Description and Introduction

524,288-WORD BY 8-BIT STATIC RAM The TC554001AFT-70L is a SRAM (Static Random Access Memory) chip manufactured by Toshiba. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Memory Type:** Static RAM (SRAM)  
- **Organization:** 512K x 8 (4 Mbit)  
- **Supply Voltage:** 5V ±10%  
- **Access Time:** 70 ns  
- **Operating Temperature Range:** Commercial (0°C to +70°C)  
- **Package Type:** 32-pin TSOP (Thin Small Outline Package)  
- **Pin Count:** 32  
- **Interface:** Parallel  

### **Descriptions:**  
- The TC554001AFT-70L is a high-speed CMOS SRAM designed for applications requiring fast access times.  
- It features a fully static operation, meaning no refresh cycles are required.  
- The chip is compatible with TTL levels for easy interfacing with microprocessors.  

### **Features:**  
- **Low Power Consumption:** CMOS technology ensures low power operation.  
- **High-Speed Access:** 70 ns access time for fast data retrieval.  
- **Wide Voltage Range:** Operates at 5V ±10%.  
- **Fully Static Operation:** No clock or refresh needed.  
- **TTL-Compatible Inputs/Outputs:** Ensures compatibility with standard logic levels.  
- **Industrial Standard Pinout:** Matches industry-standard SRAM configurations.  

This information is based solely on the provided knowledge base. Let me know if you need further details.

Alternative Part Number

  • IS61C1024AL-70T --: 128K x 8 asynchronous SRAM with 70 ns access time, functionally equivalent to the TC554001AFT-70L and widely available.
  • CY7C1021DV33-10ZSXI --: 64K x 16 high-speed CMOS SRAM with similar organization and 5 V/3.3 V options; a common drop-in alternative for Toshiba SRAM parts.
  • AS6C1008-55TIN --: 128K x 8 low-power CMOS SRAM with 55 ns access time, pin-compatible with many 128K x 8 SRAM devices and a good second source.
  • CY7C1021CV33-70ZXC --: 1M-bit (128K x 8) fast SRAM with 70 ns speed grade, drop-in compatible pinout and timing for the original Toshiba part.
  • AS7C31026C-70TCN --: 128K x 8 SRAM with 70 ns access time, offered as a direct replacement for legacy Toshiba SRAMs with matching package and interface.
