STMicroelectronics M25P05-AVMN6P

Overview

M25P05-AVMN6P from STMicroelectronics is a 512 Kbit (64 Kbyte) serial NOR flash memory IC with SPI interface, 3.3 V supply voltage, 75 MHz maximum clock frequency, and uniform 4-Kbyte sector erase capability. It serves as non-volatile program/data storage in microcontroller-based embedded systems requiring compact, low-power code execution.

For engineers reviewing the M25P05-AVMN6P datasheet, M25P05-AVMN6P pinout, M25P05-AVMN6P application, or M25P05-AVMN6P equivalent, key selection criteria include sector architecture, write cycle endurance, data retention period, and SPI mode compatibility for boot memory or firmware update storage.

Technical Context

This device implements a standard SPI-compatible 4-wire interface (CLK, CS#, DI, DO) with support for dual I/O read commands and deep power-down mode. It uses NOR architecture enabling XIP (execute-in-place) operation and features a 256-byte page programming buffer with automatic write/erase timing control.

The memory array is organized as 128 sectors of 4 Kbytes each, with no block or bank hierarchy. Erase operations are limited to sector-level granularity, and the device supports software-controlled write protection via status register bits and hardware protection via WP# pin.

FAQ

What is the minimum supply voltage for M25P05-AVMN6P?

The M25P05-AVMN6P operates within a strict 3.0 V to 3.6 V supply range. Operation below 3.0 V is not guaranteed and may result in failed write/erase operations or corrupted data retention. The device does not support 2.7 V or wide-voltage operation.

Does M25P05-AVMN6P support quad SPI mode?

No. M25P05-AVMN6P supports only standard single I/O and dual I/O SPI read commands (e.g., 03h and 3Bh). It lacks quad I/O instruction support (e.g., 6Bh) and does not implement QPI or QOUT protocols. Quad mode functionality is available only in later M25PX and N25Q families.

How many write/erase cycles can each sector endure?

Each 4-Kbyte sector is rated for a minimum of 100,000 write/erase cycles under specified operating conditions (TA = 25 °C, VCC = 3.3 V). This endurance is validated per JEDEC JESD22-A117 and applies independently to each sector, enabling wear leveling across the array.

Is hardware write protection enabled by default at power-up?

No. Hardware write protection via the /WP pin is disabled by default after power-on reset. Protection must be explicitly enabled by pulling /WP low *and* setting the appropriate bits (SRWD and BP0–BP2) in the status register. Unintended writes remain possible until both conditions are met.
