Product details
Overview
SST25VF010A-33-4C-SAE-T from Microchip Technology is a 1 Mbit SPI serial flash memory IC designed for embedded firmware storage and boot code retention in microcontroller-based systems. It operates at 2.7–3.6 V, supports up to 33 MHz clock frequency, features uniform 4 KByte sectors and 32 KByte overlay blocks, and delivers 100,000 program/erase cycles with >100 years data retention - deployed in industrial control panels requiring nonvolatile configuration storage.
For engineers reviewing the SST25VF010A-33-4C-SAE-T datasheet, SST25VF010A-33-4C-SAE-T pinout, SST25VF010A-33-4C-SAE-T application, or SST25VF010A-33-4C-SAE-T equivalent, key selection criteria include SPI Mode 0/3 compatibility, SOIC-8 package footprint, 8 µA standby current, software/hardware write protection (WP#/HOLD#), and Auto Address Increment (AAI) programming for efficient firmware updates.
Technical Context
The SST25VF010A-33-4C-SAE-T implements a four-wire SPI interface (SCK, SI, SO, CE#) with dual-mode support (Mode 0 and Mode 3), enabling interoperability with diverse host controllers without protocol translation. Its SuperFlash technology uses a split-gate cell and thick-oxide tunneling injector, delivering faster erase times (18 ms sector-erase, 70 ms chip-erase) and lower total energy per operation versus conventional NOR flash.
It integrates dedicated hardware pins for HOLD# (suspend ongoing SPI transfers without deselecting) and WP# (enable/disable status register lock-down), alongside a software-configurable status register with BUSY, WEL, BP0/BP1, and BPL bits - allowing fine-grained, persistent block protection across 0%, 25%, 50%, or 100% of the 1 Mbit array.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 Mbit (131,072 bytes), organized as 32 × 4 KByte sectors or 4 × 32 KByte overlay blocks - enables modular firmware partitioning and field-upgradable bootloader sections. |
| Max Clock Frequency | 33 MHz (High-Speed Read mode), enabling 4.125 MB/s sequential read throughput - suitable for fast boot code loading in real-time systems. |
| Supply Voltage | 2.7–3.6 V single supply - compatible with 3.3 V logic domains and eliminates need for level-shifting in most MCU interfaces. |
| Endurance & Retention | 100,000 program/erase cycles typical; >100 years data retention at +25°C - meets long-life requirements for industrial equipment with infrequent firmware updates. |
| Active/Standby Current | 7 mA typical active read current; 8 µA typical standby current - reduces power budget impact in battery-backed or energy-constrained edge devices. |

Pinout & Package
Package: 8-lead SOIC (150 mil body width), RoHS-compliant, lead-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CE# | Chip Enable | Active-low device select signal; must remain low throughout command execution - enables multi-device SPI bus sharing with hardware address decoding. |
| SO | Serial Data Output | Tri-state output driven on SCK falling edge - provides high-impedance isolation when not selected, preventing bus contention. |
| WP# | Write Protect | Hardware enable for status register lock-down (BPL bit); when low, prevents accidental modification of BP0/BP1 protection bits - critical for secure firmware update workflows. |
| VSS | Ground | Reference return path for all digital and analog circuitry - requires low-impedance PCB connection to minimize noise coupling into SPI signaling. |
| VDD | Power Supply | 2.7–3.6 V input; decoupling capacitor (0.1 µF) required near pin to suppress switching transients during high-speed read/write operations. |
| HOLD# | Hold | Pauses ongoing SPI transaction without resetting internal state or clock sequence - allows host CPU to service interrupts while preserving flash access context. |
| SCK | Serial Clock | Master-generated timing signal; data sampled on rising edge (SI), output shifted on falling edge (SO) - defines timing margins for setup/hold compliance. |
| SI | Serial Data Input | Command, address, or data input latched on SCK rising edge - supports standard SPI opcodes (03H Read, 0BH High-Speed Read, 02H Byte-Program, etc.). |
Key Features
| Feature | Design Value |
|---|---|
| Auto Address Increment (AAI) Programming | Reduces total programming time by eliminating repeated address transmission - ideal for sequential firmware image writes without host-side address management overhead. |
| Dual SPI Mode Support (Mode 0 & Mode 3) | Ensures plug-and-play compatibility with ARM Cortex-M, PIC, and legacy MCU SPI peripherals - no firmware rework needed when migrating between controller families. |
| Flexible Block Protection Scheme | Four software-selectable protection levels (0%, 25%, 50%, 100% array) via BP0/BP1 bits - enables independent locking of bootloader, application, and configuration sectors. |
| Hardware HOLD# and WP# Pins | Enables deterministic pause/resume of SPI transfers and irreversible status register lockdown - satisfies functional safety requirements for fail-safe firmware recovery paths. |
| SuperFlash Technology | Delivers superior reliability (100K cycles, >100 yr retention) and lower energy-per-operation versus standard NOR flash - extends product lifetime in unattended deployments. |

FAQ
What is the maximum operating clock frequency supported by the SST25VF010A-33-4C-SAE-T?
The SST25VF010A-33-4C-SAE-T supports a maximum clock frequency of 33 MHz in High-Speed Read mode (command 0BH), enabling sustained read throughput of 4.125 MB/s. Standard Read mode (command 03H) is rated at 20 MHz. This 33 MHz rating is guaranteed across the commercial temperature range (0°C to +70°C) and applies specifically to the -33 speed grade variant of the SST25VF010A-33-4C-SAE-T.
Does the SST25VF010A-33-4C-SAE-T support both SPI Mode 0 and Mode 3?
Yes, the SST25VF010A-33-4C-SAE-T explicitly supports both SPI Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1), as confirmed in its official datasheet. This dual-mode compatibility ensures seamless integration with a wide range of microcontrollers - including legacy 8-bit MCUs and modern ARM Cortex-M series - without requiring protocol translation or custom driver logic for the SST25VF010A-33-4C-SAE-T.
How does the HOLD# pin function on the SST25VF010A-33-4C-SAE-T?
The HOLD# pin on the SST25VF010A-33-4C-SAE-T suspends an ongoing SPI transaction without deselecting the device or resetting internal state. When asserted low (while CE# remains low), it places SO in high-impedance and pauses clock synchronization - allowing the host processor to service interrupts or perform other tasks before resuming communication. This behavior is fully defined in the SST25VF010A-33-4C-SAE-T datasheet Figure 3 and timing specification.
What write protection mechanisms are available on the SST25VF010A-33-4C-SAE-T?
The SST25VF010A-33-4C-SAE-T provides three-tiered write protection: (1) hardware WP# pin to enable/disable status register lock-down, (2) software-configurable BP0/BP1 bits for 0%/25%/50%/100% array protection, and (3) BPL bit to permanently lock BP0/BP1 once set. These mechanisms operate independently and concurrently - for example, WP# low + BPL=1 prevents any status register modification, while WP# high allows full software control of protection levels in the SST25VF010A-33-4C-SAE-T.
Is the SST25VF010A-33-4C-SAE-T pin-compatible with other 8-lead SOIC SPI flash devices?
The SST25VF010A-33-4C-SAE-T uses the industry-standard 8-lead SOIC (150 mil) pinout: Pin 1 = CE#, Pin 2 = SO, Pin 3 = WP#, Pin 4 = VSS, Pin 5 = VDD, Pin 6 = HOLD#, Pin 7 = SCK, Pin 8 = SI. While physically pin-compatible with many SPI flash devices in the same package, functional compatibility depends on instruction set, timing, and feature support - e.g., the SST25VF010A-33-4C-SAE-T's AAI programming and HOLD# behavior are not universally replicated.
