Product details
Overview
SST25VF080B-80-4C-S2AE from Microchip Technology is an 8 Mbit SPI serial flash memory IC with 80 MHz high-speed read capability, single 2.7–3.6 V supply operation, and SuperFlash® technology enabling 100,000 program/erase cycles. It features uniform 4 KByte sectors, 32/64 KByte overlay blocks, and supports SPI Mode 0/3 for embedded firmware storage in microcontroller boot applications.
For engineers reviewing the SST25VF080B-80-4C-S2AE datasheet, SST25VF080B-80-4C-S2AE pinout, SST25VF080B-80-4C-S2AE application, or SST25VF080B-80-4C-S2AE equivalent, key selection criteria include 80 MHz high-speed read timing, 4 KByte sector erase granularity, HOLD#/WP# hardware control, AAI programming efficiency, and industrial temperature range (–40°C to +85°C) compliance.
Technical Context
The SST25VF080B-80-4C-S2AE 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® split-gate cell architecture delivers faster erase times (18 ms sector-erase typical) and lower active current (10 mA typical) versus conventional NOR flash.
Hardware flow control is implemented via dedicated HOLD# (suspend ongoing serial sequence without deselecting) and WP# (enable/disable status register lock-down), while end-of-write detection is supported both by software polling of the BUSY bit and hardware RY/BY# output on SO during AAI programming after EBSY command execution.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 8 Mbit (1,048,576 bytes), organized as 256 uniform 4 KByte erasable sectors |
| Max Read Frequency | 80 MHz using High-Speed Read (0BH) instruction with dummy cycle - enables <12.5 ns effective access time for real-time firmware fetch |
| Write Endurance | 100,000 program/erase cycles typical - supports frequent field firmware updates over product lifetime |
| Data Retention | Greater than 100 years at +25°C - ensures long-term reliability for unattended embedded systems |
| Supply Voltage | 2.7 V to 3.6 V single supply - compatible with 3.3 V logic domains without level-shifting |
| Operating Temp | –40°C to +85°C (Industrial grade) - validated for automotive body control, industrial HMI, and outdoor IoT gateways |
| Active Read Current | 10 mA typical at 80 MHz - reduces power budget impact during boot code execution |
| Standby Current | 5 µA typical - enables ultra-low-power sleep modes in battery-backed applications |
Pinout & Package
Package: 8-lead SOIC (200 mils), RoHS-compliant, surface-mount.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CE# | Chip Enable | Active-low device select; must remain low throughout full instruction sequence (e.g., Read, Erase, Program) |
| SO | Serial Data Output | Outputs data on falling SCK edge; reconfigurable as RY/BY# status indicator during AAI programming after EBSY command |
| WP# | Write Protect | Enables/disables BPL bit lock-down; when low, prevents modification of Block-Protection bits unless BPL = 0 |
| VSS | Ground | Reference return path for all digital and analog circuitry; requires low-impedance PCB connection |
| VDD | Power Supply | 2.7–3.6 V supply input; decoupling capacitor (0.1 µF) required within 5 mm of pin per layout guidelines |
| HOLD# | Hold Control | Suspends ongoing SPI transaction (e.g., multi-byte Read) without resetting internal address pointer or clock state |
| SCK | Serial Clock | Provides timing reference; rising edge latches SI input, falling edge outputs SO data; supports Mode 0 (idle low) and Mode 3 (idle high) |
| SI | Serial Data Input | Accepts opcodes, addresses, and data MSB-first; sampled on rising SCK edge |
Key Features
| Feature | Design Value |
|---|---|
| Auto Address Increment (AAI) Programming | Reduces total programming time by eliminating repeated address transmission - supports sequential word programming with single ADH command per 2-byte payload |
| Flexible Erase Granularity | Independent 4 KByte sector, 32 KByte block, and 64 KByte block erase - enables precise firmware partitioning (e.g., bootloader vs. application image) |
| Hardware End-of-Write Detection | SO pin outputs RY/BY# status during AAI mode after EBSY (70H) command - eliminates software polling overhead and improves deterministic timing |
