Product details
Overview
SST25VF080B-80-4C-SAE 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 supports uniform 4 KByte sectors and 32/64 KByte overlay blocks, and is used for firmware storage in embedded microcontroller boot loaders.
For engineers reviewing the SST25VF080B-80-4C-SAE datasheet, SST25VF080B-80-4C-SAE pinout, SST25VF080B-80-4C-SAE application, or SST25VF080B-80-4C-SAE equivalent, key selection criteria include 80 MHz high-speed read timing, SOIC-8 (200 mil) package compatibility, hardware/software end-of-write detection support, and industrial temperature range (-40°C to +85°C) compliance.
Technical Context
The SST25VF080B-80-4C-SAE implements a four-wire SPI interface compliant with Mode 0 and Mode 3 protocols, using SCK, SI, SO, CE#, WP#, and HOLD# signals for command, address, and data transfer. Its SuperFlash® split-gate cell architecture enables faster erase (18 ms sector-erase typical) and lower total energy per operation versus conventional flash.
It features dual end-of-write detection: software polling of BUSY bit in Status Register (bit 0), and hardware RY/BY# status output on SO during Auto Address Increment (AAI) programming via EBSY/DBSY commands. Block protection is managed through BP3–BP0 bits with lock-down control via BPL and WP# pin.

IC Role / Device Role / Timing Role: High-bandwidth SPI flash accessed by display controller DMA for rapid asset loading. Use Value: 80 MHz read rate delivers >10 MB/s effective throughput - sufficient for 720p bitmap streaming. |
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 W25Q80DVSSIG | 8 Mbit, 104 MHz max read, Quad SPI capable, but lacks AAI programming and hardware RY/BY# on SO | Requires host-side address management for multi-byte writes; no hardware busy indication during programming | Preferred when Quad SPI bandwidth or higher clock speed is required, and AAI/hardware detection is not needed |
| Macronix MX25L8006EM1I-12G | 8 Mbit, 80 MHz max read, supports AAI but uses different status register layout and lacks HOLD# pin functionality | Requires firmware adaptation for status bit interpretation and hold behavior; no dedicated suspend-on-HOLD# feature | Selected when cost sensitivity outweighs need for HOLD#-based transaction pausing in real-time systems |
Compared with SST25VF080B-80-4C-SAE, W25Q80DVSSIG offers higher read bandwidth but sacrifices AAI efficiency and hardware end-of-write signaling, while MX25L8006EM1I-12G matches read speed and AAI support but omits HOLD#-a critical feature for deterministic SPI transaction control in interrupt-driven firmware.

FAQ
What is the maximum operating frequency of the SST25VF080B-80-4C-SAE?
The SST25VF080B-80-4C-SAE supports up to 80 MHz for High-Speed Read operations using the 0BH command. This is confirmed in Table 14 of the DS25045A datasheet and applies specifically to the "-80" suffix variant. The standard Read (03H) instruction operates up to 33 MHz. The 80 MHz rating enables faster firmware loading and GUI asset retrieval in time-critical embedded systems.
Does the SST25VF080B-80-4C-SAE support both SPI Mode 0 and Mode 3?
Yes, the SST25VF080B-80-4C-SAE is fully compatible with both SPI Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1), as explicitly stated in the Product Description and Device Operation sections of DS25045A. This dual-mode support ensures interoperability with a wide range of host processors, including legacy and modern microcontrollers without requiring hardware-level SPI configuration changes.
What package type does the SST25VF080B-80-4C-SAE use?
The SST25VF080B-80-4C-SAE uses an 8-lead SOIC package with 200 mil body width (standard JEDEC MS-012), as specified in the "Packages Available" section and Figure 2 of DS25045A. The "-SAE" suffix denotes this specific SOIC-200mil industrial-grade variant, distinguishing it from WSON, PDIP, or 150-mil SOIC versions of the same base part.
How does the HOLD# pin function on the SST25VF080B-80-4C-SAE?
The HOLD# pin on the SST25VF080B-80-4C-SAE suspends an active SPI transaction without resetting internal state or requiring CE# deassertion. As defined in Section 6 of DS25045A, HOLD# activation occurs when its falling edge coincides with SCK's active-low state, placing SO in high-impedance while preserving address and command context - essential for deterministic interrupt handling in real-time firmware.
What is the endurance and data retention specification for the SST25VF080B-80-4C-SAE?
The SST25VF080B-80-4C-SAE guarantees 100,000 program/erase cycles minimum and greater than 100 years of data retention at 25°C, as documented in the Features section and Table 1 of DS25045A. These values are measured under standard operating conditions (2.7–3.6 V, -40°C to +85°C) and reflect the reliability advantage of Microchip's SuperFlash® technology over conventional NOR flash.
