Renesas AT25DN011-MAHFGP-Y

Overview

AT25DN011-MAHFGP-Y 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 2.3 V to 3.6 V, supports SPI Modes 0/3 and Dual-Output Read, delivers 104 MHz max clock frequency, and achieves 6 ns clock-to-output timing - enabling high-speed boot code execution in industrial controllers and IoT edge nodes.

For engineers reviewing the AT25DN011-MAHFGP-Y datasheet, AT25DN011-MAHFGP-Y pinout, AT25DN011-MAHFGP-Y application, or AT25DN011-MAHFGP-Y equivalent, key selection criteria include dual-output read throughput, ultra-deep power-down current (350 nA), flexible erase granularity (256-byte page / 4-kB & 32-kB blocks), OTP security register support, and industrial temperature compliance (-40°C to +85°C).

Technical Context

The AT25DN011-MAHFGP-Y implements a dedicated SPI interface with hardware-controlled write protection via the WP pin and suspend/resume capability via HOLD. Its command set includes standardized opcodes (e.g., 02h for byte/page program, 3Bh for Dual-Output Read, 81h for page erase) and supports JEDEC-compliant Manufacturer/Device ID reads (9Fh).

Internally, it features a segmented memory architecture with uniform 4-kB and 32-kB erase blocks plus 256-byte programmable pages, enabling efficient co-location of firmware code and runtime data without cross-contamination. The integrated 128-byte OTP security register provides immutable device serialization and key storage independent of main array operations.

FAQ

What is the maximum SPI clock frequency supported by the AT25DN011-MAHFGP-Y?

The AT25DN011-MAHFGP-Y supports up to 104 MHz for most commands including Page Erase, Block Erase, Chip Erase, and Byte/Page Program. For standard Read Array (03h), the limit is 33 MHz; for Dual-Output Read (3Bh), it is 50 MHz. These differentiated ratings reflect internal timing constraints specific to each command's data path and latch setup/hold requirements - all guaranteed across the full industrial temperature range.

Does the AT25DN011-MAHFGP-Y support hardware write protection independent of software configuration?

Yes, the AT25DN011-MAHFGP-Y supports hardware write protection via the dedicated WP pin. When pulled low, the WP pin locks protected sectors regardless of the status register's BP bits or software write-enable state. This provides fail-safe protection against accidental writes during power transients or firmware faults - a critical feature for bootloader and security-critical regions stored in the AT25DN011-MAHFGP-Y.

How does the Dual-Output Read mode function on the AT25DN011-MAHFGP-Y?

In Dual-Output Read mode (opcode 3Bh), both the SI and SO pins become outputs: SI (I/O0) delivers the least-significant bit (LSB) and SO (I/O1) delivers the most-significant bit (MSB) of each data byte on every falling edge of SCK. This doubles effective throughput versus standard SPI Read Array (03h), achieving up to 100 MB/s effective bandwidth at 50 MHz - significantly accelerating boot code loading in the AT25DN011-MAHFGP-Y.

What is the purpose and accessibility of the OTP security register in the AT25DN011-MAHFGP-Y?

The AT25DN011-MAHFGP-Y includes a 128-byte One-Time Programmable (OTP) security register accessible via opcodes 9Bh (program) and 77h (read). Once programmed, bits cannot be altered - making it ideal for storing immutable device identifiers, cryptographic keys, or calibration constants. Unlike main array storage, the OTP register is electrically isolated and unaffected by erase commands, ensuring persistent security binding within the AT25DN011-MAHFGP-Y.

Can the AT25DN011-MAHFGP-Y operate reliably below 2.3 V?

No - the AT25DN011-MAHFGP-Y has a specified minimum supply voltage of 2.3 V. Operation below this threshold is outside absolute maximum ratings and may result in undefined behavior, including failed program/erase operations, corrupted reads, or inability to exit power-down modes. The 2.3 V lower limit is rigorously tested and guaranteed across the full industrial temperature range for the AT25DN011-MAHFGP-Y.
