Description and Introduction

262,144-WORD BY 16-BIT STATIC RAM The TC554161AFT-70L is a 4Mbit (512K x 8) high-speed CMOS static RAM (SRAM) manufactured by Toshiba. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Organization:** 512K words × 8 bits  
- **Operating Voltage:** 5V ±10%  
- **Access Time:** 70ns (max)  
- **Operating Current:** 80mA (max)  
- **Standby Current:** 10μA (max)  
- **Package:** 32-pin TSOP (Thin Small Outline Package)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Data Retention Voltage:** 2V (min)  

### **Descriptions:**
- The TC554161AFT-70L is a high-performance CMOS SRAM designed for applications requiring fast access times and low power consumption.  
- It is compatible with TTL levels and features a fully static operation, eliminating the need for external refresh.  
- The device is suitable for battery-backed or low-power systems due to its low standby current.  

### **Features:**
- **High-Speed Access:** 70ns maximum access time.  
- **Low Power Consumption:**  
  - Active current: 80mA (max)  
  - Standby current: 10μA (max)  
- **Wide Operating Voltage Range:** 4.5V to 5.5V.  
- **Fully Static Operation:** No clock or refresh required.  
- **TTL-Compatible Inputs/Outputs.**  
- **Tri-State Outputs:** Allows bus sharing in multi-master systems.  
- **Data Retention at Low Voltage:** Maintains data with a minimum of 2V.  

This SRAM is commonly used in industrial, automotive, and consumer electronics applications where fast and reliable memory access is required.
