Description and Introduction

4 Digit Counter/Decoder/Driver The ICM7225IPL is a 4-digit LED display driver manufactured by Harris Semiconductor (now part of Intersil). Here are its key specifications, descriptions, and features:  

### **Manufacturer:**  
- **HAR** (Harris Semiconductor, later acquired by Intersil)  

### **Specifications:**  
- **Type:** 4-Digit, 7-Segment LED Display Driver  
- **Interface:** Parallel or Serial (Multiplexed)  
- **Supply Voltage:** 4.5V to 6V (5V typical)  
- **Current Consumption:** Low power (suitable for battery applications)  
- **Segment Drive Capability:** Up to 25mA per segment  
- **Multiplexing Frequency:** Internally generated (~500Hz typical)  
- **Package:** 28-pin DIP (Dual In-line Package)  

### **Descriptions:**  
- The ICM7225IPL is designed to drive 4-digit, 7-segment LED displays with minimal external components.  
- It includes an on-chip multiplex scan oscillator, eliminating the need for an external clock.  
- Supports both common anode and common cathode displays via configuration.  
- Features a flexible input interface (parallel or serial) for microcontroller interfacing.  

### **Features:**  
- **Integrated Multiplexing:** Reduces external component count.  
- **Brightness Control:** Adjustable via external resistor.  
- **Data Retention:** Maintains display data during power-down.  
- **Decoding:** On-chip BCD-to-7-segment decoder.  
- **Low Power Operation:** Suitable for battery-powered devices.  

This information is based solely on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

4 Digit Counter/Decoder/Driver

Alternative Part Number

  • ICM7217IPL --: Same Intersil ICM72xx family of 4-digit LED display counters/drivers in a 40-pin DIP package, offering similar counter/driver functionality and pin-compatible footprint for many designs.
  • MAX7219CNG --: Widely used 8-digit LED display driver in a 24-pin DIP that can replace the display-driving function of the ICM7225 in many applications, with serial interface and multiplexed drive.
  • CD74HC4017E --: Decade counter/divider in a standard DIP package that can substitute the counting function in simpler designs, though external display drive circuitry may be required.
  • ICM7216BIPL --: Same ICM72xx family of LED display drivers/counters from Maxim, similar DIP-40 package and supply requirements, often used as a functional substitute in display counter designs.
  • ICM7217AIPL --: Related Maxim 4-digit programmable counter/display driver in the same series with comparable pinout and electrical characteristics, suitable for similar counting applications.
  • MC14553BCP --: 3-digit BCD counter with multiplexed display drive from a different manufacturer and series, offering similar counting and display-drive functionality as a cross-vendor alternative.
