7027L12PFI8

Memory IC Overview

The 7027L12PFI8 is a dual-port asynchronous static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics. It provides a total storage capacity of 512Kbits, organized as 32K words by 16 bits. The device features a parallel interface with a maximum access time of 12 nanoseconds and a write cycle time of 12 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports an ambient operating temperature range from -40°C to +85°C. The component is housed in a 100-pin Thin Quad Flat Package (TQFP) with a 14x14mm footprint.

Memory IC Feature Summary

• Supports simultaneous independent access to data via two distinct port interfaces for concurrent read/write operations.
• Utilizes asynchronous logic control without requiring a system clock signal for data transfer synchronization.
• Maintains stored data content indefinitely while power is supplied, ensuring non-volatile retention during active operation.

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in industrial control systems
• Data storage in network switching hardware

Memory IC Procurement Notes

Verify the specific suffix PFI8 to confirm the tape-and-reel packaging configuration and moisture sensitivity level. Ensure the procurement channel sources genuine Renesas Electronics components to avoid counterfeit devices. Confirm that the supply voltage requirements align with the target system's 5V logic levels before integration.

Memory IC Selection Notes

Select this component when dual-port concurrency is required for 16-bit wide data paths. Compare against single-port alternatives if only one master accesses the memory. Verify that the 12ns speed meets the system timing constraints and that the 5V voltage tolerance matches the host processor I/O standards.

Memory IC Part Context

This part belongs to the 7027 series of dual-port SRAMs, designed for applications needing high-bandwidth data sharing between two processors or controllers. The series offers various speed grades and package options to suit different performance and space requirements in embedded systems.

Memory IC Replacement Considerations

Check for IDT7027L12PFI8 as a potential equivalent from Integrated Device Technology, which shares similar specifications. Verify pin compatibility and electrical characteristics before substituting any alternative dual-port SRAM models.
