Product details
Overview
SST25VF064C-80-4I-SCE-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, supporting up to 80 MHz high-speed read (0BH), and featuring uniform 4 KByte sectors for embedded firmware storage in microcontroller-based systems.
For engineers reviewing the SST25VF064C-80-4I-SCE-T datasheet, SST25VF064C-80-4I-SCE-T pinout, SST25VF064C-80-4I-SCE-T application, or SST25VF064C-80-4I-SCE-T equivalent, this page delivers verified electrical parameters, SPI mode compatibility (0 and 3), dual-input page-program timing, security ID architecture, and industrial temperature support (–40°C to +85°C).
Technical Context
The SST25VF064C-80-4I-SCE-T implements SST's proprietary SuperFlash technology with split-gate cells and thick-oxide tunneling injectors, enabling 100,000 program/erase cycles and >100-year data retention. It uses a four-wire SPI interface (SCK, SI/SIO0, SO/SIO1, CE#) with hardware reset/hold on RST#/HOLD# and write protection via WP# and status register BP bits.
It supports three read modes: standard Read (03H, 33 MHz), High-Speed Read (0BH, 80 MHz with dummy byte), and dual-output Fast-Read (3BH, 75 MHz) or dual I/O Fast-Read (BBH, 50 MHz), all with automatic address wraparound and continuous streaming until CE# deassertion.
Key Specifications

Pinout & Package
Package: 8-lead SOIC (200 mils), RoHS-compliant, surface-mountable with 1.27 mm pitch.
| 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 SPI transfers; rising edge latches input, falling edge outputs data (Mode 0/3 compatible) |
| SI/SIO0 | Serial Input / Dual I/O Lane 0 | Carries commands, addresses, and even data bits (D6,D4,D2,D0) in dual I/O mode; bidirectional in BBH/3BH |
| SO/SIO1 | Serial Output / Dual I/O Lane 1 | Outputs data or odd bits (D7,D5,D3,D1) in dual mode; high-impedance when HOLD# active |
| WP# | Write Protect | Enables lock-down of Block-Protection bits (BP3–BP0) via BPL bit when driven low |
| RST#/HOLD# | Reset or Hold Control | Default reset function at power-on; configurable as hold pin 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 return path; decoupling capacitor required within 10 mm of VDD/VSS pins |
Key Features
| Feature | Design Value |
|---|---|
| Dual I/O Read Support | Enables 50 MHz Fast-Read Dual I/O (BBH) and 75 MHz Fast-Read Dual-Output (3BH), doubling effective throughput vs. standard SPI |

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 SPI (QPI), 1.65–3.6 V supply, no dual-I/O mode; requires QSPI controller | Higher bandwidth but incompatible with legacy dual-I/O SPI host interfaces | Select only if migrating to QSPI-capable MCU and requiring >80 MHz throughput |
| Macronix MX25L6433FZNI-10G | 64 Mbit, 104 MHz standard SPI, 2.7–3.6 V, supports DTR mode but lacks Security ID and dual-input page-program | Lacks OTP Security ID and 50 MHz dual-input programming - unsuitable for secure boot or rapid OTA | Prefer for cost-sensitive consumer applications where security and fast writes are non-critical |
Compared with W25Q64JVSSIQ and MX25L6433FZNI-10G, the SST25VF064C-80-4I-SCE-T uniquely balances industrial-grade reliability, dual-I/O acceleration, and integrated security ID - making it optimal for safety-critical firmware storage where pin-compatible migration from legacy SPI hosts is required.

FAQ
What is the maximum clock frequency supported by SST25VF064C-80-4I-SCE-T for high-speed read operations?
The SST25VF064C-80-4I-SCE-T supports up to 80 MHz for High-Speed Read using instruction 0BH with a dummy byte. This is the highest guaranteed read speed specified in the official EOL datasheet DS20005036C. The '80' in the part number explicitly denotes this 80 MHz rating, validated across the full industrial temperature range (–40°C to +85°C) and 2.7–3.6 V supply.
Does SST25VF064C-80-4I-SCE-T support dual I/O programming, and what is its typical page-program time?
Yes, the SST25VF064C-80-4I-SCE-T supports Dual-Input Page-Program (instruction A2H) at up to 50 MHz, enabling faster data loading than standard single-input mode. Its typical page-program time is 1.5 ms per 256-byte page, as confirmed in the EOL datasheet DS20005036C section "Features" and "Page-Program" timing tables.
What package type is used for SST25VF064C-80-4I-SCE-T, and is it RoHS compliant?
The SST25VF064C-80-4I-SCE-T uses an 8-lead SOIC (200 mils) package, as explicitly stated in the "Packages Available" section of DS20005036C. All variants, including this one, are RoHS compliant - confirmed in the "Features" list and Microchip's official product change notices.
How does the Security ID feature work in SST25VF064C-80-4I-SCE-T, and can it be reprogrammed?
The SST25VF064C-80-4I-SCE-T includes a 256-bit Security ID: 64 bits factory-programmed (unique, immutable) and 192 bits user-programmable. Once programmed via instruction A5H and locked via instruction 85H, the entire Security ID becomes permanently read-only. No erase or reprogramming is possible after lockout - a hardware-enforced security guarantee documented in DS20005036C section "Security ID".
Is SST25VF064C-80-4I-SCE-T still in production, and what is its lifecycle status?
The SST25VF064C-80-4I-SCE-T is an obsolete (EOL) device, as indicated by the "EOL Data Sheet" title and footer in DS20005036C (dated 04/15). Microchip recommends contacting its sales team for replacement guidance. However, Aetrix Electronics maintains active inventory and supply-chain continuity support for this part to serve legacy design refreshes and long-lifecycle industrial programs.
