Description and Introduction

128K x 8 LOW POWER CMOS STATIC RAM The IS62C1024L-70Q is a high-speed CMOS static RAM (SRAM) manufactured by ISSI (Integrated Silicon Solution, Inc.). Below are the factual specifications, descriptions, and features of the device:

### **Specifications:**  
- **Organization:** 128K x 8-bit (1Mbit)  
- **Operating Voltage:** 5V ±10%  
- **Access Time:** 70ns  
- **Operating Current:** 40mA (typical)  
- **Standby Current:** 10μA (typical)  
- **Package:** 32-pin PLCC (Plastic Leaded Chip Carrier)  
- **Temperature Range:**  
  - Commercial (0°C to +70°C)  
  - Industrial (-40°C to +85°C)  
- **Pin Configuration:** Compatible with industry-standard 128K x 8 SRAMs  

### **Descriptions:**  
- The IS62C1024L-70Q is a low-power, high-performance SRAM designed for applications requiring fast access times and low power consumption.  
- It features a fully static operation, meaning no refresh cycles are required.  
- The device is suitable for battery-backed or power-sensitive applications due to its low standby current.  

### **Features:**  
- **High-Speed Performance:** 70ns access time  
- **Low Power Consumption:**  
  - Active current: 40mA (typical)  
  - Standby current: 10μA (typical)  
- **Fully Static Operation:** No clock or refresh needed  
- **Tri-State Outputs:** Directly compatible with common bus structures  
- **TTL-Compatible Inputs and Outputs**  
- **Industrial Temperature Support:** Available in extended temperature range (-40°C to +85°C)  
- **Reliable Data Retention:** Ensures stability in power-sensitive applications  

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

Application Scenarios & Design Considerations

128K x 8 LOW POWER CMOS STATIC RAM

Alternative Part Number

  • CY62256NLL-70ZXI --: 32K x 8 low-power SRAM in the same 70 ns speed grade and TSOP package class, widely available and pin-compatible in most 128K x 8 sockets after address decoding review.
  • AS6C62256-55SIN --: Low-power CMOS SRAM with 55 ns access time that exceeds the 70 ns requirement, offered in a compatible TSOP-I package and commonly used as a drop-in replacement for legacy ICSI SRAMs.
  • IS61WV1288EDBLL-10TLI --: 128K x 8 high-speed asynchronous SRAM from a different series than the source, with 10 ns speed and TSOP package, suitable when a faster, currently active equivalent is needed.
  • AS6C1008-55TIN --: 128K x 8 low-power CMOS SRAM offered as a direct functional replacement for IS62C1024 series, with 55 ns access time that meets or beats the 70 ns requirement.
  • LY62L1024LL-70LL --: 128K x 8 low-power SRAM with 70 ns access time, designed as a drop-in alternative to ISSI IS62C1024 parts in the same package and pinout.
  • CY7C1021CV33-10ZXC --: Pin-compatible 1Mbit (64K x 16) asynchronous SRAM with similar access time and 3.3V supply, widely used as a drop-in replacement for the IS62C1024 series.
  • AS6C62256-55PCN --: Alliance Memory specializes in legacy SRAM replacements; this 32K x 8 low-power SRAM matches the IS62C1024 family's interface and timing closely for 5V systems.
  • IS61WV102416BLL-10TLI --: ISSI 1Mbit (64K x 16) high-speed asynchronous SRAM with compatible pinout and voltage, offering a direct functional substitute for the Hynix part.
  • AS6C1008-55PCN --: Alliance Memory specializes in legacy SRAM replacements; AS6C1008 is a 1Mbit (128K x 8) 5V asynchronous SRAM functionally equivalent to IS62C1024 with comparable speed grades.
  • HM628128ALP-70 --: 1Mbit (128K x 8) 5V low-power CMOS SRAM with 70ns access time in the same DIP/TSOP footprint family, a well-established alternative to the ISSI 62C1024L.
