SPI Serial E2PROM The X25C02P is a 2K-bit Serial CMOS EEPROM manufactured by XICOR (now part of Intersil). Here are its key specifications, descriptions, and features:
### **Specifications:**
- **Memory Capacity:** 2K-bit (256 x 8)
- **Interface:** Serial (SPI-compatible)
- **Operating Voltage:** 2.7V to 5.5V
- **Operating Temperature Range:** -40°C to +85°C
- **Write Cycle Time:** 5ms (typical)
- **Data Retention:** 100 years (minimum)
- **Endurance:** 1,000,000 write cycles per byte
### **Descriptions:**
- The X25C02P is a low-power, byte-alterable EEPROM with a simple 3-wire serial interface.
- It supports sequential and random read operations.
- Features a software-controlled write protection mechanism.
- Designed for applications requiring non-volatile storage with minimal pin count.
### **Features:**
- **SPI-Compatible Interface:** Uses clock (SCK), chip select (CS), data in (SI), and data out (SO) signals.
- **Write Protection:** Software-controlled write protection for the entire memory or partial blocks.
- **Low Power Consumption:** Active current of 3mA (max), standby current of 10μA (max).
- **Page Write Mode:** Allows writing up to 16 bytes in a single operation.
- **Built-in Error Detection:** Includes a write enable latch and write cycle completion detection.
This EEPROM is commonly used in industrial, automotive, and consumer electronics for storing configuration data, calibration settings, and other small non-volatile data.
