Description and Introduction

256K x 16 (4-MBIT) DYNAMIC RAM WITH EDO PAGE MODE The IS41C16256-35T is a high-speed CMOS static RAM (SRAM) manufactured by Integrated Silicon Solution Inc. (ISSI). Here are the key specifications, descriptions, and features:

### **Specifications:**  
- **Density:** 256K (32K x 8)  
- **Speed:** 35 ns access time  
- **Voltage Supply:** 5V ±10%  
- **Operating Current:** 70 mA (typical)  
- **Standby Current:** 10 mA (typical) in CMOS mode, 30 mA (typical) in TTL mode  
- **Package:** 28-pin TSOP (Thin Small Outline Package)  
- **Operating Temperature Range:** Commercial (0°C to +70°C)  

### **Description:**  
The IS41C16256-35T is a low-power, high-performance SRAM designed for applications requiring fast access times and low power consumption. It is commonly used in embedded systems, networking equipment, and industrial applications.  

### **Features:**  
- **High-Speed Performance:** 35 ns access time  
- **Low Power Consumption:** CMOS standby mode reduces power usage  
- **TTL-Compatible Inputs/Outputs:** Ensures compatibility with standard logic levels  
- **Fully Static Operation:** No clock or refresh required  
- **Three-State Outputs:** Allows bus sharing in multi-memory systems  
- **Industrial Standard Pinout:** Compatible with other 32K x 8 SRAMs  

This information is based solely on the manufacturer's datasheet.

Application Scenarios & Design Considerations

256K x 16 (4-MBIT) DYNAMIC RAM WITH EDO PAGE MODE

Alternative Part Number

  • AS4C256K16E0-35TC --: Alliance Memory specializes in drop-in replacements for legacy ISSI SRAM/DRAM parts; this 256Kx16 asynchronous DRAM matches the 35 ns speed grade and TSOP package, making it the closest functional substitute.
  • CY7C1041CV33-35ZC --: Cypress 256Kx16 asynchronous SRAM with 35 ns access time offers comparable density, speed, and pinout compatibility for designs originally using the IS41C16256.
  • IS61WV25616EDBLL-35TLI --: ISSI's own 256Kx16 high-speed asynchronous SRAM in the same 35 ns speed bin provides a same-vendor migration path with similar timing and interface characteristics.
