Product details
Overview
AT25XE041B-XMHN-T from Renesas Electronics is a 4-Mbit serial SPI Flash memory IC supporting Dual-I/O operation, 85 MHz max clock frequency, 1.65–3.6 V single-supply operation across –40°C to +85°C, and flexible erase architecture (256-byte page, 4/32/64-kByte blocks, full chip). It serves as nonvolatile code and data storage in microcontroller boot systems and firmware update modules.
For engineers reviewing the AT25XE041B-XMHN-T datasheet, AT25XE041B-XMHN-T pinout, AT25XE041B-XMHN-T application, or AT25XE041B-XMHN-T equivalent, key selection considerations include Dual-I/O read throughput, ultra-deep power-down current (200 nA), OTP security register usability, sector protection via WP pin, and compatibility with SPI Modes 0 and 3 in space-constrained industrial and consumer designs.
Technical Context
The AT25XE041B-XMHN-T implements a serial peripheral interface with hardware-controlled write protection via the WP pin and software-managed sector locking. Its memory array is partitioned into uniform 4-kByte blocks (128 total), 32-kByte blocks (16), and 64-kByte blocks (8), enabling efficient co-location of code and data without cross-erase interference.
Dual-I/O Read mode delivers two bits per SCK falling edge using SI (I/O0) and SO (I/O1), doubling effective read bandwidth versus standard SPI. The device supports sequential program mode with status polling and includes an active status interrupt for asynchronous operation monitoring.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 4 Mbit (512 kByte) organized as 65,536 × 8-bit; enables compact firmware storage without external memory expansion. |
| Max Clock Frequency | 85 MHz; supports high-speed instruction fetch and OTA update streaming with tV = 6 ns clock-to-output delay. |
| Erase Granularity | 256-byte page, 4/32/64-kByte uniform blocks, and full-chip erase; allows precise firmware patching and data logging without erasing unrelated sectors. |
| Power Consumption | 200 nA ultra-deep power-down current (typical); extends battery life in always-on IoT sensors and wearables during idle periods. |
| OTP Security Register | 128-byte register with 64-byte factory-unique ID and 64-byte user-programmable space; supports secure device authentication and ESN binding. |
| Operating Voltage | 1.65 V to 3.6 V over –40°C to +85°C; interoperates directly with 1.8 V and 3.3 V MCUs without level-shifting circuitry. |

Pinout & Package
AT25XE041B-XMHN-T uses an 8-pin Ultra Thin DFN package measuring 2 mm × 3 mm × 0.6 mm (JEDEC MO-252), optimized for space-constrained portable and wearable electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip Select | Active-low enable signal; initiates command latching on high-to-low transition and terminates operations on low-to-high transition. |
| SCK | Serial Clock | Master-generated clock; commands, addresses, and input data latched on rising edge; output data clocked on falling edge. |
| SI (I/O0) | Serial Input / Dual-I/O Data 0 | Primary data-in path for commands/addresses; becomes I/O0 output during Dual-I/O Read to deliver LSB of dual-bit data stream. |
| SO (I/O1) | Serial Output / Dual-I/O Data 1 | Primary data-out path; remains I/O1 output during Dual-I/O Read to deliver MSB of dual-bit data stream synchronized to SCK falling edge. |
| WP | Write Protect | Hardware lock control; low assertion enables sector protection bypass; internally pulled-high, can be left floating if unused. |
| HOLD | Communication Hold | Pauses ongoing SPI transfer without deselecting device; requires CS asserted and SCK low to activate; internally pulled-high. |
| VCC | Power Supply | Single 1.65–3.6 V supply; powers all internal logic and memory array; no auxiliary voltage required for programming/erasing. |
| GND | Ground Reference | System ground return path; must be connected to minimize noise coupling and ensure stable read/write margins. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-I/O Read Mode | Delivers 2× read bandwidth vs. standard SPI by clocking two bits per SCK falling edge using SI and SO as complementary outputs. |
| Flexible Erase Architecture | Supports 256-byte page erase for fine-grained data updates and multiple uniform block sizes (4/32/64-kByte) to match code module boundaries. |
| Hardware + Software Protection | WP pin enables hardware locking of protected sectors; software commands allow granular sector protect/unprotect and global lock control. |
| Ultra-Low Power States | 200 nA ultra-deep power-down and 4.5 µA deep power-down modes reduce system standby power in battery-powered applications. |
| OTP Security Register | Factory-programmed 64-byte unique ID enables device serialization; user-programmable 64-byte region stores cryptographic keys or calibration data. |

