Product details
Overview
SST25VF010A-33-4I-ZAE from Microchip Technology is a 1 Mbit SPI serial flash memory IC designed for embedded firmware storage and boot code retention in microcontroller-based systems. It operates from a single 2.7–3.6 V supply, supports up to 33 MHz clock frequency, delivers 100,000 program/erase cycles, and guarantees >100 years data retention. It is used in industrial control modules where reliable nonvolatile storage of configuration data and firmware images is required.
For engineers reviewing the SST25VF010A-33-4I-ZAE datasheet, SST25VF010A-33-4I-ZAE pinout, SST25VF010A-33-4I-ZAE application, or SST25VF010A-33-4I-ZAE equivalent, key selection criteria include SPI Mode 0/3 compatibility, industrial temperature range (−40°C to +85°C), 4 KByte sector erase granularity, Auto Address Increment (AAI) programming efficiency, and hardware write protection via WP# and HOLD# pins.
Technical Context
The SST25VF010A-33-4I-ZAE implements a four-wire SPI interface with CE#, SCK, SI, and SO signals, supporting both Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1). Its SuperFlash technology uses a split-gate cell and thick-oxide tunneling injector to achieve superior endurance and data retention over conventional NOR flash.
It features dual erase architectures-uniform 4 KByte sectors and 32 KByte overlay blocks-and supports Byte-Program (14 µs typical), AAI programming, and end-of-write detection via software status register polling. The device includes dedicated HOLD# and WP# pins for real-time serial transaction suspension and hardware-enforced block protection lock-down.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 Mbit (128 KByte), organized as 32 × 4 KByte sectors |
| Interface | SPI-compatible 4-wire serial interface (CE#, SCK, SI, SO); supports Mode 0 and Mode 3 |
| Max Clock Frequency | 33 MHz for High-Speed Read; enables faster firmware loading and OTA update throughput |
| Endurance | 100,000 program/erase cycles - sufficient for field-upgradable embedded applications with frequent configuration writes |
| Data Retention | Greater than 100 years at +25°C - ensures long-term reliability without refresh in unpowered storage |

| Temperature Range | Industrial: −40°C to +85°C - qualified for deployment in motor drives, PLCs, and outdoor IoT gateways |
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 chip select; must remain low during entire command sequence to maintain device engagement |
| SCK | Serial Clock | Timing reference for SPI communication; rising edge latches input (SI), falling edge outputs data (SO) |
| SI | Serial Data Input | Receives opcodes, addresses, and data; MSB-first, synchronized to SCK rising edge |
| SO | Serial Data Output | Transmits read data and status register contents; high-impedance when HOLD# active or CE# high |
| WP# | Write Protect | Hardware enable/disable for Block-Protection Lock-down (BPL); low = BPL bit becomes read-only |
| HOLD# | Hold | Suspends ongoing SPI transfer without resetting internal state; allows host to service higher-priority interrupts |
| VDD | Power Supply | Single 2.7–3.6 V supply; powers core logic and memory array; decoupling capacitor required |
| VSS | Ground | Reference return path for all digital and analog circuitry; must be low-impedance connection |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash Technology | Split-gate cell with thick-oxide tunneling injector enables lower program current and shorter erase time vs. standard NOR flash |
| Auto Address Increment (AAI) | Reduces total programming time by eliminating address retransmission between sequential byte writes |
| Flexible Erase Architecture | Independent 4 KByte sector and 32 KByte block erase options allow precise wear leveling and partial firmware updates |
| Hardware Write Protection | WP# pin controls lock-down of BP1/BP0 bits; prevents accidental corruption of protected boot sectors |
| HOLD# Functionality | Enables non-disruptive pause/resume of SPI transfers - critical for deterministic real-time system response |

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 |
|---|---|---|---|
| AT25DF021A-SSH-T | 2 Mbit density, 85 MHz max clock, deeper power-down mode (1 µA), no HOLD# pin | Lacks hardware hold functionality; requires software-managed transaction interruption | Select when higher speed and density are needed and HOLD# is not required in the host design |
| W25X10CLSNIG | 1 Mbit, 20 MHz max clock, no AAI programming, 10 µA standby, SOIC-8 package | Slower read performance and no AAI support increases firmware update latency | Choose for cost-sensitive designs where 33 MHz timing and AAI acceleration are noncritical |
Compared with AT25DF021A-SSH-T and W25X10CLSNIG, the SST25VF010A-33-4I-ZAE uniquely balances industrial temperature compliance, hardware HOLD#/WP# pins, and AAI programming - making it optimal for real-time embedded systems requiring deterministic SPI control and robust field update capability.

FAQ
What is the maximum SPI clock frequency supported by the SST25VF010A-33-4I-ZAE?
The SST25VF010A-33-4I-ZAE supports up to 33 MHz for High-Speed Read operations using the 0BH command with dummy byte. Standard Read (03H) is rated to 20 MHz. This 33 MHz capability enables faster firmware loading and reduces boot time in resource-constrained microcontroller systems using the SST25VF010A-33-4I-ZAE.
Does the SST25VF010A-33-4I-ZAE support both SPI Mode 0 and Mode 3?
Yes, the SST25VF010A-33-4I-ZAE explicitly supports both SPI Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1), as confirmed in its datasheet. This dual-mode compatibility allows seamless integration with diverse microcontroller SPI peripherals without requiring hardware level-shifting or protocol translation - a key advantage of the SST25VF010A-33-4I-ZAE in heterogeneous design environments.
How does the HOLD# pin function on the SST25VF010A-33-4I-ZAE?
The HOLD# pin on the SST25VF010A-33-4I-ZAE suspends an active SPI transaction without deselecting the device or resetting internal state. When asserted low (with CE# active), SO enters high-impedance and communication pauses until HOLD# is deasserted. This feature is essential for interrupt-driven systems and is a distinguishing capability of the SST25VF010A-33-4I-ZAE versus basic SPI flash alternatives.
What erase granularities does the SST25VF010A-33-4I-ZAE support?
The SST25VF010A-33-4I-ZAE supports three erase types: Chip-Erase (entire 1 Mbit array), Block-Erase (32 KByte uniform blocks), and Sector-Erase (4 KByte uniform sectors). This flexible hierarchy enables efficient wear leveling, partial firmware updates, and targeted configuration clearing - a core design strength of the SST25VF010A-33-4I-ZAE in field-deployed devices.
Is the SST25VF010A-33-4I-ZAE qualified for industrial temperature operation?
Yes, the SST25VF010A-33-4I-ZAE is specified for industrial temperature range: −40°C to +85°C. This qualification is explicitly stated in the "Temperature Range" section of its datasheet and applies to all electrical specifications including timing, endurance, and data retention. The "I" in the part number SST25VF010A-33-4I-ZAE denotes industrial grade, confirming its suitability for harsh-environment applications.
