Product details
Overview
SST26VF016BT-80E/SM from Microchip Technology is a 16 Mbit Serial Quad I/O™ (SQI™) flash memory IC designed for high-speed, low-power embedded code storage and data logging. It operates from 2.3–3.6 V, supports 80 MHz max clock frequency in extended voltage range, features uniform 4 KByte sectors and flexible block protection, and is qualified for industrial temperature range (−40°C to +85°C) in an 8-contact WDFN (6 mm × 5 mm) package.
For engineers reviewing the SST26VF016BT-80E/SM datasheet, SST26VF016BT-80E/SM pinout, SST26VF016BT-80E/SM application, or SST26VF016BT-80E/SM equivalent, key selection criteria include SQI vs. SPI mode compatibility, write-suspend capability, OTP Security ID support, sector/block erase granularity, and hardware write-protection via WP# pin with lock-down options.
Technical Context
The SST26VF016BT-80E/SM implements a six-wire, 4-bit multiplexed I/O interface supporting both legacy SPI (x1/x2) and high-throughput SQI (x4) protocols with Mode 0/Mode 3 clock polarity compatibility. Its SuperFlash® technology uses split-gate cells and thick-oxide tunneling for enhanced endurance and retention.
It integrates dual-mode serial interface logic, a 48-bit Block-Protection Register (BPR), non-volatile Write-Lock Lock-Down register (nVWLDR), 2 KByte OTP Security ID space with factory-programmed 64-bit unique ID, and configurable hold/suspend/resume functionality for concurrent memory access during active program/erase operations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (2 MByte) organized as thirty 64 KByte blocks, two 32 KByte overlay blocks, eight 8 KByte parameter blocks, and uniform 4 KByte sectors. |
| Interface Protocol | Supports SPI x1/x2 and SQI x4 modes; initial power-on state is SPI; EQIO command enables quad I/O for 4× throughput at same clock frequency. |
| Max Clock Frequency | 80 MHz (at 2.3–3.6 V supply); enables up to 40 MB/s read bandwidth in SQI mode - critical for fast boot and firmware update latency reduction. |
| Endurance & Retention | 100,000 program/erase cycles minimum; >100 years data retention - suitable for long-lifecycle industrial control and automotive ECUs. |
| Erase Granularity | Uniform 4 KByte sectors; 8/32/64 KByte blocks; chip erase in 35 ms typical - allows precise firmware partitioning and field-upgrade safety. |

Pinout & Package
Package: 8-contact WDFN (6 mm × 5 mm), RoHS-compliant, industrial temperature grade (−40°C to +85°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CE# | Chip Enable | Active-low device select; must remain low throughout command sequence; controls SPI/SQI transaction boundary. |
| SIO0 (SI) | Serial Data Input | Default SPI input pin; latched on rising SCK edge; reconfigured as bidirectional SIO[3:0] in SQI mode after EQIO command. |
| SIO1 (SO) | Serial Data Output | Default SPI output pin; driven on falling SCK edge; shares physical pin with SO in SPI mode; becomes SIO1 in SQI mode. |
| SIO2 (WP#) | Write Protect / Quad I/O | In SPI mode: hardware write-protection control (with WPEN/IOC bits); in SQI mode: bidirectional data line SIO2. |
| SIO3 (HOLD#) | Hold / Quad I/O | In SPI mode: pauses ongoing serial transfer without reset; in SQI mode: bidirectional data line SIO3; disabled in SQI mode per datasheet. |
| SCK | Serial Clock | Provides timing reference; commands/addresses/data latched on rising edge; output data shifted on falling edge. |
| VDD | Power Supply | 2.3–3.6 V single supply; powers core logic and I/O buffers; decoupling required per layout guidelines. |
| VSS | Ground | Reference return path for all internal circuits and I/O signals; requires low-impedance connection to system ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Quad I/O Interface | Enables 4× data throughput vs. standard SPI at identical clock rate - reduces boot time and firmware update duration in resource-constrained MCUs. |
| Write-Suspend Capability | Allows interruption of active program/erase to service higher-priority reads - essential for real-time systems requiring deterministic response latency. |
| Flexible Block Protection | Independent software lock-down per 8/32/64 KByte block plus permanent OTP lock bits - secures bootloader, calibration data, and configuration parameters against corruption. |

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 W25Q16JVSNIQ | 16 Mbit SPI-only (no SQI), 133 MHz max, 100K endurance, same 8-pin SOIC/WSON packages. | Lacks SQI interface and write-suspend; no OTP Security ID; simpler protection scheme (no nVWLDR). | Select when SQI bandwidth is unnecessary and cost-sensitive SPI compatibility suffices. |
| Cypress S25FL116K0XMFI011 | 16 Mbit SPI flash with 104 MHz max, 100K endurance, 4-KB sectors, but no SQI or Security ID; supports XIP with prefetch buffer. | No quad I/O or hardware security features; optimized for execute-in-place (XIP) over raw throughput. | Prefer for MCU-based systems requiring direct code execution from flash with minimal latency. |
Compared with SST26VF016BT-80E/SM, W25Q16JVSNIQ offers higher SPI clock speed but omits SQI acceleration and security ID, while S25FL116K0XMFI011 prioritizes XIP performance over programmable protection and suspend capability - making SST26VF016BT-80E/SM uniquely suited for secure, real-time, low-power embedded firmware storage.

FAQ
What is the maximum clock frequency supported by the SST26VF016BT-80E/SM?
The SST26VF016BT-80E/SM supports up to 80 MHz maximum clock frequency when operating within the 2.3–3.6 V supply range. This applies to both SPI and SQI modes and is validated for the industrial temperature range (−40°C to +85°C). The 80 MHz limit reflects derating for extended voltage operation, distinct from the 104 MHz maximum available at 2.7–3.6 V.
Does the SST26VF016BT-80E/SM support Quad I/O mode out of reset?
No, the SST26VF016BT-80E/SM powers up in standard SPI mode (x1/x2) by default. Quad I/O mode must be explicitly enabled using the EQIO (38H) command. The IOC bit in the Configuration Register must also be set to '1' before issuing SQI-specific instructions like SQOR or SQIOR. Failure to configure these registers results in invalid command responses.
How does hardware write protection work on the SST26VF016BT-80E/SM?
Hardware write protection on the SST26VF016BT-80E/SM is controlled by the WP# pin in conjunction with the WPEN and IOC bits in the Configuration Register. When IOC = 0 and WPEN = 1, asserting WP# low disables writes to the Block-Protection and Configuration Registers only. The factory default sets WPEN = 0, disabling WP# functionality until explicitly enabled - preventing accidental lockout during system integration.
Can the SST26VF016BT-80E/SM suspend an ongoing erase or program operation?
Yes, the SST26VF016BT-80E/SM supports write-suspend via the WRSU (B0H) command. This allows pausing an active sector/block/chip erase or page program to perform a high-priority read from another memory region. Suspension status is reported in the Status Register (WSE/WSP bits), and resumed using WRRE (30H). This feature is critical for real-time systems requiring deterministic interrupt response.
What is the purpose of the Security ID feature in the SST26VF016BT-80E/SM?
The SST26VF016BT-80E/SM includes a 2 KByte Security ID (Sec ID) space comprising a factory-programmed 64-bit unique identifier and a user-programmable area. It supports PSID (A5H) and LSID (85H) commands to write and permanently lock the user section. Once locked, no further writes are possible - enabling secure device authentication, firmware binding, and anti-counterfeiting in regulated applications.
