- **Data Retention Voltage:** 2V (min)  
- **Pin Configuration:** Compatible with industry-standard 128K x 8 SRAMs  

### **Descriptions:**  
- The TC551001CPI-85L is a high-speed, low-power CMOS SRAM designed for applications requiring fast access times and low power consumption.  
- It features a fully static operation, meaning no clock or refresh is required.  
- The device is compatible with TTL levels for easy interfacing with microprocessors.  

### **Features:**  
- **High-Speed Access:** 85 ns maximum access time.  
- **Low Power Consumption:**  
  - Active current: 40 mA (max)  
  - Standby current: 10 µA (max)  
- **Wide Voltage Range:** Operates at 5V ±10%.  
- **Fully Static Operation:** No refresh cycles needed.  
- **TTL-Compatible Inputs/Outputs:** Ensures easy integration with standard logic circuits.  
- **Data Retention Mode:** Maintains data with as low as 2V power supply.  
- **Industry-Standard Pinout:** Compatible with other 128K x 8 SRAMs.  

This information is based on the manufacturer's datasheet for the TC551001CPI-85L.

Application Scenarios & Design Considerations

131,072 WORD x 8 BIT STATIC RAM

Alternative Part Number

  • IS61C1024AL-15T --: 128K x 8 asynchronous SRAM with comparable access time and pinout, widely available and a common drop-in replacement for Toshiba 1Mbit SRAMs.
  • CY7C109B-15ZXC --: 128K x 8 low-power SRAM with similar speed grade and 5V interface, well-established alternative for TC551001 series parts.
  • AS6C1008-55PCN --: 1Mbit (128K x 8) low-power CMOS SRAM designed as a direct replacement for legacy Toshiba SRAMs, with compatible pinout and timing.
  • CY7C1021CV33-15ZXC --: 1Mbit (64K x 16) low-power SRAM with comparable speed grade and 5V/3.3V options; well-documented alternative for legacy Toshiba SRAM designs.
