Product details
Overview
SST25VF080B-80-4C-QAE from Microchip Technology is an 8 Mbit SPI serial flash memory IC with SuperFlash technology, supporting 80 MHz high-speed read operations, 2.7–3.6 V single-supply operation, and uniform 4 KByte/32 KByte/64 KByte erase granularity. It serves as non-volatile program/data storage in microcontroller boot loaders, firmware update partitions, and embedded configuration memory.
For engineers reviewing the SST25VF080B-80-4C-QAE datasheet, SST25VF080B-80-4C-QAE pinout, SST25VF080B-80-4C-QAE application, or SST25VF080B-80-4C-QAE equivalent, key selection criteria include SPI Mode 0/3 compatibility, hardware/software end-of-write detection support, AAI programming capability, and industrial temperature range (–40°C to +85°C) for ruggedized designs.
Technical Context
The SST25VF080B-80-4C-QAE implements a four-wire SPI interface (SCK, SI, SO, CE#) with dual-mode clock polarity support (Mode 0 and Mode 3), enabling interoperability with diverse host controllers. Its internal SuperFlash architecture uses split-gate cells and thick-oxide tunneling injectors to achieve 100,000 program/erase cycles and >100 years data retention.
It supports three erase granularities-4 KByte sectors, 32 KByte blocks, and 64 KByte blocks-and features Auto Address Increment (AAI) word-programming to reduce sequential write latency. End-of-write detection is implemented via both software polling of the BUSY bit and hardware RY/BY# status output on SO during AAI mode when enabled by EBSY (70H) command.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 8 Mbit (1 MByte), directly addressable up to 0xFFFFF; enables compact firmware storage without external address latching |
| Max Read Frequency | 80 MHz (High-Speed Read mode with dummy cycle), doubling throughput vs. standard 40 MHz SPI flash in bandwidth-constrained systems |
| Supply Voltage | 2.7–3.6 V single supply; compatible with 3.3 V logic domains and eliminates need for level shifters in most MCU interfaces |
| Erase Granularity | Uniform 4 KByte sectors, 32 KByte blocks, 64 KByte blocks; allows fine-grained firmware partitioning and OTA update safety |
| Endurance & Retention | 100,000 program/erase cycles typical; >100 years data retention at +85°C - validated for long-life industrial deployments |
| Operating Temperature | –40°C to +85°C (Industrial grade); qualified for automotive body control modules and industrial HMIs |
| Active Read Current | 10 mA typical at 80 MHz; enables low-power active reads in battery-backed or energy-harvesting applications |
| Standby Current | 5 µA typical; supports ultra-low-power sleep modes in always-on edge devices |
Pinout & Package
Package: 8-contact WSON (6 mm × 5 mm), RoHS-compliant, moisture-sensitive level 3 (MSL3). Pin-compatible with industry-standard 8-pin SPI flash footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CE# | Chip Enable | Active-low device select; must remain low throughout full instruction sequence; deassertion resets internal logic |
| SO | Serial Data Output / RY/BY# | Tri-state output for read data; reconfigurable as hardware busy indicator (0 = busy, 1 = ready) during AAI mode when EBSY enabled |
| WP# | Write Protect | Enables lock-down of Block-Protection bits (BP3–BP0) via BPL bit; low = BPL functional, high = BPL disabled |
| HOLD# | Hold Control | Suspends ongoing SPI transaction without deselecting device; requires CE# low and SCK low-edge alignment for entry/exit |
| SCK | Serial Clock | Edge-triggered timing source; rising edge latches SI, falling edge shifts out SO; supports Mode 0 (idle low) and Mode 3 (idle high) |
| SI | Serial Data Input | Command, address, and data input path; MSB-first, synchronous to SCK rising edge |
| VDD | Power Supply | 2.7–3.6 V core and I/O supply; decoupling capacitor required per datasheet layout guidelines |
| VSS | Ground | Reference return path; must be low-impedance connection to minimize noise coupling into SO/SI signals |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash Technology | Split-gate cell + thick-oxide injector delivers 10× faster erase vs. conventional NOR flash and superior cycling reliability |
