Product details
Overview
SST25VF064C-80-4I-SCE 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 and 64 KByte blocks for flexible erase. It is used in embedded firmware storage for industrial controllers requiring fast boot code retrieval and field-upgradable configuration data.
For engineers reviewing the SST25VF064C-80-4I-SCE datasheet, SST25VF064C-80-4I-SCE pinout, SST25VF064C-80-4I-SCE application, or SST25VF064C-80-4I-SCE equivalent, key selection criteria include SPI Mode 0/3 compatibility, dual-I/O timing support (BBH/3BH), 256-byte page programming, hardware write protection via WP#, and industrial temperature range (-40°C to +85°C) compliance.
Technical Context
The SST25VF064C-80-4I-SCE implements a four-wire SPI interface with configurable dual-input/output operation using SIO0/SIO1 pins, enabling simultaneous address/data transfer in Fast-Read Dual I/O mode (BBH) at 50 MHz. Its SuperFlash technology uses split-gate cells and thick-oxide tunneling for enhanced endurance (100,000 cycles) and >100-year data retention.
It supports three erase granularities - 4 KByte sectors, 32 KByte blocks, and 64 KByte blocks - with chip-erase time of 35 ms (typical). The device integrates a software status register with block-protection bits (BP3–BP0), BUSY/WEL flags, and Security ID lockout (64-bit factory-unique + 192-bit user-programmable).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mbit (8 MByte); enables storage of full bootloader + application firmware in single package. |
| Supply Voltage | 2.7–3.6 V; compatible with 3.3 V logic systems without level-shifting. |
| Max Read Speed | 80 MHz (0BH instruction); reduces boot latency in real-time embedded systems. |
| Erase Granularity | Uniform 4 KByte sectors / 64 KByte blocks; allows selective firmware update without full chip erase. |
| Endurance | 100,000 program/erase cycles (typical); supports frequent field updates in IoT edge nodes. |
| Data Retention | >100 years; ensures long-term reliability in unattended industrial deployments. |
| Page Size | 256 bytes; matches typical MCU cache line and minimizes partial-page write overhead. |
| Operating Temp | -40°C to +85°C (Industrial grade); qualified for use in motor drives and outdoor gateways. |
Pinout & Package
Package: 8-lead SOIC (200 mils), RoHS-compliant, surface-mountable with standard reflow profile.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CE# | Chip Enable | Active-low selection signal; must remain low during full instruction sequence including address and data phases. |
| SIO0 / SI | Serial Data Input / Dual I/O 0 | Primary input for commands/addresses; functions as bidirectional data line in Dual I/O modes (3BH/BBH). |
| SIO1 / SO | Serial Data Output / Dual I/O 1 | Primary output for read data; functions as bidirectional data line in Dual I/O modes, delivering odd/even bit pairs per clock. |
| SCK | Serial Clock | Edge-triggered timing reference; rising edge latches inputs, falling edge shifts out outputs (Mode 0/3 compatible). |
| WP# | Write Protect | Hardware-enables status register lock-down (BPL bit); prevents accidental modification of block protection settings. |
| RST#/HOLD# | Reset / Hold Control | Configurable pin: defaults to hardware reset (RST#); enabled as HOLD# via EHLD instruction to pause SPI without clock reset. |
| VDD | Power Supply | 2.7–3.6 V supply; decoupling capacitor required within 10 mm of pin for stable high-speed operation. |
| VSS | Ground | Reference return path; must be connected to low-impedance system ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Dual I/O Read Modes | Supports Fast-Read Dual-Output (3BH @ 75 MHz) and Fast-Read Dual I/O (BBH @ 50 MHz), doubling effective throughput vs. standard SPI read. |
| SuperFlash Technology | Split-gate cell architecture reduces program/erase current and time, cutting total energy per operation by ~40% vs. conventional flash. |
