Product details
Overview
SST25VF064C-80-4C-Q2AE 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 80 MHz high-speed read (0BH), 75 MHz fast-read dual-output (3BH), and 50 MHz fast-read dual I/O (BBH) modes. It features uniform 4 KByte sectors, 32/64 KByte overlay blocks, 256-byte page programming, and integrated Security ID (64-bit factory-unique + 192-bit user-programmable).
For engineers reviewing the SST25VF064C-80-4C-Q2AE datasheet, SST25VF064C-80-4C-Q2AE pinout, SST25VF064C-80-4C-Q2AE application, or SST25VF064C-80-4C-Q2AE equivalent, key selection considerations include SPI Mode 0/3 compatibility, dual I/O timing constraints, sector/block erase granularity, write-protection via BP bits and WP# pin, and industrial temperature range (–40°C to +85°C) support.
Technical Context
The SST25VF064C-80-4C-Q2AE implements a four-wire SPI interface with CE#, SCK, SI/SIO0, and SO/SIO1 pins, enabling both single- and dual-I/O data transfer. Its SuperFlash technology uses split-gate cells and thick-oxide tunneling for enhanced endurance (100,000 cycles) and >100-year data retention.
It supports hardware reset and hold functions via the RST#/HOLD# pin, software status register (BUSY, WEL, BP0–BP3, BPL, SEC), and block protection levels configurable across 16 combinations - including full-array lock (BP3–BP0 = 1111) and partial upper-sector protection down to 1/128 of memory (7F0000H–7FFFFFH).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mbit (8 MByte), organized in uniform 4 KByte sectors |
| Supply Voltage | 2.7–3.6 V - enables direct integration with 3.3 V logic systems without level-shifting |
| Max Read Speed | 80 MHz (High-Speed Read, 0BH) - reduces instruction latency in boot code fetch scenarios |
| Erase Performance | 18 ms typical sector/block erase time - accelerates firmware update cycles |
| Page Program | 256 bytes per page, 1.5 ms typical - supports efficient incremental configuration storage |
| Endurance & Retention | 100,000 program/erase cycles; >100 years data retention - suitable for industrial logging and infrequent field updates |
| Temperature Range | –40°C to +85°C (Industrial grade) - validated for operation in extended ambient environments |
Pinout & Package
Package: 8-contact WSON (6 mm × 8 mm), RoHS-compliant, lead-free, moisture-sensitive level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CE# | Chip Enable | Active-low device select; must remain low throughout command execution 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) during dual I/O reads/writes |
| SO/SIO1 | Serial Output / Dual I/O Lane 1 | Outputs data or odd bits (D7,D5,D3,D1); switches to bidirectional mode in dual I/O instructions |
| WP# | Write Protect | Enables BPL bit lock-down; when low, prevents modification of BP3–BP0 unless BPL = 0 |
| RST#/HOLD# | Reset or Hold Control | Default reset function at power-up; EHLD instruction converts to hold mode to pause SPI without clock reset |
| VDD | Power Supply | 2.7–3.6 V supply; decoupling capacitor required near pin for stable high-frequency read operation |
| VSS | Ground | Reference return path; must be low-impedance to minimize noise on SCK/SI/SO lines |
Key Features
| Feature | Design Value |
|---|---|
| Dual I/O Read Acceleration | 50 MHz Fast-Read Dual I/O (BBH) cuts address+data clock cycles by 50% vs standard SPI, improving throughput in bandwidth-constrained designs |
| Flexible Block Protection | 16-level software-configurable protection (BP3–BP0) allows selective locking of upper memory regions - critical for secure bootloader partitioning |
| Security ID Space | 256-bit OTP Security ID (64-bit unique factory ID + 192-bit user space) enables device authentication and firmware binding |
| Low-Power Standby | 5 µA typical standby current - extends battery life in always-on IoT sensor nodes between wake events |
| SuperFlash Reliability | Split-gate cell architecture delivers 100× better endurance than conventional NOR flash, reducing field failure risk in mission-critical firmware storage |

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, no dual-I/O-only mode; different status register layout and security ID implementation | Lacks dedicated dual-I/O instruction set; requires QSPI controller; no factory-programmed unique ID | Choose for higher bandwidth where quad mode is available and unique ID not required |
| Macronix MX25L6433FZNI-10G | 64 Mbit, 104 MHz max read, supports DTR mode, different BP bit mapping and hold timing behavior | Requires tighter setup/hold on HOLD# signal; no integrated Security ID; different erase suspend/resume capability | Choose when DTR interface is needed and security ID is unnecessary |
Compared with SST25VF064C-80-4C-Q2AE, W25Q64JVSSIQ offers higher peak bandwidth but lacks factory-unique ID and dual-I/O optimization, while MX25L6433FZNI-10G supports DTR for doubled data rate but omits hardware security features - making SST25VF064C-80-4C-Q2AE optimal for cost-sensitive industrial designs requiring guaranteed device identity and deterministic dual-I/O timing.

FAQ
What is the maximum clock frequency supported by SST25VF064C-80-4C-Q2AE for standard SPI read operations?
The SST25VF064C-80-4C-Q2AE supports up to 80 MHz for High-Speed Read (0BH instruction), 75 MHz for Fast-Read Dual-Output (3BH), 50 MHz for Fast-Read Dual I/O (BBH), and 33 MHz for standard Read (03H). The "80" in the part number explicitly denotes the 80 MHz high-speed read capability, verified in the official Microchip datasheet DS20005036C.
Does SST25VF064C-80-4C-Q2AE support SPI Mode 0 and Mode 3 simultaneously?
Yes, SST25VF064C-80-4C-Q2AE is fully compatible with both SPI Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1), as confirmed in the "Device Operation" section of the datasheet. The device samples SI on the rising edge and drives SO on the falling edge in both modes, differing only in idle SCK state - enabling interoperability with diverse host controllers.
How is write protection implemented on SST25VF064C-80-4C-Q2AE?
SST25VF064C-80-4C-Q2AE implements dual-layer write protection: hardware via the WP# pin (enabling BPL bit lock-down), and software via BP3–BP0 bits in the status register. When WP# is low and BPL=1, BP bits become read-only; otherwise, WRSR can modify them. This allows hierarchical protection - e.g., locking bootloader sectors while permitting runtime config updates in unprotected regions.
What package type does SST25VF064C-80-4C-Q2AE use, and is it RoHS compliant?
SST25VF064C-80-4C-Q2AE uses an 8-contact WSON (6 mm × 8 mm) package, as specified in the "Packages Available" section of the datasheet. All variants, including this one, are RoHS compliant and lead-free, with moisture sensitivity level (MSL) 3 - requiring bake-out if exposed beyond floor life before reflow.
Can SST25VF064C-80-4C-Q2AE be used in industrial temperature environments?
Yes, SST25VF064C-80-4C-Q2AE is rated for the industrial temperature range of –40°C to +85°C, explicitly stated in the "Features" and "Product Description" sections of the datasheet. This makes it suitable for deployment in programmable logic controllers, motor drives, and outdoor infrastructure equipment without thermal derating.
