Product details
Overview
AT25DN011-SSHF-T from Renesas Electronics is a 1-Mbit SPI serial flash memory IC designed for code shadowing and data storage in embedded systems. It operates from 2.3 V to 3.6 V, supports SPI Modes 0/3 and Dual-Output Read, delivers 104 MHz max clock frequency, and achieves 6 ns clock-to-output timing - enabling fast boot and firmware update in resource-constrained IoT edge nodes and industrial controllers.
For engineers reviewing the AT25DN011-SSHF-T datasheet, AT25DN011-SSHF-T pinout, AT25DN011-SSHF-T application, or AT25DN011-SSHF-T equivalent, key selection criteria include dual-read throughput, ultra-low deep power-down current (350 nA), flexible erase granularity (256-byte page / 4-kB & 32-kB blocks), OTP security register support, and industrial temperature compliance (-40°C to +85°C).
Technical Context
The AT25DN011-SSHF-T implements a dedicated SPI interface with hardware-controlled write protection via WP pin and suspend/resume capability via HOLD pin. Its command set includes standardized opcodes (e.g., 02h for byte/page program, 3Bh for Dual-Output Read, 81h for page erase) and supports JEDEC-compliant Manufacturer/Device ID read (9Fh).
Internally, it features a segmented memory architecture with uniform 4-kB and 32-kB erase blocks plus 256-byte programmable pages, optimized to minimize wasted space in mixed code+data layouts. The integrated 128-byte OTP security register enables device serialization and ESN storage without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 Mbit (131,072 bytes) - sufficient for bootloader, firmware image, and configuration data in compact MCU-based designs. |
| Supply Voltage | 2.3 V – 3.6 V - compatible with single-supply 3.3 V systems and battery-powered devices down to 2.3 V. |
| Max Clock Frequency | 104 MHz - enables high-speed read access and reduces boot time in real-time applications. |
| Read Timing (tV) | 6 ns - ensures minimal latency between clock edge and valid output data, critical for deterministic timing in control loops. |
| Erase Granularity | 256-byte page / 4-kB block / 32-kB block - allows precise updates of firmware segments or logging buffers without full-chip erase. |
| Power-Down Current | 350 nA (ultra-deep) / 7.5 µA (deep) - extends battery life in always-on sensor nodes and wearables. |
| Endurance & Retention | 100,000 program/erase cycles / 20 years data retention - meets long-life requirements for industrial field equipment. |
Pinout & Package
AT25DN011-SSHF-T is packaged in an 8-lead SOIC (150-mil) with standard JEDEC footprint and pinout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip Select | Active-low enable signal; must be asserted before opcode transmission and held low during command execution. |
| SCK | Serial Clock | Master-generated clock; rising edge latches input (SI), falling edge clocks output (SO/SI in dual mode). |
| SI (I/O0) | Serial Input / Dual-Output Data 0 | Input for commands/addresses/data; becomes output (I/O0) during Dual-Output Read to double throughput. |
| SO (I/O1) | Serial Output / Dual-Output Data 1 | Primary output for standard reads; remains output (I/O1) during Dual-Output Read for concurrent 2-bit transfer. |
| WP | Write Protect | Hardware lock control; low state enables status register write and sector protection - prevents accidental firmware overwrite. |
| HOLD | Communication Suspend | Pauses ongoing SPI transfer without deselecting device; maintains internal state during host interrupt handling. |
| VCC | Power Supply | 2.3–3.6 V supply input; powers all logic and memory array; no separate programming voltage required. |
| GND | Ground Reference | System ground return path; must be low-impedance to ensure stable read/write margins and noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-Output Read (3Bh) | Two bits per SCK cycle - doubles effective read bandwidth vs. standard SPI, accelerating firmware load and OTA updates. |
| Flexible Erase Architecture | Page (256 B), 4-kB, 32-kB, and full-chip erase - eliminates need for external EEPROM or FRAM in hybrid code+data storage. |
| 128-byte OTP Security Register | One-time programmable storage for unique device IDs, cryptographic keys, or calibration data - enhances system-level security and traceability. |
| Ultra-Deep Power-Down Mode | 350 nA typical current - enables multi-year operation on coin-cell batteries in remote monitoring sensors. |
| Industrial Temperature Range | -40°C to +85°C - qualified for deployment in automotive cabin modules, factory automation PLCs, and outdoor infrastructure. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Winbond W25Q80DVSSIG | 8-Mbit density, 104 MHz, same SOIC-8 package, but lacks Dual-Output Read and OTP register. | Higher capacity for larger firmware images; unsuitable where dual-read throughput or secure serialization is required. | Select when memory size >1 Mbit is needed and security features are handled externally. |
| Macronix MX25L1006EM1I-12G | 1-Mbit, 85 MHz max clock, SOIC-8, supports standard SPI read only (no dual-output), 1 µA deep power-down. | Lower performance and higher standby current; suitable for cost-sensitive, non-latency-critical applications. | Choose for legacy designs requiring pin-compatible replacement with relaxed timing and power budgets. |
Compared with W25Q80DVSSIG and MX25L1006EM1I-12G, the AT25DN011-SSHF-T uniquely combines 104 MHz dual-read speed, 350 nA ultra-deep power-down, and integrated OTP security - making it optimal for next-generation ultra-low-power, secure, and latency-sensitive embedded systems.

FAQ
What is the maximum operating frequency supported by the AT25DN011-SSHF-T?
The AT25DN011-SSHF-T supports a maximum operating frequency of 104 MHz for all commands including Read Array (0Bh), Dual-Output Read (3Bh), Page Erase (81h), and Byte/Page Program (02h). This enables high-throughput data access and rapid firmware loading in time-critical applications. The 6 ns clock-to-output timing further ensures deterministic read performance at this speed.
Does the AT25DN011-SSHF-T support Dual-Output Read, and how does it improve system performance?
Yes, the AT25DN011-SSHF-T supports Dual-Output Read using opcode 3Bh, where both SI and SO pins output data concurrently on each SCK falling edge. This doubles effective read bandwidth compared to standard SPI, reducing firmware load time by up to 50% - a critical advantage in boot-critical applications like industrial gateways and medical devices where startup latency must be minimized.
What erase options are available on the AT25DN011-SSHF-T, and why is flexible granularity important?
The AT25DN011-SSHF-T offers four erase options: 256-byte page erase (81h), 4-kB block erase (20h), 32-kB block erase (52h), and full chip erase (60h/C7h). Flexible granularity minimizes wasted memory space when updating small firmware modules or logging buffers - avoiding the inefficiency of large-block-only flash, which improves usable density and extends endurance in mixed code+data applications.
How does the 128-byte OTP security register in the AT25DN011-SSHF-T enhance system security?
The AT25DN011-SSHF-T integrates a 128-byte One-Time Programmable (OTP) security register accessible via opcodes 9Bh (program) and 77h (read). Once programmed, contents cannot be altered - enabling secure storage of device-unique identifiers, cryptographic keys, or calibration constants. This eliminates reliance on external secure elements and simplifies compliance with standards like IEC 62443 for industrial IoT identity assurance.
What power-saving modes does the AT25DN011-SSHF-T offer, and what are their typical current draws?
The AT25DN011-SSHF-T provides two ultra-low-power states: Deep Power-Down (B9h) with 7.5 µA typical current, and Ultra-Deep Power-Down (79h) with 350 nA typical current. Both modes retain memory contents and resume instantly upon wake command (ABh or chip-select toggle). These modes extend battery life in always-on sensors and portable diagnostics tools far beyond conventional serial flash alternatives.
