CMOS High Performance Programmable DMA Controller The 82C37A is a high-performance programmable DMA (Direct Memory Access) controller manufactured by Harris Semiconductor. Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** HARRIS  
- **Part Number:** 82C37A  
- **Type:** CMOS Programmable DMA Controller  
- **Operating Voltage:** 5V  
- **Technology:** CMOS  
- **Package:** 40-pin DIP (Dual In-line Package) or other available packages  
- **Operating Temperature Range:** Commercial (0°C to +70°C) or Industrial (-40°C to +85°C)  

### **Descriptions:**  
The 82C37A is a high-speed, low-power DMA controller designed for use in microprocessor-based systems. It facilitates high-speed data transfers between memory and I/O devices without CPU intervention, improving system performance. It is compatible with the Intel 8237A DMA controller but offers enhanced CMOS technology for lower power consumption and higher reliability.  

### **Features:**  
- **Four Independent DMA Channels:** Supports four separate channels for data transfer.  
- **Memory-to-Memory Transfer Capability:** Allows direct data movement between memory blocks.  
- **Programmable Priority Modes:** Fixed or rotating priority modes for channel arbitration.  
- **Auto-Initialization:** Channels can be automatically reinitialized after transfer completion.  
- **High-Speed Operation:** Supports data transfer rates up to 1.6 MB/s.  
- **Cascading Support:** Multiple 82C37A devices can be cascaded for additional channels.  
- **Software Compatibility:** Fully compatible with the Intel 8237A DMA controller.  
- **Low Power Consumption:** CMOS technology ensures efficient power usage.  
- **Wide Operating Temperature Range:** Available in commercial and industrial grades.
