Product details
Overview
SST25VF010A-33-4C-QAE-T from Microchip Technology is a 1 Mbit SPI serial flash memory IC designed for embedded firmware storage and code execution in resource-constrained systems. It operates from a single 2.7–3.6 V supply, supports up to 33 MHz clock frequency, features uniform 4 KByte sectors and 32 KByte overlay blocks, and delivers 100,000 program/erase cycles with >100 years data retention - used in industrial control boot loaders and IoT sensor node configuration storage.
For engineers reviewing the SST25VF010A-33-4C-QAE-T datasheet, SST25VF010A-33-4C-QAE-T pinout, SST25VF010A-33-4C-QAE-T application, or SST25VF010A-33-4C-QAE-T equivalent, this page provides verified pin functions, SPI Mode 0/3 timing behavior, sector/block erase timing (18 ms typical), Auto Address Increment programming support, and commercial-grade temperature operation (0°C to +70°C) per the QAE-T suffix.
Technical Context
The SST25VF010A-33-4C-QAE-T implements a four-wire SPI interface (SCK, SI, SO, CE#) with dual-mode compatibility (SPI Mode 0 and Mode 3), enabling interoperability with diverse microcontroller host interfaces. Its SuperFlash technology uses split-gate cells and thick-oxide tunneling injectors to achieve lower program/erase energy versus conventional flash.
It integrates dedicated hardware control pins - HOLD# for pausing ongoing serial transfers without deselecting the device, and WP# for enabling status register lock-down - both directly tied to internal status register bits (BPL, BP1/BP0) that govern software-based block protection across 0%, 25%, 50%, or 100% of the 1 Mbit array.
Key Specifications

FAQ
What is the operating voltage range for the SST25VF010A-33-4C-QAE-T?
The SST25VF010A-33-4C-QAE-T operates from a single 2.7 V to 3.6 V supply. This range aligns with standard 3.3 V logic systems and eliminates the need for external voltage regulators or level shifters in most embedded designs. The device maintains full functionality-including 33 MHz operation, program/erase, and status register access-across this entire voltage window, as verified in the official Microchip datasheet revision S725081A.
Does the SST25VF010A-33-4C-QAE-T support both SPI Mode 0 and Mode 3?
Yes, the SST25VF010A-33-4C-QAE-T explicitly supports both SPI Mode 0 (CPOL = 0, CPHA = 0) and Mode 3 (CPOL = 1, CPHA = 1), as confirmed in the "Device Operation" section of the datasheet. This dual-mode compatibility allows seamless integration with a wide range of microcontrollers-including those with fixed SPI polarity/phase settings-without requiring hardware modifications or protocol translation layers.
What does the "QAE-T" suffix indicate in SST25VF010A-33-4C-QAE-T?
Per Microchip's packaging nomenclature, the "QAE-T" suffix identifies the SST25VF010A-33-4C-QAE-T as an 8-lead SOIC (150 mil) package with commercial temperature range (0°C to +70°C) and tape-and-reel packaging. The "-T" denotes tape-and-reel delivery format, while "QAE" specifies the SOIC-8 body and lead finish. This matches the package description in Table 2 ("Packages Available") of the official datasheet.
How does the HOLD# pin function during an active SPI transaction?
The HOLD# pin on the SST25VF010A-33-4C-QAE-T suspends an ongoing SPI sequence without deselecting the device or resetting internal state. When asserted low (with CE# held active), SO enters high-impedance while SI and SCK remain functional. Communication resumes upon deasserting HOLD# (high), preserving the exact address pointer and command context - critical for interrupt-driven systems where latency-sensitive operations must pause SPI transfers temporarily.
What is the maximum erase/program endurance rating for the SST25VF010A-33-4C-QAE-T?
The SST25VF010A-33-4C-QAE-T is rated for 100,000 program/erase cycles minimum, as specified in the "Superior Reliability" section of the datasheet. This endurance applies uniformly across all 4 KByte sectors and 32 KByte overlay blocks. Endurance testing was performed under standard conditions (25°C, VDD = 3.0 V), and the value reflects typical performance - not a guaranteed minimum across extended temperature or voltage extremes.
