Description and Introduction

MOS DIGITAL INTEGRATED CIRCUIT The TC55257DTRL-70V is a 262,144-bit high-speed CMOS static RAM (SRAM) manufactured by Toshiba.  

### **Specifications:**  
- **Organization:** 32K words × 8 bits  
- **Operating Voltage:** 4.5V to 5.5V  
- **Access Time:** 70 ns  
- **Operating Current:** 40 mA (max)  
- **Standby Current:** 10 µA (max)  
- **Package:** 28-pin SOP (Small Outline Package)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Pin Configuration:** Compatible with industry-standard 32K × 8 SRAMs  

### **Descriptions and Features:**  
- **High-Speed Operation:** 70 ns access time  
- **Low Power Consumption:** CMOS technology ensures low standby current  
- **Wide Voltage Range:** Operates from 4.5V to 5.5V  
- **Fully Static Operation:** No clock or refresh required  
- **Tri-State Output:** Allows bus-oriented applications  
- **TTL-Compatible Inputs/Outputs:** Ensures easy interfacing with TTL logic  
- **Data Retention:** Guaranteed in standby mode with reduced voltage (2V min)  

This SRAM is suitable for applications requiring high-speed, low-power memory, such as embedded systems, industrial controls, and telecommunications equipment.  

(Note: Always verify datasheets for the latest specifications.)

Application Scenarios & Design Considerations

MOS DIGITAL INTEGRATED CIRCUIT

Alternative Part Number

  • IS62C256AL-70U --: 32K x 8 low-power CMOS SRAM with 70 ns access time, pin-compatible with the TC55257 series and widely available.
  • AS6C62256-70PCN --: 32K x 8 asynchronous SRAM, 70 ns speed grade, direct functional replacement for 55257-type low-power SRAMs.
  • CY62256NLL-70PXC --: 32K x 8 low-power SRAM with 70 ns access time, same JEDEC pinout and comparable standby current.
