Product details

Overview

SST25VF064C-80-4C-Q2AE-T from Microchip Technology (formerly Silicon Storage Technology) is a 64 Mbit SPI serial flash memory IC with dual I/O capability, designed for embedded firmware storage and code execution in resource-constrained systems. It operates at 2.7–3.6 V, supports 80 MHz high-speed read (0BH), features 100,000 program/erase cycles, and delivers 12 mA active current at 80 MHz - enabling fast boot and reliable firmware updates in industrial controllers and IoT edge nodes.

For engineers reviewing the SST25VF064C-80-4C-Q2AE-T datasheet, SST25VF064C-80-4C-Q2AE-T pinout, SST25VF064C-80-4C-Q2AE-T application, or SST25VF064C-80-4C-Q2AE-T equivalent, this page provides verified pin functions, dual-I/O timing behavior, sector/block erase granularity, Security ID programmability, and real-world design implications of its SuperFlash technology - all aligned to the official DS20005036C EOL datasheet.

Technical Context

The SST25VF064C-80-4C-Q2AE-T implements a four-wire SPI interface compatible with Mode 0 and Mode 3, using SCK, SI/SIO0, SO/SIO1, CE#, WP#, and RST#/HOLD# pins. Its split-gate SuperFlash cell architecture enables faster erase (18 ms sector-erase, 35 ms chip-erase) and lower total energy per operation versus conventional NOR flash.

It supports three dual-mode read instructions: Fast-Read Dual-Output (3BH, 75 MHz), Fast-Read Dual I/O (BBH, 50 MHz), and High-Speed Read (0BH, 80 MHz), each with distinct dummy-cycle requirements and data routing across SIO0/SIO1. The device uses a 24-bit address space (000000H–7FFFFFH) organized into uniform 4 KByte sectors, 32 KByte blocks, and 64 KByte blocks.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	64 Mbit (8 MByte); supports full firmware image storage for mid-tier microcontrollers without external memory expansion.
Interface	SPI-compatible 4-wire bus (SCK, SI/SIO0, SO/SIO1, CE#); eliminates parallel bus routing and reduces PCB layer count.
Max Read Speed	80 MHz (High-Speed Read, 0BH instruction); enables sub-100 µs access to critical boot code sections.
Erase Granularity	Uniform 4 KByte sectors, 32 KByte blocks, 64 KByte blocks; allows fine-grained OTA update partitioning without full chip erase.
Endurance & Retention	100,000 program/erase cycles, >100 years data retention; validated for long-life industrial deployments with frequent field updates.
Security ID	256-bit OTP Security ID (64-bit factory-unique + 192-bit user-programmable); enables secure device authentication and anti-cloning.
Operating Voltage	2.7–3.6 V single supply; interoperable with 3.3 V logic families and simplifies power rail design.
Temperature Range	Industrial grade: –40°C to +85°C; qualified for use in automotive body control modules and factory automation PLCs.

Pinout & Package

Package: 8-contact WSON (6 mm × 8 mm), RoHS-compliant, moisture-sensitive level 3. Pin assignments are identical across 8-lead SOIC (200 mil), 16-lead SOIC (300 mil), and 8-WSON packages per DS20005036C Figure 2.

Pin/Terminal	Circuit Role	Design Meaning
CE#	Chip Enable	Active-low selection signal; must remain low throughout command sequence; deasserting terminates ongoing operations.
SCK	Serial Clock	Timing reference for SPI transfers; rising edge latches input (SI/SIO0), falling edge outputs data (SO/SIO1).
SI/SIO0	Serial Data Input / Dual I/O	Primary input path for commands/addresses/data; in Dual I/O mode, carries even-address bits and even-data bits.
SO/SIO1	Serial Data Output / Dual I/O	Primary output path for read data; in Dual I/O mode, carries odd-address bits and odd-data bits.
WP#	Write Protect	Hardware enable for Block-Protection-Lock (BPL); when low, prevents modification of BP3–BP0 unless BPL = 0.
RST#/HOLD#	Reset / Hold Function	Default reset pin at power-up; configurable as HOLD# via EHLD instruction to pause SPI transfers without clock reset.
VDD	Power Supply	2.7–3.6 V supply; powers internal charge pumps for erase/program; decoupling capacitor required per layout guidelines.
VSS	Ground	Reference return path; must be low-impedance and tied to system ground plane to minimize noise on SPI signals.