| Software Write Protection | Configurable BP3–BP0 bits in status register protect memory regions from accidental overwrite - supports hierarchical protection (e.g., lock bootloader while allowing app update) |
| SuperFlash® Technology | Split-gate cell with thick-oxide tunneling injector achieves 35 ms chip-erase (typical) and 7 µs byte-program - lowers energy per operation vs. standard NOR flash |
Applications
| Boot Code Storage | Firmware Update Storage |
|---|---|

IC Role / Device Role / Timing Role: Secure non-volatile storage with software block protection (BP bits) and hardware WP# lock-down to prevent unauthorized key overwrite. Use Value: Meets PCI PTS requirements for key isolation; BPL bit prevents permanent disablement of protection once enabled. |
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, but lacks HOLD# pin and AAI programming mode | Requires host-side address management for multi-byte writes; no hardware suspend capability for interrupt-driven systems | Select when higher speed or QSPI interface is needed; avoid if HOLD# or AAI efficiency is critical |
| Macronix MX25L8006EM1I-12G | 8 Mbit, 80 MHz max read, supports SPI Mode 0/3 and HOLD#, but uses standard NOR cell (no SuperFlash®) | Higher program/erase energy consumption; 10,000-cycle endurance vs. 100,000 for SST25VF080B-80-4C-S2AE | Select for cost-sensitive designs where endurance >10k cycles is not required; verify thermal derating in industrial ambient |
Compared with W25Q80DVSSIG and MX25L8006EM1I-12G, the SST25VF080B-80-4C-S2AE uniquely combines 80 MHz read performance with AAI programming, HOLD# suspend, and 100k-cycle endurance - making it optimal for resource-constrained, field-upgradable embedded systems demanding long-term reliability.

FAQ
What is the maximum clock frequency supported by SST25VF080B-80-4C-S2AE for high-speed read operations?
The SST25VF080B-80-4C-S2AE supports up to 80 MHz for high-speed read operations using the 0BH instruction with a dummy byte. This is confirmed in Table 14 of the DS25045A datasheet and applies specifically to the "-80" suffix variant. The 80 MHz rating enables faster firmware loading compared to 50/66 MHz variants, reducing boot time in time-critical applications.
Does SST25VF080B-80-4C-S2AE support both SPI Mode 0 and Mode 3?
Yes, the SST25VF080B-80-4C-S2AE explicitly supports both SPI Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1), as stated in the "Device Operation" section of the DS25045A datasheet. This dual-mode compatibility allows seamless integration with a wide range of microcontrollers without requiring hardware modifications to the SPI peripheral configuration.
How does the HOLD# pin function in SST25VF080B-80-4C-S2AE, and what is its timing requirement?
The HOLD# pin in SST25VF080B-80-4C-S2AE suspends an ongoing SPI transaction (e.g., multi-byte read) without deselecting the device or resetting the internal address pointer. Per Figure 4 and the "Hold Operation" section, HOLD# must be asserted coincident with SCK's active-low state; if misaligned, suspension occurs at the next SCK low state. SO enters high-impedance during hold, preserving signal integrity.
What erase granularities are available on SST25VF080B-80-4C-S2AE, and how are they selected?
The SST25VF080B-80-4C-S2AE supports three erase granularities: 4 KByte sectors (20H instruction), 32 KByte blocks (52H), and 64 KByte blocks (D8H). Selection is determined solely by the opcode used - no configuration register setting is required. Each instruction accepts a base address aligned to its respective boundary (e.g., A12 for sector, A15 for 32K block), with unneeded upper address bits treated as "don't care."
Can SST25VF080B-80-4C-S2AE be used in industrial temperature applications?
Yes, the "-4C" suffix in SST25VF080B-80-4C-S2AE denotes Industrial temperature grade (–40°C to +85°C), explicitly confirmed in the "Features" and "Product Description" sections of DS25045A. This rating is validated across all electrical specifications including 80 MHz read timing, 100,000-cycle endurance, and 5 µA standby current, making it suitable for harsh-environment deployments.
