概述

Description

MT25QU256ABA8E12-0AUT is Micron’s 256‑Mbit Serial Quad I/O (SQI/QPI) flash memory in an 8‑pin package, automotive-grade variant (-AUT).
Key points:
- Capacity: 256 Mb (32 MB)
- Interface: Quad I/O SPI with QPI support; also operable in standard SPI/dual I/O modes
- Speed: up to QPI ~133 MHz (typical), or up to 104 MHz in SPI mode (depends on mode)
- Features: fast read, page program (typically 256 bytes), sector/block erase (4 KB/32 KB/64 KB), sector protection, security/OTP options, deep power-down
- Voltage: typically 2.7–3.6 V
- Temperature: automotive grade, extended range (approx. -40°C to 125°C)
- Package: 8-pin (e.g., SOIC/SSOP/USON)
- Applications: boot memory and code/data storage for microcontrollers, embedded systems, automotive ECUs and other high-reliability devices
Suffix AUT indicates the automotive-grade variant with enhanced reliability for harsh environments.

Features

Key features of MT25QU256ABA8E12-0AUT (typical):
- 256-Mbit serial NOR flash (32 MB)
- SPI and Quad I/O (QPI) interfaces for high-speed reads/writes
- 4-byte addressing support for full memory map (needed for 256 Mbit)
- Page program: 256-byte pages
- Erase modes: 4 KB sectors, 64 KB blocks, full-device erase
- High-speed read: SPI up to ~100–104 MHz; QPI faster (speeds vary by mode)
- Low power with deep power-down mode
- Security and protection: sector/block protection, configurable write protection
- Endurance/retention: typical endurance in the 100k–1M CE cycles per sector; long data retention
- Operating voltage: typically 2.7–3.6 V
- Operating temperature: industrial range (e.g., -40°C to 85°C)
- Package: 8-pin (SC-8/SO8) variants available
Note: exact operating voltage, temperature range, and speed can vary by package/revision; always verify with the specific datasheet for this exact part number.

Package

8‑pin SOP (SOIC) package.

Pinout

Pin count: 8 pins.
Function: 256‑Mbit Quad SPI (QSPI) serial NOR flash memory. Pins provide four data I/O lines (DQ0–DQ3), chip select (CS#), clock (CLK), power (VCC), and ground (GND).
