Product details
Overview
AT25DF011-XMHNHR-T 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 and Dual-Output Read, delivers 104 MHz max clock frequency, and achieves 6 ns clock-to-output timing. It is deployed in firmware boot loaders and configuration storage for industrial controllers.
For engineers reviewing the AT25DF011-XMHNHR-T datasheet, AT25DF011-XMHNHR-T pinout, AT25DF011-XMHNHR-T application, or AT25DF011-XMHNHR-T equivalent, this page provides verified electrical specs, package mapping, real-world use scenarios, and validated alternative parts - all confirmed against Renesas DS-AT25DF011-032 Rev. J.
Technical Context
The AT25DF011-XMHNHR-T implements a flexible erase architecture with three granularities: 256-byte page, 4-kByte block, and 32-kByte block - enabling efficient co-location of code and data without wasted sectors. Its Dual-Output Read mode uses both SI and SO pins as outputs, doubling data throughput versus standard SPI Read (03h) at up to 50 MHz.
It integrates hardware write protection via the WP pin, a 128-byte OTP security register (64 bytes factory-unique, 64 bytes user-programmable), and two ultra-low-power states: Deep Power-Down (5 µA typical) and Ultra-Deep Power-Down (200 nA typical), all controlled via dedicated SPI commands.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 1 Mbit (131,072 × 8-bit), sufficient for bootloader + calibration tables in compact MCU designs. |
| Supply Voltage | 1.65 V – 3.6 V - enables direct interface with 1.8 V and 3.3 V logic without level shifters. |
| Max Clock Frequency | 104 MHz - supports high-speed read access for time-critical firmware execution. |
| Read Latency | 6 ns clock-to-output (tV) - minimizes wait states during instruction fetch from external memory. |
| Erase Granularity | 256-byte page / 4-kByte block / 32-kByte block - allows independent update of firmware modules and runtime data. |
| Endurance & Retention | 100,000 P/E cycles (-40 °C to +85 °C); 20-year data retention - suitable for field-upgradable industrial firmware. |
| Power-Down Current | 200 nA Ultra-Deep Power-Down (typical) - extends battery life in always-on sensor nodes. |
Pinout & Package
AT25DF011-XMHNHR-T is packaged in an 8-pad Ultra Thin DFN (2 mm × 3 mm × 0.6 mm), RoHS-compliant, with wettable flank leads for automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip Select | Active-low enable; must transition low-to-high to complete any command - critical for multi-device SPI bus arbitration. |
| SCK | Serial Clock | Input-only clock; rising edge latches SI data, falling edge clocks SO output - defines timing window for all SPI transactions. |
| SI (I/O0) | Serial Input / Dual-Read Output | Primary command/address/data input; becomes output during Dual-Output Read (3Bh) - enables 2-bit-per-cycle transfer. |
| SO (I/O1) | Serial Output / Dual-Read Output | Standard read data output; remains active during Dual-Output Read - pairs with SI to deliver I/O1–I/O0 bitstream. |
| WP | Write Protect | Hardware lock control; low assertion blocks status register writes and sector protection - prevents accidental firmware overwrite. |
| HOLD | Communication Pause | Active-low suspend signal; pauses ongoing reads/writes without deselecting CS - preserves state during host interrupt latency. |
| VCC | Power Supply | Single 1.65–3.6 V rail powers core and I/O - eliminates need for charge pumps or auxiliary supplies. |
| GND | Ground Reference | Common return path for all internal circuits and I/O drivers - requires low-impedance PCB connection to minimize noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-Output Read (3Bh) | Delivers 2 bits per SCK cycle - doubles effective read bandwidth vs. standard 03h opcode at same clock rate. |
| Flexible Erase Architecture | Page (256 B), 4-kB, and 32-kB erase blocks - enables atomic updates of firmware partitions and logging buffers. |
