70261L20PF8

Memory IC Overview

The Renesas Electronics Corporation 70261L20PF8 is a high-speed 16K x 16 dual-port static random-access memory (SRAM) with a total storage capacity of 256 kbit. It features a parallel asynchronous interface and operates within a supply voltage range of 4.5 V to 5.5 V. The component provides a maximum access time of 20 ns and supports an industrial operating temperature range from -40°C to +85°C. It is housed in a 100-pin TQFP surface-mount package.

Memory IC Feature Summary

• True dual-ported memory cells enabling simultaneous independent access to the same memory location by both ports.
• On-chip hardware support for semaphore signaling and port arbitration logic to manage data conflicts between processors.
• Separate upper-byte and lower-byte control lines designed for compatibility with multiplexed bus architectures.

Memory IC Applications

• Stand-alone dual-port RAM configurations in embedded systems.
• Master/Slave dual-port RAM combinations for 32-bit or wider word systems.
• High-performance data buffering in telecommunications equipment.

Memory IC Procurement Notes

Verify the exact suffix configuration, as the requested model may be listed under similar identifiers such as 70261L20PFGI or 70261L20PFI8 depending on packaging type. Confirm RoHS compliance status and moisture sensitivity level requirements against current datasheet specifications before finalizing procurement orders.

Memory IC Selection Notes

Select this component when simultaneous read/write access from two distinct masters is required without external arbitration circuitry. Ensure the design accommodates the 100-pin TQFP footprint and meets the 4.5V to 5.5V power supply constraints. Verify that the 20 ns access speed aligns with the system clock requirements.
