Description and Introduction

8-Digit, Microprocessor- Compatible, LED Display Decoder Driver The ICM7228DIJI is a product from **Intersil** (not Intelsil), which is a manufacturer known for its integrated circuits. Below are the factual specifications, descriptions, and features of the ICM7228DIJI:

### **Specifications:**
- **Manufacturer:** Intersil  
- **Part Number:** ICM7228DIJI  
- **Type:** 8-Digit Microprocessor-Compatible LED Display Driver  
- **Package:** 28-Pin PLCC (Plastic Leaded Chip Carrier)  
- **Operating Voltage:** 4.5V to 6V  
- **Display Type:** Drives Common Cathode LED Displays  
- **Interface:** Microprocessor-Compatible (4-bit parallel or serial)  
- **Maximum Clock Frequency:** 2MHz  
- **Digit Drive Outputs:** 8 (Multiplexed)  
- **Segment Drive Outputs:** 7 (plus decimal point)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
- The ICM7228DIJI is an 8-digit LED display driver designed for interfacing with microprocessors.  
- It supports multiplexed driving of common cathode LED displays, reducing the number of required connections.  
- It can be configured for either 4-bit parallel or serial data input.  
- The device includes on-chip memory (digit registers) and control logic for display multiplexing.  

### **Features:**
- **Microprocessor-Compatible:** Supports direct interfacing with 4-bit parallel or serial data input.  
- **Multiplexed Display Drive:** Reduces external component count by multiplexing digit and segment signals.  
- **On-Chip Memory:** Stores digit data internally for display refresh.  
- **Flexible Configuration:** Can be used in various display modes (e.g., 8-digit, 7-segment + decimal point).  
- **Low Power Consumption:** Suitable for battery-powered applications.  
- **Wide Operating Temperature Range:** Supports industrial and automotive applications.  

This information is based on the manufacturer's datasheet and technical documentation. For detailed electrical characteristics and application circuits, refer to the official Intersil datasheet.

Application Scenarios & Design Considerations

8-Digit, Microprocessor- Compatible, LED Display Decoder Driver

Alternative Part Number

  • MAX7219CNG+ --: 8-digit LED display driver in DIP package offering similar multiplexed display drive functionality as the ICM7228 display driver.
  • MC14489BDWE --: Multiplexed LED display driver with similar segment/digit drive capability, suitable as a functional substitute for display driving applications.
  • CD4511BE --: BCD-to-7-segment latch/decoder/driver in DIP, a common alternative for 7-segment display driving when full 8-digit multiplexing is not required.
  • MAX7221CNG+ --: Similar 8-digit LED display driver with SPI interface and better noise immunity, suitable replacement for display driving functions.
  • ICM7218BIJI --: Same Intersil 8-digit LED display driver family with similar interface and pinout, offering a close functional match.
