Infineon Technologies CY7C0430BV-100BGC

Overview

CY7C0430BV-100BGC from Infineon is a 32K × 16-bit synchronous dual-port static RAM (SRAM) with 3.3 V core voltage, 100 MHz maximum clock frequency, and 10 ns access time, used in high-speed bidirectional data buffering between independent bus systems in networking and industrial controllers.

For engineers reviewing the CY7C0430BV-100BGC datasheet, CY7C0430BV-100BGC pinout, CY7C0430BV-100BGC application, or CY7C0430BV-100BGC equivalent, key selection criteria include dual-port arbitration timing, on-chip busy logic, 3.3 V I/O compatibility, and BGA-119 package thermal performance for real-time inter-processor communication.

Technical Context

This SRAM implements true dual-port architecture with independent address/data buses and control signals per port, supporting simultaneous read/write operations without external arbitration logic. It integrates BUSY logic to prevent collisions during concurrent access and supports BYTE WRITE enable for selective 8-bit updates within 16-bit words.

The device uses a synchronous interface with rising-edge-triggered clocks (CLKA/CLKB), registered control inputs, and programmable output enable (OE) per port. It operates over industrial temperature range (–40°C to +85°C) and meets JEDEC JESD8-15A I/O voltage standards.

FAQ

What is the minimum supported clock frequency for CY7C0430BV-100BGC?

The device has no minimum clock frequency requirement due to its fully synchronous design with registered controls. It supports DC to 100 MHz operation, enabling flexible clock gating and power-saving modes without timing violations or metastability risks during stop/start transitions.

Does CY7C0430BV-100BGC support independent power-down modes per port?

No. The device features a single V_DD supply and global power-down mode activated via PWDN pin. Both ports enter standby simultaneously with reduced current draw (≤50 µA), and full functionality resumes within 100 ns after exit.

Can CY7C0430BV-100BGC be used in asynchronous systems?

No. It requires synchronous clock edges on CLKA and CLKB for all address, control, and data registration. Asynchronous access attempts will result in undefined data output and potential bus contention; external clock generation is mandatory.

Is the BUSY signal asserted during internal self-timed operations like write recovery?

Yes. BUSYA/BUSYB assert during any internal operation that blocks port access-including write recovery, auto-precharge, and arbitration resolution-ensuring masters wait until the memory is ready for next valid command.
