Product details
Overview
AT25FF041A-MAHN-T from Renesas Electronics is a 4-Mbit serial flash memory IC supporting SPI, dual-output (1-1-2), quad-output (1-1-4), and quad I/O XiP (1-4-4, 0-4-4) modes with 133 MHz max clock frequency, 1.65 V–3.6 V supply range, and uniform 4/32/64-kB block erase. It enables code storage and execution in space-constrained embedded microcontrollers and IoT edge nodes.
For engineers reviewing the AT25FF041A-MAHN-T datasheet, AT25FF041A-MAHN-T pinout, AT25FF041A-MAHN-T application, or AT25FF041A-MAHN-T equivalent, key selection criteria include multi-I/O bandwidth scalability, ultra-low deep power-down current (7 nA), JEDEC-compliant SFDP support, OTP security register availability, and -40°C to +105°C extended temperature operation.
Technical Context
The AT25FF041A-MAHN-T implements a flexible SPI-compatible command set with hardware reset (JEDEC standard), volatile/non-volatile status registers, and nested program/erase suspend-resume capability. Its memory architecture supports uniform block erases (4/32/64 kB) and full-chip erase, enabling deterministic firmware update timing.
It delivers configurable I/O drive strength, burst wrap addressing for continuous XiP reads, and three 128-byte OTP security registers with lockable programming. The device uses indirect and direct status register access methods and supports both standard and wrap-mode dummy clock configurations across temperature grades.
Key Specifications

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 / /CS | Chip Select | Active-low enable for SPI command/address/data transfers; must be deasserted between operations to prevent bus contention. |
| 2 / DO / IO0 | Data Output / I/O 0 | Primary serial data output in standard/dual mode; bidirectional I/O0 in quad I/O and XiP modes. |
| 3 / /WP | Write Protect | Hardware-enabled write protection for status registers and memory blocks when pulled low; overrides software lock bits. |
| 4 / GND | Ground | Reference return path for all digital and analog circuitry; requires low-impedance connection to system ground plane. |
| 5 / SI / IO1 | Serial Input / I/O 1 | Command/address input in standard mode; bidirectional I/O1 in dual/quad I/O modes; supports address/data multiplexing. |
| 6 / SO / IO2 | Serial Output / I/O 2 | Read data output in standard mode; bidirectional I/O2 in quad I/O/XiP; enables 4-bit parallel data transfer during burst reads. |
| 7 / /HOLD | Hold | Pauses ongoing SPI transfer without resetting internal state; allows host to service higher-priority interrupts mid-operation. |
| 8 / VCC | Power Supply | 1.65 V–3.6 V core and I/O supply; decoupling capacitor (≥100 nF) required within 5 mm of pin for stable high-frequency operation. |

FAQ
What is the operating temperature range supported by the AT25FF041A-MAHN-T?
The AT25FF041A-MAHN-T is rated for operation from -40°C to +105°C, with guaranteed endurance (10k program/erase cycles) and data retention (10 years) across this full industrial-plus range. This specification is validated per the manufacturer's datasheet DS-AT25FF041A-184 Rev. N and makes the AT25FF041A-MAHN-T suitable for under-hood automotive and high-ambient industrial environments where thermal resilience is mandatory.
Does the AT25FF041A-MAHN-T support execute-in-place (XiP) functionality?
Yes, the AT25FF041A-MAHN-T supports true quad I/O XiP operation using 1-4-4 and 0-4-4 protocols, enabling direct instruction fetch by host processors without copying to RAM. This capability is confirmed in Section 5.6 of the official datasheet and requires proper configuration of the status registers and burst wrap settings. The AT25FF041A-MAHN-T delivers deterministic latency and high bandwidth for Cortex-M and RISC-V SoCs implementing XiP boot flows.
How many one-time programmable (OTP) security registers does the AT25FF041A-MAHN-T include?
The AT25FF041A-MAHN-T includes three 128-byte One Time Programmable (OTP) security registers, plus a factory-programmed 128-byte unique identifier. These OTP registers are documented in Sections 1.1 and 7.22–7.23 of the datasheet and support irreversible storage of cryptographic keys, calibration data, or device-specific secrets. Once programmed and locked, their contents cannot be altered-ensuring hardware-rooted trust for secure boot implementations using the AT25FF041A-MAHN-T.
What is the minimum supply voltage required for the AT25FF041A-MAHN-T to operate correctly?
The AT25FF041A-MAHN-T operates across a supply voltage range of 1.65 V to 3.6 V, with full functionality-including all interface modes, erase/program operations, and OTP programming-guaranteed down to 1.65 V. This low-voltage capability is specified in Table 8.2 of the datasheet and enables direct integration into 1.8 V systems without level shifters, distinguishing the AT25FF041A-MAHN-T from higher-voltage-only alternatives like the MX25L4006E.
Is the AT25FF041A-MAHN-T compliant with JEDEC standards for serial flash identification and configuration?
Yes, the AT25FF041A-MAHN-T fully complies with JEDEC standards including hardware reset (JESD22-A102), manufacturer/device ID (90h/9Fh), and Serial Flash Discoverable Parameters (SFDP, command 5Ah). These features allow automatic detection and parameter negotiation by host bootloaders, eliminating hardcoded timing values. The AT25FF041A-MAHN-T's SFDP table supports dynamic configuration of dummy clocks, drive strength, and power modes-verified in Sections 7.36–7.37 and Appendix A of DS-AT25FF041A-184.
