な用途
SST25VF010A-33-4I-SAE の用途: 6 件s: IoT Sensor Node Firmware Storage, Set-Top Box BIOS/UEFI Boot ROM, Industrial Sensor Data Logger, Consumer Appliance Configuration Storage, Audio/Voice Prompt Storage in Toys, Automotive Aftermarket Accessory Firmware.
IoT Sensor Node Firmware Storage
The SST25VF010A-33-4I-SAE is widely used as the boot and application firmware repository in low-power IoT sensor nodes that need reliable code shadowing in less than 128 KB. The 2.7 V to 3.6 V supply matches the voltage of common Li-SOCl2 primary cells and 2xAA battery packs, while the 15 uA typical standby current preserves battery life when the host MCU is asleep. With a 33 MHz SPI clock the device easily keeps pace with ARM Cortex-M0/M4 boot sequences; the 4-wire SPI footprint and 8-SOIC package free up GPIO on the host MCU. Designers should pair it with a small MCU such as the PIC18 or SAM D series and add a 0.1 uF decoupling cap close to VDD.
おすすめ
Set-Top Box BIOS/UEFI Boot ROM
The SST25VF010A-33-4I-SAE serves as a cost-effective boot ROM in set-top boxes, IPTV gateways, and entry-level home routers where a small read-mostly code image lives outside the main SoC. Its 4-wire SPI interface is standard on virtually every broadband SoC, and 1 Mbit provides ample space for a second-stage bootloader plus default configuration. The 33 MHz SPI clock rate supports fast cold-boot requirements, while the 100,000-cycle endurance and >100-year retention keep maintenance windows very long. Pair it with a 3.3V LDO supplying both the SoC and flash; ensure CS# is pulled up to VDD through 10 kohm to prevent floating during reset.
おすすめ
Industrial Sensor Data Logger
In factory automation and process control the SST25VF010A-33-4I-SAE provides non-volatile circular-log storage of process telemetry, calibration constants, and error logs. The industrial -40C to +85C temperature rating suits cabinet-mounted and outdoor-edge environments, while the 4 KB sector erase granularity matches typical log-block sizes for wear leveling. Combined with an RS485 transceiver and a small MCU the device can buffer days of measurement data during network outages; the 33 MHz SPI allows rapid post-outage dump to a service laptop. Add a TVS diode on the SPI lines when the harness runs outside the cabinet.
おすすめ
Consumer Appliance Configuration Storage
White-goods and small kitchen appliances use the SST25VF010A-33-4I-SAE to store user preferences, wash-cycle profiles, and fault-history flags that must survive power cycles. The 8-SOIC footprint is small enough to fit on a tightly-packed keypad PCB, and the 15 uA standby draw has negligible impact on the always-on standby supply budget. A 33 MHz SPI keeps the boot time of the user interface MCU short, which improves perceived product responsiveness. Designers should follow JEDEC JESD22-A114 ESD handling rules during the appliance line assembly.
おすすめ
Audio/Voice Prompt Storage in Toys
Children's learning toys and talking novelty products use the SST25VF010A-33-4I-SAE as cost-effective storage for short PCM voice prompts, song clips, and sound effects. At 1 Mbit (128 KB) the part holds roughly 12 seconds of 8 kHz / 8-bit audio or more when using ADPCM compression, enough for several prompts. The 4-wire SPI bus is easily served by low-cost MCUs such as the PIC16 or ATtiny series, and the small 8-SOIC package preserves board area for speakers and battery compartments. Use byte-program rather than page-program for short clips to simplify firmware wear leveling.
おすすめ
Automotive Aftermarket Accessory Firmware
The SST25VF010A-33-4I-SAE is sometimes used in aftermarket automotive accessories such as trip computers, gauge clusters, and OBD-II dongles to store firmware and trip-log data. The industrial -40C to +85C rating covers cabin and under-hood-edge environments in most climates. Designers should add an external TVS array on the SPI lines and supply rail, because the 12V automotive bus can carry load-dump transients far above the 3.6 V absolute maximum. For OE programs choose an AEC-Q100 qualified variant; this commercial-industrial part is best for accessories rather than safety-critical modules.

設計ノート
Place a 0.1 uF decoupling capacitor as close as possible to the VDD pin (pin 8) and a 10 uF bulk capacitor on the same 3.3 V rail. The SST25VF010A can draw up to 10 mA active read current with brief programming peaks; insufficient bulk capacitance on a high-impedance rail can cause VDD droop and read errors. Tie CS#, WP#, and HOLD# to VDD through 10 kohm pull-ups so the device does not enter an unintended state during MCU reset.
Route SCK, SI, SO, and CS# traces as a matched-length bus with a ground reference plane beneath; keep trace lengths under 50 mm when running at 33 MHz to avoid ringing. Place the flash on the same board layer as the host MCU with no vias on the data lines, and add a small ground cutout under the SPI bus only if EMI is a concern. The 8-SOIC (SAE) package has standard JEDEC land pattern recommendations - follow IPC-7351 Class 2 footprint for hand-solder rework.
Do not exceed the absolute maximum VDD of 3.6 V; automotive load-dump transients on a 12 V bus must be clamped with a TVS before reaching this part. Always issue a Read Status Register (0x05) and poll BUSY between Page Program and subsequent accesses - firmware that does not wait for BUSY=0 will read stale data or trigger a write-protect error. The HOLD# pin must be pulled high or driven by the host MCU; leaving it floating can corrupt an in-progress transaction.
When sharing the SPI bus with multiple devices (e.g. an SPI RTC or sensor), ensure only one CS# is asserted at a time and that the inactive CS# lines are pulled high to >0.7 x VDD to avoid leakage into the SST25VF010A. Series 22-33 ohm resistors on SCK/SO close to the driver can dampen ringing on long traces. Refer to the Microchip SPI design guide for bus-loading calculations above four devices.
