Product details
Overview
SST25VF010A-33-4C-SAE from Microchip Technology is a 1 Mbit SPI serial flash memory IC with SuperFlash technology, operating at 2.7–3.6 V, supporting up to 33 MHz clock frequency, featuring uniform 4 KByte sectors and 32 KByte overlay blocks, and used for firmware storage in embedded microcontroller systems.
For engineers reviewing the SST25VF010A-33-4C-SAE datasheet, SST25VF010A-33-4C-SAE pinout, SST25VF010A-33-4C-SAE application, or SST25VF010A-33-4C-SAE equivalent, key selection criteria include SPI Mode 0/3 compatibility, industrial temperature range (−40°C to +85°C), 100,000 program/erase endurance, software/hardware write protection, and SOIC-8 package footprint.
Technical Context
The SST25VF010A-33-4C-SAE implements a four-wire SPI interface (SCK, SI, SO, CE#) with dual-mode support (Mode 0 and Mode 3), enabling interoperability with diverse host controllers. Its split-gate SuperFlash cell architecture delivers faster erase times (sector/block: 18 ms typ.) and lower total energy per operation versus conventional flash.
It integrates dedicated control pins HOLD# for suspend/resume of serial sequences without chip deselection and WP# for hardware-enabled lock-down of status register bits BP0/BP1/BPL. Internal address auto-increment during AAI programming reduces sequential byte-program overhead.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 Mbit (128 KByte), organized as 32 × 4 KByte sectors or 4 × 32 KByte overlay blocks - defines firmware partitioning granularity and update flexibility. |
| Supply Voltage | 2.7–3.6 V - compatible with 3.3 V logic systems and tolerant of brown-out conditions down to 2.7 V. |
| Max Clock Frequency | 33 MHz - enables high-speed read throughput via High-Speed-Read (0BH) command, critical for boot-time latency reduction. |
| Endurance | 100,000 program/erase cycles (typ.) - supports field firmware updates over product lifetime in industrial applications. |
| Data Retention | >100 years - ensures long-term reliability of stored configuration or calibration data without refresh. |
| Operating Temp | −40°C to +85°C (Industrial grade) - validated for deployment in automotive ECUs, industrial PLCs, and outdoor IoT gateways. |
| Active Read Current | 7 mA (typ.) - enables low-power operation during active firmware fetch, reducing system-level power budget impact. |
Pinout & Package
Package: 8-lead SOIC (150 mil body width), RoHS-compliant, lead-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CE# | Chip Enable | Active-low device select; must remain low throughout command sequence - determines SPI slave selection timing and bus arbitration behavior. |
| SO | Serial Data Output | Tri-state output driven on SCK falling edge - provides read data, status register contents, or ID bytes with precise timing alignment. |
| WP# | Write Protect | Hardware enable for BPL bit lock-down; when low, prevents modification of BP0/BP1 unless BPL=0 - adds physical layer security for critical firmware regions. |
| VSS | Ground | Reference return path for all I/O and core logic - requires low-impedance PCB connection to minimize noise coupling into SPI signaling. |
| VDD | Power Supply | 2.7–3.6 V supply input - must be decoupled locally with ≥0.1 µF ceramic capacitor to sustain transient current demands during erase/program. |
| HOLD# | Hold | Active-low suspend signal; pauses ongoing SPI transaction without resetting internal state - enables multi-master arbitration or debug interrupt handling. |
| SCK | Serial Clock | Input clock synchronized to Mode 0 (SCK idle low) or Mode 3 (SCK idle high) - defines sampling edge (rising) and output edge (falling) for SI/SO timing compliance. |
| SI | Serial Data Input | Command, address, or data input latched on SCK rising edge - accepts opcodes (e.g., 03H for Read, 02H for Byte-Program) and payload with MSB-first ordering. |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash Technology | Split-gate cell with thick-oxide tunneling injector enables 18 ms sector erase (vs. >100 ms in standard NOR), reducing firmware update time by >80%. |
| Auto Address Increment (AAI) | Eliminates repeated address transmission during sequential byte programming - cuts total programming time by ~40% vs. standard Byte-Program mode. |
| Dual SPI Mode Support | Native compatibility with both Mode 0 and Mode 3 eliminates need for level-shifting or protocol translation in mixed-vendor controller environments. |
| Flexible Block Protection | BP0/BP1 bits configure 0%, 25%, 50%, or 100% memory array write protection; BPL bit locks protection settings permanently when WP# is asserted. |
| End-of-Write Detection | Software-pollable BUSY bit in status register (bit 0) allows deterministic wait-loop implementation without fixed timeout delays. |
Applications
| Firmware Storage in MCU Bootloader | Configuration Data Storage in Industrial Sensors |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPI serial flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Winbond W25Q80DVSSIG | 8 Mbit density, 104 MHz Dual/Quad SPI, 3 V only (2.7–3.6 V), no HOLD# pin, different status register layout. | Higher density and speed suit complex firmware; lacks HOLD# limits use in multi-master debug scenarios. | Select when needing >1 Mbit capacity and faster Quad SPI interface; verify host driver compatibility with non-SST status register mapping. |
| Macronix MX25L8006EM1I-12G | 8 Mbit density, 86 MHz max clock, 2.7–3.6 V, includes QE bit for Quad mode, same SOIC-8 package, no AAI programming. | Better raw bandwidth but no Auto Address Increment - increases programming time for large sequential writes. | Prefer for high-throughput read-heavy applications; avoid if legacy AAI-based firmware update routines are deployed. |
Compared with SST25VF010A-33-4C-SAE, the Winbond and Macronix alternatives offer higher density and faster clocks but omit HOLD# or AAI - making SST25VF010A-33-4C-SAE uniquely suitable for resource-constrained industrial designs requiring suspend-capable SPI and deterministic low-overhead programming.
