M25P10-AVMN3TP/Y 概要
A serial NOR Flash memory is a nonvolatile storage IC that stores code and data in a NOR array accessed bit-parallel through a serial peripheral interface (SPI). In the embedded-systems hierarchy it sits under the flash memory family, alongside parallel NOR and NAND Flash, and is typically used as boot code storage for microcontrollers, FPGAs, and system-on-chip devices where a small, low-pin-count, low-cost nonvolatile memory is required.
Key features of the M25P10-A include page programming of 1 to 256 bytes with a typical page program time of 1.4 ms, sector erase of 256 Kbit sectors in 0.8 s typical, and a full bulk erase of the 1 Mbit array in 2.5 s typical. The device offers advanced write-protection mechanisms, including block protection and a hardware write-protect (W#) pin, plus a HOLD# pin that suspends serial communication without deselecting the device.
Architecturally, the M25P10-A descends from the Numonyx (formerly STMicroelectronics) M25Pxx family, which Micron acquired and continues as part of its low-density serial NOR portfolio. Commands, status registers, and timing follow the industry-standard SPI Flash command set (READ, FAST_READ, PAGE PROGRAM, SECTOR ERASE, BULK ERASE, WREN, RDSR), simplifying driver reuse across designs.
Typical applications include MCU boot-code and firmware storage in industrial control, FPGA configuration bitstream storage, set-top boxes, networking line cards, and automotive body modules where the -40C to +125C operating range is required.
When designing with this device, keep the SPI clock within the 50 MHz limit for fast read commands and observe proper HOLD# timing to avoid bus contention; add series resistors on MISO if trace lengths are long.

主な用途
M25P10-AVMN3TP/Y の用途: 6 件s: MCU Boot Code Storage, FPGA Configuration Bitstream Storage, Industrial Control and Automation Modules, Set-Top Box and Consumer AV Peripherals, Networking Line Cards and Router Firmware, Automotive Body and Comfort Modules.
MCU Boot Code Storage
The M25P10-AVMN3TP/Y stores boot code and firmware for 8-, 16-, and 32-bit microcontrollers that lack sufficient internal flash. Its 1 Mbit (128 Kbyte) density covers typical bootloader plus application images, and the 50 MHz SPI interface with FAST_READ keeps boot latency low even at modest clock rates. The hardware W# pin and block protection prevent accidental corruption of the boot image during runtime parameter writes, while the -40C to +125C range supports industrial and automotive-adjacent deployments. Placed on the standard QUAD/SPI bus with 10k pull-up on S#, the device draws negligible standby current and adds no switching noise to sensitive analog rails.
おすすめ
FPGA Configuration Bitstream Storage
The M25P10-AVMN3TP/Y serves as a master-serial configuration memory for small FPGAs and CPLDs, storing the bitstream that is clocked in at power-up. At 50 MHz SPI, a compact configuration image loads in milliseconds, and the industry-standard SPI command set (READ / FAST_READ) is directly compatible with common FPGA master-serial loaders. The advanced write-protection mechanisms guarantee the bitstream survives field firmware updates to other storage regions. Because the 8-SOIC footprint is shared across the M25Pxx family from 1 Mbit to 32 Mbit, designers can double or quadruple configuration capacity later with no PCB change - a decisive advantage for product roadmaps that add larger FPGAs.
おすすめ
Industrial Control and Automation Modules
In PLC I/O cards, motor drive panels, and factory sensors, the M25P10-AVMN3TP/Y stores calibration constants, device identity, and firmware images. The -40C to +125C datasheet operating range tolerates control-cabinet temperature excursions, and the 2.7 V to 3.6 V single supply integrates cleanly with 3.3 V logic rails. Page programming of 1 to 256 bytes in 1.4 ms typical allows frequent small-parameter writes without blocking real-time tasks, and the 0.8 s typical 256 Kbit sector erase confines maintenance windows. The hardware write-protect pin can be gated by the host MCU to lock parameter sectors during machine operation, preventing corruption from errant bus traffic.
