Product details
Overview
AT25DF011-XMHN-B from Renesas Electronics is a 1-Mbit SPI serial Flash memory IC designed for code shadowing and embedded data storage in resource-constrained systems. It operates from 1.65 V to 3.6 V, supports SPI Modes 0/3, delivers 104 MHz max clock frequency, achieves 6 ns clock-to-output delay, and features dual-output read for enhanced throughput - deployed in IoT edge nodes, industrial controllers, and automotive infotainment boot memory.
For engineers reviewing the AT25DF011-XMHN-B datasheet, AT25DF011-XMHN-B pinout, AT25DF011-XMHN-B application, or AT25DF011-XMHN-B equivalent, this page provides verified electrical specs, package mapping to 8-lead SOIC (150-mil), dual-I/O timing behavior, OTP security register configuration, and real-world erase/program performance metrics for production-level design validation.
Technical Context
The AT25DF011-XMHN-B implements a dedicated SPI interface with hardware-controlled write protection via the WP pin and suspend/resume capability via HOLD. Its command set includes standard Read Array (03h), Dual-Output Read (3Bh), Page Erase (81h), and uniform 4-kByte/32-kByte Block Erase (20h/52h), all operating under a single supply without auxiliary voltage rails.
Internally, it uses a segmented memory architecture with 256-byte pages and hierarchical erase blocks (4 kByte and 32 kByte), enabling efficient co-location of firmware code and runtime data. The integrated 128-byte OTP security register contains 64 bytes factory-programmed unique ID and 64 bytes user-programmable space, supporting device serialization and secure key storage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 Mbit (131,072 bytes) - sufficient for bootloader + firmware image in compact MCU-based designs. |
| Supply Voltage Range | 1.65 V to 3.6 V - enables direct interfacing with 1.8 V and 3.3 V logic domains without level shifters. |
| Max Clock Frequency | 104 MHz - supports high-speed read access critical for fast boot and real-time firmware updates. |
| Read Latency (tV) | 6 ns - ensures minimal wait states when fetching instructions from external Flash into RAM. |
| Erase Granularity | 256-byte page / 4-kByte block / 32-kByte block - allows selective firmware patching without full chip erase. |
| Program Endurance | 100,000 cycles at -40 °C to +85 °C - validated for field-upgradable embedded applications with frequent OTA updates. |
| Data Retention | 20 years - guarantees long-term reliability in unattended industrial deployments. |
Pinout & Package
AT25DF011-XMHN-B is packaged in an industry-standard 8-lead SOIC (150-mil) with gull-wing leads, RoHS-compliant, and rated for -40 °C to +85 °C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip Select Input | Active-low enable signal; must transition high-to-low to initiate any command sequence and low-to-high to terminate. |
| SCK | Serial Clock Input | Drives data sampling on rising edge (SI) and output timing on falling edge (SO); supports up to 104 MHz. |
| SI (I/O0) | Serial Input / Dual-Output Data Line | Primary command/address/data input; becomes output during Dual-Output Read (3Bh) to deliver LSB data stream. |
| SO (I/O1) | Serial Output / Dual-Output Data Line | Primary data output; remains active during Dual-Output Read to deliver MSB data stream alongside SI. |
| WP | Hardware Write Protect Input | Low-active pin enabling sector locking; internally pulled high - tie to VCC if unused to prevent spurious writes. |
| HOLD | Communication Suspend Input | Pauses ongoing SPI transfers without deselecting device; requires CS asserted and SCK low to activate. |
| VCC | Power Supply | Single 1.65–3.6 V rail powers all logic and memory functions - no charge pump or VPP required. |
| GND | Ground Reference | System ground return path; decoupling capacitor placement near this pin is critical for noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-Output Read Mode | Enables 2-bit-per-clock data transfer using SI and SO simultaneously, doubling effective read bandwidth over standard SPI. |
| Flexible Erase Architecture | Supports page (256 B), 4-kB block, 32-kB block, and full-chip erase - minimizes wasted space in mixed code/data layouts. |
| OTP Security Register | 128-byte one-time programmable area with 64-byte factory-unique ID and 64-byte user space for ESN or cryptographic keys. |
| Ultra-Low Power States | 200 nA ultra-deep power-down current enables battery-powered devices to retain memory state for years. |
| Hardware Sector Protection | WP pin enables immediate, glitch-immune lock of protected memory regions without software intervention. |

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 max clock, same SOIC-8 package, but lacks dual-output read and OTP register. | Higher capacity for larger firmware images; unsuitable where dual-read throughput or device serialization is required. | Select when memory size >1 Mbit is needed and OTP/dual-read are not design requirements. |
| Micron MT25QL01GBBB8E12-0SIT | 1-Gbit density, quad-SPI interface, 133 MHz clock, SOIC-8 footprint compatible but pinout differs (no HOLD, different WP behavior). | Supports QSPI x4 mode for 4× bandwidth; incompatible pin-for-pin due to missing HOLD and altered protection logic. | Choose for bandwidth-intensive applications needing >1 Mbit; requires PCB redesign and driver adaptation. |
Compared with W25Q80DVSSIG and MT25QL01GBBB8E12-0SIT, the AT25DF011-XMHN-B uniquely balances low-density efficiency, dual-output throughput, hardware write protection, and factory-serialized OTP - making it optimal for cost-sensitive, space-constrained, and security-aware embedded designs where 1 Mbit suffices.

FAQ
What is the maximum operating frequency supported by the AT25DF011-XMHN-B?
The AT25DF011-XMHN-B supports a maximum operating frequency of 104 MHz for read, program, and erase commands. This applies to standard Read Array (03h), Dual-Output Read (3Bh), Page Erase (81h), and Block Erase (20h/52h) operations. At this speed, the device achieves a clock-to-output delay (tV) of 6 ns, enabling high-throughput data access in time-critical embedded systems.
Does the AT25DF011-XMHN-B support dual-output read, and how is it enabled?
Yes, the AT25DF011-XMHN-B supports Dual-Output Read using opcode 3Bh. During this mode, both the SI (I/O0) and SO (I/O1) pins function as outputs, delivering two bits per clock cycle on the falling edge of SCK. No configuration register setting is required - activation is command-driven, and the SI pin automatically transitions from input to output upon receipt of the 3Bh command.
What package type is used for the AT25DF011-XMHN-B, and what are its mechanical dimensions?
The AT25DF011-XMHN-B uses an 8-lead SOIC (Small Outline Integrated Circuit) package with 150-mil body width. Its dimensions are 5.0 mm × 4.0 mm × 1.75 mm (L × W × H), compliant with JEDEC MS-012 standards. This package is pin-compatible with industry-standard SOIC-8 footprints and supports reflow soldering per J-STD-020.
How does the hardware write protection (WP) function work on the AT25DF011-XMHN-B?
The WP pin on the AT25DF011-XMHN-B is a low-active input that enables hardware-controlled locking of protected memory sectors. When WP is driven low, it prevents write/erase commands from modifying protected blocks regardless of software status register settings. The pin is internally pulled high, so it may be left floating if unused - though Renesas recommends tying it to VCC for robustness against noise-induced writes.
What is the purpose and structure of the OTP security register in the AT25DF011-XMHN-B?
The AT25DF011-XMHN-B includes a 128-byte One-Time Programmable (OTP) security register. Of these, 64 bytes are factory-programmed with a unique device identifier (UID), and the remaining 64 bytes are user-programmable once. This register supports secure device serialization, electronic serial number (ESN) storage, and locked key provisioning - accessed via dedicated Program OTP (06h + 3Bh) and Read OTP (06h + 3Ch) commands.
