Description and Introduction

128K x 16 Hight Speed SRAM with 3.3V The IC61LV12816-12B is a 128K x 16-bit (2 Mbit) high-speed CMOS Static RAM (SRAM) manufactured by ISSI (Integrated Silicon Solution, Inc.). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Organization:** 128K x 16-bit (2 Mbit)  
- **Supply Voltage:** 3.3V (±10%)  
- **Access Time:** 12 ns  
- **Operating Current:** 80 mA (typical)  
- **Standby Current:** 10 µA (typical)  
- **Operating Temperature Range:** Commercial (0°C to +70°C) or Industrial (-40°C to +85°C)  
- **Package Type:** 44-pin TSOP II (Type II)  

### **Descriptions:**
- The IC61LV12816-12B is a high-performance, low-power SRAM designed for applications requiring fast access times and low power consumption.  
- It is compatible with 3.3V systems and features a fully static memory cell design, eliminating the need for external refresh.  
- The device supports asynchronous operation with separate byte controls (UB, LB) for flexible read/write operations.  

### **Features:**
- **High-Speed Performance:** 12 ns access time.  
- **Low Power Consumption:**  
  - Active current: 80 mA (typical).  
  - Standby current: 10 µA (typical).  
- **3.3V Single Power Supply.**  
- **Fully Static Operation:** No clock or refresh required.  
- **Byte Control:** Supports upper byte (UB) and lower byte (LB) control.  
- **TTL-Compatible Inputs and Outputs.**  
- **Industrial Temperature Support (-40°C to +85°C).**  
- **Lead-Free and RoHS Compliant.**  

This SRAM is commonly used in networking, telecommunications, embedded systems, and other high-speed memory applications.

Application Scenarios & Design Considerations

128K x 16 Hight Speed SRAM with 3.3V

Alternative Part Number

  • IS61LV12816-12T --: Same 128Kx16 low-voltage asynchronous SRAM with 12 ns access time from the original ISSI family, pin-compatible and functionally equivalent.
  • CY7C1041DV33-12ZSXIT --: 256Kx16 low-voltage SRAM with 12 ns speed; can replace the 128Kx16 device in many designs with the same interface and supply voltage.
  • AS7C34098A-12TCN --: Low-power 256Kx16 asynchronous SRAM with 12 ns access time, widely used as a drop-in alternative for ISSI 12816-type SRAMs.
  • IS62WV12816BLL-55TLI --: Same manufacturer 128Kx16 asynchronous SRAM family with comparable speed grade and pinout, widely available and often used as a drop-in replacement.
  • CY7C1041CV33-12ZSXET --: 256Kx16 fast asynchronous SRAM with 12 ns access time, similar interface and voltage, suitable functional substitute when density margin is acceptable.