おすすめ
Set-Top Box and Consumer AV Peripherals
Consumer audio/video peripherals such as set-top boxes, HDMI accessories, and IR remotes use the M25P10-AVMN3TP/Y to store firmware, IR code tables, and HDCP-adjacent configuration data. Its low pin-count SPI interface minimizes PCB layers in cost-sensitive consumer boards, and the small 8-SOIC body (0.154 in width) fits dense layouts. Bulk erase of the full 1 Mbit array in 2.5 s typical supports factory reprogramming at end-of-line test, while block protection secures factory-programmed regions from consumer-side updates. As of 2026-09-04, unit pricing below one dollar at LCSC ($0.7586) keeps the bill-of-materials impact minimal for high-volume consumer builds.
おすすめ
Networking Line Cards and Router Firmware
Networking equipment uses the M25P10-AVMN3TP/Y on line cards and management modules to store MAC addresses, board serial numbers, and golden firmware images. The 50 MHz SPI bus keeps POST-time reads fast, and the HOLD# pin lets the host suspend a read transaction mid-stream to service a higher-priority bus master without deselecting the device - useful in shared-SPI topologies. The -40C to +125C rating covers unventilated telecom enclosures. Engineers provisioning legacy Cisco/Broadcom reference designs that specify M25Pxx devices can drop this part in directly; however, given the family EOL status, new networking designs should pair the layout with a second-source footprint such as the Alliance Memory M25P10-AVMN6TP.
おすすめ
Automotive Body and Comfort Modules
Body control modules, seat controllers, and lighting modules leverage the M25P10-AVMN3TP/Y's -40C to +125C operating range for data storage in harsh under-dash and engine-bay-adjacent environments. The device stores DTC history, configuration variants, and end-of-line calibration data. Its advanced write-protection mechanisms, combined with the hardware W# pin driven by a supervisor output, ensure stored data survives power glitches and brownouts common in 12 V automotive rails. Typical page program time of 1.4 ms permits parameter logging during drive cycles. Note that AEC-Q100 qualification status for this exact ordering part number should be confirmed with Micron documentation before use in safety-relevant positions.

設計ノート
Micron has announced end-of-life for all low-density memory solutions, including the M25P family (per the Renesas-published 'Conversion Guide Micron EOL M25P Products'). Do not start new production designs on this MPN without a lifecycle plan: qualify the Alliance Memory M25P10-AVMN6TP as a second source now, or lay out the board to accept higher-density M25Pxx parts in the same 8-SO footprint. Also confirm HOLD#/W# pull-up resistors (10k to VCC) are present; floating pins can cause spurious write enables at power-up.
At the full 50 MHz SPI clock, keep SCK, D, and Q traces under 10 cm where practical and use a series 22-33 ohm resistor on SCK to control ringing. The FAST_READ command requires an 8 dummy-clock cycle after the address; firmware that omits these dummy cycles reads corrupted data at high clock rates but may appear to work at low clock rates - a classic intermittent bug. Ground return under the SPI bus on a contiguous reference plane prevents crosstalk onto Q.
Power the device from the 3.3 V rail with a 100 nF ceramic decoupling capacitor placed within 3 mm of pin 8 (VCC) to pin 4 (VSS), plus a 4.7 uF bulk capacitor per SPI bus segment. Erase and program operations draw transient current bursts; a soft local reservoir prevents VCC droop that could corrupt an in-progress page program. Ensure W# is actively driven high by the host before issuing any program or erase command, as W# low globally latches write protection regardless of software commands.
コンプライアンス情報
Compliance status was not stated in the retrieved distributor data; verify RoHS/REACH status on Micron's official product page or the M25P10-A datasheet before release. AEC-Q100 status for this ordering part number must be confirmed directly with Micron documentation.
