Description and Introduction

2 MBIT, LOW VOLTAGE, SERIAL FLASH MEMORY WITH 25 MHZ SPI BUS INTERFACE The M25P20 is a serial flash memory device manufactured by Numonyx (now part of Micron Technology). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Memory Capacity:** 2 Mbit (256 KB)  
- **Interface:** SPI (Serial Peripheral Interface)  
- **Operating Voltage:** 2.7V to 3.6V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Page Size:** 256 bytes  
- **Sector Size:** 4 KB (64 sectors total)  
- **Block Size:** 64 KB (4 blocks total)  
- **Clock Frequency:** Up to 50 MHz  
- **Write Time (Page Program):** 1.4 ms (typical)  
- **Erase Time (Sector):** 0.6 s (typical)  
- **Erase Time (Block):** 2 s (typical)  
- **Erase Time (Chip):** 30 s (typical)  
- **Data Retention:** 20 years  
- **Endurance:** 100,000 write/erase cycles per sector  

### **Descriptions:**
- The M25P20 is a non-volatile memory device that retains data without power.  
- It supports SPI modes 0 and 3 for communication with microcontrollers.  
- It features a flexible erase architecture (sector, block, or full chip erase).  
- The device includes a write protection mechanism (software and hardware-based).  

### **Features:**
- **SPI-Compatible Interface:** Supports standard SPI commands.  
- **Deep Power-Down Mode:** Reduces power consumption when inactive.  
- **Software & Hardware Protection:** Write protection via WP# pin or status register.  
- **Electronic Signature:** Contains a unique JEDEC ID for identification.  
- **High-Speed Read:** Supports fast read operations (up to 50 MHz).  
- **Reliable Data Storage:** Designed for industrial and automotive applications.  

This information is based solely on the M25P20 datasheet from Numonyx.
