Description and Introduction

32 Mbit (2Mb x16, Boot Block) 3V Supply Flash Memory The **M28W320FCT70N6E** is a flash memory device manufactured by **STMicroelectronics (STM)**. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Memory Type:** NOR Flash  
- **Density:** 32 Mbit (4 MB)  
- **Organization:** 4M x 8-bit or 2M x 16-bit  
- **Supply Voltage:** 2.7V - 3.6V  
- **Access Time:** 70 ns  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** TSOP-48  

### **Descriptions:**
- The **M28W320FCT70N6E** is a **3V-only** flash memory device designed for high-performance embedded applications.  
- It supports **asynchronous read operations** and features a **flexible sector architecture** for efficient data storage.  
- It is **compatible with JEDEC standards** and offers **low power consumption** in both active and standby modes.  

### **Features:**
- **Sector Architecture:**  
  - **Uniform 64 KB sectors** (or other configurations depending on variant).  
  - Supports **individual sector erase** and **full chip erase**.  
- **Programming & Erase:**  
  - **Byte/Word Programming** (with automatic erase before programming).  
  - **Fast Erase Time:** Typical **0.7s per sector**.  
- **Reliability & Endurance:**  
  - **Minimum 100,000 erase/program cycles per sector**.  
  - **20-year data retention**.  
- **Hardware & Software Protection:**  
  - **Block protection** to prevent accidental writes.  
  - **Security ID** for authentication.  
- **Low Power Modes:**  
  - **Standby current:** < 50 µA (typical).  
  - **Active read current:** < 20 mA (typical).  

This flash memory is commonly used in **automotive, industrial, and consumer electronics** applications requiring reliable non-volatile storage.  

(Note: For exact sector configurations or additional details, refer to the official STMicroelectronics datasheet.)

Application Scenarios & Design Considerations

32 Mbit (2Mb x16, Boot Block) 3V Supply Flash Memory

Alternative Part Number

  • S29GL032N90TFI040 --: 32 Mbit 3V parallel NOR flash in TSOP-48, same density and interface class as the original, widely available and pin-compatible in most designs.
  • MX29LV320EBTI-70G --: 32 Mbit 3V boot-sector NOR flash with compatible command set and TSOP-48 footprint, a common drop-in replacement for ST M28W series parts.
  • SST39VF3201B-70-4I-EKE --: 32 Mbit 3V parallel NOR flash in TSOP-48 with similar timing and interface, suitable as a functional substitute when exact ST part is unavailable.
  • JS28F320J3D75A --: Intel/Micron StrataFlash 32 Mbit parallel NOR flash in TSOP-56, same 3 V supply and similar access time, a common drop-in replacement for ST M28W series.
  • AM29LV320DT-90EI --: 32 Mbit 3 V boot-sector NOR flash with x16 organization and similar timing, a legacy-compatible substitute for the M28W320FCT.
