Product details
Overview
SST26VF032-80-5I-QAE from Microchip Technology is a 32 Mbit Serial Quad I/O™ (SQI™) flash memory IC designed for high-speed, low-pin-count code storage and execute-in-place (XIP) applications. It operates at 2.7–3.6 V, supports 80 MHz clock frequency, delivers 320 Mbit/s sustained data rate, and features uniform 4 KByte sectors with 62 total erasable blocks - used in portable electronics requiring compact, reliable nonvolatile storage.
For engineers reviewing the SST26VF032-80-5I-QAE datasheet, SST26VF032-80-5I-QAE pinout, SST26VF032-80-5I-QAE application, or SST26VF032-80-5I-QAE equivalent, key selection considerations include SQI vs. SPI mode compatibility, 8-contact WSON (6 mm × 5 mm) package constraints, industrial temperature range (−40°C to +85°C), write-suspend capability for real-time multitasking, and Security ID programmability for firmware authentication.
Technical Context
The SST26VF032-80-5I-QAE implements a 4-bit multiplexed serial interface (SIO[3:0]) supporting both Mode 0 and Mode 3 SPI-compatible operation and dedicated SQI protocol via EQIO command. Its SuperFlash® split-gate cell architecture enables 100,000 program/erase cycles and >100-year data retention while reducing active current to 12 mA (typical @ 80 MHz) and standby current to 8 µA.
It integrates a 256-byte page-program buffer, flexible erase hierarchy (4 KByte sectors, eight 8 KByte parameter blocks, two 32 KByte and sixty-two 64 KByte overlay blocks), and dual-layer protection: software block-locking (read/write lock per block) plus Write-Protection Lock-Down (LPBR) to prevent register modification after power cycle.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 32 Mbit (4 MByte) - supports full firmware images for mid-tier microcontrollers without external memory expansion. |
| Interface Protocol | SQI (4-bit multiplexed I/O) and SPI (1-bit SI/SO) - enables backward compatibility and 4× throughput vs. standard SPI at same clock frequency. |
| Max Clock Frequency | 80 MHz - enables XIP execution with sub-100 ns effective read latency when burst-aligned. |
| Erase Endurance | 100,000 cycles - sufficient for field firmware updates over 10+ years in industrial control or networking equipment. |

Key Features
| Feature | Design Value |
|---|---|
| Execute-in-Place (XIP) | Enables direct CPU instruction fetch from flash at 80 MHz - eliminates SRAM shadowing and reduces BOM cost in resource-constrained designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Winbond W25Q32JVSIQ | 32 Mbit, 1.8 V or 3.3 V supply; Quad SPI only (no dual-mode SPI fallback); no Security ID or Index Jump. | Lacks hardware-based security features and advanced addressing modes - suitable for cost-sensitive consumer products without firmware authentication needs. | Select when lower voltage operation (1.8 V) is required and SQI backward compatibility is unnecessary. |
| Cypress S25FL132K0XMFI001 | 32 Mbit, 2.7–3.6 V; supports Dual/Quad SPI but no native SQI protocol; includes 64-bit unique ID (no user-programmable portion). | No Index Jump or Write-Suspend - limits real-time multitasking capability during firmware updates. | Choose when legacy Cypress toolchain integration is prioritized over advanced SQI features and security extensibility. |
Compared with W25Q32JVSIQ and S25FL132K0XMFI001, the SST26VF032-80-5I-QAE uniquely combines SQI/SPI dual-mode operation, Index Jump addressing, 256-bit Security ID with OTP factory ID, and write-suspend - making it optimal for secure, real-time embedded systems where firmware agility and authenticity are critical.

FAQ
What is the primary interface protocol supported by the SST26VF032-80-5I-QAE?
The SST26VF032-80-5I-QAE supports both Serial Peripheral Interface (SPI) and Serial Quad I/O™ (SQI) protocols. At power-on reset, it defaults to SPI mode (SI/SO pins active) for backward compatibility. The EQIO command (0x38) enables SQI mode, activating all four SIO[3:0] lines for 4-bit multiplexed transfers. This dual-mode capability allows seamless migration from legacy SPI designs to higher-throughput SQI without hardware redesign.
Does the SST26VF032-80-5I-QAE support execute-in-place (XIP) operation?
Yes, the SST26VF032-80-5I-QAE supports true execute-in-place (XIP) operation due to its 80 MHz maximum clock frequency and low-latency continuous read modes (High-Speed Read and Read Burst). When configured in SQI mode, it delivers up to 320 Mbit/s sustained data rate - enabling microcontrollers to fetch instructions directly from flash without shadowing to RAM, reducing system memory footprint and power consumption in the SST26VF032-80-5I-QAE-based design.
How many erasable blocks does the SST26VF032-80-5I-QAE contain, and what are their sizes?
The SST26VF032-80-5I-QAE contains 62 total erasable blocks: fifty-eight uniform 64 KByte overlay blocks, two 32 KByte overlay blocks (one top, one bottom), and eight 8 KByte parameter overlay blocks (four top, four bottom). Additionally, the memory array is subdivided into uniform 4 KByte sectors - providing granular erase control ideal for firmware update partitions, configuration storage, and bootloader protection in the SST26VF032-80-5I-QAE implementation.
What security features are integrated into the SST26VF032-80-5I-QAE?
The SST26VF032-80-5I-QAE integrates a 256-bit Security ID (Sec ID) with 64-bit factory-programmed unique identifier and 192-bit user-programmable space, plus hardware-enforced block protection with Lock-Down capability. The Sec ID can be programmed and permanently locked using dedicated commands (A5H and 85H), while the Block-Protection Register (48/80 bits) enables per-block read/write locking - both features are accessible only after issuing Write-Enable (WREN), ensuring authenticated, tamper-resistant firmware storage in the SST26VF032-80-5I-QAE.
Is the SST26VF032-80-5I-QAE compatible with industrial temperature requirements?
Yes, the SST26VF032-80-5I-QAE is rated for industrial temperature operation from −40°C to +85°C, as confirmed by its "I" suffix in the part number and explicit specification in the datasheet. This rating applies across all functional modes - including SQI read/write, erase operations, and Security ID programming - ensuring reliable performance in demanding environments such as automotive infotainment, industrial PLCs, and outdoor GPS equipment using the SST26VF032-80-5I-QAE.