| Auto Address Increment (AAI) | Reduces sequential byte-program time by eliminating repeated address transmission; supports continuous 2-byte word writes |
| Dual End-of-Write Detection | Hardware RY/BY# on SO (via EBSY/DBSY) avoids CPU polling overhead; software BUSY-bit polling provides fallback flexibility |
| Flexible Block Protection | Four BP bits enable 7 protection levels (none to full chip), with lock-down via WP#-controlled BPL bit for secure firmware lockdown |
| Industrial Temp Range | –40°C to +85°C operation verified across voltage and frequency corners; suitable for under-hood and factory-floor environments |
| RoHS & Green Compliance | Lead-free, halogen-free WSON package meets global environmental regulations without derating or thermal penalty |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPI serial flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Winbond W25Q80DVSSIG | 8 Mbit, 104 MHz max read, Quad SPI capable; lacks HOLD# pin and AAI programming | Higher throughput in QSPI-configured hosts; not drop-in for legacy SST25VF080B-80-4C-QAE designs using HOLD# or AAI | Select if migrating to QSPI interface and requiring faster random reads; verify HOLD#/AAI removal in firmware |
| Cypress S25FL008A0XMFI00 | 8 Mbit, 66 MHz max read, supports SFDP; includes security register but no hardware RY/BY# on SO | Better standardized configuration discovery via SFDP; requires software polling only for end-of-write detection | Prefer for new designs needing JEDEC-standardized initialization; avoid if hardware busy signaling is critical for real-time response |
Compared with W25Q80DVSSIG and S25FL008A0XMFI00, the SST25VF080B-80-4C-QAE uniquely combines 80 MHz read speed with HOLD#, AAI, and configurable RY/BY#-making it optimal for resource-constrained industrial controllers where deterministic timing and legacy SPI compatibility are mandatory.

FAQ
What is the maximum clock frequency supported by SST25VF080B-80-4C-QAE for high-speed read operations?
The SST25VF080B-80-4C-QAE supports up to 80 MHz for High-Speed Read operations using the 0BH command with a dummy byte. This is confirmed in Table 14 of DS25045A and applies specifically to the "-80" suffix variant. Standard Read (03H) operates up to 33 MHz. The 80 MHz capability enables faster firmware loading and GUI asset streaming in bandwidth-limited SPI buses.
Does SST25VF080B-80-4C-QAE support both SPI Mode 0 and Mode 3?
Yes, SST25VF080B-80-4C-QAE explicitly supports both SPI Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1), as stated in the "Serial Interface Architecture" section of DS25045A. This dual-mode compatibility ensures interoperability with a wide range of microcontrollers-including older PIC and AVR families-that may default to either mode without requiring hardware modification.
How does the HOLD# pin function in SST25VF080B-80-4C-QAE, and what are its timing requirements?
The HOLD# pin in SST25VF080B-80-4C-QAE suspends an ongoing SPI transaction without deselecting the device. Entry requires CE# low and HOLD# falling edge aligned with SCK low state; exit requires HOLD# rising edge aligned with SCK low state. If misaligned, the device enters/exits hold on the next SCK low transition. This behavior is defined in Figure 4 and Section "Hold Operation" of DS25045A.
What erase block sizes are available in SST25VF080B-80-4C-QAE, and how are they selected?
SST25VF080B-80-4C-QAE supports three uniform erase granularities: 4 KByte sectors (20H command, AMS–A12 used), 32 KByte blocks (52H command, AMS–A15 used), and 64 KByte blocks (D8H command, AMS–A16 used). Address bits beyond the required MSBs are don't-care (VIL or VIH). This flexibility allows optimized partitioning-for example, 4 KByte for config storage and 64 KByte for firmware images.
Can SST25VF080B-80-4C-QAE be used in industrial temperature applications, and what is its rated range?
Yes, SST25VF080B-80-4C-QAE is rated for industrial temperature operation from –40°C to +85°C, as specified in the "Temperature Range" section of DS25045A. The "-4C" suffix denotes the industrial grade. This qualification covers full electrical performance-including 80 MHz read speed, 100,000-cycle endurance, and 5 µA standby current-across the entire range, making it suitable for factory automation and outdoor metering.