| Flexible Block Protection | Software-configurable BP3–BP0 bits protect memory regions from unintended writes; all blocks protected by default at power-up. |
| Security ID | 256-bit OTP space: 64-bit factory-unique ID + 192-bit user-programmable segment, locked permanently via Lockout SID command. |
| Industrial Temperature Range | Rated -40°C to +85°C; validated across thermal cycling and extended life testing for automotive body control modules. |

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, 3.3 V, 104 MHz Quad SPI (QPI) capable; no dual-I/O-only mode; requires QPI enable sequence. | Higher bandwidth in QPI mode but lacks native dual-I/O backward compatibility with legacy SST25VF064C-80-4I-SCE firmware drivers. | Select if migrating to quad-I/O architecture and redesigning SPI initialization; not drop-in for existing dual-I/O implementations. |
| Macronix MX25L6406EM2I-12G | 64 Mbit, 3 V, 80 MHz standard SPI; supports dual-I/O (3BH) but not Fast-Read Dual I/O (BBH); no Security ID feature. | Matches read speed and voltage but omits BBH instruction and 256-bit Security ID; lower security assurance for regulated medical/industrial use. | Choose for cost-sensitive designs where dual-I/O suffices and security ID is unnecessary; verify BP bit mapping compatibility. |
Compared with Winbond W25Q64JVSIQ and Macronix MX25L6406EM2I-12G, the SST25VF064C-80-4I-SCE uniquely combines BBH dual-I/O mode, factory-programmed Security ID, and SuperFlash low-energy erase-making it optimal for legacy-compatible, security-aware industrial firmware storage where minimal layout change and proven reliability are mandatory.

FAQ
What is the maximum clock frequency supported by SST25VF064C-80-4I-SCE for standard SPI read operations?
The SST25VF064C-80-4I-SCE supports up to 80 MHz for High-Speed Read (0BH instruction), 33 MHz for standard Read (03H), 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 the 80 MHz high-speed read capability, verified in the official Microchip datasheet DS20005036C.
Does SST25VF064C-80-4I-SCE support both SPI Mode 0 and Mode 3?
Yes, the SST25VF064C-80-4I-SCE is fully compatible with SPI Mode 0 (CPOL = 0, CPHA = 0) and Mode 3 (CPOL = 1, CPHA = 1), as confirmed in the "Device Operation" section of the datasheet. This dual-mode support ensures interoperability with diverse host controllers without requiring hardware modifications to the SST25VF064C-80-4I-SCE interface.
What is the purpose of the RST#/HOLD# pin on SST25VF064C-80-4I-SCE?
The RST#/HOLD# pin on SST25VF064C-80-4I-SCE serves two distinct functions: by default, it acts as a hardware reset (RST#) to initialize internal logic; after issuing the EHLD instruction, it becomes a hold pin (HOLD#) that pauses ongoing SPI transactions without resetting the clock sequence. This dual functionality is documented in the "Reset/Hold Mode" section of the SST25VF064C-80-4I-SCE datasheet.
How does the Security ID feature work in SST25VF064C-80-4I-SCE?
The SST25VF064C-80-4I-SCE includes a 256-bit Security ID: 64 bits are factory-programmed with a unique identifier and cannot be altered; the remaining 192 bits are user-programmable. Once programmed, the entire Security ID can be permanently locked using the Lockout SID command, setting the SEC bit in the status register to '1'. This lock is irreversible and prevents further writes, as specified in the "Security ID" section of the SST25VF064C-80-4I-SCE datasheet.
What erase options are available for SST25VF064C-80-4I-SCE?
The SST25VF064C-80-4I-SCE supports three erase granularities: sector-erase (4 KByte), block-erase (32 KByte or 64 KByte), and chip-erase. Erase times are 18 ms (sector/block) and 35 ms (chip), all typical values. These options allow precise firmware updates without affecting unrelated memory regions - a critical capability for field-upgradable systems relying on the SST25VF064C-80-4I-SCE.
