Description and Introduction

Programmable timer/counter The UPD71054G is a programmable interval timer (PIT) manufactured by NEC. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Manufacturer:** NEC (Nippon Electric Company)  

### **Specifications:**  
- **Type:** Programmable Interval Timer (PIT)  
- **Compatibility:** Functionally equivalent to the Intel 8254  
- **Operating Voltage:** Typically operates at **5V**  
- **Clock Frequency:** Supports clock inputs up to **8 MHz**  
- **Number of Timers:** Contains **three independent 16-bit counters**  
- **Interface:** Parallel, compatible with 8-bit microprocessors  
- **Operating Modes:** Six programmable modes (e.g., interrupt on terminal count, hardware retriggerable one-shot, rate generator, square wave generator, software-triggered strobe, hardware-triggered strobe)  
- **Package:** Likely available in **DIP (Dual In-line Package)** or similar format  

### **Descriptions:**  
- The UPD71054G is a CMOS-based programmable interval timer designed for timing and event-counting applications in microprocessor systems.  
- It is widely used in industrial control, instrumentation, and computer systems for generating accurate time delays, baud rate generation, and real-time clock functions.  
- Each of the three counters can be independently programmed for different modes and counting operations.  

### **Features:**  
- **Three Independent 16-bit Counters:** Allows flexible timing configurations.  
- **Multiple Operating Modes:** Supports six different timer/counter modes.  
- **Low Power Consumption:** CMOS technology ensures efficient power usage.  
- **Wide Compatibility:** Pin-compatible and functionally equivalent to the Intel 8254.  
- **Easy Integration:** Works seamlessly with 8-bit microprocessors.
