概述

Description

M29W320DT70N6E is a 32‑Mbit NOR flash memory device (4 MB) with a parallel 8‑bit data bus. It’s designed for embedded firmware storage and fast random access.
Key features
- Capacity/organization: 32 Mbit, x8 data bus
- Supply and speed: operates at 2.7–3.6 V; 70 ns access time
- Interface: parallel NOR flash command set (READ, Read Status, Chip/Sector Erase, Byte/Word Program, etc.)
- Endurance/retention: typical erase cycles around 100K per sector; data retention ~20 years at 25°C
- Protection: sector/block protection and locking options
- Applications: boot ROM, code storage, firmware updates in microcontroller/SoC systems
Packages/pinout: available in common parallel flash packages (check datasheet for exact package types, pinout, and package options).
Note: exact sector sizes, timing nuances, and package variants vary by revision; refer to the official datasheet for precise specs and current packaging options.

Features

Here are concise features of M29W320DT70N6E:
- 32 Mbit NOR flash memory (4 M × 8 organization)
- 2.7–3.6 V supply (3.0 V nominal)
- Industrial temperature range: -40 °C to +85 °C
- Fast access: 70 ns maximum read access time
- Read modes: standard and fast read
- Erase: 4 KB sectors; 64 KB blocks; chip erase supported
- Program: page program up to 256 bytes
- Endurance/retention: ~100k P/E cycles; data retention ~20 years
- Security/protection: hardware sector protection (top/bottom), lock/ protection codes
- Power management: deep power-down mode and low standby current
- Suitable for embedded code and data storage with random access and reliable protection

Package

8-pin Small Outline IC package (SOIC/SOP), RoHS-compliant.

Pinout

Pin count: 48 pins (TSOP/LQFP48 common for this device).
Function: 32-Mbit NOR flash memory with a parallel interface (non-volatile storage for code/data). It provides 25 address lines (A0–A24), 8 data I/O lines (DQ0–DQ7), and standard flash control pins (chip select(s), output enable, write enable, reset) plus power pins (Vcc, GND, and VccQ). Suitable for random-access read/write and block/sector erase operations.

Manufacturer

Manufacturer: STMicroelectronics.
What kind of company: STMicroelectronics is a European multinational semiconductor company that designs and manufactures integrated circuits and other semiconductor devices.

Application

Application areas: 32‑Mbit parallel NOR flash used for code storage and boot ROMs in embedded systems. Supports execute-in-place (XIP) firmware in microcontrollers/MPUs. Suitable for automotive ECUs/infotainment firmware storage, industrial control systems, printers, set-top boxes, and other consumer electronics requiring reliable non-volatile program memory with fast random access.
