Additional Details

The TC551001CSTI-85L operates with a single 5V power supply. The SRAM features separate data input and output pins, allowing for easy interfacing with microprocessors and other digital circuits. The chip enable (CE) and output enable (OE) pins provide control over memory access. The write enable (WE) pin controls the write operation. The SRAM is typically available in a DIP (Dual In-line Package) or SOJ (Small Outline J-lead) package. The datasheet provides detailed information on timing characteristics, power consumption, and operating conditions. Proper decoupling capacitors are essential for stable operation.