Key Features

Feature	Design Value
Dual I/O Read Modes	Supports BBH (50 MHz dual-input address + dual-output data) and 3BH (75 MHz dual-output only), cutting read latency by up to 2× vs standard SPI reads.
SuperFlash Technology	Split-gate cell with thick-oxide tunneling injector enables 18 ms sector erase (vs ~100 ms typical) and 1.5 ms page-program - reducing update time and system downtime.
Flexible Block Protection	Software-configurable BP3–BP0 bits protect memory regions from accidental overwrite; BPL bit locks protection settings permanently when WP# is asserted.
Security ID Space	Factory-programmed 64-bit unique ID + 192-bit user-programmable OTP area; supports secure boot key binding and device identity attestation.
Low-Power Standby	5 µA typical standby current enables battery-backed operation in always-on sensors and metering applications.
End-of-Write Detection	BUSY bit polling in status register (bit 0) replaces fixed-timing delays - simplifies firmware integration and improves reliability across voltage/temperature corners.

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, 104 MHz Quad SPI, 4-byte addressing, no dual-I/O-only modes; requires QSPI controller support.	Higher throughput in QSPI mode but incompatible with legacy dual-I/O-only host drivers.	Select if host MCU supports Quad SPI and bandwidth >80 MB/s is required; not drop-in for SST25VF064C-80-4C-Q2AE-T's dual-I/O timing.
Macronix MX25L6433FZNI-10G	64 Mbit, 104 MHz standard SPI, no dual-I/O instructions; supports standard 03H/0BH reads only.	Lacks dual-output/dual-I/O acceleration - read latency ~2× higher than SST25VF064C-80-4C-Q2AE-T at same clock rate.	Choose for cost-sensitive designs where dual-I/O performance is unnecessary and legacy SPI-only firmware exists.

Compared with W25Q64JVSSIQ and MX25L6433FZNI-10G, the SST25VF064C-80-4C-Q2AE-T uniquely balances 80 MHz single-I/O speed with dual-I/O acceleration (75/50 MHz), making it optimal for hosts lacking Quad SPI but requiring faster-than-standard read performance - especially in firmware hot-path access and OTA staging.

FAQ

What does the "-80-4C-Q2AE-T" suffix indicate for SST25VF064C-80-4C-Q2AE-T?

The "-80" denotes 80 MHz maximum High-Speed Read frequency (0BH instruction), "-4C" specifies commercial temperature range (0°C to +70°C), "-Q2AE" identifies the 8-contact WSON (6 mm × 8 mm) package with exposed pad, and "-T" indicates tape-and-reel packaging. Note: This specific suffix variant is rated for commercial temp - the industrial-grade version is SST25VF064C-80-4I-Q2AE-T.

Does SST25VF064C-80-4C-Q2AE-T support Quad SPI mode?

No. SST25VF064C-80-4C-Q2AE-T supports only standard SPI (Mode 0/3) and dual-I/O modes (Fast-Read Dual-Output and Fast-Read Dual I/O). It lacks quad data lines (IO2/IO3) and corresponding instructions (e.g., 6BH, EBH), unlike Quad SPI flash devices such as Winbond W25Q64JV.

How is the Security ID programmed and locked on SST25VF064C-80-4C-Q2AE-T?

The SST25VF064C-80-4C-Q2AE-T Security ID is programmed using the Program SID instruction (A5H) after issuing Write-Enable (WREN), then locked permanently via Lockout SID (85H). The 64-bit factory ID is immutable; only the 192-bit user segment is writable. Once locked, no further writes to any part of the Security ID are possible.

What happens if CE# is deasserted mid-read on SST25VF064C-80-4C-Q2AE-T?

Deasserting CE# (driving high) during any read instruction (03H, 0BH, 3BH, BBH) immediately terminates the transfer and places SO/SIO1 in high-impedance state. The internal address pointer retains its last value, so subsequent reads resume from that address - enabling partial reads and streaming control without address reinitialization.

Can SST25VF064C-80-4C-Q2AE-T be used in place of SST25VF064C-80-4I-Q2AE-T?

Only in commercial-temperature environments (0°C to +70°C). The SST25VF064C-80-4C-Q2AE-T is not qualified for –40°C to +85°C operation. Substituting it in industrial applications risks parametric failure during cold startup or thermal stress, particularly in erase/write timing margins and data retention.
