Description and Introduction

256K Bit Mask ROM The part **TMM23256P** is manufactured by **TOS (Toshiba)**. Below are the specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** TOS (Toshiba)  
- **Part Number:** TMM23256P  
- **Type:** SRAM (Static Random Access Memory)  
- **Density:** 32K (32,768 words x 8 bits)  
- **Voltage Supply:** 5V  
- **Access Time:** Typically 100ns (may vary by variant)  
- **Package:** DIP (Dual In-line Package), likely 28-pin  
- **Operating Temperature:** Commercial (0°C to 70°C) or Industrial (-40°C to 85°C) depending on variant  

### **Descriptions:**
- The **TMM23256P** is a **32K x 8-bit CMOS SRAM** designed for high-speed, low-power applications.  
- It is commonly used in embedded systems, industrial controls, and legacy computing applications.  
- Features a **non-volatile** (static) memory design, meaning it retains data as long as power is supplied.  

### **Features:**
- **Low Power Consumption:** CMOS technology ensures efficient power usage.  
- **High-Speed Operation:** Suitable for systems requiring fast memory access.  
- **Wide Operating Voltage:** Compatible with standard 5V systems.  
- **Simple Interface:** Directly compatible with most microprocessors.  
- **Reliable Data Retention:** Maintains data integrity without refresh cycles.  

For exact timing, pinout, or additional variants, refer to the **TOS (Toshiba) datasheet** for the TMM23256P.
