Description and Introduction

2K-bit 2-WIRE SERIAL CMOS EEPROM with Permanent and Reversible Write-Protection The IS34C02B-2ZLI is a 2K-bit (256 x 8) serial I²C EEPROM manufactured by ISSI (Integrated Silicon Solution Inc.). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Memory Size:** 2K-bit (256 bytes)
- **Interface:** I²C (2-wire serial interface)
- **Operating Voltage:** 1.7V to 5.5V
- **Operating Temperature Range:** -40°C to +85°C
- **Write Cycle Endurance:** 1,000,000 cycles (minimum)
- **Data Retention:** 100 years (minimum)
- **Clock Frequency:** Up to 400 kHz (Fast-mode I²C)
- **Page Write Buffer:** 8 bytes
- **Package:** 8-lead SOIC, TSSOP, or PDIP (varies by suffix)

### **Descriptions:**
- The IS34C02B-2ZLI is a low-power, byte-erasable EEPROM with a built-in write-protect feature.
- It supports sequential and random read operations.
- The device includes a write protect pin (WP) to prevent accidental writes.
- It is compatible with the I²C protocol and supports standard (100 kHz) and fast (400 kHz) modes.

### **Features:**
- **Low Power Consumption:**  
  - Active read current: 1 mA (max)  
  - Standby current: 1 µA (max)  
- **Hardware Write Protection:** WP pin enables/disables write operations.
- **Self-Timed Write Cycle:** Automatic erase and program cycle (5 ms max).
- **Noise Immunity:** Schmitt trigger inputs for improved noise filtering.
- **ESD Protection:** > 4,000V (Human Body Model).
- **Industrial-Grade:** Supports extended temperature range (-40°C to +85°C).

This device is commonly used in industrial, automotive, and consumer electronics for non-volatile data storage.
