Description and Introduction

Fixed And Programmable Timer/Counters The ICM7240IJE is a real-time clock (RTC) integrated circuit manufactured by **Intersil** (now part of Renesas Electronics). Below are the key specifications, descriptions, and features based on available data:

### **Specifications:**
- **Manufacturer:** Intersil  
- **Type:** Real-Time Clock (RTC)  
- **Package:** 18-pin DIP (Dual In-line Package)  
- **Supply Voltage:** Typically **5V**  
- **Clock Frequency:** Standard **32.768 kHz** (for timekeeping)  
- **Timekeeping Accuracy:** Dependent on crystal oscillator stability  
- **Interface:** Parallel (for communication with microprocessors)  
- **Operating Temperature Range:** Industrial-grade (**-40°C to +85°C**)  

### **Descriptions:**
- The **ICM7240IJE** is a **CMOS-based** real-time clock IC designed for timekeeping applications.  
- It includes counters for **seconds, minutes, hours, day, date, month, and year** (with leap-year compensation).  
- Features **alarm functionality** and can generate interrupts for time-based events.  
- Designed for use in **industrial, embedded systems, and computing applications**.  

### **Features:**
- **Low power consumption** (CMOS technology).  
- **Battery backup support** for maintaining timekeeping during power loss.  
- **Programmable alarm** with interrupt output.  
- **Parallel interface** for easy integration with microcontrollers or processors.  
- **Industrial temperature range** for harsh environments.  
- **On-chip oscillator** for driving an external **32.768 kHz crystal**.  

This information is based on historical Intersil datasheets. For exact details, refer to the original **Intersil ICM7240IJE datasheet**.
