Product details
Overview
SST26VF016BT-80E/SN from Microchip Technology is a 16 Mbit Serial Quad I/O (SQI) flash memory IC operating at 2.3–3.6 V, supporting 80 MHz max clock frequency, 4 KByte uniform sectors, and 100,000 program/erase cycles with >100-year data retention. It serves as nonvolatile code/data storage in microcontroller boot systems requiring high-speed, low-pin-count serial interfaces.
For engineers reviewing the SST26VF016BT-80E/SN datasheet, SST26VF016BT-80E/SN pinout, SST26VF016BT-80E/SN application, or SST26VF016BT-80E/SN equivalent, key selection criteria include SQI/x4 SPI interface support, industrial temperature range (–40°C to +85°C), WDFN-8 package dimensions (6 mm × 5 mm), and hardware write protection via WP# pin with OTP Security ID.
Technical Context
The SST26VF016BT-80E/SN implements a six-wire, 4-bit multiplexed I/O interface (SIO[3:0]) compatible with both traditional SPI (x1/x2 modes) and high-speed SQI protocol, enabling up to 4× throughput versus standard SPI at identical clock rates. Its SuperFlash® split-gate cell architecture delivers faster erase (18 ms sector, 35 ms chip) and lower active current (15 mA @ 80 MHz) than conventional NOR flash.
It features dual protection layers: volatile Block-Protection Register (BPR) with lock-down capability and non-volatile Write-Lock Lock-Down Register (nVWLDR), plus factory-programmed 64-bit unique ID and user-programmable 2 KByte Security ID space. The device defaults to SPI mode at power-up and requires EQIO command to enable SQI operation.

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 W25Q16JVSIM | 16 Mbit SPI-only (no SQI); 133 MHz max; 4 KByte sectors; no OTP Security ID | Lacks quad I/O performance boost and hardware-secured identity; requires external authentication logic | Choose when SQI bandwidth is unnecessary and cost sensitivity outweighs security and speed advantages |
| Cypress S25FL116K0XMFI011 | 16 Mbit SPI/x2; 104 MHz max; 4 KByte sectors; no nVWLDR or factory ID; supports HyperBus in pin-compatible variant | Missing write-suspend, OTP ID, and non-volatile lock-down; broader temperature option but no AEC-Q100 grade | Prefer when migrating from legacy Cypress designs or when HyperBus compatibility is required in future roadmap |
Compared with W25Q16JVSIM and S25FL116K0XMFI011, the SST26VF016BT-80E/SN uniquely combines SQI bandwidth, OTP Security ID, write-suspend, and AEC-Q100 qualification - making it optimal for secure, real-time, automotive-grade firmware storage where deterministic latency and hardware-rooted identity are mandatory.

FAQ
What interface protocols does the SST26VF016BT-80E/SN support?
The SST26VF016BT-80E/SN supports both traditional SPI (x1/x2 modes) and high-speed Serial Quad I/O (SQI) protocol using the same SIO[3:0] pins. It operates in Mode 0 and Mode 3 clock polarity configurations. After power-on reset, it defaults to SPI mode; the EQIO command (0x38) must be issued to enable SQI functionality. All instructions are documented in the DS20005262F datasheet, including SQOR, SQIOR, and RBSQI for optimized quad-speed operations.
Does the SST26VF016BT-80E/SN include hardware write protection?
Yes, the SST26VF016BT-80E/SN includes hardware write protection via the WP# pin, which functions in SPI single-bit and dual-bit read modes when the WPEN bit in the Configuration register is set to '1' and the IOC bit is '0'. This protection applies only to the Block-Protection and Configuration registers-not the main memory array. The default factory setting has WPEN = '0', disabling WP# at power-up; it must be explicitly enabled via WRSR instruction to activate hardware protection.
What is the purpose of the HOLD# pin on the SST26VF016BT-80E/SN?
The HOLD# pin on the SST26VF016BT-80E/SN temporarily suspends active SPI serial communication without resetting internal state or clocking sequence. It operates only in SPI single-bit and dual-bit read modes (not in SQI mode) and requires CE# to be low. When asserted (low), SO enters high-impedance while SI and SCK remain valid. HOLD# is enabled by default at power-up (IOC = '0') and must be tied high if unused. It is commonly used to prioritize interrupt servicing during flash reads.
How does the Security ID feature work in the SST26VF016BT-80E/SN?
The SST26VF016BT-80E/SN includes a 2 KByte Security ID (Sec ID) space comprising a factory-programmed 64-bit unique identifier (read-only, unchangeable) and a user-programmable area. The PSID command (0xA5) writes to the user area; the LSID command (0x85) permanently locks the entire Sec ID space against further writes. Once locked, the SEC bit in the Status register becomes '1' and cannot be reset. This provides hardware-rooted device identity for secure boot and anti-cloning applications.
What erase block sizes are supported by the SST26VF016BT-80E/SN?
The SST26VF016BT-80E/SN supports uniform 4 KByte sectors and multiple overlay block sizes: eight 8 KByte parameter blocks, two 32 KByte overlay blocks, and thirty 64 KByte overlay blocks. Sector Erase (20H) targets 4 KByte regions; Block Erase (D8H) selects 8/32/64 KByte blocks based on address bits A13–A16; Chip Erase (C7H) clears the full 16 Mbit array. This flexible hierarchy enables precise firmware partitioning and minimizes erase time for partial updates.
