Product details

Overview

SST25VF064C-80-4I-Q2AE-T from Microchip Technology is a 64 Mbit SPI serial flash memory IC with dual I/O capability, operating at 2.7–3.6 V and supporting up to 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, 256-byte page programming, and industrial temperature range (−40°C to +85°C). It is used in embedded firmware storage for microcontrollers in industrial control systems.

For engineers reviewing the SST25VF064C-80-4I-Q2AE-T datasheet, SST25VF064C-80-4I-Q2AE-T pinout, SST25VF064C-80-4I-Q2AE-T application, or SST25VF064C-80-4I-Q2AE-T equivalent, key selection criteria include SPI mode 0/3 compatibility, dual I/O timing margins, sector/block erase granularity, Security ID programmability, and industrial-grade reliability metrics (100K endurance, >100-year data retention).

Technical Context

The SST25VF064C-80-4I-Q2AE-T implements a four-wire SPI interface with dedicated SI/SO pins and dual-capable SIO0/SIO1 terminals, enabling single-bit, dual-output, and dual I/O instruction modes. Its SuperFlash technology uses split-gate cells and thick-oxide tunneling for reduced program/erase energy versus conventional flash.

It supports hardware write protection via WP# and software block protection via BP3–BP0 bits in the status register, with BPL bit lock-down enabled when WP# is low. The RST#/HOLD# pin functions as reset by default and can be reconfigured to hold mode via EHLD instruction without power cycle interruption.

Pinout & Package

Package: 8-contact WSON (6 mm × 8 mm), RoHS-compliant, moisture-sensitive level 3.

Pin/Terminal	Circuit Role	Design Meaning
CE#	Chip Enable	Active-low device select; must remain low throughout command sequence to prevent premature termination.
SCK	Serial Clock	Timing reference for all SPI transfers; supports Mode 0 (SCK idle low) and Mode 3 (SCK idle high).
SI/SIO0	Serial Input / Dual I/O 0	Primary input path for commands/addresses/data; becomes bidirectional in dual I/O mode for address/data input.
SO/SIO1	Serial Output / Dual I/O 1	Primary output path for read data; becomes bidirectional in dual I/O mode for parallel address/data input.
WP#	Write Protect	Enables BPL bit lock-down; when pulled low, prevents modification of BP3–BP0 unless BPL = 0.
RST#/HOLD#	Reset / Hold Control	Hardware reset by default; configurable to HOLD# via EHLD instruction to pause SPI without clock reset.
VDD	Power Supply	2.7–3.6 V supply; powers internal charge pumps for erase/program operations.
VSS	Ground	Reference for all I/O and internal circuitry; requires low-impedance connection to minimize noise coupling.

Key Features

Equivalent & Alternatives

The following parts are listed as comparable options for similar SPI serial flash memory applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Winbond W25Q64JVSSIQ	64 Mbit, 133 MHz max read, Quad SPI support (QPI), no dual I/O mode; 8-lead SOIC only.	Lacks dual I/O but adds quad mode for higher bandwidth; no Security ID feature.	Choose for designs needing QPI protocol or higher clock speed, where dual I/O is not required and security ID is optional.
Macronix MX25L6433FZNI-10G	64 Mbit, 104 MHz max read, supports dual/quad I/O, includes 64-bit UID but no user-programmable Security ID segment.	Offers faster read and quad mode, but lacks 192-bit user-programmable ID space for custom key injection.	Prefer when maximum read throughput is critical and factory UID suffices for device identity; avoid if user-programmable secure ID is mandatory.

Compared with SST25VF064C-80-4I-Q2AE-T, W25Q64JVSSIQ trades dual I/O for quad SPI and higher speed but omits Security ID programmability, while MX25L6433FZNI-10G adds quad mode and faster timing but lacks user-writable security space - making SST25VF064C-80-4I-Q2AE-T uniquely suited for secure, dual-I/O–optimized industrial firmware storage.

FAQ

What is the maximum clock frequency supported by SST25VF064C-80-4I-Q2AE-T in high-speed read mode?

The SST25VF064C-80-4I-Q2AE-T supports up to 80 MHz in high-speed read mode using the 0BH instruction. This timing is validated under industrial temperature conditions (−40°C to +85°C) and 2.7–3.6 V supply, delivering effective throughput of ~80 MB/s for sequential reads. The "80" in the part number explicitly denotes this 80 MHz rating.

Does SST25VF064C-80-4I-Q2AE-T support both SPI Mode 0 and Mode 3?

Yes, SST25VF064C-80-4I-Q2AE-T 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, with SCK idle state differing per mode - enabling interoperability with diverse host controllers without hardware adaptation.

How is the Security ID implemented in SST25VF064C-80-4I-Q2AE-T?

The SST25VF064C-80-4I-Q2AE-T provides a 256-bit Security ID: 64 bits factory-programmed with a unique identifier (non-erasable, non-modifiable) and 192 bits user-programmable. Programming uses the Program SID (A5H) command, and locking uses Lockout SID (85H); once locked, the SEC bit in the status register becomes permanent '1', preventing further writes to the entire Security ID space.

What package type does SST25VF064C-80-4I-Q2AE-T use?

SST25VF064C-80-4I-Q2AE-T uses an 8-contact WSON package measuring 6 mm × 8 mm, with exposed pad for thermal dissipation. This compact, surface-mount package supports automated assembly and meets IPC/JEDEC J-STD-020 moisture sensitivity level 3 requirements - ideal for space-constrained industrial PCBs.

Can SST25VF064C-80-4I-Q2AE-T be used in place of standard SPI flash without modifying firmware?

Yes, SST25VF064C-80-4I-Q2AE-T is backward-compatible with standard SPI flash protocols: it responds to legacy Read (03H), Write Enable (06H), Page Program (02H), and Sector Erase (20H) instructions. Dual I/O and Security ID features are opt-in via new opcodes (BBH, A5H, 85H), so existing firmware continues to operate unchanged unless leveraging advanced functionality.
