Description and Introduction

131,072 WORD x 8 BIT STATIC RAM The TC551001CFTI-70 is a 1M-bit (128K x 8-bit) CMOS static RAM (SRAM) manufactured by Toshiba.  

### **Key Specifications:**  
- **Organization:** 128K words × 8 bits  
- **Operating Voltage:** 5V ±10%  
- **Access Time:** 70ns  
- **Operating Current:** 40mA (max)  
- **Standby Current:** 10μA (max)  
- **Package:** 32-pin TSOP (Thin Small Outline Package)  
- **Temperature Range:** Commercial (0°C to +70°C)  

### **Features:**  
- **Low Power Consumption:** CMOS technology ensures low standby current.  
- **Fully Static Operation:** No clock or refresh required.  
- **Tri-State Output:** Allows bus sharing in multi-memory systems.  
- **TTL-Compatible Inputs/Outputs:** Ensures easy interfacing with TTL logic.  
- **Single 5V Power Supply:** Simplifies system design.  

This SRAM is suitable for applications requiring fast, low-power memory, such as embedded systems, networking devices, and industrial controls.

Application Scenarios & Design Considerations

131,072 WORD x 8 BIT STATIC RAM

Alternative Part Number

  • IS61C1024AL-70TI --: 128K x 8 asynchronous SRAM with 70 ns access time in a TSOP package, functionally equivalent to the TC551001 series and widely available.
  • CY7C109B-70ZXC --: 128K x 8 low-power CMOS SRAM with 70 ns speed grade, pin-compatible with the TC551001 and a common drop-in replacement.
  • AS6C1008-55TIN --: 128K x 8 low-power SRAM in TSOP with 55 ns access time, faster than the original 70 ns and a direct functional substitute.
