Description and Introduction

131,072 WORD x 8 BIT STATIC RAM The TC551001CFTI-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 Current:** 40mA (max)  
- **Standby Current:** 10μA (max, CMOS level)  
- **Package:** 32-pin TSOP (Thin Small Outline Package)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
- The TC551001CFTI-70L is a high-speed, low-power SRAM designed for applications requiring fast access times and battery backup operation.  
- It is fabricated using Toshiba's advanced CMOS technology, ensuring low power consumption while maintaining high performance.  
- The device is compatible with TTL levels for easy interfacing with microprocessors and other logic circuits.  

### **Features:**
- **Low Power Consumption:**  
  - Active current: 40mA (max)  
  - Standby current: 10μA (max, CMOS level)  
- **High-Speed Access:** 70ns access time  
- **Wide Operating Voltage Range:** 4.5V to 5.5V  
- **Fully Static Operation:** No clock or refresh required  
- **TTL-Compatible Inputs/Outputs**  
- **Single 5V Power Supply**  
- **Three-State Outputs**  
- **Battery Backup Capable**  

This SRAM is commonly used in industrial, automotive, and consumer electronics applications where fast and reliable memory access is required.

Application Scenarios & Design Considerations

131,072 WORD x 8 BIT STATIC RAM

Alternative Part Number

  • IS61C1024AL-70TI --: 1Mbit (128K x 8) low-power CMOS SRAM in TSOP package with 70ns access time, functionally equivalent to the TC551001 series and widely available.
  • AS6C1008-55TIN --: 128K x 8 low-power SRAM with 55ns access time (faster than 70ns), TSOP package, direct drop-in replacement for 1Mbit asynchronous SRAMs.
  • CY62128EV30LL-45ZXI --: 1Mbit (128K x 8) low-power SRAM with 45ns access time in TSOP, compatible pinout and voltage range for the TC551001CFTI application.
  • IS61C1024AL-70TLI --: 128K x 8 low-power CMOS SRAM with 70 ns access time in TSOP package, functionally equivalent to the original 1M-bit SRAM.
  • CY7C1019DV33-10ZSXI --: 128K x 8 asynchronous SRAM with comparable speed grade and TSOP footprint, widely used as a drop-in replacement for Toshiba 1M-bit SRAMs.
