Description and Introduction

524,288-WORD BY 8-BIT STATIC RAM The part **TC554001AF-70L** is manufactured by **Toshiba (TOS)**. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Memory Type:** SRAM (Static Random-Access Memory)  
- **Density:** 4 Mbit (512K x 8)  
- **Speed:** 70 ns  
- **Voltage Supply:** 5V  
- **Operating Temperature:** Commercial (0°C to +70°C)  
- **Package:** 32-pin SOJ (Small Outline J-Lead)  

### **Descriptions:**  
- The **TC554001AF-70L** is a high-speed CMOS static RAM designed for applications requiring fast access times.  
- It features a common I/O structure, reducing pin count and simplifying system design.  
- The device is compatible with TTL levels and supports asynchronous operation.  

### **Features:**  
- **Low Power Consumption:** CMOS technology ensures efficient power usage.  
- **High-Speed Access:** 70 ns access time for fast read/write operations.  
- **Single 5V Supply:** Simplifies power management in embedded systems.  
- **TTL-Compatible Inputs/Outputs:** Ensures compatibility with standard logic levels.  
- **Battery Backup Capability:** Supports data retention in low-power modes.  

This information is based solely on the available technical data for the **TC554001AF-70L** from Toshiba.

Alternative Part Number

  • IS61C1024AL-70TLI --: 128K x 8 asynchronous SRAM with 70 ns access time, functionally equivalent to the TC554001AF-70L and widely available as a drop-in replacement.
  • CY7C1021DV33-10ZSXI --: 64K x 16 or 128K x 8 SRAM family with comparable speed grade and 5V/3.3V options; commonly used as an alternative to Toshiba 128K x 8 SRAMs.
  • AS6C1008-55TIN --: Low-power 128K x 8 CMOS SRAM with 55 ns access time, pin-compatible with standard 128K x 8 SRAM devices and suitable as a replacement for the TC554001AF-70L.
  • CY7C1019DV33-10ZSXI --: 128K x 8 low-power SRAM in a similar package with comparable access time, suitable as a drop-in replacement in most designs.
  • IS61C1024AL-70T --: 128K x 8 asynchronous SRAM with 70 ns access time, functionally equivalent to the TC554001AF-70L and widely available.
  • CY7C1021CV33-70ZXC --: 64K x 16 fast SRAM with 70 ns speed grade, comparable pinout and timing suitable as a drop-in replacement.
  • AS7C1024B-70TC --: 128K x 8 low-power CMOS SRAM at 70 ns, direct functional substitute for the Toshiba part with similar package options.
