Description and Introduction

32 Mbit, Low Voltage, Serial Flash Memory With 50MHz SPI Bus Interface The M25P32-VME6TG is a serial flash memory device manufactured by STMicroelectronics. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Manufacturer:**  
STMicroelectronics  

### **Specifications:**  
- **Memory Type:** NOR Flash  
- **Memory Size:** 32 Mbit (4 MB)  
- **Interface:** SPI (Serial Peripheral Interface)  
- **Supply Voltage:** 2.7V to 3.6V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Speed:** Up to 50 MHz clock frequency  
- **Sector Size:** 64 KB (uniform sectors)  
- **Page Size:** 256 bytes  
- **Write Protection:** Software and hardware options  
- **Endurance:** 100,000 write/erase cycles per sector  
- **Data Retention:** 20 years  

### **Descriptions:**  
- The M25P32-VME6TG is a high-performance serial flash memory designed for embedded systems requiring reliable non-volatile storage.  
- It supports SPI modes 0 and 3 for communication with microcontrollers and other host devices.  
- The device is organized in uniform 64 KB sectors, allowing flexible erase and programming operations.  

### **Features:**  
- **SPI Bus Interface:** Compatible with standard SPI protocols.  
- **Deep Power-Down Mode:** Ultra-low power consumption when inactive.  
- **Security Features:** Write protection via software (block protection bits) and hardware (WP# pin).  
- **Fast Erase & Programming:** Sector erase time (typical): 0.6s, page programming time (typical): 1.4ms.  
- **Industrial-Grade Reliability:** Suitable for harsh environments with extended temperature support.  
- **Package:** 8-lead SOIC (150 mil) for surface-mount applications.  

This information is based on STMicroelectronics' official documentation for the M25P32-VME6TG.

Application Scenarios & Design Considerations

32 Mbit, Low Voltage, Serial Flash Memory With 50MHz SPI Bus Interface

Alternative Part Number

  • W25Q32JVSSIQ --: 32Mbit SPI NOR flash in the same SOIC-8 package with compatible SPI interface and command set, widely used as a drop-in replacement for M25P32 devices.
  • S25FL032P0XMFI011 --: 32Mbit SPI NOR flash with pin-compatible SOIC-8 footprint and similar read/program/erase behavior, suitable for direct substitution.
  • MX25L3206EM2I-12G --: 32Mbit serial SPI NOR flash in SOIC-8 with compatible instruction set and timing, a common alternative when M25P32 is unavailable.
  • AT25SF321-SSHD-T --: 32Mbit SPI serial flash in SOIC-8 with compatible instruction set and timing, suitable as an alternative source for M25P32 applications.
