Description and Introduction

32K X 8 LOW POWER CMOS STATIC RAM The part **T15M256A-70D** is manufactured by **TM (Toshiba Memory, now Kioxia)**. Below are the factual specifications, descriptions, and features based on available knowledge:  

### **Specifications:**  
- **Memory Type:** SRAM (Static Random-Access Memory)  
- **Density:** 256Kb (32K x 8-bit)  
- **Speed:** 70ns access time  
- **Voltage:** 5V (TTL-compatible)  
- **Package:** 28-pin DIP (Dual In-line Package)  
- **Operating Temperature:** Commercial (0°C to +70°C) or Industrial (-40°C to +85°C) depending on variant  
- **Organization:** Asynchronous SRAM  

### **Descriptions & Features:**  
- **High-Speed Operation:** 70ns access time suitable for embedded and industrial applications.  
- **Low Power Consumption:** CMOS technology for reduced power usage.  
- **Wide Voltage Compatibility:** 5V operation with TTL-compatible I/O.  
- **Reliable Data Retention:** Ensures stable performance in volatile memory applications.  
- **Standard Pinout:** 28-pin DIP package for easy integration into legacy systems.  
- **Asynchronous Operation:** No clock signal required, simplifying interface design.  

This part was commonly used in older computing systems, telecommunications, and industrial control applications. For exact datasheet details, refer to **TM (Toshiba Memory/Kioxia)** documentation.

Application Scenarios & Design Considerations

32K X 8 LOW POWER CMOS STATIC RAM

Alternative Part Number

  • IS61C256AH-70T --: 32K x 8 high-speed CMOS SRAM with 70 ns access time in a TSOP package, functionally equivalent to the T15M256A-70D and widely available.
  • CY62256NLL-70ZXI --: 32K x 8 low-power SRAM with 70 ns speed grade, pin-compatible with standard 256K SRAM devices and a common drop-in replacement.
  • AS6C2568-55TIN --: 32K x 8 low-power CMOS SRAM in TSOP with 55 ns access time, faster than the original 70 ns requirement and suitable as a direct substitute.
  • IS61C256AL-70T --: 32K x 8 asynchronous SRAM with 70 ns access time, functionally equivalent to the T15M256A-70D and widely available.
  • AS6C62256-70PCN --: 32K x 8 SRAM with 70 ns access time, direct drop-in alternative for legacy 62256-type devices.
  • CY62256-70PC --: 32K x 8 low-power SRAM with 70 ns speed grade, functionally equivalent and a common drop-in replacement for 256K-bit SRAMs.