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 W25Q40EW | 4 Mbit density, 1.7–1.95 V min supply, no OTP register, 100 µA deep power-down (vs. 4.5 µA) | Lacks factory-unique ID and ultra-low-power states; suited for cost-sensitive, non-security-critical consumer apps | Choose when OTP and sub-5 µA deep power-down are not required and 1.7 V minimum supply suffices. |
| Micron MT25QL04A | 4 Mbit density, 1.7–2.0 V min supply, Quad-I/O support (not Dual-I/O only), 25 µA deep power-down | Offers higher bandwidth via Quad-I/O but consumes more standby current; no OTP security register | Prefer when system design supports Quad-SPI interface and higher active power is acceptable for faster bulk reads. |
Compared with W25Q40EW and MT25QL04A, the AT25XE041B-XMHN-T uniquely combines ultra-deep power-down (200 nA), factory-programmed unique ID, and Dual-I/O read at 1.65 V minimum supply-making it optimal for secure, battery-constrained edge devices requiring guaranteed low-power operation and device identity.

FAQ
What is the minimum operating voltage for the AT25XE041B-XMHN-T?
The AT25XE041B-XMHN-T operates down to 1.65 V across the full industrial temperature range (–40°C to +85°C), enabling direct interfacing with 1.8 V microcontrollers without level shifters. At extended temperature (–40°C to +125°C), the minimum supply rises to 1.7 V. This specification is verified in Table 16 (DC Characteristics) of the official Renesas datasheet DS-AT25XE041B-062.
Does the AT25XE041B-XMHN-T support Quad-I/O or only Dual-I/O?
The AT25XE041B-XMHN-T supports Serial Peripheral Interface (SPI) Modes 0 and 3 with Dual-I/O Read capability only-it does not support Quad-I/O. Dual-I/O uses SI (I/O0) and SO (I/O1) to output two bits per SCK falling edge, doubling read throughput versus standard SPI. This is explicitly defined in the "Features" section and Section 5.1 of the AT25XE041B datasheet.
How is the 128-byte OTP security register structured in the AT25XE041B-XMHN-T?
The AT25XE041B-XMHN-T's OTP security register is split into two 64-byte segments: the first 64 bytes are factory-programmed with a unique device identifier (e.g., serial number or ESN), and the second 64 bytes are user-programmable for keys, certificates, or calibration data. Programming is one-time only and irreversible, as confirmed in Section 10 and Table 9 of the datasheet.
What package type does the AT25XE041B-XMHN-T use, and what are its dimensions?
The AT25XE041B-XMHN-T uses an 8-pad Ultra Thin DFN package measuring 2.0 mm × 3.0 mm × 0.6 mm (JEDEC MO-252), specified in Section 17.3 of the datasheet. This compact footprint supports high-density PCB layouts in wearables and portable medical devices, and the part is RoHS-compliant and halogen-free.
Can the AT25XE041B-XMHN-T be used in automotive applications requiring AEC-Q100 qualification?
No-the AT25XE041B-XMHN-T is rated for the full industrial temperature range (–40°C to +85°C or +125°C) but is not AEC-Q100 qualified. It is intended for industrial, consumer, and IoT applications. For automotive-grade alternatives, Renesas offers the AT25DFxxA-Q series, which undergoes AEC-Q100 stress testing and supports extended temperature ranges up to +125°C with automotive qualification.
