Renesas AT25DF011-XMHN-T

Overview

AT25DF011-XMHN-T from Renesas Electronics is a 1-Mbit SPI serial Flash memory IC designed for code shadowing and embedded data storage in resource-constrained systems. It operates from 1.65 V to 3.6 V, supports SPI Modes 0/3 and Dual-Output Read, delivers 104 MHz max clock frequency, and features 6 ns clock-to-output timing - enabling fast boot and firmware update in IoT edge nodes and portable medical devices.

For engineers reviewing the AT25DF011-XMHN-T datasheet, AT25DF011-XMHN-T pinout, AT25DF011-XMHN-T application, or AT25DF011-XMHN-T equivalent, key selection criteria include its 256-byte page erase granularity, OTP security register with factory-unique ID, ultra-deep power-down current (200 nA), and support for -40 °C to +125 °C operation at ≥1.7 V.

Technical Context

The AT25DF011-XMHN-T implements a flexible hierarchical erase architecture with three granularities: 256-byte pages, uniform 4-kByte blocks, and uniform 32-kByte blocks - optimized to minimize wasted space in mixed code+data layouts. Its Dual-Output Read mode uses both SI and SO pins as outputs, doubling read throughput versus standard SPI Read Array (03h) at up to 50 MHz.

Command execution is controlled via an 8-bit opcode followed by address/data bytes (MSB-first), with hardware write protection enabled via the active-low WP pin and optional software locking via Status Register bits. The device integrates a 128-byte OTP security register (64 bytes factory-programmed unique ID + 64 bytes user-programmable) and supports JEDEC-standard Manufacturer/Device ID reads.

Key Specifications

FAQ

What is the maximum operating frequency supported by the AT25DF011-XMHN-T?

The AT25DF011-XMHN-T supports a maximum operating frequency of 104 MHz for most commands including Page Erase, Block Erase, and Chip Erase. For standard Read Array (03h), the limit is 33 MHz; Dual-Output Read (3Bh) operates up to 50 MHz. These values are specified across the full temperature range of –40 °C to +85 °C and –40 °C to +125 °C per the official Renesas DS-AT25DF011-032 Rev. J datasheet.

Does the AT25DF011-XMHN-T support Dual-Output Read, and how does it improve performance?

Yes, the AT25DF011-XMHN-T supports Dual-Output Read using the 3Bh opcode, which configures both SI (I/O0) and SO (I/O1) pins as outputs to deliver two bits per clock cycle. This doubles effective read throughput compared to standard SPI Read Array (03h) at the same clock rate - reducing firmware load time in boot-critical applications. The feature is fully documented in Section 5.1 and Figure 9 of the AT25DF011-XMHN-T datasheet.

What is the purpose and structure of the OTP Security Register in the AT25DF011-XMHN-T?

The AT25DF011-XMHN-T includes a 128-byte One-Time Programmable (OTP) Security Register: 64 bytes are factory-programmed with a unique device identifier, and 64 bytes are user-programmable for secure key storage or system-level ESN. Once written, OTP bytes cannot be altered - providing hardware-enforced immutability for cryptographic keys and device authentication. Programming is performed via the 4Bh command as defined in Section 10.1 of the AT25DF011-XMHN-T datasheet.

How does the AT25DF011-XMHN-T handle power-down modes, and what are their current draw specifications?

The AT25DF011-XMHN-T offers two ultra-low-power states: Deep Power-Down (5 µA typical) and Ultra-Deep Power-Down (200 nA typical). Both retain all register contents and require specific commands (B9h and 79h respectively) to enter, and dedicated wake-up sequences (ABh and 79h + CS toggle) to exit. These modes are validated across –40 °C to +125 °C and enable multi-year battery operation in always-on edge sensors - details are in Sections 12.3–12.6 of the AT25DF011-XMHN-T datasheet.

What package type is used for the AT25DF011-XMHN-T, and what are its mechanical dimensions?

The AT25DF011-XMHN-T uses an 8-lead TSSOP (Thin Shrink Small Outline Package) with gull-wing leads, measuring 4.4 mm × 3.0 mm × 1.2 mm and 0.65 mm lead pitch. This package is explicitly listed in the Ordering Information table (Section 16) and illustrated in Figure 2 of the AT25DF011-XMHN-T datasheet. It provides better thermal dissipation and smaller footprint than SOIC while maintaining compatibility with standard SMT reflow processes.
