N25Q032A13EV741 概要
A NOR Flash memory is a type of non-volatile memory that retains stored data without power. Within the memory hierarchy, NOR Flash sits alongside NAND Flash and EEPROM as a semiconductor storage device; unlike NAND, NOR Flash supports random access to any address, which makes it the preferred technology for storing boot code, firmware, and executable code directly on the CPU address bus. It connects to a host microcontroller or processor through the Serial Peripheral Interface (SPI), a four-wire serial bus.
Key features of the N25Q032A13EV741 include its 108 MHz SPI clock capability (supporting double data rate operation in the N25Q family), 32Mbit density organized as 8M x 4, a 2.7V to 3.6V supply range suitable for standard 3V systems, and page programming with a write cycle time of 8 ms (word) and 5 ms (page) according to distributor specification listings.
Technically, the device belongs to Micron's N25Q P-series family, which introduced the enhanced SPI protocol supporting command-based double transfer rate (DTR) reads, allowing effective throughput near 108 MB/s in DDR mode. Sector and block erasure with hardware write protection on the WP# pin protects firmware against accidental corruption. The HOLD# pin suspends serial communication without deselecting the device in multi-drop SPI buses.
Typical applications include embedded boot-code storage for microcontrollers and FPGAs, telecom equipment firmware banks (distributor listings categorize the part under the Telecom interface segment), industrial control modules, and set-top box or networking line cards requiring reliable code shadowing. Its 108 MHz DDR read throughput allows XIP (execute-in-place) operation that reduces RAM copy time at boot.
When designing with this device, note that the part status is obsolete, so new designs should qualify the newer A-step suffix variants (e.g., N25Q032A13EV7A0) or a second source before committing to the layout. Ensure WP# and HOLD# pins are properly terminated in SPI buses that do not use these functions.

主な用途
N25Q032A13EV741 の用途: 6 件s: Embedded Boot Code Storage, FPGA Configuration Memory, Telecom Equipment Firmware Banks, Industrial Control and PLC Modules, Networking and Set-Top Box Line Cards, Automotive and Rugged Repair/Service Stock.
Embedded Boot Code Storage
The N25Q032A13EV741 is well suited to storing boot code and firmware for microcontrollers and embedded processors. Its 32Mbit capacity comfortably holds bootloader plus application images, and the 108 MHz SPI clock reduces code-fetch latency compared with legacy 33-50 MHz SPI Flash, cutting boot time measurably in code-shadowing architectures. In a typical circuit, the device hangs off the MCU's dedicated SPI/QSPI port with 10k-ohm pull-ups on S# and HOLD#, and WP# strapped high unless write protection is required. Because the part is obsolete, designers should qualify the N25Q032A13EV7A0 A-step variant in new boards while using the 741 only for repair and last-time-buy stock.
おすすめ
FPGA Configuration Memory
Mid-range FPGAs commonly use 32Mbit SPI NOR Flash as the configuration bitstream store, and the N25Q032A13EV741 fits this role with 108 MHz serial reads that shorten configuration time versus 50 MHz-class memories. Placed on the FPGA's dedicated configuration SPI bus with S# driven by the FPGA's configuration controller, the device supports fast read commands used by most configuration engines. Designers should confirm the FPGA configuration preamble and read-opcode support, and reserve headroom because 32Mbit is the practical ceiling for larger bitstreams. The identical pinout of the N25Q032A13EV7A0 allows seamless migration without layout changes.
おすすめ
Telecom Equipment Firmware Banks
Distributor listings categorize the N25Q032A13EV741 under the telecom application segment, where line cards, network processors, and control modules require reliable non-volatile code storage. NOR Flash random-access behavior supports execute-in-place (XIP) operation, letting control CPUs run code directly from Flash and reduce boot-time RAM copies. The 2.7V-3.6V supply matches standard telecom 3.3V rails, and the 8-lead VDFPN package conserves board area on dense line cards. Hardware write protection via WP# guards firmware against corruption during field updates. Given obsolescence, telecom maintenance programs should secure last-time-buy quantities or cross-qualify the N25Q032A13EV7A0.
