Product details
Overview
SST26VF032A-80-5I-S2AE 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 with 320 Mbit/s sustained data rate, features uniform 4 KByte sectors and 62 erasable blocks, and is rated for industrial temperature range (–40°C to +85°C). It is used in GPS modules, Bluetooth headsets, and optical disk drives where compact footprint and fast read performance are critical.
For engineers reviewing the SST26VF032A-80-5I-S2AE datasheet, SST26VF032A-80-5I-S2AE pinout, SST26VF032A-80-5I-S2AE application, or SST26VF032A-80-5I-S2AE equivalent, key selection considerations include SQI vs. SPI mode compatibility, 8-contact WSON package constraints, 256-byte page programming latency, block protection register configuration, and Security ID OTP programming workflow.
Technical Context
The SST26VF032A-80-5I-S2AE implements a 4-bit multiplexed serial interface supporting both legacy SPI (Mode 0/3) and proprietary SQI protocol, enabling quad-data-rate transfers without increasing pin count. Its SuperFlash® split-gate cell architecture delivers 100,000 program/erase cycles and >100-year data retention while reducing active and standby current versus conventional NOR flash.
It integrates dedicated command logic for Index Jump (page/block/block-index), burst wrap-around (8/16/32/64 Byte), write-suspend/resume, and dual-layer block protection - including 8×8 KByte parameter overlay blocks, two 32 KByte overlays, and 62×64 KByte uniform blocks - all configurable via software-controlled registers.

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 SPI flash (quad I/O), 104 MHz max clock, no SQI protocol; lacks Index Jump and Write-Suspend | Compatible for basic SPI read/write but not for SQI-optimized XIP or real-time suspend/resume workflows | Select when legacy SPI compatibility is prioritized over SQI bandwidth and advanced command features |
| Cypress S25FL132K0XMFI010 | 32 Mbit FL-S series; supports Dual/Quad SPI, 85 MHz, includes SFDP and 4-KB sector erase only - no parameter overlay blocks or SecID | Valid for general-purpose firmware storage but lacks parameter block flexibility and hardware security ID | Choose when standardized JEDEC SPI and SFDP support are required over SST-specific features like Index Jump |

FAQ
What is the maximum clock frequency supported by the SST26VF032A-80-5I-S2AE?
The SST26VF032A-80-5I-S2AE supports a maximum clock frequency of 80 MHz for High-Speed Read and SQI operations. This enables a sustained data rate of 320 Mbit/s in Quad I/O mode. The "80" in the part number explicitly denotes this 80 MHz rating, verified in the DS-25017A datasheet Section 1. The device also supports SPI-mode reads up to 33 MHz for backward compatibility.
Does the SST26VF032A-80-5I-S2AE support true execute-in-place (XIP) operation?
Yes, the SST26VF032A-80-5I-S2AE supports deterministic execute-in-place (XIP) operation due to its 80 MHz High-Speed Read capability and low-latency SQI interface. The datasheet confirms it enables "minimum latency XIP capability without the need for code shadowing on an SRAM." This is achieved through continuous burst reads and Index Jump addressing, allowing CPU instruction fetch directly from flash with predictable timing.
What package type is used for the SST26VF032A-80-5I-S2AE?
The SST26VF032A-80-5I-S2AE uses an 8-contact WSON (6 mm × 5 mm) package, as confirmed in the DS-25017A datasheet Section 1 and Figure 2. This RoHS-compliant, surface-mount package features exposed pad thermal design and is distinct from the optional 8-lead SOIC variant. Pin assignments match the WSON footprint, including SIO[3:0], SCK, CE#, VDD, and VSS.
How many erasable blocks does the SST26VF032A-80-5I-S2AE contain?
The SST26VF032A-80-5I-S2AE contains 62 uniform 64 KByte erasable blocks, as stated in the datasheet Section 5 ("Memory Organization") and Table 3 footnote. In addition, it includes eight 8 KByte parameter overlay blocks, two 32 KByte overlay blocks, and uniform 4 KByte sectors - totaling 62 primary blocks plus overlays for flexible firmware partitioning.
What security features are implemented in the SST26VF032A-80-5I-S2AE?
The SST26VF032A-80-5I-S2AE implements a 256-bit One-Time Programmable Security ID (SecID) with 64-bit factory-unique identifier and 192-bit user-programmable space. It also supports write-protection lockdown (LPBR command), read-locking of parameter blocks (returning 00H on read), and block-level software protection via the 80-bit Block-Protection Register - all documented in Sections 7–8 of DS-25017A.
