Description and Introduction

SerialFlash? Memory With Block LockTM Protection The X25F016 is a 16-Mbit (2M x 8) Serial Flash Memory manufactured by Xicor (now part of Intersil). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Memory Size:** 16 Mbit (2,097,152 bytes)  
- **Organization:** 2,097,152 x 8 bits  
- **Interface:** SPI (Serial Peripheral Interface)  
- **Supply Voltage:** 2.7V to 3.6V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Clock Frequency:** Up to 20 MHz  
- **Page Size:** 256 bytes  
- **Sector Size:** 4 Kbytes (uniform sectors)  
- **Block Size:** 64 Kbytes  
- **Write Cycle Time:** 5 ms (typical)  
- **Endurance:** 100,000 write cycles per sector  
- **Data Retention:** 100 years  

### **Descriptions:**
- The X25F016 is a non-volatile flash memory device with a serial SPI interface, designed for high-speed data transfer.  
- It supports byte-level and page-level programming, as well as sector and bulk erase operations.  
- The device features a software-controlled write protection mechanism and a hardware write-protect pin (WP#).  
- It includes a hold pin (HOLD#) to pause serial communication without resetting the device.  

### **Features:**
- **SPI Modes:** Supports modes 0 and 3.  
- **Low Power Consumption:**  
  - Active Read Current: 15 mA (typical)  
  - Standby Current: 10 µA (typical)  
- **Write Protection:**  
  - Software-controlled block protection (BP0, BP1 bits)  
  - Hardware write-protect pin (WP#)  
- **Fast Erase & Program:**  
  - Sector Erase Time: 300 ms (typical)  
  - Chip Erase Time: 15 seconds (typical)  
- **Status Register:** Provides write-in-progress and write-protection status.  
- **Package Options:**  
  - 8-lead SOIC (208-mil)  
  - 8-lead PDIP (300-mil)  

This device is commonly used in embedded systems, industrial applications, and consumer electronics requiring reliable non-volatile storage.  

(Note: Since Xicor was acquired by Intersil, further technical support may be available through Renesas Electronics, which later acquired Intersil.)

Application Scenarios & Design Considerations

SerialFlash? Memory With Block LockTM Protection

Alternative Part Number

  • AT25F512 --: SPI serial flash in the same 512Kbit class with compatible SPI interface and pinout, widely available as a drop-in functional replacement.
  • M25P16 --: 16Mbit SPI serial flash with standard SPI command set and SOIC package options, suitable for designs needing higher density than the original.
  • W25X16 --: 16Mbit SPI serial flash with industry-standard pinout and command set, a common and cost-effective alternative for serial flash applications.
  • SST25VF016B --: 16 Mbit SPI serial flash memory offering similar capacity and interface, commonly used as an alternative to Xicor serial flash devices.
  • AT25F512B --: SPI serial flash in the same 512Kbit class with compatible command set and pinout, widely available and well documented.
