70T3599S133BFGI

Memory IC Overview

The Renesas 70T3599S133BFGI is a synchronous dual-port static random-access memory (SRAM) device. It features a storage capacity of 4.5 Mbit, organized as 128K words by 36 bits. The component operates with a maximum clock frequency of 133 MHz and supports a minimum access time of 4.2 ns. It requires a supply voltage range of 2.4 V to 2.6 V. The device utilizes a parallel interface and is housed in a CABGA-256 package.

Memory IC Feature Summary

• Provides independent read/write access for two masters via dual-port architecture
• Supports high-speed data transfer through synchronous operation at up to 133 MHz
• Integrates parity checking capabilities within the 36-bit word structure

Memory IC Applications
