Product details
Overview
SST25VF064C-80-4I-Q2AE from Microchip Technology (formerly Silicon Storage Technology) is a 64 Mbit SPI serial flash memory IC with dual I/O capability, operating at 2.7–3.6 V, supporting 80 MHz high-speed read, 4 KByte uniform sectors, and OTP Security ID. It serves as nonvolatile program/data storage in embedded microcontroller boot loaders and firmware update systems.
For engineers reviewing the SST25VF064C-80-4I-Q2AE datasheet, SST25VF064C-80-4I-Q2AE pinout, SST25VF064C-80-4I-Q2AE application, or SST25VF064C-80-4I-Q2AE equivalent, key selection criteria include SPI Mode 0/3 compatibility, dual-output/dual-I/O timing support, industrial temperature range (−40°C to +85°C), WSON-8 package footprint, and block-protection register configuration.
Technical Context
The SST25VF064C-80-4I-Q2AE implements a four-wire SPI interface with dedicated SI/SIO0 and SO/SIO1 pins enabling dual-output and dual-I/O modes. Its SuperFlash technology uses split-gate cells and thick-oxide tunneling for enhanced endurance (100,000 cycles) and data retention (>100 years).
It supports three fast read variants: 80 MHz single-bit (0BH), 75 MHz dual-output (3BH), and 50 MHz dual-I/O (BBH), each requiring distinct dummy cycles and pin usage. The device integrates a software status register with BUSY/WEL/BP/BPL bits and hardware write protection via WP# and RST#/HOLD# pins.

FAQ
What is the maximum clock frequency supported by SST25VF064C-80-4I-Q2AE for high-speed read operations?
The SST25VF064C-80-4I-Q2AE supports up to 80 MHz for High-Speed Read using the 0BH instruction. This is its highest-rated read speed and is validated under industrial temperature conditions (−40°C to +85°C) with 2.7–3.6 V supply. Other modes include 75 MHz for Fast-Read Dual-Output (3BH) and 50 MHz for Fast-Read Dual I/O (BBH). The "80" in the part number explicitly denotes this 80 MHz capability.
Does SST25VF064C-80-4I-Q2AE support both SPI Mode 0 and Mode 3?
Yes, SST25VF064C-80-4I-Q2AE is fully compatible with both SPI Mode 0 (CPOL = 0, CPHA = 0) and Mode 3 (CPOL = 1, CPHA = 1). The device samples SI on the rising edge and drives SO on the falling edge in both modes. This dual-mode support allows seamless integration with diverse microcontrollers without requiring hardware reconfiguration or level-shifting circuitry.
What package type is used for SST25VF064C-80-4I-Q2AE?
SST25VF064C-80-4I-Q2AE uses an 8-contact WSON package measuring 6 mm × 8 mm. This surface-mount, leadless package offers high thermal performance and compact board footprint - ideal for space-constrained applications like automotive modules and portable medical devices. It is RoHS-compliant and rated for moisture sensitivity level 3.
How does the Security ID feature work in SST25VF064C-80-4I-Q2AE?
The SST25VF064C-80-4I-Q2AE includes a 256-bit Security ID: 64 bits are factory-programmed with a unique identifier that cannot be altered, and 192 bits are user-programmable. Once programmed, the entire ID can be locked permanently using the Lockout SID command. The factory portion remains readable at all times and provides hardware-rooted identity for secure boot and anti-counterfeiting schemes.
Is SST25VF064C-80-4I-Q2AE still in active production?
No - SST25VF064C-80-4I-Q2AE is an obsolete (EOL) device per Microchip's official documentation (DS20005036C, April 2015).
