Overview
SST26VF064BAT-104I/MF 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 x1/x2/x4 SPI and full SQI protocols, features uniform 4-Kbyte sectors and 64-Kbyte blocks, and delivers 100,000 program/erase cycles with >100-year data retention - deployed in industrial controllers requiring fast boot and firmware updates.
For engineers reviewing the SST26VF064BAT-104I/MF datasheet, SST26VF064BAT-104I/MF pinout, SST26VF064BAT-104I/MF application, or SST26VF064BAT-104I/MF equivalent, key selection criteria include quad-I/O throughput, flexible block protection granularity, hardware write-protection pin behavior, and industrial temperature support (-40°C to +85°C) with AEC-Q100 Grade 2 qualification.
Technical Context
This device implements Microchip's proprietary SuperFlash® technology with split-gate cells and thick-oxide tunneling, enabling lower programming current and faster erase times than conventional NOR Flash. Its dual-mode interface supports legacy SPI (Mode 0/3) and high-throughput SQI with four multiplexed I/Os (SIO[3:0]), delivering up to 4× bandwidth over standard SPI at identical clock frequency.
The SST26VF064BAT-104I/MF integrates a 144-bit Block Protection Register (BPR), volatile Write Protection Lock-Down (WPLD), and nonvolatile Write Lock Lock-Down (nVWLDR) for permanent block protection. Its Configuration register (IOC bit) determines default I/O configuration: SST26VF064BA variants ship with IOC=1, enabling SIO2/SIO3 and disabling WP#/HOLD# at power-up - matching the /AT-104I/MF suffix.

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 W25Q64JWIM (64 Mbit, 133 MHz) | Higher max clock (133 MHz), no built-in Security ID, JEDEC JESD216-compliant SFDP table only - lacks OTP 2-Kbyte Sec ID and nVWLDR permanent lock-down. | Preferred for cost-sensitive consumer IoT where cryptographic identity is handled externally; not suitable for automotive security-critical boot. | Select W25Q64JWIM only if SQI bandwidth >104 MHz is required and Security ID is unnecessary; verify external authentication scheme compatibility. |
| Cypress S25FL164K0 (64 Mbit, 80 MHz) | Lower max frequency (80 MHz), supports HyperBus interface (not SQI), includes 256-byte OTP array - lacks quad-I/O burst modes and 104 MHz performance tier. | Better suited for legacy HyperBus-based SoCs (e.g., older Xilinx Zynq); incompatible with SST26VF064BAT-104I/MF's SQI command set and pin mapping. | Choose S25FL164K0 only when migrating from existing HyperBus designs; avoid for new SQI-based architectures due to protocol and timing mismatch. |
Compared with Winbond W25Q64JWIM and Cypress S25FL164K0, the SST26VF064BAT-104I/MF uniquely combines 104 MHz SQI throughput, factory-programmed Security ID, and nonvolatile write-lock lock-down - making it the only option among the three qualified for AEC-Q100 Grade 2 automotive boot memory with hardware-enforced firmware integrity.

FAQ
What is the default I/O configuration of SST26VF064BAT-104I/MF at power-up?
The SST26VF064BAT-104I/MF is an SST26VF064BA variant, meaning its Configuration register defaults with IOC=1 at power-up. This disables WP# and HOLD# pins and enables SIO2 and SIO3 for Quad I/O operation. The device boots into SPI-compatible mode but requires explicit EQIO command to activate full SQI functionality. This configuration is confirmed in DS20005119K Section 4.5.8 and Table 4-3 Note 1.
Does SST26VF064BAT-104I/MF support both SPI Mode 0 and Mode 3?
Yes, SST26VF064BAT-104I/MF supports both SPI Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1) as stated in DS20005119K page 6. In both modes, SIO[3:0] are sampled on the rising edge of SCK for input and driven after the falling edge for output. The distinction lies only in SCK idle state: low for Mode 0, high for Mode 3 - enabling interoperability with diverse host controllers without hardware modification.
How does the Security ID feature work in SST26VF064BAT-104I/MF?
The SST26VF064BAT-104I/MF includes a 2-Kbyte Security ID (Sec ID) space: 64 bits factory-programmed with a unique identifier (read-only, unchangeable) and the remainder user-programmable. Users issue PSID (Program Security ID) to write the user segment and LSID (Lockout Security ID) to permanently disable further writes. Once locked, the SEC bit in STATUS register becomes '1' and remains so indefinitely - providing immutable device identity for secure boot and anti-counterfeiting in automotive and industrial deployments.
What is the maximum burst read length supported by SST26VF064BAT-104I/MF?
SST26VF064BAT-104I/MF supports continuous linear burst reads and fixed-length bursts of 8, 16, 32, or 64 bytes with wrap-around, as specified in DS20005119K page 1. Burst modes operate in both SPI and SQI protocols. The RBSPI (ECH) and RBSQI (0CH) instructions enable wrap-around burst reads, allowing efficient streaming of firmware images or sensor data buffers without address retransmission overhead.
Is SST26VF064BAT-104I/MF pin-compatible with SST26VF064B variants?
No, SST26VF064BAT-104I/MF is not pin-compatible with SST26VF064B variants due to differing default I/O configurations. While both share identical pinouts (e.g., 8-contact WDFN), SST26VF064B powers up with IOC=0 (enabling WP# and HOLD#), whereas SST26VF064BAT-104I/MF powers up with IOC=1 (enabling SIO2/SIO3). Interchanging them without firmware reconfiguration causes WP#/HOLD# signals to be ignored or misinterpreted - potentially compromising write protection and hold functionality.
