Description and Introduction

524,288-WORD BY 8-BIT STATIC RAM The TC554001AFT-85L is a SRAM (Static Random Access Memory) chip manufactured by Toshiba. Below are the key specifications, descriptions, and features based on available information:

### **Specifications:**  
- **Memory Type:** Static RAM (SRAM)  
- **Density:** 4 Mbit (512K × 8-bit organization)  
- **Supply Voltage:** 5V ±10%  
- **Access Time:** 85 ns  
- **Operating Temperature Range:** Commercial (0°C to +70°C) or Industrial (-40°C to +85°C)  
- **Package Type:** 32-pin TSOP (Thin Small Outline Package)  
- **Interface:** Parallel  
- **Standby Current:** Low power consumption in standby mode  

### **Descriptions:**  
- The TC554001AFT-85L is a high-speed CMOS static RAM designed for applications requiring fast access times and low power consumption.  
- It features a fully static operation, meaning no refresh cycles are required.  
- The 8-bit wide data bus makes it suitable for microprocessor-based systems.  

### **Features:**  
- **High-Speed Access:** 85 ns access time for efficient performance.  
- **Low Power Consumption:** CMOS technology ensures reduced power usage.  
- **Wide Operating Voltage:** Supports 5V ±10% for stable operation.  
- **Easy Integration:** Compatible with standard microprocessor interfaces.  
- **Reliable Data Retention:** Ensures data integrity without refresh cycles.  

This SRAM is commonly used in embedded systems, industrial controls, networking equipment, and other applications requiring fast, non-volatile memory.  

(Note: For the most accurate and updated details, always refer to the official Toshiba datasheet.)

Application Scenarios & Design Considerations

524,288-WORD BY 8-BIT STATIC RAM

Alternative Part Number

  • IS61C5128AL-10TLI --: 512K x 8 asynchronous SRAM with similar 5V-tolerant interface and access time, direct functional replacement for the 4Mbit SRAM.
  • CY7C1041CV33-10ZXI --: 4Mbit asynchronous SRAM in TSOP package with comparable speed grade, widely used as a drop-in alternative for Toshiba SRAMs.
  • AS6C4008-55TIN --: 4Mbit low-power CMOS SRAM pin-compatible with common 512K x 8 SRAMs, suitable replacement when 85ns timing is acceptable.
