Description and Introduction

SILICON GATE CMOS 32,768 WORD x 8 BIT STATIC RAM The TC55257CFI-85L is a 262,144-bit high-speed static random access memory (SRAM) manufactured by Toshiba. Below are its specifications, descriptions, and features:

### **Specifications:**
- **Organization:** 32K words × 8 bits  
- **Operating Voltage:** 5V ±10%  
- **Access Time:** 85 ns  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-pin Plastic SOP (Small Outline Package)  
- **Standby Current (TTL Level):** 10 µA (max)  
- **Operating Current:** 40 mA (max)  
- **Data Retention Voltage:** 2V (min)  
- **Pin Configuration:** Compatible with other 32K × 8 SRAMs  

### **Descriptions:**
- The TC55257CFI-85L is a low-power CMOS SRAM designed for high-speed applications.  
- It features a fully static operation, meaning no clock or refresh is required.  
- The memory is suitable for battery-backed or low-power systems due to its low standby current.  
- It is commonly used in embedded systems, industrial controls, and communication devices.  

### **Features:**
- **High-Speed Access:** 85 ns access time for fast read/write operations.  
- **Low Power Consumption:** CMOS technology ensures low active and standby power.  
- **Wide Operating Temperature:** Supports industrial-grade temperature ranges (-40°C to +85°C).  
- **TTL-Compatible Inputs/Outputs:** Ensures compatibility with standard logic levels.  
- **Single 5V Power Supply:** Simplifies system design.  
- **Tri-State Outputs:** Allows direct connection to a common bus.  

This information is based on Toshiba's official documentation for the TC55257CFI-85L SRAM.
