Product details
Overview
SST26VF032BT-104V/SM70SVAO from Microchip Technology is a 32-Mbit Serial Quad I/O™ (SQI™) Flash memory IC supporting dual-voltage operation (2.3V–3.6V or 2.7V–3.6V), 104 MHz max clock frequency at 2.7V–3.6V, and uniform 4-Kbyte sector erase architecture. It serves as nonvolatile program/data storage in microcontroller boot loaders, FPGA configuration, and industrial HMI firmware.
For engineers reviewing the SST26VF032BT-104V/SM70SVAO datasheet, SST26VF032BT-104V/SM70SVAO pinout, SST26VF032BT-104V/SM70SVAO application, or SST26VF032BT-104V/SM70SVAO equivalent, key selection considerations include SQI vs. SPI mode initialization (IOC bit default), hardware write-protection behavior (WP# pin enabled by default), and 8-lead SOIJ package compatibility with legacy PCB footprints.
Technical Context
This device implements a six-wire, 4-bit multiplexed I/O interface (SIO[3:0]) enabling quad-speed data transfer while maintaining full command-set compatibility with standard SPI protocols (Mode 0/3). Its SuperFlash® split-gate cell technology delivers 100,000 program/erase cycles and >100 years data retention.
Power-up defaults are factory-configured: IOC = 0 (enabling WP# and HOLD# pins, disabling SIO2/SIO3), WPEN = 0 (disabling hardware write protection), and BPNV = 1 (no permanent block lock-down). Configuration register bits control I/O mode switching, volatile/nonvolatile protection lock-down, and burst length selection.

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 W25Q32JVSIQ | 32 Mbit SPI-only (no SQI); 133 MHz max; 4-Kbyte sectors; no nVWLDR or Security ID | Lacks quad I/O speed boost and hardware-level security features; requires external encryption for secure boot | Select when cost sensitivity outweighs SQI performance and built-in security needs |
| Cypress S25FL132K0XMFI010 | 32 Mbit dual/quad SPI; 108 MHz max; 4-Kbyte sectors; no OTP Security ID or nVWLDR | Supports QPI mode but lacks factory-programmed unique ID and one-time programmable lock-down | Choose for migration from legacy Spansion designs where SQI is unnecessary but QPI compatibility is required |
Compared with SST26VF032BT-104V/SM70SVAO, W25Q32JVSIQ offers higher clock speed but sacrifices SQI bandwidth and security IP; S25FL132K0XMFI010 provides QPI compatibility but omits the 64-bit factory OTP ID and nonvolatile block lock-down - making SST26VF032BT-104V/SM70SVAO uniquely suited for secure, high-throughput embedded boot storage.

FAQ
What is the default I/O configuration mode for SST26VF032BT-104V/SM70SVAO at power-up?
The SST26VF032BT-104V/SM70SVAO powers up with IOC = 0 in the Configuration register, enabling WP# and HOLD# pins while disabling SIO2 and SIO3. This configures the device for standard SPI operation (x1/x2) by default. To enable SQI mode, the host must first set IOC = 1 via the Write Configuration Register command before issuing SQI-specific instructions like SQOR or SQIOR.
Does SST26VF032BT-104V/SM70SVAO support both 2.3V–3.6V and 2.7V–3.6V supply ranges simultaneously?
Yes, SST26VF032BT-104V/SM70SVAO supports single-supply operation across either 2.3V–3.6V or 2.7V–3.6V ranges. The 2.3V lower limit enables compatibility with newer ultra-low-power SoCs, while the 2.7V option ensures robust noise margin in electrically noisy industrial environments. Both ranges deliver full 104 MHz operation above 2.7V, with 80 MHz maximum below 2.7V.
How does the nonvolatile Write Lock Lock-Down register (nVWLDR) function in SST26VF032BT-104V/SM70SVAO?
The nVWLDR in SST26VF032BT-104V/SM70SVAO is a 72-bit one-time programmable register that permanently disables future changes to corresponding block protection bits. Writing '1' to any nVWLDR bit locks its associated memory block against all subsequent program/erase operations - even after power cycles. Once set, the bit cannot be cleared, providing irreversible hardware-enforced firmware partitioning critical for ASIL-B automotive applications.
Can SST26VF032BT-104V/SM70SVAO be used in AEC-Q100 Grade 2 automotive applications?
Yes, SST26VF032BT-104V/SM70SVAO is qualified for AEC-Q100 Grade 2 (−40°C to +105°C), making it suitable for engine control modules, ADAS domain controllers, and telematics units. Its SuperFlash® technology, 100,000-cycle endurance, and >100-year data retention meet stringent automotive reliability requirements. The 8-lead SOIJ package also supports standard automotive reflow profiles and board-level vibration resistance.
What is the purpose of the Security ID feature in SST26VF032BT-104V/SM70SVAO?
The Security ID in SST26VF032BT-104V/SM70SVAO provides a 2-Kbyte space containing a factory-programmed 64-bit unique identifier and a user-programmable area. This enables secure device authentication, anti-cloning, and firmware binding. The LSID command permanently locks the entire Security ID space, preventing further writes - ensuring cryptographic keys or device certificates remain tamper-proof throughout the product lifecycle.
