Description and Introduction

262,144-WORD BY 16 BIT STATIC RAM The TC554161FTL-85L is a 4Mbit (512K x 8) CMOS static RAM (SRAM) manufactured by Toshiba.  

### **Key Specifications:**  
- **Organization:** 512K words × 8 bits  
- **Operating Voltage:** 5V ±10%  
- **Access Time:** 85ns  
- **Operating Temperature Range:** Commercial (0°C to +70°C)  
- **Package:** 32-pin TSOP (Thin Small Outline Package)  
- **Low Power Consumption:**  
  - Active Current: 70mA (max)  
  - Standby Current: 10mA (max) in CMOS mode  
- **Tri-State Outputs** for bus compatibility  
- **Fully Static Operation** (no clock or refresh required)  
- **Data Retention Voltage:** 2V (min)  

### **Features:**  
- **High-Speed Performance** with 85ns access time  
- **CMOS Technology** for low power consumption  
- **Wide Operating Voltage Range** (4.5V to 5.5V)  
- **Easy Memory Expansion** using chip enable (CE) and output enable (OE) controls

Alternative Part Number

  • IS61LV25616AL-10TL --: 256K x 16 asynchronous SRAM with similar 70-100ns speed grade and 44-pin TSOP package, widely available and pin-compatible in most designs.
  • CY7C1041CV33-10ZXI --: 256K x 16 low-power SRAM in 44-pin TSOP II, comparable access time and 3.3V operation, a common drop-in replacement for Toshiba SRAMs.
  • AS6C4008-55TIN --: 512K x 8 SRAM offering similar asynchronous interface and speed, suitable when a slightly different organization can be accommodated; Alliance specializes in legacy SRAM replacements.