おすすめ
Industrial Control and PLC Modules
Industrial controllers, I/O modules, and drives benefit from the N25Q032A13EV741's non-volatile parameter and firmware storage. The 32Mbit array holds firmware plus calibration tables, and the -40C-capable industrial variants of the N25Q032A family operate across harsh temperature ranges typical of factory-floor enclosures. The SPI interface isolates memory traffic from parallel buses, improving noise immunity in electrically noisy motor-control environments, while sector erasure allows wear-leveled parameter logging. Note that the 741 ordering code is obsolete; industrial designers migrating designs should use the A-step N25Q032A13EV7A0, which is pin-to-pin identical and preserves all electrical specifications.
おすすめ
Networking and Set-Top Box Line Cards
Set-top boxes, routers, and switching line cards use 32Mbit SPI NOR Flash for boot loaders and golden firmware images. The N25Q032A13EV741's 108 MHz DDR-capable interface delivers effective read throughput approaching 108 MB/s in the N25Q family's DDR mode, accelerating startup and reducing perceived boot latency in consumer networking products. Its compact 8-lead VDFPN package fits the tight real estate of line-card layouts, and dual-image firmware update schemes fit naturally within the 32Mbit array. For new consumer designs, choose the N25Q032A13EV7A0 or larger N25Q064/N25Q128 variants to secure long-term supply.
おすすめ
Automotive and Rugged Repair/Service Stock
Because the N25Q032A13EV741 is obsolete, a major remaining use case is component repair and service for installed-base electronics - telecom racks, industrial drives, and consumer platforms programmed with this exact die revision. Service organizations match the original 741 die revision to avoid firmware incompatibilities introduced by A-step errata fixes, making the 741 code valuable for exact-fit spares. When stocking, verify authenticity via marking inspection and functional read of the device ID, since obsolete memory is counterfeit-prone. For long-term service lines, dual-qualify the N25Q032A13EV7A0 so both die revisions can be programmed into the same sockets.

設計ノート
The N25Q032A13EV741 is reported obsolete in distributor data (ABC-Semi listing, 2026). Do not release new production designs against this ordering code. Qualify the N25Q032A13EV7A0 (identical VDFPN-8 footprint, newer A-step die) or N25Q032A13EF4A0F before tape-out. When dual-sourcing on existing boards, verify the READ ID / device ID opcode results, since A-step die can report different identification bytes that some firmware uses to branch command sets.
Place a 100 nF ceramic decoupling capacitor within 3 mm of the VDD pin (pin 8) with a solid via to the ground plane referenced to VSS (pin 4). Keep the SPI clock (SCK) trace short and route it away from SO/SI to limit crosstalk at 108 MHz operation - at this clock rate, trace stubs beyond a few centimeters require series termination (typically 22-33 ohm) on SCK. Strap WP# and HOLD# with 10k-ohm pull-ups if unused, preventing floating inputs from entering quad or hold modes spuriously.
At 108 MHz the N25Q032A edge rates make signal integrity non-trivial: ensure a continuous ground reference under the SPI bus, limit bus length on multi-drop topologies, and use the extended read command set (fast read, DDR read) rather than legacy 03h read for full throughput. When using dual/quad IO commands, confirm WP#/IO2 and HOLD#/IO3 net loading is symmetric. Estimated: with typical 30 pF bus loading and 108 MHz SCK, allow rise/fall times under 3 ns to maintain setup/hold margins stated in the family datasheet.
Operate the device from a regulated 3.0-3.3 V rail within the 2.7-3.6 V datasheet window. Estimated: with VDD at 3.3 V and typical page-program current for the N25Q class (on the order of 15-20 mA during program/erase), budget the local rail accordingly - a 100 mA-class LDO such as Micron-agnostic small regulators suffices for a single device, but add bulk capacitance if multiple Flash devices program concurrently on a shared rail.
コンプライアンス情報
The retrieved web data does not include compliance declarations for this obsolete ordering code. N25Q family parts were generally produced RoHS-compliant, but confirm with Micron compliance support before use in regulated production.
