Product details
Overview
AT25XE041D-SSHN-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 embedded microcontrollers, IoT edge nodes, and industrial controllers.
For engineers reviewing the AT25XE041D-SSHN-T datasheet, AT25XE041D-SSHN-T pinout, AT25XE041D-SSHN-T application, or AT25XE041D-SSHN-T equivalent, key selection criteria include multi-I/O timing compliance, ultra-deep power-down current (5–7 nA), 100,000-cycle endurance, factory-unique ID, and OTP security register support for firmware integrity.
Technical Context
The AT25XE041D-SSHN-T implements a flexible SPI interface with hardware reset (HOLD/RESET pin), JEDEC-standard SFDP, and active status interrupt (RDY/BSY-driven host interrupt). Its architecture integrates a 256-byte SRAM buffer and supports nested erase/program suspend-resume operations across all transfer modes.
It delivers true eXecute-in-Place (XiP) via 0-4-4 command format with no opcode overhead, continuous read mode, and configurable I/O drive strength. Memory protection includes individual block lock, user-definable protected regions, and volatile/non-volatile status registers with lock capability.

Applications
| Firmware Storage in MCU Boot Systems | eXecute-in-Place (XiP) Code Execution |
|---|---|
Use Scenario: Storing bootloader and application firmware for ARM Cortex-M or RISC-V microcontrollers during cold start and OTA updates. IC Role / Device Role / Timing Role: Non-volatile program memory accessed via SPI during boot sequence; supports sequential read and fast page program for delta updates. Use Value: 256-byte page erase enables efficient patching of firmware images without full chip erase; 1.65 V min supply ensures compatibility with low-power brown-out conditions. | Use Scenario: Running real-time control code directly from flash in automotive body controllers or industrial PLCs without RAM copy. IC Role / Device Role / Timing Role: XiP memory mapped via SPI controller with 0-4-4 command format; delivers sub-100 ns effective instruction fetch latency at 133 MHz. Use Value: Eliminates 512 KB RAM footprint and boot time delay; quad I/O bandwidth sustains >400 MB/s sustained read for tight-loop execution. |
| Data Logging in Battery-Powered Sensors | Secure Firmware Identity Binding |
Use Scenario: Recording timestamped sensor readings (temperature, humidity, motion) in smart meters and environmental monitors over multi-year deployments. IC Role / Device Role / Timing Role: Low-power non-volatile storage with ultra-deep power-down (5–7 nA) and fast wake-up; uses page program for incremental writes. Use Value: 100,000-cycle endurance supports >10 years of daily 100-write cycles; 256-byte granularity avoids erasing unrelated log entries. | Use Scenario: Binding cryptographic keys and device-specific identifiers to prevent firmware cloning or unauthorized reprogramming in medical or industrial devices. IC Role / Device Role / Timing Role: Secure storage element using 3×128-byte OTP registers and factory-programmed 128-byte UID; accessed only via locked commands (9Bh/4Bh). Use Value: OTP registers are permanently programmable and irreversibly lockable; UID provides cryptographically verifiable device uniqueness for attestation protocols. |
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), 1.7–3.6 V, 133 MHz quad I/O, but lacks RMW command and active status interrupt. | No hardware interrupt signaling; requires software polling for RDY/BSY, increasing CPU load in real-time systems. | Choose W25Q40EW if cost sensitivity outweighs need for RMW or interrupt-driven status reporting. |
| Micron MT25QL04A | 4 Mbit, 1.7–3.6 V, 133 MHz, supports SFDP and XiP, but no OTP registers or factory UID; UDPD current is 25 nA (vs. 5–7 nA). | Lacks hardware-based device identity and secure key binding; higher UDPD current reduces battery life in ultra-low-power sleep states. | Choose MT25QL04A when SFDP compatibility and broad ecosystem tooling are prioritized over unique ID or sub-10 nA power-down. |
Compared with W25Q40EW and MT25QL04A, AT25XE041D-SSHN-T uniquely combines ultra-low UDPD current (5–7 nA), factory UID, OTP security registers, and Read-Modify-Write functionality-making it optimal for secure, battery-constrained, interrupt-driven embedded applications where deterministic latency and firmware integrity are critical.

This allows host processors to fetch instructions directly from flash with minimal latency, and is fully documented in Section 4.6 and Figure 15–16 of the AT25XE041D-SSHN-T datasheet.
How many times can the AT25XE041D-SSHN-T be programmed and erased?
The AT25XE041D-SSHN-T guarantees 100,000 program/erase cycles per memory sector, with 20-year data retention at temperatures from –40 °C to +85 °C. This endurance is measured per JEDEC JESD22-A117 and validated across all erase granularities (256-byte page to full chip), as specified in Section 7.6 of the AT25XE041D-SSHN-T datasheet.
What security features does the AT25XE041D-SSHN-T provide?
The AT25XE041D-SSHN-T includes a factory-programmed 128-byte unique identifier, three 128-byte One-Time Programmable (OTP) security registers, individual block protection, and status register locking. These features support secure boot, device attestation, and firmware integrity verification, and are implemented per Sections 4.11, 4.8, and 5.32 of the AT25XE041D-SSHN-T datasheet.
What is the ultra-deep power-down (UDPD) current of the AT25XE041D-SSHN-T?
The AT25XE041D-SSHN-T draws only 5–7 nA in Ultra-Deep Power-Down mode (command 79h), making it suitable for decade-long deployments in battery-powered IoT endpoints. This value is measured per Section 7.1 and Table 7 of the AT25XE041D-SSHN-T datasheet under specified VCC and temperature conditions.
