Product details
Overview
SST26VF016B-104V/MF70SVAO from Microchip Technology is a 16 Mbit Serial Quad I/O (SQI) flash memory IC operating at 2.7–3.6 V with 104 MHz max clock frequency, supporting x1/x2/x4 SPI and 4-bit SQI protocols, and featuring uniform 4 KByte sectors, 100,000 write/erase cycles, and industrial temperature range (–40°C to +85°C). It serves as nonvolatile code/data storage in microcontroller boot loaders, firmware update buffers, and embedded system configuration memory.
For engineers reviewing the SST26VF016B-104V/MF70SVAO datasheet, SST26VF016B-104V/MF70SVAO pinout, SST26VF016B-104V/MF70SVAO application, or SST26VF016B-104V/MF70SVAO equivalent, key selection considerations include SQI vs. SPI mode compatibility, 4 KByte sector erase granularity, hardware write-protection via WP# pin, Security ID OTP capability, and WDFN-8 (6 mm × 5 mm) package suitability for space-constrained PCB layouts.
Technical Context
The SST26VF016B-104V/MF70SVAO implements a six-wire, 4-bit multiplexed serial interface (SIO[3:0]) with full backward compatibility to standard SPI Mode 0/3, enabling quad-data-rate transfers without increasing pin count. Its SuperFlash® split-gate CMOS technology delivers faster erase (18 ms sector, 35 ms chip) and lower active current (15 mA @ 104 MHz) versus conventional NOR flash.
It integrates dual protection layers: volatile Block-Protection Register (BPR) with per-block write/read lock control and non-volatile Write-Lock Lock-Down Register (nVWLDR) that permanently fixes protection bits. The device also includes a 2 KByte Security ID area with factory-programmed 64-bit unique identifier and user-programmable segment, locked via LSID command.
Key Specifications

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CE# | Chip Enable | Active-low chip select; must remain low throughout command sequence; controls device activation in multi-flash bus configurations |
| SIO0 (SI) | Serial Data Input | Primary input for commands, addresses, and data in SPI mode; defaults to SI after power-on reset |
| SIO1 (SO) | Serial Data Output | Primary output for read data in SPI mode; defaults to SO after power-on reset |

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 W25Q16JW | 16 Mbit, 133 MHz max, DTR support, no SQI; uses standard SPI quad I/O (QPI) but lacks true 4-bit multiplexed SIO architecture | Lacks native SQI protocol and HOLD#/WP# dual-function pin mapping; requires different driver initialization sequence | Select when higher clock speed (133 MHz) is prioritized over SQI compatibility and when existing QPI firmware stack is in place |
| Cypress S25FL116K | 16 Mbit, 85 MHz max, supports XIP and wrap-around burst; no Security ID or nVWLDR; uses legacy SPI-only interface | No OTP Security ID or permanent lock-down capability; limited to basic code storage without identity binding | Select for cost-sensitive consumer applications where secure identity and field-programmable protection are not required |
Compared with W25Q16JW and S25FL116K, the SST26VF016B-104V/MF70SVAO uniquely combines SQI performance, dual-layer memory protection, and factory-programmed Security ID - making it optimal for automotive and industrial designs demanding secure, upgradable firmware with minimal PCB footprint.

FAQ
What is the maximum operating frequency of the SST26VF016B-104V/MF70SVAO and under what voltage conditions?
The SST26VF016B-104V/MF70SVAO supports a maximum clock frequency of 104 MHz when operated within the 2.7–3.6 V supply range. At the extended 2.3–3.6 V range, the maximum frequency is reduced to 80 MHz. This specification is confirmed in the DS20005262F datasheet Section 1.0 Features and applies to both SPI and SQI modes. The SST26VF016B-104V/MF70SVAO maintains full command compatibility across both voltage ranges, with timing parameters adjusted accordingly.
Does the SST26VF016B-104V/MF70SVAO support true quad I/O mode, and how is it enabled?
Yes, the SST26VF016B-104V/MF70SVAO supports true Serial Quad I/O (SQI) mode using all four SIO[3:0] pins for bidirectional data transfer. SQI mode is enabled by setting the IOC bit (Bit 1) in the Configuration Register to '1' using the WRCR command, followed by issuing the EQIO (38H) command. After this sequence, SIO2 and SIO3 function as I/O lines instead of WP# and HOLD#. The SST26VF016B-104V/MF70SVAO does not enter SQI mode automatically - explicit register and command configuration is required.
How does hardware write protection work on the SST26VF016B-104V/MF70SVAO, and what are its limitations?
Hardware write protection on the SST26VF016B-104V/MF70SVAO is implemented via the WP# pin (SIO2), but only when IOC = 0 and WPEN = 1 in the Configuration Register. In this state, pulling WP# low disables writes to the Block-Protection and Configuration Registers only - it does not protect the main memory array. The SST26VF016B-104V/MF70SVAO's factory default has WPEN = 0, so WP# is disabled at power-up unless explicitly programmed. Permanent protection requires the non-volatile nVWLDR register.
What is the purpose and structure of the Security ID feature in the SST26VF016B-104V/MF70SVAO?
The SST26VF016B-104V/MF70SVAO includes a 2 KByte Security ID (Sec ID) area divided into a factory-programmed 64-bit unique identifier (read-only, unchangeable) and a user-programmable segment. The PSID command writes to the user area; the LSID command permanently locks the entire Sec ID space against further writes. Once LSID is executed, the SEC bit in the Status Register becomes '1' permanently. The SST26VF016B-104V/MF70SVAO uses this feature to establish hardware-rooted device identity for secure boot and authentication workflows.
Can the SST26VF016B-104V/MF70SVAO suspend an ongoing erase or program operation, and how is it managed?
Yes, the SST26VF016B-104V/MF70SVAO supports write-suspend via the WRSU (B0H) command, allowing interruption of sector/block/chip erase or page program operations to service urgent read requests. Suspension is indicated by WSE or WSP bits in the Status Register. Resume is triggered with WRRE (30H). The SST26VF016B-104V/MF70SVAO retains full suspend/resume state across power cycles only if the operation was not completed - however, suspended operations do not survive power loss unless explicitly resumed before shutdown.
