Description and Introduction

SILICON GATE CMOS 131,072 WORD x 8 BIT STATIC RAM The TC551001BFL-70L is a 1Mbit (128K x 8) CMOS static RAM (SRAM) manufactured by Toshiba. Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Organization:** 128K words × 8 bits  
- **Operating Voltage:** 5V ±10%  
- **Access Time:** 70ns  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 32-pin SOP (Small Outline Package)  
- **Power Consumption:**  
  - Active: 100mA (max)  
  - Standby: 10μA (max)  

### **Descriptions & Features:**  
- **High-Speed Operation:** 70ns access time for fast read/write operations.  
- **Low Power Consumption:** Features both active and standby modes for power efficiency.  
- **CMOS Technology:** Ensures low power dissipation and high noise immunity.  
- **Fully Static Operation:** No refresh cycles required.  
- **TTL-Compatible Inputs/Outputs:** Ensures compatibility with TTL logic levels.  
- **Tri-State Outputs:** Allows bus sharing in multi-memory systems.  
- **Single 5V Power Supply:** Simplifies system design.  
- **Wide Operating Temperature Range:** Suitable for commercial applications.  

This SRAM is commonly used in applications requiring fast, low-power, and reliable memory, such as embedded systems, networking devices, and industrial controls.

Application Scenarios & Design Considerations

SILICON GATE CMOS 131,072 WORD x 8 BIT STATIC RAM

Alternative Part Number

  • IS61C1024AL-70TLI --: 128K x 8 asynchronous SRAM with 70 ns access time, functionally equivalent to the TC551001BFL-70L and widely available.
  • CY7C1019DV33-10ZSXI --: 128K x 8 low-power SRAM in the same density class with comparable speed grade, suitable as a direct drop-in alternative.
  • AS6C1008-55TIN --: 128K x 8 low-power CMOS SRAM with 55 ns access time, pin-compatible replacement for the Toshiba TC551001BFL series.
  • CY62128EV30LL-45ZXI --: 128K x 8 low-power SRAM with 45 ns access time, faster than the original 70 ns part and suitable as a functional substitute.
