70T3339S133BCI

Memory IC Overview

The 70T3339S133BCI is a high-speed synchronous dual-port SRAM with a 9Mbit capacity organized as 512K x 18 bits. It operates at clock frequencies up to 133 MHz with a 4.2 ns access time. The device supports a 2.4V to 2.6V core supply voltage and features a 208-CABGA (15x15) package. It includes JTAG functionality, collision detection, and sleep mode capabilities for power management.

Memory IC Feature Summary

• Simultaneous independent access to memory locations via dual ports
• Integrated JTAG interface for boundary scan testing
• Configurable sleep mode for reduced standby power consumption
• Hardware support for collision detection and interrupt signaling

Memory IC Applications

• High-performance networking equipment requiring low-latency data buffering
• Industrial automation systems needing reliable bidirectional data flow
• Telecommunications infrastructure utilizing synchronous parallel interfaces
• Embedded control systems requiring hardware semaphore support

Memory IC Procurement Notes

Verify component authenticity through authorized Renesas distributors or direct manufacturer channels. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Check for recent product change notifications regarding packaging or labeling updates. Ensure ESD protection measures are followed during handling due to the CABGA package type.

Memory IC Selection Notes

Select this component when simultaneous read/write operations on shared memory are required without external arbitration logic. Consider the 208-pin CABGA package for space-constrained PCB layouts. Verify that the 2.4V to 2.6V core voltage range aligns with the system power design. Evaluate the 133 MHz maximum frequency against system timing requirements.

Memory IC Part Context

This part belongs to the 70T3339 family of synchronous dual-port SRAMs from Renesas. It shares architectural similarities with other members like the 70T3319 and 70T3399 but differs in density and organization. The family is designed for applications demanding high throughput and deterministic access times in parallel bus environments.