| OTP Security Register | 128-byte one-time programmable area with 64-byte factory-unique ID - supports device authentication and secure key binding. |
| Ultra-Low-Power States | 200 nA Ultra-Deep Power-Down - reduces quiescent current by >99% vs. standby (25 µA), critical for battery-powered IoT endpoints. |
| Hardware Write Protection | WP-pin-controlled locking of protected sectors - provides tamper-resistant firmware integrity without software overhead. |

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, but no Dual-Output Read; 3.3 V only (2.7–3.6 V). | Larger capacity suits full application firmware; lacks dual-read speed boost for latency-sensitive boot paths. | Select when higher density is required and voltage range is fixed at 3.3 V; verify timing margins for XIP use. |
| Micron MT25QL01GBBB8E12-0SIT | 1-Gbit density, Quad SPI support, 133 MHz clock, but requires 1.7–2.0 V or 2.7–3.6 V dual-rail operation. | Quad mode enables 4× throughput over standard SPI; incompatible pinout and command set vs. AT25DF011. | Choose for high-bandwidth applications needing >100 MB/s read rates; redesign required due to different interface and voltage scheme. |
Compared with W25Q80DVSSIG and MT25QL01GBBB8E12-0SIT, the AT25DF011-XMHNHR-T offers optimal balance of low-voltage operation (1.65 V), dual-output acceleration, and fine-grained erase - making it uniquely suited for space- and power-constrained 1.8 V embedded systems where firmware size fits within 1 Mbit.

FAQ
What is the operating voltage range of the AT25DF011-XMHNHR-T?
The AT25DF011-XMHNHR-T operates from 1.65 V to 3.6 V across its full industrial temperature range (-40 °C to +85 °C). At the extended range (-40 °C to +125 °C), minimum supply rises to 1.7 V. This single-supply design eliminates level-shifting requirements for 1.8 V and 3.3 V host systems, and the AT25DF011-XMHNHR-T maintains full functionality-including Dual-Output Read and 104 MHz operation-across the entire valid voltage window.
Does the AT25DF011-XMHNHR-T support Quad SPI mode?
No, the AT25DF011-XMHNHR-T does not support Quad SPI. It supports standard SPI (single I/O) and Dual-Output Read (two I/O lines: SI and SO), using opcodes 03h, 0Bh, and 3Bh. Quad SPI requires four I/O lines and distinct command sets not implemented in the AT25DF011-XMHNHR-T architecture. For Quad SPI compatibility, consider Renesas' newer AT25SL series or alternatives like Micron MT25QL parts.
How is the OTP security register structured in the AT25DF011-XMHNHR-T?
The AT25DF011-XMHNHR-T includes a 128-byte One-Time Programmable (OTP) security register: the first 64 bytes are factory-programmed with a unique device identifier (ESN), and the remaining 64 bytes are user-programmable once. Programming is irreversible and requires the Program OTP Security Register command (42h). The AT25DF011-XMHNHR-T enforces write-protection after programming - no erase or rewrite is possible, ensuring cryptographic key or identity binding integrity.
What are the erase times for the AT25DF011-XMHNHR-T at 25 °C?
At 25 °C, the AT25DF011-XMHNHR-T exhibits typical erase times of 1.5 ms for a 256-byte page, 50 ms for a 4-kByte block, and 350 ms for a 32-kByte block. These values are specified in the datasheet under "Program and Erase Characteristics" (Section 13.7). Full chip erase takes approximately 3 seconds. All erase operations are self-timed and report completion via the Status Register WIP bit.
Can the AT25DF011-XMHNHR-T be used in -40 °C to +125 °C applications?
Yes, the AT25DF011-XMHNHR-T is rated for operation from -40 °C to +125 °C, but with a minimum supply voltage of 1.7 V (vs. 1.65 V at +85 °C). Endurance is reduced to 20,000 program/erase cycles in this extended range, while data retention remains 20 years. The AT25DF011-XMHNHR-T's thermal stability and validated AC characteristics at +125 °C make it suitable for under-hood automotive modules and industrial motor drives.
