Product details
Overview
SST25VF010A-33-4I-SAE-T from Microchip Technology is a 1 Mbit SPI serial flash memory IC designed for embedded firmware storage and boot code retention in space-constrained 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 microcontroller boot loaders requiring reliable, low-pin-count nonvolatile storage.
For engineers reviewing the SST25VF010A-33-4I-SAE-T datasheet, SST25VF010A-33-4I-SAE-T pinout, SST25VF010A-33-4I-SAE-T application, or SST25VF010A-33-4I-SAE-T equivalent, key selection criteria include SPI Mode 0/3 compatibility, 4 KByte sector erase granularity, Auto Address Increment (AAI) programming support, HOLD#/WP# hardware control pins, and industrial temperature range (-40°C to +85°C).
Technical Context
The SST25VF010A-33-4I-SAE-T implements a four-wire SPI interface with CE#, SCK, SI, and SO lines, supporting both Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1) timing. Its SuperFlash technology uses a split-gate cell and thick-oxide tunneling injector to achieve superior endurance and data retention versus conventional 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 software status polling via BUSY/WEL bits. The device includes dedicated HOLD# and WP# pins for real-time serial transaction suspension and hardware-assisted block protection lock-down.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT25DF011-SSH-T | 1 Mbit density, 85 MHz max clock, but requires 2.3–3.6 V supply and lacks HOLD# pin | No hardware hold capability; unsuitable where SPI transaction suspension is required | Select only if higher speed and wider voltage range outweigh need for HOLD# functionality |
| W25X10CLSNIG | 1 Mbit density, 2.7–3.6 V, 80 MHz max clock, but uses different status register layout and no AAI mode | Lacks Auto Address Increment; increases programming time for sequential writes | Prefer when maximum read throughput is critical and write patterns are sparse or random |

FAQ
What is the maximum clock frequency supported by the SST25VF010A-33-4I-SAE-T?
The SST25VF010A-33-4I-SAE-T supports a maximum clock frequency of 33 MHz for High-Speed-Read operations using the 0BH command with a dummy byte. Standard Read (03H) is rated up to 20 MHz. This 33 MHz capability enables faster boot code loading and firmware retrieval in time-critical embedded systems, and is explicitly confirmed in the official Microchip datasheet revision S725081A.
Does the SST25VF010A-33-4I-SAE-T support both SPI Mode 0 and Mode 3?
Yes, the SST25VF010A-33-4I-SAE-T explicitly supports both SPI Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1), as documented in the Product Description and Figure 2 of the datasheet. This dual-mode compatibility ensures interoperability with diverse host microcontrollers and simplifies integration across heterogeneous design platforms without requiring level-shifting or protocol translation.
What is the purpose of the HOLD# pin on the SST25VF010A-33-4I-SAE-T?
The HOLD# pin on the SST25VF010A-33-4I-SAE-T suspends an ongoing SPI transaction without deselecting the device or resetting internal state. When asserted low while CE# is active, it places SO in high-impedance and pauses clock synchronization - allowing external controllers to temporarily halt communication (e.g., during interrupt servicing) and resume seamlessly. This behavior is fully defined in Section 6 of the datasheet.
How does the Auto Address Increment (AAI) feature improve programming efficiency in the SST25VF010A-33-4I-SAE-T?
The AAI feature in the SST25VF010A-33-4I-SAE-T eliminates the need to retransmit the address for each subsequent byte during sequential programming. After issuing the AFH command and first address/data pair, the device auto-increments the address internally - reducing bus overhead and total programming time. This is especially valuable for firmware image writes, and is confirmed in Sections 9 and 13 of the datasheet.
What temperature range is specified for the SST25VF010A-33-4I-SAE-T?
The SST25VF010A-33-4I-SAE-T is rated for the Industrial temperature range of -40°C to +85°C, as stated in the Features section and Product Identification chapter of the datasheet. This specification applies to the "I" suffix in the part number and is validated across electrical parameters including read timing, erase/write endurance, and data retention - making it suitable for demanding environmental deployments.
