Description and Introduction

SILICON GATE CMOS 32,768 WORD x 8 BIT STATIC RAM The **TC55257CSPI-85L** is a **32K x 8-bit CMOS Static RAM (SRAM)** manufactured by **Toshiba**.  

### **Key Specifications:**  
- **Organization:** 32K × 8 bits  
- **Technology:** CMOS  
- **Supply Voltage:** 5V ± 10%  
- **Access Time:** 85 ns  
- **Operating Current:** 30 mA (max)  
- **Standby Current:** 10 μA (max)  
- **Package:** **CSPI** (Chip Scale Package)  
- **Operating Temperature Range:** Commercial (0°C to +70°C)  

### **Features:**  
- **Low Power Consumption** (both active and standby modes)  
- **Fully Static Operation** (no refresh required)  
- **TTL-Compatible Inputs/Outputs**  
- **Single 5V Power Supply**  
- **High Reliability** (CMOS technology)  

This SRAM is designed for applications requiring **fast access times and low power consumption**, such as embedded systems, industrial controls, and consumer electronics.  

(Note: The **CSPI** package indicates a **Chip Scale Package**, which is compact and suitable for space-constrained designs.)

Application Scenarios & Design Considerations

SILICON GATE CMOS 32,768 WORD x 8 BIT STATIC RAM

Alternative Part Number

  • IS62C256AL-45ULI --: 32K x 8 low-power CMOS SRAM with similar 85 ns class access time and pin-compatible DIP/SOP footprint, widely available as a drop-in replacement.
  • AS6C62256-55SIN --: 32K x 8 asynchronous SRAM in the same density and organization, 55 ns speed grade covers the 85 ns requirement, and Alliance is a common second source for legacy Toshiba SRAMs.
  • CY62256NLL-70SNXI --: 32K x 8 low-power SRAM with 70 ns access time that meets or exceeds the original 85 ns spec, available in compatible SOIC packages for legacy designs.
