71V3577S80PFG8

Overview

The 71V3577S80PFG8 is a synchronous single data rate static random-access memory integrated circuit manufactured by Renesas Electronics Corporation. It features a storage capacity of 4.5 megabits organized as 128K words by 36 bits. The device supports a maximum clock frequency of 100 MHz with an access time of 8 nanoseconds. It operates on a 3.3-volt power supply within a range of 3.135 to 3.465 volts and functions at temperatures between 0°C and 70°C. The component utilizes a parallel interface and is housed in a 100-pin thin quad flat package.
