70T3519S133BFI8

Memory IC Overview

The Renesas 70T3519S133BFI8 is a synchronous dual-port static random-access memory (SRAM) device with a total storage capacity of 9 Mbit. The memory organization is structured as 256K words by 36 bits. It supports a maximum clock frequency of 133 MHz and features an access time of 4.2 ns. The component operates within a supply voltage range of 2.4 V to 2.6 V. It utilizes a parallel interface and is housed in a 208-pin CABGA package measuring 15x15 mm. The device is rated for an operating temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access to the same memory array via two distinct port interfaces.
• Synchronous operation synchronized to a single clock signal, supporting high-speed data transfer rates up to 133 MHz.
• Integrated collision detection logic to manage arbitration when both ports attempt simultaneous access to the same address.

Memory IC Applications

• High-performance networking equipment requiring rapid packet buffering and switching.
• Telecommunications infrastructure utilizing digital signal processing for real-time data handling.
• Industrial automation systems demanding deterministic memory access for control logic.

Memory IC Procurement Notes

Verify the specific suffix 'I8' against official Renesas documentation to confirm package type and moisture sensitivity level. Confirm RoHS compliance status as sources indicate non-compliance for this series. Validate lead-free status and check for recent product change notices regarding labeling or material composition updates before finalizing procurement specifications.

Memory IC Selection Notes

Select this component when a system requires independent read/write capabilities on a shared memory space without external arbitration hardware. Ensure the design accommodates the 2.5V core voltage requirement and the 208-pin CABGA footprint. Verify that the 4.2 ns access time meets the timing constraints of the host processor or FPGA interface at the target clock frequency.

Memory IC Part Context

This part belongs to the 70T3519/99/89 family of synchronous dual-port SRAMs manufactured by Renesas Electronics. These devices are designed for applications requiring high bandwidth and low latency. The family shares common architectural features but varies in density and speed grades. The 70T3519 variant specifically provides 9 Mbit capacity in a 36-bit word width configuration.

Memory IC Replacement Considerations

Publicly confirmed substitute part numbers for this specific component were not identified in the provided source material. Consult official Renesas cross-reference guides or datasheets for potential alternatives such as other members of the 70T35xx series or legacy IDT equivalents if pin compatibility is required.
