Infineon Technologies CY7C09199V-9AXC

Overview

CY7C09199V-9AXC from Cypress Semiconductor is a 128K × 9-bit synchronous dual-port static RAM with true dual-port architecture, pipelined/flow-through mode selection via FT/PIPE pin, 67 MHz max clock frequency (pipelined), 9 ns max clock-to-data access time, and 3.3 V operation - deployed in high-speed network packet buffering and real-time DSP data exchange systems.

For engineers reviewing the CY7C09199V-9AXC datasheet, CY7C09199V-9AXC pinout, CY7C09199V-9AXC application, or CY7C09199V-9AXC equivalent, key selection criteria include simultaneous left/right port timing independence, burst counter support for interleaved addressing, CMOS-level standby current of 10 μA, and TQFP-100 package compatibility with industrial temperature range (–40°C to +85°C).

Technical Context

This device implements two fully independent synchronous interfaces - each with dedicated clock (CLKL/CLKR), address strobe (ADSL/ADSR), chip enables (CE0L/CE1L and CE0R/CE1R), and read/write control (R/WL/R/WR) - enabling concurrent read/write operations to any memory location without arbitration logic. The internal burst counter increments on rising clock edges when CNTEN is asserted, supporting automatic sequential addressing across the full 128K depth.

Operation supports three modes: pipelined (FT/PIPE = HIGH, tCD2 = 9 ns), flow-through (FT/PIPE = LOW, tCD1 = 20 ns), and burst (enabled via CNTEN + ADS). Power management includes dual-chip-enable auto-power-down and CMOS-level standby (ISB3 = 10 μA), critical for low-power embedded telecom subsystems.

FAQ

What is the maximum operating frequency in pipelined mode for CY7C09199V-9AXC?

The CY7C09199V-9AXC supports up to 67 MHz in pipelined mode, corresponding to a 15 ns clock cycle time (tCYC2). This is confirmed in the "Switching Characteristics" table on page 7 of datasheet 38-06043 Rev. *C, under parameter fMAX2 for the -9 speed grade. Operation above this frequency risks setup/hold violations and data corruption.

Does CY7C09199V-9AXC support burst addressing on both ports simultaneously?

Yes - each port has independent CNTENL/CNTENR and ADSL/ADSR inputs, allowing concurrent burst operations. When CNTEN is asserted and ADS is pulsed LOW, the respective port's internal counter loads the address and increments on subsequent CLK edges. Both counters operate autonomously without cross-port dependency.

Can CY7C09199V-9AXC be used in flow-through mode with zero-cycle latency?

Yes - asserting FT/PIPE = LOW enables flow-through mode, where output data appears 20 ns after clock edge (tCD1), with no pipeline register delay. This mode bypasses the output register entirely, delivering combinatorial read access ideal for applications requiring minimal latency over throughput.

Is the 100-pin TQFP package of CY7C09199V-9AXC RoHS-compliant and lead-free?

Yes - the "-9AXC" suffix denotes a lead-free, RoHS-compliant 100-pin TQFP package, as stated in the "Features" section of the datasheet and confirmed in Cypress's packaging nomenclature guide. The device meets JEDEC J-STD-609 Category 1 marking requirements for Pb-free labeling.
