Description and Introduction

-0.3 to 7V; 1W; 150ns; 8.192 word x 8bit MOS static RAM The TC5564APL-15 is a high-speed static RAM (SRAM) manufactured by Toshiba. Below are the specifications, descriptions, and features based on the available knowledge:

### **Specifications:**  
- **Type:** High-Speed CMOS Static RAM (SRAM)  
- **Organization:** 8K x 8-bit (65,536 bits)  
- **Supply Voltage:** 5V ±10%  
- **Access Time:** 15 ns (max)  
- **Operating Temperature Range:** 0°C to +70°C (Commercial)  
- **Package:** 28-pin Plastic DIP (Dual In-line Package)  
- **Power Consumption:**  
  - Active: 275 mW (typical)  
  - Standby: 27.5 mW (typical)  

### **Descriptions:**  
- The TC5564APL-15 is a low-power, high-performance SRAM designed for applications requiring fast access times.  
- It is compatible with TTL levels and features a fully static operation, meaning no clock or refresh is required.  
- Suitable for cache memory, buffer storage, and other high-speed memory applications.  

### **Features:**  
- **High-Speed Access:** 15 ns maximum access time.  
- **Low Power Consumption:** CMOS technology ensures reduced power usage in both active and standby modes.  
- **Wide Operating Voltage Range:** 4.5V to 5.5V.  
- **TTL-Compatible Inputs/Outputs:** Ensures easy interfacing with TTL logic circuits.  
- **Fully Static Operation:** No refresh cycles required.  
- **Tri-State Outputs:** Allows direct connection to a common bus.  
- **Single 5V Power Supply:** Simplifies system design.  

This information is based on Toshiba's datasheet for the TC5564APL-15 SRAM. For detailed electrical characteristics and timing diagrams, refer to the official documentation.

Application Scenarios & Design Considerations

-0.3 to 7V; 1W; 150ns; 8.192 word x 8bit MOS static RAM

Alternative Part Number

  • CY7C199-15PC --: 15ns 32Kx8 asynchronous SRAM in a 28-pin DIP, functionally equivalent to the TC5564APL-15 with similar access time and pinout.
  • IS61C256AH-15N --: 32Kx8 high-speed SRAM with 15ns access time in a 28-pin DIP package, a direct drop-in replacement for the Toshiba part.
  • AS7C256-15PC --: 32Kx8 15ns SRAM in a 28-pin DIP, pin-compatible and timing-compatible alternative suitable for legacy designs.
  • HM62256BLP-15 --: 32K x 8 low-power CMOS SRAM with 15 ns access time in a 28-pin DIP, a common drop-in replacement for the TC5564 series.
  • AS6C62256-55PCN --: 32K x 8 low-power SRAM in a 28-pin DIP with pinout compatible with the TC5564APL; the 55 ns version is slower but widely available and suitable for non-critical timing designs.
  • AS7C256A-15PCN --: 32Kx8 15 ns SRAM in 28-pin DIP, drop-in compatible timing and interface, good long-term availability option.
  • HM628128LP-15 --: 128K x 8 SRAM with 15 ns access time in a DIP package, suitable as a drop-in replacement for the TC5564APL-15.
