Product details

Overview

SST25VF064C-80-4I-S3AE-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, 32/64 KByte overlay blocks, and 256-byte page programming - deployed in embedded boot code storage, firmware update partitions, and configuration data retention for industrial controllers.

For engineers reviewing the SST25VF064C-80-4I-S3AE-T datasheet, SST25VF064C-80-4I-S3AE-T pinout, SST25VF064C-80-4I-S3AE-T application, or SST25VF064C-80-4I-S3AE-T 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), 100,000-cycle endurance, and WSON-8 (6 mm × 8 mm) package footprint with verified pin mapping.

Technical Context

The SST25VF064C-80-4I-S3AE-T implements a four-wire SPI interface with dedicated SI/SIO0 and SO/SIO1 pins enabling dual-output and dual-I/O modes, using SST's proprietary SuperFlash split-gate CMOS technology for enhanced reliability and reduced program/erase energy consumption. It supports hardware reset and hold functions via the RST#/HOLD# pin, with configurable behavior via EHLD instruction.

Its status register includes BUSY, WEL, BP3–BP0, SEC, and BPL bits for real-time operation monitoring and flexible software write protection across 16 protection levels - from no protection to full chip lock - while the Security ID provides 64-bit factory-unique and 192-bit user-programmable OTP space.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	64 Mbit (8 MByte), organized as uniform 4 KByte sectors, 32 KByte and 64 KByte overlay blocks - enables granular firmware partitioning and safe over-the-air updates.
Read Speed	80 MHz (High-Speed Read, 0BH), 75 MHz (Fast-Read Dual-Output, 3BH), 50 MHz (Fast-Read Dual I/O, BBH) - reduces boot latency and accelerates configuration loading.
Write Performance	Page-Program time: 1.5 ms (typical, 256 bytes); Sector/Block-Erase: 18 ms (typical); Chip-Erase: 35 ms (typical) - minimizes field update downtime.
Endurance & Retention	100,000 program/erase cycles (typical); >100 years data retention - suitable for long-life industrial deployments without refresh cycles.
Supply & Power	2.7–3.6 V single supply; active read current: 12 mA @ 80 MHz (single-bit), 14 mA @ 75 MHz (dual-bit); standby current: 5 µA (typical) - compatible with low-power MCU host systems.
Temperature Range	Industrial grade: −40°C to +85°C - validated for operation in motor drives, PLCs, and outdoor edge nodes.
Security Features	One-Time Programmable 256-bit Security ID (64-bit factory-unique + 192-bit user-programmable); Lockout SID command prevents reprogramming - supports device authentication and secure firmware binding.

Pinout & Package

Package: 8-contact WSON (6 mm × 8 mm), RoHS-compliant, moisture-sensitive level 3 - optimized for compact PCB layouts and automated SMT assembly.

Pin/Terminal	Circuit Role	Design Meaning
CE#	Chip Enable	Active-low selection signal; must remain low during full instruction sequence - controls SPI transaction boundaries and enables multi-device bus sharing.
SIO0 / SI	Serial Data Input / Dual I/O 0	Primary input for commands, addresses, and data; functions as bidirectional I/O in Dual I/O mode - supports 2-bit-per-clock addressing in BBH instruction.
SIO1 / SO	Serial Data Output / Dual I/O 1	Primary output for read data; functions as bidirectional I/O in Dual I/O mode - delivers odd/even data bits simultaneously in 3BH/BBH reads.
SCK	Serial Clock	Master-generated clock; rising edge latches inputs, falling edge shifts out outputs - supports both SPI Mode 0 (SCK idle low) and Mode 3 (SCK idle high).
WP#	Write Protect	Hardware enable for Block-Protection-Lock (BPL) bit - when low, locks BP3–BP0 bits to prevent accidental firmware overwrite.
RST#/HOLD#	Reset / Hold Control	Configurable pin: defaults to hardware reset (RST#); enabled as HOLD# via EHLD instruction - pauses ongoing SPI transfers without resetting internal state.
VDD	Power Supply	2.7–3.6 V core supply - powers logic and memory array; requires local 0.1 µF decoupling per datasheet layout guidelines.
VSS	Ground	Reference return path for all signals and power - must be connected to low-impedance system ground plane.

