Infineon Technologies CY7C09369V-6AXC

Overview

CY7C09369V-6AXC from Cypress Semiconductor is a 3.3V, 16K × 18-bit synchronous dual-port static RAM with true dual-port architecture enabling simultaneous independent read/write access to any memory location. It supports pipelined (100 MHz) and flow-through modes, features 6.5 ns pipelined clock-to-data access, 10 μA typical CMOS standby current, and operates across commercial temperature range (0°C to +70°C). Used in high-speed inter-processor communication and FPGA co-processor buffering.

For engineers reviewing the CY7C09369V-6AXC datasheet, CY7C09369V-6AXC pinout, CY7C09369V-6AXC application, or CY7C09369V-6AXC equivalent, this page delivers verified timing parameters, validated TQFP-100 pin mapping, byte-select control logic, burst counter behavior, and real-world dual-port memory integration guidance - all confirmed against Cypress Document #38-06056 Rev. *C.

Technical Context

This device implements two fully synchronous, independent ports with dedicated address, data, and control registers per port - including separate CLK, ADS, CNTEN, CNTRST, CE0/CE1, R/W, OE, LB/UB, and FT/PIPE inputs. Each port supports internal burst addressing triggered by ADS assertion and incremented on rising CLK edges when CNTEN is active.

Pipelined mode registers output data for minimal cycle time (tCYC2 = 10 ns), while flow-through mode bypasses the output register for zero-latency access (tCD1 = 15 ns). The 0.35 µm CMOS process enables 115 mA typical active current at 100 MHz operation and automatic power-down via CE0/CE1 control.

FAQ

What is the maximum guaranteed clock frequency for CY7C09369V-6AXC in pipelined mode?

The CY7C09369V-6AXC is rated for 100 MHz maximum clock frequency in pipelined mode, corresponding to a 10 ns minimum clock cycle time (tCYC2). This is validated across the commercial temperature range (0°C to +70°C) and 3.3 V ± 300 mV supply, per Cypress Document #38-06056 Rev. *C, page 7.

Does CY7C09369V-6AXC support simultaneous read and write to the same memory address?

Yes - the device uses true dual-ported memory cells that permit simultaneous access to the same location. However, Cypress explicitly states in Note 11 that "when writing simultaneously to the same location, the final value cannot be guaranteed," meaning coherency must be managed externally via software or hardware arbitration.

How does the burst counter operate, and what triggers its reset?

The burst counter loads the current address on ADS assertion and increments on each rising CLK edge when CNTEN is LOW. CNTRST is asynchronous: asserting it LOW resets the counter to zero regardless of ADS or CNTEN state. This enables precise control over burst start points in streaming applications like video line buffers or FIFO emulation.

Can CY7C09369V-6AXC be used in industrial temperature applications?

No - the -6AXC suffix denotes the commercial temperature grade (0°C to +70°C). For industrial operation (–40°C to +85°C), the correct variant is CY7C09369V-6AXI, which shares identical electrical and functional specifications but is qualified across the extended range per the same datasheet's Operating Range table on page 5.
