Description and Introduction

VERSATILE 10 SEC INSTANT VOICE ROM The IS22C012-P is a SRAM (Static Random Access Memory) chip manufactured by ISSI (Integrated Silicon Solution Inc.). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Type:** Asynchronous SRAM  
- **Density:** 128K (128K x 8-bit)  
- **Operating Voltage:** 5V ±10%  
- **Access Time:** 55ns, 70ns, 85ns (depending on variant)  
- **Operating Temperature Range:** Commercial (0°C to +70°C) or Industrial (-40°C to +85°C)  
- **Package:** 28-pin PDIP (Plastic Dual In-line Package)  
- **Interface:** Parallel  
- **Standby Current (Typical):** 10µA (CMOS standby mode)  
- **Active Current (Typical):** 30mA @ 55ns access time  

### **Descriptions:**
- The IS22C012-P is a low-power CMOS SRAM designed for applications requiring moderate-speed memory with low power consumption.  
- It features a fully static operation, meaning no refresh cycles are required.  
- The chip is compatible with industry-standard 128K x 8 SRAMs.  

### **Features:**
- **Low Power Consumption:** CMOS technology ensures reduced power usage in both active and standby modes.  
- **Wide Voltage Range:** Operates at 5V with a tolerance of ±10%.  
- **High-Speed Access:** Available in 55ns, 70ns, and 85ns access time variants.  
- **Easy Interface:** Simple parallel interface compatible with most microcontrollers and processors.  
- **Industrial Grade Option:** Available in an extended temperature range for harsh environments.  
- **Data Retention:** Guaranteed data retention in standby mode with minimal power draw.  

This information is based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

VERSATILE 10 SEC INSTANT VOICE ROM

Alternative Part Number

  • AT27C010-70PU --: 1 Mbit OTP EPROM in DIP-32, functionally similar to the IS22C012 voice ROM and widely available from a different vendor.
  • W27C512-45Z --: 512 Kbit EPROM in DIP-28 with similar parallel interface; suitable drop-in for smaller voice data images.
  • M27C512-10F1 --: 512 Kbit UV EPROM in DIP-28, a common legacy replacement when the full 1 Mbit density is not required.
  • W27C010-70Z --: 1 Mbit CMOS EPROM with compatible pinout and access time, suitable as a drop-in replacement in most legacy designs.
  • M27C1001-70B6 --: 1 Mbit UV EPROM with standard 32-pin DIP pinout, a common second-source option for this memory class.
