7035S20PF

Memory IC Overview

The Renesas 7035S20PF is a high-speed, asynchronous dual-port static random-access memory (SRAM) with a total density of 144 kilobits. The internal memory organization is configured as 8K words by 18 bits per word. It operates within a single 5V power supply range and supports parallel interface communication. The device guarantees a maximum access time of 20 nanoseconds. It is housed in a 100-lead Thin Quad Flat Package (TQFP) designed for surface-mount technology applications.

Memory IC Feature Summary

• True dual-port architecture enables simultaneous independent read and write operations from either port without conflict.
• Integrated hardware semaphore signaling logic facilitates automatic data synchronization between the two ports.
• Supports master/slave configuration to expand memory capacity for wider data bus systems without external logic.
• Includes on-chip interrupt flag generation to notify the host processor of specific memory events.

Memory IC Applications

• High-performance digital signal processing systems requiring concurrent data access
• Multiprocessor architectures utilizing shared memory resources
• Industrial automation controllers needing reliable non-volatile-like data buffering
• Telecommunications equipment requiring fast packet switching buffers

Memory IC Procurement Notes

Verify the exact suffix designation against the manufacturer's current datasheet to confirm package dimensions and pinout compatibility. Confirm RoHS compliance status and moisture sensitivity level requirements prior to assembly planning. Ensure the ordering code matches the specific temperature grade and lead finish intended for the production environment.

Memory IC Selection Notes

Select this component when a system requires true simultaneous access to shared data from multiple processors or buses. The integrated arbitration logic simplifies design complexity compared to solutions requiring external control circuits. Verify that the 5V supply voltage aligns with the target system's power distribution network and I/O voltage levels.

Memory IC Part Context

This device belongs to the 7035 series of dual-port SRAMs manufactured by Renesas Electronics. The series provides various speed grades and package options to suit different performance and form factor requirements. These components are widely utilized in embedded systems where deterministic timing and high-speed data sharing are critical operational parameters.

Memory IC Replacement Considerations

Consult official substitution lists for compatible parts such as the IDT7035S20PFG or equivalent Renesas variants. Verify functional equivalence regarding pinouts, access times, and power consumption before implementing any alternative component in the design.
