Description and Introduction

Micro Port Saver E2PROM Here are the factual details about part X84041S from manufacturer XICOR:

### **Specifications:**
- **Manufacturer:** XICOR  
- **Part Number:** X84041S  
- **Type:** Serial EEPROM (Electrically Erasable Programmable Read-Only Memory)  
- **Memory Size:** 4 Kbit (512 x 8)  
- **Interface:** I²C (2-wire serial interface)  
- **Supply Voltage:** 2.7V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Write Cycle Endurance:** 1,000,000 cycles  
- **Data Retention:** 100 years  
- **Package:** 8-lead SOIC (Small Outline Integrated Circuit)  

### **Descriptions:**
- The X84041S is a low-power, 4 Kbit serial EEPROM with an I²C interface.  
- It supports byte and page write operations (up to 16 bytes per page).  
- Features a built-in write-protect function via a hardware pin (WP).  
- Designed for high reliability and endurance in industrial and consumer applications.  

### **Features:**
- **Low Power Consumption:**  
  - Active Read Current: 1 mA (max)  
  - Standby Current: 5 µA (max)  
- **I²C-Compatible Interface:** Supports standard (100 kHz) and fast (400 kHz) modes.  
- **Hardware Write Protection:** WP pin allows blocking of write operations.  
- **Self-Timed Write Cycle:** Includes automatic erase and program cycles.  
- **Schmitt Trigger Inputs:** Improves noise immunity.  
- **RoHS Compliant:** Lead-free and environmentally friendly.  

This information is based solely on the manufacturer's datasheet for the X84041S.

Application Scenarios & Design Considerations

Micro Port Saver E2PROM

Alternative Part Number

  • DS28E01-100+ --: 1-Wire secure authenticator with SHA-1 engine, functionally similar to the X84041S secure memory device and widely available.
  • AT88SC0104C-SU --: CryptoMemory secure serial EEPROM with authentication, a common drop-in style alternative for secure key storage applications.
  • FM24CL64B-G --: F-RAM nonvolatile memory offering fast writes and high endurance, suitable replacement where the X84041S is used for configuration/secure data storage.
  • X5043S --: Same family of CPU supervisor with EEPROM and watchdog; Xicor's supervisor line was acquired by Intersil (now Renesas), so this is a direct functional successor with similar pinout and supply voltage.
  • CAT1161 --: I2C serial EEPROM supervisor with reset and watchdog in an 8-pin package, functionally comparable to the X84041S supervisor/EEPROM combination.
  • M41ST85W --: Supervisor with serial EEPROM and watchdog functions, offering similar system monitoring features as a cross-vendor replacement.