Key Features

Feature	Design Value
Dual I/O Interface Support	Enables BBH Fast-Read Dual I/O (50 MHz) with 2-bit address/data transfer per clock - cuts instruction latency by ~50% vs standard SPI read.
SuperFlash Technology	Split-gate cell + thick-oxide tunneling injector achieves lower program current and faster erase than conventional flash - reduces total energy per erase/program cycle.
Flexible Block Protection	16 software-configurable protection levels (BP3–BP0) covering ranges from upper 1/128 to full chip - allows selective locking of bootloader, app, and config regions.
Security ID with Lockout	Factory-unique 64-bit ID + 192-bit user space, programmable via A5H, lockable via 85H - prevents cloning and enables cryptographic binding in secure boot flows.
Industrial Temperature Operation	Guaranteed functionality from −40°C to +85°C with full timing compliance - eliminates derating concerns in uncontrolled environments like factory floors or telecom cabinets.

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 W25Q64JVSIQ	64 Mbit, 104 MHz max read, Quad SPI support (QPI), no dual-I/O mode; 3.3 V only; 100,000 cycles, same industrial temp.	Lacks dual-I/O instruction set (BBH/3BH); supports faster QPI but requires different driver stack and pinout (4 I/O lines vs 2).	Select if system requires quad-mode throughput or existing Winbond QPI firmware infrastructure - not drop-in for SST25VF064C-80-4I-S3AE-T dual-I/O use cases.
Cypress S25FL164K0XMFI010	64 Mbit, 80 MHz read, supports dual/quad SPI, 1.8 V/3.3 V dual supply; 100,000 cycles, industrial temp; includes SFDP for auto-configuration.	Requires 1.8 V I/O support; SFDP simplifies initialization but adds complexity for legacy SPI-only hosts; pinout differs (SOIC-16 vs WSON-8).	Prefer for new designs needing voltage flexibility and standardized JEDEC SFDP discovery - not suitable for direct replacement due to supply and footprint mismatch.

Compared with W25Q64JVSIQ and S25FL164K0XMFI010, the SST25VF064C-80-4I-S3AE-T uniquely balances dual-I/O bandwidth efficiency, single 3.3 V supply simplicity, and WSON-8 space savings - making it optimal for cost- and size-constrained industrial MCU designs where dual-mode SPI optimization matters more than quad throughput or multi-voltage support.

FAQ

What is the operating voltage range for the SST25VF064C-80-4I-S3AE-T?

The SST25VF064C-80-4I-S3AE-T operates from 2.7 V to 3.6 V DC. This single-supply range ensures compatibility with common 3.3 V logic systems while allowing operation down to 2.7 V during brown-out conditions. The device maintains full timing specifications across this range, including 80 MHz high-speed read performance at minimum VDD.

Does the SST25VF064C-80-4I-S3AE-T support SPI Mode 0 and Mode 3?

Yes, the SST25VF064C-80-4I-S3AE-T explicitly supports both SPI Mode 0 (CPOL = 0, CPHA = 0) and Mode 3 (CPOL = 1, CPHA = 1). The SCK idle state differs between modes - low in Mode 0, high in Mode 3 - but SI sampling occurs on the rising edge and SO output on the falling edge in both, ensuring interoperability with diverse host controllers.

What package type is used for the SST25VF064C-80-4I-S3AE-T?

The SST25VF064C-80-4I-S3AE-T uses an 8-contact WSON package measuring 6 mm × 8 mm. This leadless, surface-mount package features exposed pad thermal enhancement and complies with RoHS and JEDEC moisture sensitivity level 3 (MSL3) requirements - confirmed in the official Microchip datasheet DS20005036C.

How does the Security ID feature work on the SST25VF064C-80-4I-S3AE-T?

The SST25VF064C-80-4I-S3AE-T includes a 256-bit Security ID: 64 bits factory-programmed with a unique identifier (read-only), and 192 bits user-programmable via the Program SID (A5H) command. Once locked with Lockout SID (85H), the entire Security ID becomes permanently read-only - providing immutable device identity for secure boot and anti-cloning applications.

Is the SST25VF064C-80-4I-S3AE-T still in production or obsolete?

The SST25VF064C-80-4I-S3AE-T is marked End-of-Life (EOL) by Microchip, as indicated in the official EOL datasheet DS20005036C (April 2015). However, Aetrix Electronics maintains active inventory and supply chain continuity support for this part, including lifecycle coordination and last-time-buy planning for legacy industrial and medical programs.
