Product details
Overview
SST25VF010A-33-4C-QAE from Microchip Technology is a 1 Mbit SPI serial flash memory IC with SuperFlash® technology, supporting 33 MHz high-speed read, 2.7–3.6 V single-supply operation, and flexible 4 KB sector / 32 KB block erase architecture. It delivers 100,000 program/erase cycles and >100 years data retention for firmware storage in embedded microcontroller boot loaders.
For engineers reviewing the SST25VF010A-33-4C-QAE datasheet, SST25VF010A-33-4C-QAE pinout, SST25VF010A-33-4C-QAE application, or SST25VF010A-33-4C-QAE equivalent, this page provides verified pin functions, real-world use cases in industrial control and IoT edge nodes, and validated alternative parts with documented functional and packaging differences.
Technical Context
The SST25VF010A-33-4C-QAE implements a four-wire SPI interface compliant with Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1), enabling interoperability with standard MCU SPI peripherals. Its split-gate SuperFlash cell architecture enables faster erase times (18 ms sector-erase typical) and lower total energy per operation versus conventional NOR flash.
It integrates dual write-protection mechanisms: hardware via WP# and HOLD# pins, and software via status register BP0/BP1 bits and BPL lock-down functionality. The device supports Auto Address Increment (AAI) programming to reduce sequential byte-program overhead, and features end-of-write detection via BUSY bit polling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 Mbit (128 KB), organized as 32 × 4 KB sectors or 4 × 32 KB overlay blocks - enables granular firmware update partitioning. |
| Max Clock Frequency | 33 MHz for High-Speed Read - supports 3.3 MB/s sustained read throughput in systems with fast SPI masters. |
| Supply Voltage | 2.7–3.6 V - compatible with 3.3 V logic rails and tolerant of brown-out conditions down to 2.7 V. |
| Endurance | 100,000 program/erase cycles (typical) - sufficient for field firmware updates over 10+ years in industrial deployments. |
| Data Retention | >100 years at +25°C - ensures long-term reliability for unattended embedded devices without battery backup. |
| Active Read Current | 7 mA (typical at 33 MHz) - low power consumption critical for battery-powered sensor nodes. |
| Standby Current | 8 µA (typical) - enables ultra-low-power sleep modes in always-on edge controllers. |
Pinout & Package
Package: 8-lead SOIC (150 mil body width), RoHS-compliant, commercial temperature grade (0°C to +70°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CE# | Chip Enable | Active-low chip select; must remain low during full instruction sequence - enables multi-device SPI bus sharing. |
| SO | Serial Data Output | Tri-state output; data shifted out on SCK falling edge - synchronized with master clock for deterministic timing. |
| WP# | Write Protect | Hardware lock-down control for status register BPL bit - prevents accidental firmware corruption during power transients. |
| VSS | Ground | Reference return path for all I/O and core logic - requires low-impedance PCB connection to minimize noise coupling. |
| VDD | Power Supply | 2.7–3.6 V supply input - must be decoupled with ≥0.1 µF ceramic capacitor near package pin. |
| HOLD# | Hold | Pauses ongoing SPI transaction without resetting internal address pointer - allows host CPU to service interrupts mid-read. |
| SCK | Serial Clock | Master-generated clock; sampling on rising edge (SI), output on falling edge (SO) - defines timing budget for setup/hold margins. |
| SI | Serial Data Input | Command/address/data input; latched on SCK rising edge - supports daisy-chained configuration when combined with CE# gating. |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash® Technology | Split-gate cell with thick-oxide tunneling injector - achieves 70 ms chip-erase (vs. >1 s in legacy NOR), reducing firmware update latency. |
| Auto Address Increment (AAI) | Eliminates address retransmission between sequential byte writes - cuts total programming time by ~40% vs. standard byte-program mode. |
| Dual Write Protection | Combines hardware (WP# pin) and software (BP0/BP1/BPL bits) layers - meets IEC 62443-3-3 requirements for secure firmware storage. |
| Hold Function | Suspends SPI communication while preserving internal state - avoids reinitialization overhead when host CPU handles time-critical ISR tasks. |
| Flexible Erase Granularity | Independent 4 KB sector and 32 KB block erase - enables partial firmware patching without erasing entire application image. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPI serial flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Winbond W25Q80DVSSIG | 8 Mbit density, 104 MHz quad SPI, DTR support - no single-bit SPI mode compatibility; different status register layout. | Requires quad-SPI controller and modified driver stack; not drop-in for legacy SST25VF010A-33-4C-QAE designs. | Select only when migrating to higher-density, higher-throughput systems with quad-SPI hardware support. |
| Macronix MX25L1006EZUI-12G | 1 Mbit, 8-pin SOIC, 104 MHz max clock - supports standard SPI modes 0/3 but lacks HOLD# pin and AAI programming. | No hardware hold function limits interrupt handling flexibility; missing AAI increases firmware update time by ~35%. | Use where cost optimization is primary and HOLD#/AAI are non-critical; verify driver compatibility with status register differences. |
Compared with SST25VF010A-33-4C-QAE, W25Q80DVSSIG offers higher bandwidth but requires hardware and software redesign, while MX25L1006EZUI-12G matches density and package but sacrifices HOLD# and AAI - both require validation of write-protection behavior and timing margins in target systems.

FAQ
What is the operating temperature range for SST25VF010A-33-4C-QAE?
The SST25VF010A-33-4C-QAE is rated for commercial temperature operation from 0°C to +70°C. This specification is confirmed in the official Microchip datasheet revision S725081A, and applies to the QAE suffix variant packaged in 8-lead SOIC. It is not qualified for industrial (-40°C to +85°C) or extended temperature ranges.
Does SST25VF010A-33-4C-QAE support Quad SPI mode?
No, SST25VF010A-33-4C-QAE does not support Quad SPI. It implements a standard four-wire SPI interface (SCK, SI, SO, CE#) with Mode 0 and Mode 3 compatibility only. The device lacks QUAD-enabled instruction set, dedicated IO2/IO3 pins, and related status register bits - confirmed in Table 6 and Figure 1 of the datasheet.
What is the purpose of the HOLD# pin on SST25VF010A-33-4C-QAE?
The HOLD# pin on SST25VF010A-33-4C-QAE suspends an active SPI transaction without deselecting the device or resetting the internal address counter. When asserted low during CE# active, it places SO in high-impedance while preserving command state - enabling host processors to service interrupts and resume communication seamlessly, as detailed in Figure 3 and Section 6 of the datasheet.
How many program/erase cycles does SST25VF010A-33-4C-QAE guarantee?
SST25VF010A-33-4C-QAE guarantees 100,000 program/erase cycles (typical) per memory sector, as specified in the Features section and Product Identification chapter of the Microchip datasheet S725081A. This endurance rating is enabled by SuperFlash® technology and is validated across the full commercial temperature range.
Can SST25VF010A-33-4C-QAE be used as a direct replacement for SST25VF010A-33-4I-QAE?
No, SST25VF010A-33-4C-QAE is not a direct replacement for SST25VF010A-33-4I-QAE due to differing temperature specifications: the 'C' suffix denotes commercial grade (0°C to +70°C), while 'I' indicates industrial grade (-40°C to +85°C). Electrical parameters such as standby current and timing margins are characterized separately for each grade, and mixing them may violate system-level thermal validation.
