Product details
Overview
SST26VF064BA-104I/SM from Microchip Technology is a 64-Mbit Serial Quad I/O™ (SQI™) Flash memory IC designed for high-speed, low-power embedded code storage and data logging. It operates at up to 104 MHz (2.7–3.6 V), supports uniform 4-Kbyte sectors and flexible block protection, and delivers 100,000 program/erase cycles with >100-year data retention. It is used in industrial controllers requiring fast boot code execution and secure firmware updates.
For engineers reviewing the SST26VF064BA-104I/SM datasheet, SST26VF064BA-104I/SM pinout, SST26VF064BA-104I/SM application, or SST26VF064BA-104I/SM equivalent, key selection criteria include quad-I/O burst read performance, OTP Security ID capability, hardware write-protection configuration via WP#/IOC bits, and compatibility with SPI Mode 0/3 timing in both x1/x2/x4 protocols.
Technical Context
The SST26VF064BA-104I/SM implements a six-wire SQI interface (SCK, CE#, SIO[3:0]) enabling 4-bit multiplexed command/address/data transfers, quadrupling throughput versus standard SPI at identical clock frequency. Its SuperFlash® technology uses split-gate cells and thick-oxide tunneling for faster erase (18 ms sector typical) and lower energy per operation.
At power-up, SST26VF064BA defaults with IOC=1 - disabling WP# and HOLD# pins while enabling SIO2/SIO3 for native Quad I/O mode - distinguishing it from SST26VF064B. It supports software-controlled write suspend, configurable burst lengths (8/16/32/64-byte wrap), and dual-mode operation: full SPI command-set compatibility plus dedicated SQI instructions (e.g., 6BH, EBH, 0CH).

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 W25Q64JW-IQ | 64 Mbit, 133 MHz max, octal DTR support, no OTP Security ID, different status register map | Lacks factory-programmed unique ID and permanent lock-down - unsuitable for secure boot or anti-counterfeiting use cases | Select when maximum read bandwidth (octal DTR) is prioritized over security features and legacy SPI compatibility is sufficient |
| Cypress S25FL164K0XMFI001 | 64 Mbit, 85 MHz max, HyperBus interface, no SQI mode, different command set and protection granularity | Requires HyperBus controller; lacks burst wrap and flexible 8-Kbyte parameter blocks - limits firmware partitioning flexibility | Select only for systems already using Cypress HyperFlash ecosystem and where SQI protocol compatibility is not required |
Compared with W25Q64JW-IQ and S25FL164K0XMFI001, the SST26VF064BA-104I/SM uniquely combines 104 MHz SQI performance, OTP Security ID with lockout, and granular 8-Kbyte parameter block protection - making it optimal for secure, long-lifecycle industrial and automotive firmware storage where both speed and tamper resistance are mandatory.

FAQ
What is the default I/O configuration of SST26VF064BA-104I/SM at power-up?
The SST26VF064BA-104I/SM powers up with the IOC bit (Configuration Register bit 1) set to '1', disabling WP# and HOLD# pins while enabling SIO2 and SIO3 for native Quad I/O operation. This distinguishes it from the SST26VF064B variant, which defaults to IOC=0. The configuration is confirmed in DS20005119K Section 4.5.8 and applies directly to the SST26VF064BA-104I/SM.
Does SST26VF064BA-104I/SM support both SPI Mode 0 and Mode 3?
Yes, SST26VF064BA-104I/SM supports both SPI Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1), as specified in DS20005119K Section 4.0. The SCK idle state differs (low in Mode 0, high in Mode 3), but data sampling occurs on the rising edge of SCK for input and driving occurs after the falling edge for output in both modes - ensuring interoperability with diverse host controllers.
How does the Security ID feature work in SST26VF064BA-104I/SM?
The SST26VF064BA-104I/SM includes a 2-Kbyte Security ID space: 64 bits factory-programmed with a unique identifier (non-erasable, non-modifiable) and a user-programmable area. The LSID command permanently locks the entire space, setting the SEC bit in the STATUS register to '1'. Once locked, no further writes are possible - a verified behavior documented in DS20005119K Section 4.3 and Table 4-2.
What is the erase time specification for SST26VF064BA-104I/SM?
SST26VF064BA-104I/SM specifies 18 ms typical (25 ms maximum) for sector or block erase, and 35 ms typical (50 ms maximum) for chip erase - values measured under 2.7–3.6 V conditions and confirmed in DS20005119K Features section and Section 5.0 timing tables. These times reflect SuperFlash® technology's optimized tunneling efficiency.
Is SST26VF064BA-104I/SM qualified for automotive applications?
Yes, SST26VF064BA-104I/SM is explicitly qualified to AEC-Q100 Grade 2 (–40°C to +105°C) and Grade 3 (–40°C to +125°C), as stated in the Features section of DS20005119K. The "I/SM" suffix denotes Industrial Plus temperature grade, aligning with Grade 2 requirements - validated through stress testing per AEC-Q100 Rev G standards.
