Product details
Overview
AT25XE041D-MAHN-T from Renesas Electronics is a 4-Mbit SPI serial Flash memory IC supporting 1.65 V–3.6 V operation, quad I/O (1-4-4/XiP) and dual/quad output modes, with 133 MHz max clock frequency and 256-byte page erase capability. It serves as non-volatile program storage or XiP code execution memory in resource-constrained embedded systems.
For engineers reviewing the AT25XE041D-MAHN-T datasheet, AT25XE041D-MAHN-T pinout, AT25XE041D-MAHN-T application, or AT25XE041D-MAHN-T equivalent, key selection criteria include multi-I/O timing compatibility, ultra-deep power-down current (5–7 nA), RMW command support for EEPROM emulation, and JEDEC SFDP compliance for automatic configuration.
Technical Context
The AT25XE041D-MAHN-T implements a flexible SPI interface supporting standard (1-1-1), dual-output (1-1-2), quad-output (1-1-4), quad-I/O (1-4-4), and XiP (0-4-4) transfer modes - all configurable via command sequences and status register settings. Its internal architecture integrates a 256-byte SRAM buffer, dedicated I/O interface unit, and 4-Mbit Flash array segmented into 256-byte pages and hierarchical blocks (4/32/64 kB).
It features hardware reset (JEDEC-compliant), active status interrupt (RDY/BSY-driven), and dual-mode protection: individual block lock/unlock (36h/39h) plus user-definable start/end memory region protection. The device supports nested erase/program suspend/resume operations and includes three 128-byte OTP security registers with programmable lock bits.

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 | Same density (4 Mbit), 1.7–2.0 V supply range only; no Ultra-Deep Power-Down (min 0.5 µA DPD); lacks RMW command | Less suitable for sub-1.8 V or ultra-low-power battery systems; requires software emulation for byte-write | Select AT25XE041D-MAHN-T when operating below 1.7 V or requiring <10 nA standby. |
| Micron MT25QL04A | Supports 1.7–2.0 V and 2.7–3.6 V dual ranges; includes SFDP v1.6 but no OTP registers; 100K endurance same | Requires voltage rail switching for mixed-voltage designs; lacks hardware-based security for configuration data | Select AT25XE041D-MAHN-T when OTP-based credential storage and unified 1.65–3.6 V operation are required. |

FAQ
What is the minimum supply voltage supported by the AT25XE041D-MAHN-T?
The AT25XE041D-MAHN-T supports a minimum supply voltage of 1.65 V, enabling reliable operation in single-cell Li-ion, Li-po, or coin-cell battery-powered systems where voltage may dip below 1.8 V during discharge. This specification is verified across the full -40°C to +85°C temperature range and is documented in Section 7.2 of the official datasheet.
Does the AT25XE041D-MAHN-T support Execute-in-Place (XiP) functionality?
Yes, the AT25XE041D-MAHN-T supports XiP via its 0-4-4 command format, which eliminates opcode transmission after initial setup and enables continuous high-speed instruction fetch. This mode requires host controller support for quad I/O and is confirmed in Sections 1 and 4.6 of the AT25XE041D datasheet.
How does the Read-Modify-Write (RMW) command work in the AT25XE041D-MAHN-T?
The AT25XE041D-MAHN-T implements RMW via command 0Ah, allowing atomic byte-level updates without external read-erase-program sequences. Internally, it reads a 256-byte page into its SRAM buffer, modifies the target byte, erases the page, and rewrites - all in one command, reducing wear and latency versus discrete operations.
What package type is used for the AT25XE041D-MAHN-T?
The AT25XE041D-MAHN-T uses an 8-pad DFN package measuring 2 mm × 3 mm × 0.6 mm with wettable flank leads, as specified in Ordering Code MAHN-T and detailed in Section 9.3 of the datasheet. This package is RoHS-compliant, halogen-free, and optimized for automated optical inspection and high-density PCB layouts.
Can the AT25XE041D-MAHN-T be used in systems requiring hardware reset compliance?
Yes, the AT25XE041D-MAHN-T implements JEDEC-standard hardware reset via the HOLD/RESET pin (pin 5), supporting both asynchronous reset assertion and synchronized release per JEDEC JESD22-A102. This feature is validated in Section 4.12 and Figure 22 of the AT25XE041D datasheet.
