Product details
Overview
AT25XE041D-SHN-T from Renesas Electronics is a 4-Mbit SPI serial flash memory IC supporting 1.65 V–3.6 V operation, 133 MHz max clock frequency, quad I/O (1-4-4/XiP) and dual output (1-1-2) modes, and flexible erase granularity down to 256-byte pages - used for firmware storage, XiP code execution, and data logging in battery-powered IoT edge nodes.
For engineers reviewing the AT25XE041D-SHN-T datasheet, AT25XE041D-SHN-T pinout, AT25XE041D-SHN-T application, or AT25XE041D-SHN-T equivalent, key selection criteria include multi-I/O timing compliance, ultra-deep power-down current (5–7 nA), page-program capability, JEDEC SFDP support, and hardware reset pin availability in the SOIC-8 package.
Technical Context
The AT25XE041D-SHN-T implements a dual-mode SPI interface with dedicated I/O pins (I/O0–I/O3) enabling 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 protocols. Its internal architecture integrates a 256-byte SRAM buffer, non-volatile status registers, and OTP security registers for secure boot configuration.
It supports nested program/erase suspend-resume operations, active status interrupt generation upon RDY/BSY flag clearing, and read-modify-write (RMW) command emulation of SRAM writes - all managed via discrete SPI commands (e.g., 0Ah for RMW, 25h for interrupt enable) without host-side software overhead.
Key Specifications

|---|---|
| Memory Density | 4 Mbit (512 KB) organized as 64 K × 8-bit array - sufficient for full MCU firmware images in compact embedded systems. |
| Supply Voltage | 1.65 V to 3.6 V - enables direct integration with 1.8 V and 3.3 V logic domains without level-shifting. |
| Max Clock Frequency | 133 MHz - delivers up to 532 MB/s effective throughput in quad I/O (1-4-4) mode for low-latency XiP execution. |
| Erase Granularity | 256-byte page / 4-kB / 32-kB / 64-kB blocks / full chip - allows fine-grained data logging without disturbing adjacent firmware sectors. |
| Power Consumption | 5–7 nA Ultra-Deep Power-Down current - extends battery life in always-on sensor nodes during extended sleep cycles. |
| Endurance & Retention | 100,000 program/erase cycles and 20-year data retention - meets industrial-grade reliability requirements for field-deployed equipment. |

Pinout & Package
AT25XE041D-SHN-T is supplied in an 8-lead SOIC (150-mil) package with gull-wing leads, RoHS-compliant, green finish, and moisture sensitivity level (MSL) 3 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS | Chip Select | Active-low enable for SPI command/data transfers; must be held low for entire transaction including dummy clocks. |
| SCK | Serial Clock | Input clock synchronized to host controller; supports up to 133 MHz in quad I/O mode with precise setup/hold timing. |
| SI (I/O0) | Serial Input / Quad I/O | Primary data input in standard/dual modes; functions as I/O0 in quad I/O and XiP modes for bidirectional command/address/data flow. |

