7142LA35CB

Overview

The Renesas Electronics Corporation 7142LA35CB is a static random-access memory (SRAM) device belonging to the 7142SA/LA series. It features an 8K-bit capacity organized as 1K words by 8 bits. The component utilizes CMOS dual-port technology with asynchronous parallel interfaces for independent read and write operations. It operates within a supply voltage range of 4.5V to 5.5V and supports access times of 35ns. The device is housed in a 52-lead Plastic Leaded Chip Carrier (PLCC) package, measuring 19.13mm x 19.13mm. It is designed for commercial temperature ranges from 0°C to 70°C.
