Product details
Overview
AT25FS010N-SH27-T from Microchip Technology is a 1 Mbit (131,072 × 8) serial SPI Flash memory IC optimized for low-voltage industrial applications. It operates from 2.7V to 3.6V, supports 50 MHz clock rate, and features sector/block/page erase architecture with hardware write protection via WP pin and software block protection via status register. It is used in firmware storage for microcontroller-based embedded systems requiring reliable nonvolatile code/data retention.
For engineers reviewing the AT25FS010N-SH27-T datasheet, AT25FS010N-SH27-T pinout, AT25FS010N-SH27-T application, or AT25FS010N-SH27-T equivalent, this page delivers verified electrical specs, JEDEC SOIC-8 pin mapping, SPI Mode 0/3 timing compliance, endurance (10,000 write cycles), and real-world use cases in boot code storage, configuration data logging, and field-upgradable firmware modules.
Technical Context
The AT25FS010N-SH27-T implements a synchronous SPI slave interface with separate SI/SO lines, supporting both standard READ (03h) and FAST READ (0Bh) with dummy cycle. Its internal architecture divides memory into four uniform 32 KB blocks, each containing eight 4 KB sectors and 256-byte pages - enabling granular erase control without disturbing adjacent data.
It integrates Power-On Reset (POR) circuitry (~1.8 V threshold), self-timed erase/program cycles (sector erase: 50–200 ms; byte program: 30 µs typical), and dual write protection: hardware-level via WP pin (when WPEN=1) and software-level via BP0–BP4 bits in nonvolatile status register. All instructions are MSB-first with high-to-low CS activation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 1,048,576 bits (131,072 × 8), organized as 512 pages of 256 bytes each - enables efficient firmware partitioning and partial updates. |
| Supply Voltage | 2.7 V to 3.6 V - compatible with 3.3 V logic systems and supports brown-out tolerant operation down to 2.7 V. |
| Max Clock Frequency | 50 MHz - allows high-speed read access for boot-time code fetch and real-time data retrieval. |
| Write Endurance | 10,000 program/erase cycles per sector - sufficient for infrequent firmware upgrades and persistent configuration storage. |
| Erase Granularity | Sector (4 KB), Block (32 KB), or Chip (1 MB) - permits selective reprogramming without full device erase, reducing update latency. |
| Operating Temperature | –40°C to +85°C - qualified for industrial-grade embedded environments including motor controls and sensor nodes. |
| Package | 8-lead JEDEC SOIC (150 mil) - surface-mount compatible with standard PCB assembly processes and legacy footprint reuse. |
Pinout & Package
AT25FS010N-SH27-T is packaged in an 8-lead JEDEC-standard SOIC (150 mil width), pin-compatible with industry-standard serial flash footprints. The package supports reflow soldering and meets RoHS/lead-free requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip Select input | Active-low enable signal; must be held low during instruction/address/data transfer; drives device into standby when high. |
| SCK | Serial clock input | Synchronizes all data transfers; supports up to 50 MHz; requires stable edge timing (tWH/tWL ≥ 9 ns). |
| SI | Serial data input | Receives opcodes, addresses, and program data (MSB first); ignored during HOLD or internal write cycles. |
| SO | Serial data output | Drives read data, status register contents, or ID codes; enters high-impedance state when CS is high or HOLD is active. |
| GND | Ground reference | Primary return path for VCC current and signal references; must be low-inductance connection for noise immunity. |
| VCC | Power supply | 2.7–3.6 V DC input; includes internal POR circuit (~1.8 V threshold) to prevent spurious writes during power ramp. |
| WP | Hardware write protect | When WPEN=1 and WP pulled low, disables all status register writes - prevents accidental lockout of protected memory regions. |
| HOLD | Serial communication suspend | Pauses ongoing SPI transaction (e.g., mid-read) without resetting sequence; requires SCK low before assertion. |
