Description and Introduction

Digital Line Interface Transceiver The XRT6164CD is a high-performance, low-power 64K x 16-bit CMOS static RAM (SRAM) manufactured by Xicor (now part of Intersil). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Organization:** 64K x 16-bit (1,048,576 bits)  
- **Technology:** CMOS  
- **Supply Voltage:** 5V ±10%  
- **Access Time:** 15 ns, 20 ns, 25 ns, 35 ns (depending on variant)  
- **Operating Current:** 70 mA (typical)  
- **Standby Current:** 10 µA (typical)  
- **Operating Temperature Range:**  
  - Commercial: 0°C to +70°C  
  - Industrial: -40°C to +85°C  
- **Package Options:** 44-pin PLCC, 44-pin TSOP  

### **Descriptions:**
- The XRT6164CD is a fast, low-power static RAM designed for applications requiring high-speed data access and low power consumption.  
- It features a fully static memory cell design, eliminating the need for external refresh.  
- The device is compatible with TTL levels and supports asynchronous operation.  

### **Features:**
- **High-Speed Performance:** Fast access times (15 ns to 35 ns).  
- **Low Power Consumption:**  
  - Active current: 70 mA (typical)  
  - Standby current: 10 µA (typical)  
- **Wide Operating Voltage Range:** 4.5V to 5.5V.  
- **Fully Static Operation:** No clock or refresh required.  
- **TTL-Compatible Inputs/Outputs:** Ensures easy interfacing with standard logic.  
- **Three-State Outputs:** Allows bus sharing in multi-memory systems.  
- **Industrial Temperature Support:** Available in extended temperature ranges.  
- **Reliable Packaging:** Offered in 44-pin PLCC and TSOP packages for compact designs.  

This information is based on the manufacturer's datasheet for the XRT6164CD SRAM.

Application Scenarios & Design Considerations

Digital Line Interface Transceiver

Alternative Part Number

  • MAX232CPE --: Industry-standard dual RS-232 driver/receiver in a DIP package, functionally similar to the XRT6164CD line interface function and widely available as a drop-in style replacement.
  • ST232CN --: Low-cost dual RS-232 transceiver in DIP-16 with comparable supply and interface characteristics, suitable as a functional substitute for the XRT6164CD.
  • ICL232CPE --: Classic dual RS-232 driver/receiver in a DIP package with similar pinout and electrical behavior, offering a reliable alternative when the original XR part is unavailable.
