7008L15J

Memory IC Overview

The Renesas Electronics Corporation 7008L15J is a high-speed, asynchronous dual-port static random-access memory (SRAM) device. It provides a storage capacity of 512 kilobits organized as 64K words by 8 bits. The component features true dual-ported memory cells that allow simultaneous independent reads and writes from either port without conflict. It operates with a TTL-compatible single 5V power supply within the 4.5V to 5.5V range. The device supports an access time of 15 nanoseconds and is housed in an 84-pin Plastic Leadless Chip Carrier (PLCC) package measuring 29.31mm x 29.31mm. It functions within a commercial temperature range of 0°C to 70°C.
