Overview
SST26VF016-80-5I-S2AE from Microchip Technology is a 16 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 30 erasable overlay blocks, and is qualified for industrial temperature range (−40°C to +85°C). It serves in embedded boot code storage for portable electronics including GPS modules and Bluetooth headsets.
For engineers reviewing the SST26VF016-80-5I-S2AE datasheet, SST26VF016-80-5I-S2AE pinout, SST26VF016-80-5I-S2AE application, or SST26VF016-80-5I-S2AE equivalent, key selection considerations include its SQI vs. SPI mode flexibility, 256-byte page programming, 100,000-cycle endurance, OTP Security ID, and dual-package availability (SOIC-8 / WSON-8).
Technical Context
The SST26VF016-80-5I-S2AE implements a 4-bit multiplexed serial interface (SIO[3:0]) supporting both legacy SPI (Mode 0/3) and high-throughput SQI protocols, enabling up to 4× bandwidth over standard SPI at identical clock rates. Its SuperFlash® technology uses split-gate cells and thick-oxide tunneling to achieve fast erase (18 ms sector/block, 35 ms chip) and program (1 ms/page) times while maintaining >100-year data retention.
It integrates a configurable Block-Protection Register (48-bit for SST26VF016) with per-block write-lock and parameter-block read-lock capability, plus Write-Protection Lock-Down (LPBR) and 256-bit Security ID (64-bit factory-unique + 192-bit user-programmable), all accessible via standardized command set including EQIO, RSTQIO, and Read Burst with wrap-around.

| VDD | Power Supply | Primary 2.7–3.6 V supply; powers internal logic, charge pumps, and I/O buffers - decoupling capacitor required near pin. |
| VSS | Ground | Reference return path for all internal circuits and I/O signals - must be low-impedance connection to system ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Index Jump addressing | Enables relative address access (page/block/block-index) to reduce command overhead and improve random-read efficiency in firmware update routines. |
| Write-Suspend capability | Allows interruption of active program/erase operations to service higher-priority reads, improving real-time responsiveness in multitasked embedded systems. |
| Flexible block protection | Configurable lock bits for 4 KByte sectors, 8/32/64 KByte overlay blocks, and parameter regions - supports secure boot partitioning and field-upgrade isolation. |
| Security ID with lockout | 256-bit OTP space (64-bit unique ID + 192-bit user field) that can be permanently locked (SEC bit = 1) to prevent tampering with device identity or cryptographic keys. |
| Burst Read with wrap | Configurable 8/16/32/64-byte linear bursts with automatic address wrap - simplifies streaming of constant tables or audio buffers without software address management. |
| SuperFlash® technology | Split-gate cell architecture delivers faster erase/program, lower power consumption, and superior reliability versus conventional floating-gate flash. |

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 W25Q16JVSIQ | 16 Mbit SPI-only (no native SQI); 133 MHz max clock; Quad Enable bit required to activate QIO mode. | Lacks Index Jump and Write-Suspend; uses standard SFDP for JEDEC ID detection instead of dedicated J-ID commands. | Select when legacy SPI compatibility is prioritized over SQI bandwidth and advanced command features. |
| Cypress S25FL116K0XMFI011 | 16 Mbit, 85 MHz, supports both SPI and Quad SPI (QSPI); includes hardware reset pin and deeper security register set. | No Security ID OTP space; different block protection granularity (uniform 4 KB only); no Page-Index jump capability. | Prefer when hardware reset signaling and broader AEC-Q100 qualification (automotive grade) are required over field-programmable ID and flexible burst addressing. |
Compared with SST26VF016-80-5I-S2AE, W25Q16JVSIQ offers higher clock speed but lacks SQI-native protocol and Index Jump, while S25FL116K0XMFI011 adds automotive qualification and hardware reset but omits OTP Security ID and fine-grained parameter block locking - making SST26VF016-80-5I-S2AE optimal for cost-sensitive, feature-rich industrial boot memory where firmware agility and identity binding matter.

FAQ
What is the maximum clock frequency supported by SST26VF016-80-5I-S2AE in SQI mode?
The SST26VF016-80-5I-S2AE supports up to 80 MHz in SQI mode, delivering a sustained data rate of 320 Mbit/s. This frequency is validated under industrial temperature conditions (−40°C to +85°C) and requires proper signal integrity layout - including controlled impedance traces and minimized stub lengths - to maintain timing margins. The "80" in the part number explicitly denotes this maximum rated speed.
Does SST26VF016-80-5I-S2AE support both SPI and SQI protocols simultaneously?
No, SST26VF016-80-5I-S2AE does not operate in both protocols simultaneously. It powers up in SPI mode (Mode 0 or 3) and transitions to SQI mode only after issuing the EQIO command (0x38). To revert, the RSTQIO command (0xFF) resets it back to SPI. The interface mode is mutually exclusive and controlled entirely by command state, not hardware pin strapping.
How many erasable blocks does SST26VF016-80-5I-S2AE contain, and what are their sizes?
The SST26VF016-80-5I-S2AE contains 30 erasable overlay blocks: four 8 KByte top parameter blocks, four 8 KByte bottom parameter blocks, two 32 KByte overlay blocks (one top, one bottom), and sixteen 64 KByte uniform blocks. Additionally, the memory array includes 512 uniform 4 KByte sectors - totaling 2 MBytes of addressable space with flexible, non-uniform erase granularity.
Can the Security ID in SST26VF016-80-5I-S2AE be reprogrammed after initial programming?
No, the Security ID in SST26VF016-80-5I-S2AE cannot be reprogrammed once locked. The 64-bit factory-programmed segment is permanently fixed. The 192-bit user-programmable segment may be written once using the Program SID (0xA5) command, then permanently locked via Lockout SID (0x85), setting SEC bit = 1 in the Status Register. After lockout, no further writes - including erase - are possible to any portion of the Security ID space.
What is the purpose of the Write-Suspend feature in SST26VF016-80-5I-S2AE?
The Write-Suspend feature in SST26VF016-80-5I-S2AE allows an active program or erase operation to be temporarily halted (using B0H command) so the host controller can perform urgent reads from other memory regions. This prevents blocking of time-critical tasks - such as real-time sensor sampling or communication interrupts - while background flash operations continue. Resume (30H) restores the suspended operation without data loss or reinitialization.
