Product details
Overview
SST26VF016B-104I/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 full SQI protocol, 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 and firmware update modules.
For engineers reviewing the SST26VF016B-104I/MF70SVAO datasheet, SST26VF016B-104I/MF70SVAO pinout, SST26VF016B-104I/MF70SVAO application, or SST26VF016B-104I/MF70SVAO equivalent, key selection considerations include SQI vs. SPI mode configuration, sector-level write protection granularity, Security ID OTP programming capability, burst read timing compliance, and WDFN-8 (6 mm × 5 mm) package compatibility with high-density PCB layouts.
Technical Context
The SST26VF016B-104I/MF70SVAO implements a six-wire, 4-bit multiplexed I/O interface (SIO[3:0]) enabling quad-data-rate transfers while maintaining backward compatibility with standard SPI Mode 0/3. Its SuperFlash® split-gate cell architecture delivers faster erase (18 ms sector, 35 ms chip) and lower active current (15 mA @ 104 MHz) versus conventional NOR flash.
It supports flexible protection via volatile Block-Protection Register (48-bit), non-volatile Write-Lock Lock-Down Register (40-bit), and hardware WP#/HOLD# pins-only active in SPI single/dual mode. The device ships with IOC=0 and WPEN=0 by default, requiring explicit configuration to enable SQI or hardware write protection.

The SST26VF016B-104I/MF70SVAO includes a 2 KByte Security ID (Sec ID) space comprising a factory-programmed 64-bit unique identifier (one-time programmable, non-erasable) and a user-programmable segment. Users may program the latter via the PSID (A5H) command, then permanently lock it using LSID (85H). Once locked, neither segment can be altered-ensuring cryptographic key binding and device identity integrity throughout the product lifecycle.
What package type is used for SST26VF016B-104I/MF70SVAO, and what are its key mechanical characteristics?
