Description and Introduction

128K x 8 HIGH-SPEED CMOS STATIC RAM The IS61C1024-15K is a high-speed CMOS static RAM (SRAM) manufactured by Integrated Silicon Solution, Inc. (ISSI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Organization:** 128K x 8 (1Mbit)  
- **Operating Voltage:** 5V ±10%  
- **Access Time:** 15 ns  
- **Operating Current:** 70 mA (typical)  
- **Standby Current:** 10 mA (typical)  
- **Package:** 32-pin DIP (Dual In-line Package)  
- **Operating Temperature Range:** Commercial (0°C to +70°C) or Industrial (-40°C to +85°C)  
- **Pin Count:** 32  
- **I/O Type:** Common I/O  

### **Descriptions:**
- The IS61C1024-15K is a high-performance asynchronous SRAM designed for applications requiring fast access times and low power consumption.  
- It is commonly used in embedded systems, networking equipment, telecommunications, and industrial applications.  
- The device features a fully static operation, eliminating the need for external refresh or clock signals.  

### **Features:**
- **High-Speed Access:** 15 ns maximum access time.  
- **Low Power Consumption:** CMOS technology ensures low active and standby current.  
- **Wide Voltage Range:** Operates at 5V with ±10% tolerance.  
- **Tri-State Outputs:** Allows direct interfacing with common bus structures.  
- **Fully Static Operation:** No refresh cycles required.  
- **TTL-Compatible Inputs/Outputs:** Ensures easy integration with existing systems.  
- **Industrial-Grade Option:** Available for extended temperature range applications.  

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

Application Scenarios & Design Considerations

128K x 8 HIGH-SPEED CMOS STATIC RAM

Alternative Part Number

  • CY7C1021-15VC --: Pin-compatible 64K x 16 asynchronous SRAM with 15 ns access time, widely used as a drop-in alternative to the IS61C1024 in the same SOJ package.
  • AS7C1024-15JC --: Direct functional equivalent 64K x 16 SRAM with 15 ns speed grade, commonly stocked as a second-source replacement for ISSI IS61C1024 parts.
  • IS62WV1024-15T --: Same manufacturer low-power 64K x 16 SRAM family with matching 15 ns timing, offering a familiar supply chain and similar electrical characteristics.
  • IS61LV1024-15T --: Same 64K x 16 SRAM architecture and 15 ns timing from the original vendor's low-voltage family, providing a close electrical match when the standard 5V version is unavailable.
