Product details
Overview
SST25VF064C-80-4I-S3AE from Microchip Technology is a 64 Mbit (8 MB) SPI serial flash memory IC with dual I/O capability, operating at 2.7–3.6 V, supporting 80 MHz high-speed read (0BH), 75 MHz fast-read dual-output (3BH), and 50 MHz fast-read dual I/O (BBH). It features uniform 4 KByte sectors, 32/64 KByte overlay blocks, and 256-byte page programming - used for firmware storage in embedded microcontrollers, boot code in industrial controllers, and configuration data in networking equipment.
For engineers reviewing the SST25VF064C-80-4I-S3AE datasheet, SST25VF064C-80-4I-S3AE pinout, SST25VF064C-80-4I-S3AE application, or SST25VF064C-80-4I-S3AE equivalent, key selection considerations include its 8-lead SOIC (200 mil) package, SPI Mode 0/3 compatibility, dual I/O timing support, 100,000-cycle endurance, and factory-programmed 64-bit unique Security ID.
Technical Context
The SST25VF064C-80-4I-S3AE implements a four-wire SPI interface with CE#, SCK, SI/SIO0, and SO/SIO1 pins, enabling both single- and dual-I/O read/write operations. Its SuperFlash technology uses split-gate cells and thick-oxide tunneling to achieve superior reliability over conventional NOR flash.
It supports hardware write protection via WP# and software block protection via BP3–BP0 bits in the status register, with configurable protection levels from upper 1/128 to full array. The RST#/HOLD# pin operates as reset by default and can be reconfigured to hold mode via EHLD instruction without power cycle.

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 W25Q64JVSSIQ | 64 Mbit, 133 MHz quad I/O, 1.65–3.6 V supply, 4 KByte sectors, no factory-unique ID | Supports QPI and DTR modes for higher bandwidth; lacks OTP Security ID and industrial temp option | Choose for higher-speed designs needing quad I/O or lower voltage operation; avoid if device authentication or extended temperature is required |
| Macronix MX25L6433FZNI-10G | 64 Mbit, 104 MHz quad I/O, 2.7–3.6 V, 4 KByte sectors, 64-bit unique ID (not OTP), industrial temp | Includes unique ID but not one-time programmable; supports continuous read mode and deep power-down | Prefer when deep power-down current (<1 µA) or continuous read simplification is needed; verify ID usage model aligns with security requirements |
Compared with SST25VF064C-80-4I-S3AE, W25Q64JVSSIQ offers higher bandwidth via quad I/O but omits factory-unique OTP ID and industrial temp grade, while MX25L6433FZNI-10G adds deep power-down and continuous read but uses volatile unique ID - making SST25VF064C-80-4I-S3AE optimal where immutable device identity and guaranteed industrial reliability are mandatory.

FAQ
What is the operating voltage range for the SST25VF064C-80-4I-S3AE?
The SST25VF064C-80-4I-S3AE operates from 2.7 V to 3.6 V. This single-supply range eliminates need for level shifters in 3.3 V systems and ensures compatibility with common microcontroller I/O voltages. Operation outside this range may cause unreliable reads or failed program/erase cycles. The SST25VF064C-80-4I-S3AE datasheet specifies 12 mA typical active read current at 80 MHz within this voltage window.
Does the SST25VF064C-80-4I-S3AE support SPI Mode 0 and Mode 3?
Yes, the SST25VF064C-80-4I-S3AE supports both SPI Mode 0 (CPOL = 0, CPHA = 0) and Mode 3 (CPOL = 1, CPHA = 1). In Mode 0, SCK idles low and data is sampled on the rising edge; in Mode 3, SCK idles high with identical sampling timing. The SST25VF064C-80-4I-S3AE automatically adapts to either mode based on master configuration - no internal register setting required.
What is the purpose of the RST#/HOLD# pin on the SST25VF064C-80-4I-S3AE?
The RST#/HOLD# pin on the SST25VF064C-80-4I-S3AE serves dual functions: hardware reset (RST#) by default at power-up, and optional hold mode (HOLD#) enabled via EHLD instruction. As RST#, it forces the device into known state and clears BUSY/WEL bits. As HOLD#, it pauses ongoing SPI transfers without resetting clocks or losing address context. The SST25VF064C-80-4I-S3AE returns to RST# function only after power cycle.
How does the Security ID feature work in the SST25VF064C-80-4I-S3AE?
The SST25VF064C-80-4I-S3AE includes a 256-bit Security ID: 64 bits factory-programmed with a unique identifier (immutable), and 192 bits user-programmable. Programming requires WREN followed by Program SID (A5H); locking requires Lockout SID (85H), which sets SEC bit permanently. Once locked, no further writes are possible. The SST25VF064C-80-4I-S3AE supports Read SID (88H) for verification, and the factory ID remains readable even after lockout.
Can the SST25VF064C-80-4I-S3AE be used in industrial temperature applications?
Yes, the SST25VF064C-80-4I-S3AE is rated for industrial temperature range (–40°C to +85°C), as confirmed by its "I" suffix in the part number and explicit specification in the datasheet. This makes it suitable for deployment in harsh environments such as factory floors, outdoor telecom cabinets, and automotive under-hood modules. The SST25VF064C-80-4I-S3AE maintains full 100,000-cycle endurance and >100-year data retention across this range.