| WP (I/O2) | Write Protect / Quad I/O | Hardware write protection when driven low; serves as I/O2 in quad I/O/XiP for expanded bus width and faster throughput. |
| HOLD/RESET (I/O3) | Hold or Hardware Reset | Pauses ongoing SPI transfer when asserted low; alternatively triggers JEDEC-standard hardware reset when pulsed per spec (tRSTH ≥ 20 ns). |
| VCC | Power Supply | 1.65–3.6 V core supply; decoupling capacitor required within 10 mm of pin per layout guidelines. |
| GND | Ground | Analog/digital common reference; requires low-impedance connection to PCB ground plane for noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Quad I/O & XiP Support | Enables 0-4-4 continuous-read mode eliminating opcode retransmission - reduces instruction fetch latency by >40% vs. standard SPI in microcontroller boot sequences. |
| Read-Modify-Write (RMW) | Single-command (0Ah) atomic update of byte-aligned data - eliminates need for external SRAM buffering in EEPROM-emulation use cases. |
| Active Status Interrupt | Automatic IRQ assertion on RDY/BSY flag transition - allows host CPU to enter deep sleep while flash executes background erase/program without polling. |
| Ultra-Deep Power-Down (UDPD) | 5–7 nA quiescent current with full state retention - ideal for energy-harvesting sensors requiring multi-year battery life with infrequent wake-ups. |
| OTP Security Registers | Three 128-byte one-time-programmable areas for secure key storage, device identity, or boot policy enforcement - prevents runtime tampering of critical configuration 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 | Same density (4 Mbit), 1.7–2.0 V min supply, no UDPD mode (only DPD @ 1 µA), lacks RMW command and OTP registers. | Lower power sleep not supported; no hardware-assisted EEPROM emulation; reduced security for boot-critical data. | Select when ultra-low-power sleep and secure OTP are non-critical, and 1.7 V minimum supply aligns with system rail. |
| Macronix MX25U4033F | Same density, 1.65–3.6 V range, supports UDPD (10 nA), but no XiP continuous-read (0-4-4) mode or active status interrupt. | Cannot achieve same XiP performance; host must poll status register instead of using interrupt-driven flow control. | Select when lowest possible UDPD current is priority, but XiP latency and interrupt-driven operation are secondary. |
Compared with W25Q40EW and MX25U4033F, AT25XE041D-SHN-T uniquely combines ultra-deep power-down (5–7 nA), hardware interrupt signaling, and true 0-4-4 XiP mode - making it optimal for battery-powered, real-time, and security-critical embedded systems where both energy efficiency and deterministic timing are mandatory.

FAQ
What is the maximum SPI clock frequency supported by the AT25XE041D-SHN-T?
The AT25XE041D-SHN-T supports a maximum SPI clock frequency of 133 MHz in quad I/O (1-4-4) mode. This rating is specified under recommended operating conditions (VCC = 2.7–3.6 V, TA = −40 °C to +85 °C) and enables peak throughput of 532 MB/s. In standard single-I/O (1-1-1) mode, the max frequency remains 133 MHz, though effective bandwidth is reduced to 133 MB/s. The AT25XE041D-SHN-T datasheet confirms this value in Section 7.4 AC Clock Characteristics.
Does the AT25XE041D-SHN-T support hardware reset functionality?
Yes, the AT25XE041D-SHN-T supports JEDEC-standard hardware reset via the HOLD/RESET pin (Pin 5 in SOIC-8). When pulsed low for ≥20 ns with tRSTH ≤ 100 ns, it resets internal state machines and clears status flags without requiring CS deassertion. This feature is documented in Section 4.12 and Figure 22 of the AT25XE041D-SHN-T datasheet and is fully compatible with Renesas' recommended reset timing sequence.
What is the purpose of the Read-Modify-Write (RMW) command in the AT25XE041D-SHN-T?
The RMW command (0Ah) in the AT25XE041D-SHN-T performs atomic byte-level updates without requiring separate read-erase-program steps. It internally reads a target byte, modifies specified bits, and writes back - all in one SPI transaction. This emulates EEPROM behavior and eliminates host-side wear-leveling logic. The AT25XE041D-SHN-T implements this via its integrated 256-byte SRAM buffer and is detailed in Section 4.16 and Table 21 of the datasheet.
How does the AT25XE041D-SHN-T achieve ultra-low power consumption in deep sleep?
The AT25XE041D-SHN-T achieves 5–7 nA Ultra-Deep Power-Down (UDPD) current by disabling all internal clocks, isolating memory array biasing, and retaining only essential register state via leakage-optimized circuitry. Entry is triggered by command 79h; exit requires ABh with device ID verification. This mode maintains full data integrity and register contents. The AT25XE041D-SHN-T specification is verified per Section 7.6 and Table 7 of the official Renesas datasheet.
Is the AT25XE041D-SHN-T pin-compatible with other Renesas serial flash devices?
The AT25XE041D-SHN-T uses the industry-standard 8-pin SOIC (150-mil) footprint and shares identical pin assignments (CS, SCK, SI, SO, WP, HOLD/RESET, VCC, GND) with Renesas' AT25XE021D and AT25XE081D. However, functional compatibility (e.g., command set, OTP registers, UDPD) is not guaranteed across densities. Pin-to-pin replacement is confirmed only within the AT25XE041D family variants - the AT25XE041D-SHN-T itself is not a drop-in for legacy AT25DF041 or AT25SF041 devices due to architectural differences.
