Product details
Overview
SST25WF080BT-40I/NP from Microchip Technology is an 8 Mbit, 1.65–1.95V SPI serial flash memory IC with SuperFlash technology, supporting 40 MHz high-speed read, dual-output and dual I/O modes, and industrial temperature operation (–40°C to +85°C). It delivers ultra-low power consumption (7 µA standby, 2 µA deep power-down) and integrates hardware HOLD# and WP# pins for real-time command suspension and block-level write protection in embedded firmware storage applications.
For engineers reviewing the SST25WF080BT-40I/NP datasheet, SST25WF080BT-40I/NP pinout, SST25WF080BT-40I/NP application, or SST25WF080BT-40I/NP equivalent, key selection criteria include its 1.8V single-supply operation, 256-byte page programming, uniform 4 KByte sector/64 KByte block erase architecture, AEC-Q100 qualification, and compatibility with SPI Modes 0 and 3 in space-constrained industrial and automotive control systems.
Technical Context
The SST25WF080BT-40I/NP implements a four-wire SPI interface with dedicated SI/SO pins and dual-capable SIO0/SIO1 terminals, enabling Fast-Read Dual-Output (3BH) and Fast-Read Dual I/O (BBH) instructions for doubled data throughput at 40 MHz. Its internal SuperFlash split-gate cell architecture enables faster erase times (40 ms sector, 80 ms block) and higher endurance (100,000 cycles) versus conventional NOR flash.
Control logic includes a software status register with BUSY (bit 0), WEL (bit 1), and configurable BP0–BP2/TB/BPL bits for non-volatile block protection, while hardware HOLD# suspends active sequences without deselecting CE#, and WP# enables BPL lock-down for secure firmware update partitions.
Key Specifications

Pinout & Package
Package: 8-lead SOIC (150 mil), RoHS-compliant, surface-mount.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CE# | Chip Enable | Active-low device select; must remain low throughout instruction sequence; drives device into standby when high |
| SO/SIO1 | Serial Data Output / Dual I/O | Outputs MSB-first data during read; functions as input for odd address bits in Dual I/O mode (BBH) |
| WP# | Write Protect | Enables BPL bit lock-down; when low, prevents modification of BP0–BP2/TB/BPL bits in status register |
| VSS | Ground | Reference return path for all digital and analog circuitry; requires low-impedance PCB connection |
| VDD | Power Supply | 1.65–1.95V supply input; decoupling capacitor (0.1 µF) required near pin for stable core voltage |
| HOLD# | Hold Control | Pauses ongoing SPI transaction without resetting clock state; requires synchronous falling edge with SCK low |
| SCK | Serial Clock | Timing reference for all SPI transfers; supports Mode 0 (SCK idle low) and Mode 3 (SCK idle high) |
| SI/SIO0 | Serial Data Input / Dual I/O | Accepts commands, addresses, and data; functions as input for even address bits in Dual I/O mode (BBH) |
Key Features
| Feature | Design Value |
|---|---|
| Dual I/O Interface Support | Enables BBH instruction for simultaneous 2-bit address input and 2-bit data output per clock cycle, reducing instruction latency by ~50% vs standard SPI |
| Flexible Block Protection | Configurable via status register BP0–BP2/TB bits to protect 1/16 to full memory array - supports secure bootloader partitioning |
| Ultra-Low Deep Power-Down | 2 µA typical current draw allows battery-backed retention in always-on monitoring nodes without compromising runtime |
| SuperFlash Technology | Split-gate cell design achieves 40 ms sector erase (vs >100 ms in legacy flash), lowering total energy per erase by >60% |
| HOLD# Pin Functionality | Permits interruption of multi-byte read/write sequences mid-transfer - critical for deterministic real-time interrupt handling |

FAQ
What is the maximum clock frequency supported by SST25WF080BT-40I/NP for high-speed read operations?
The SST25WF080BT-40I/NP supports up to 40 MHz for High-Speed Read (0BH), Fast-Read Dual-Output (3BH), and Fast-Read Dual I/O (BBH) instructions. Standard Read (03H) is limited to 30 MHz. This 40 MHz capability enables faster firmware loading and real-time data retrieval in time-sensitive applications such as automotive boot sequences.
Does SST25WF080BT-40I/NP support both SPI Mode 0 and Mode 3?
Yes, SST25WF080BT-40I/NP is fully compatible with SPI Mode 0 (CPOL = 0, CPHA = 0) and Mode 3 (CPOL = 1, CPHA = 1). The device samples SI on the rising edge and drives SO on the falling edge of SCK in both modes, ensuring interoperability with diverse host controllers including ARM Cortex-M, Renesas RX, and Infineon Aurix families.
How does the HOLD# pin function during active SPI communication in SST25WF080BT-40I/NP?
In SST25WF080BT-40I/NP, the HOLD# pin suspends ongoing SPI transactions synchronously with SCK: hold begins on the falling edge of HOLD# coinciding with SCK low, and resumes on the rising edge of HOLD# also aligned with SCK low. During hold, SO enters high-impedance while SI and SCK remain valid - preserving command context for deterministic real-time interrupt handling.
What memory organization does SST25WF080BT-40I/NP use for erase operations?
The SST25WF080BT-40I/NP features uniform 4 KByte sectors (256 total) and 16 overlay 64 KByte blocks. Sector-Erase (20H/D7H) clears one 4 KByte sector in 40 ms typical; Block-Erase (D8H) clears one 64 KByte block in 80 ms typical; Chip-Erase (60H/C7H) clears the full 8 Mbit array in 500 ms typical - all verified under 1.8V supply conditions.
Is SST25WF080BT-40I/NP qualified for automotive applications?
Yes, SST25WF080BT-40I/NP is AEC-Q100 qualified for Grade 3 (–40°C to +85°C) operation and meets automotive reliability standards for endurance (100,000 cycles) and data retention (>20 years at +85°C). Its 1.8V operation, HOLD#/WP# pins, and dual I/O support make it suitable for engine control units, ADAS modules, and body electronics.