Key Features
| Feature | Design Value |
|---|---|
| SPI Mode 0 & 3 compatibility | Supports both CPOL=0 CPHA=0 and CPOL=1 CPHA=1 - interoperable with diverse MCU SPI controllers without protocol translation. |
| Flexible block protection | Eight software-selectable protection levels (1/32 to full array) via nonvolatile BP0–BP4 bits - enables secure boot loader partitioning. |
| Self-timed erase/program | No external timing control needed; internal logic manages sector erase (200 ms max), block erase (500 ms max), and byte program (50 µs max). |
| JEDEC-standard RDID | Returns manufacturer ID (1Fh) and device ID (66h, 01h) via 9Fh/ABh opcodes - enables automatic part identification in production programming. |
| Low-power standby | 2.0–10.0 µA ISB at 2.7 V - reduces system quiescent current in battery-powered or energy-harvesting applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| W25Q80DVSSIG | 8 Mbit capacity, 104 MHz max clock, Quad SPI support, different status register layout and protection scheme. | Better suited for high-bandwidth code execution; lacks HOLD pin and uses different WP implementation. | Select when higher density or quad I/O bandwidth is required; verify software driver compatibility with new opcodes and protection model. |
| SST25VF010A-20-4I-SAE | 1 Mbit, 20 MHz max clock, no HOLD pin, simpler status register (BP0–BP2 only), 100,000 write cycles. | Lower performance and fewer protection options; targeted at cost-sensitive legacy designs. | Choose for pin-compatible drop-in where speed and advanced protection are not required; confirm timing margins for slower SCK. |
Compared with W25Q80DVSSIG and SST25VF010A-20-4I-SAE, AT25FS010N-SH27-T offers balanced 50 MHz throughput, robust dual-layer write protection, and industrial temperature support - making it optimal for firmware storage where reliability, moderate speed, and precise sector control outweigh raw density or ultra-high clock rates.

FAQ
What is the maximum clock frequency supported by AT25FS010N-SH27-T?
The AT25FS010N-SH27-T supports a maximum SCK clock frequency of 50 MHz, validated across the full operating temperature range (–40°C to +85°C) and supply voltage (2.7 V to 3.6 V). This enables high-speed read operations for boot code execution and real-time data access. Timing parameters such as tWH (9 ns min) and tWL (9 ns min) ensure reliable sampling at this rate.
Does AT25FS010N-SH27-T support SPI Mode 3 (CPOL=1, CPHA=1)?
Yes, AT25FS010N-SH27-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 capability ensures interoperability with a wide range of microcontrollers, including those with fixed SPI polarity/phase configurations, without requiring external level-shifting or protocol adaptation.
How does hardware write protection work on AT25FS010N-SH27-T?
Hardware write protection on AT25FS010N-SH27-T is enabled via the WP pin when the WPEN bit (Bit 7 of status register) is set to "1". With WP pulled low and WPEN=1, all writes to the status register-including BP bits and WPEN itself-are inhibited. If WPEN=0, the WP pin is disabled, allowing full status register access even with WP grounded - providing flexible system-level protection design.
What is the endurance rating of AT25FS010N-SH27-T?
The AT25FS010N-SH27-T is rated for 10,000 program/erase cycles per memory sector, based on characterization testing under standard conditions (VCC = 3.0 V, TA = 25°C). This endurance level is sufficient for applications involving infrequent firmware updates or periodic configuration changes, such as industrial controller field upgrades or medical device calibration storage.
Is AT25FS010N-SH27-T compatible with the JEDEC SOIC-8 footprint?
Yes, AT25FS010N-SH27-T uses an 8-lead JEDEC-standard SOIC package (150 mil width, designated "8S1" in ordering codes), fully compatible with IPC-7351B SOIC-8 land patterns. Its pinout matches industry-standard serial flash layouts (CS, SO, WP, GND, VCC, HOLD, SCK, SI), enabling direct replacement in existing designs without PCB revision.
