- **Standby Current:** 10μA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 32-pin TSOP (Thin Small Outline Package)  

### **Descriptions:**
- **Type:** Low-power CMOS SRAM  
- **Function:** High-speed, fully static operation with no clock or refresh required  
- **Interface:** Parallel (8-bit data bus)  
- **Applications:** Embedded systems, networking equipment, industrial controls, and consumer electronics  

### **Features:**
- **Low Power Consumption:** Optimized for battery-operated and power-sensitive applications.  
- **High-Speed Operation:** 70ns access time for efficient performance.  
- **Wide Voltage Range:** Supports 3.3V ± 0.3V operation.  
- **Fully Static Design:** No refresh cycles required.  
- **TTL-Compatible Inputs/Outputs:** Ensures easy interfacing with other logic circuits.  
- **Data Retention:** Guaranteed in standby mode with minimal power consumption.  
- **Lead-Free & RoHS Compliant:** Meets environmental standards.  

This SRAM is designed for applications requiring reliable, non-volatile memory with fast access times and low power consumption.

Alternative Part Number

  • IS61C1024AL-70TLI --: 1Mbit (128K x 8) asynchronous SRAM with 70 ns access time, functionally equivalent to the TC554001FL-70L and widely available.
  • CY7C1021CV33-70ZXC --: 1Mbit (64K x 16) fast asynchronous SRAM with 70 ns speed grade, suitable replacement for the same memory density and timing class.
  • AS6C1008-55TIN --: 1Mbit (128K x 8) low-power CMOS SRAM with 55 ns access time, a common drop-in alternative for Toshiba 1Mbit SRAM parts.
  • CY7C1019DV33-10ZSXI --: 128K x 8 low-power SRAM in the same density class; 10 ns speed grade exceeds the 70 ns requirement, making it a safe drop-in for most designs.
  • IS61C1024AL-70T --: 128K x 8 asynchronous SRAM with 70 ns access time, functionally equivalent to the TC554001FL-70L and widely available.
