70261L20PFI8

Memory IC Overview

The Renesas Electronics Corporation 70261L20PFI8 is a static random-access memory component with a storage capacity of 256 kbit, organized as 16 k x 16. It features a parallel interface and an access time of 20 ns. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from -40°C to +85°C. It utilizes SMD/SMT installation in a TQFP-100 package.

Memory IC Feature Summary

• Asynchronous dual-port architecture enabling simultaneous independent access
• Integrated hardware support for semaphore signaling between ports
• Automatic power down feature controlled by chip enable

Memory IC Applications

• Stand-alone dual-port RAM systems
• Master/Slave dual-port configurations for 32-bit or wider word systems
• Multiplexed bus compatibility applications requiring separate byte control

Memory IC Procurement Notes

Verify RoHS compliance status as the source indicates non-compliance. Confirm end-of-life status and limited availability through authorized channels. Validate moisture sensitivity level requirements during handling. Ensure pinout and package dimensions match the TQFP-100 specification before integration into existing designs.

Memory IC Selection Notes

Select this component for applications requiring high-speed asynchronous data exchange between two independent processors. Consider the industrial temperature range for harsh environments. Evaluate power consumption needs against the automatic power-down capabilities. Verify that the 5V TTL-compatible supply matches system voltage levels.

Memory IC Part Context

This part belongs to the 70261 series of high-speed dual-port SRAMs. It shares architectural similarities with other variants like the 70261L15 and 70261S35, differing primarily in access speed and specific suffix designations. The series is designed for robust data buffering and protocol conversion tasks.
