Cypress Semiconductor Corp CY7C1415AV18-200BZC

Overview

CY7C1415AV18 from Cypress Semiconductor is a 1M × 36-bit, 36-Mbit QDR-II SRAM with synchronous pipelined architecture, dual independent read/write ports, 200 MHz clock operation (600 MHz DDR data rate), and 165-ball FBGA package. It delivers full data coherency, HSTL I/O compatibility, and on-chip DLL for precise timing in high-bandwidth networking buffers and packet memory applications.

For engineers reviewing the CY7C1415AV18 datasheet, CY7C1415AV18 pinout, CY7C1415AV18 application, or CY7C1415AV18 equivalent, key selection criteria include burst depth (4-word), port independence, echo clock support (CQ/CQ), VDDQ = 1.4–1.8 V range, and x36 bus width for parallel data throughput in switch fabric controllers.

Technical Context

This device implements QDR-II architecture with physically separate read and write data paths-no bus turnaround required. Address inputs are multiplexed and latched on alternating rising edges of K/K clocks, enabling concurrent read/write operations at full bandwidth.

Read data is output-synchronized to C/C clocks with echo clocks (CQ/CQ) referenced to those outputs, minimizing skew in multi-device systems. Internal self-timed writes and DLL-controlled data placement ensure deterministic timing across temperature and voltage variations.

FAQ

What is the minimum VDDQ voltage supported by CY7C1415AV18?

The device supports VDDQ from 1.4 V to 1.8 V. Operation below 1.4 V is not guaranteed-HSTL-18 output drive strength and timing parameters are specified only within this range. Using 1.4 V minimizes I/O power while maintaining full AC performance at 200 MHz.

Can CY7C1415AV18 operate without the DLL enabled?

Yes-asserting DOFF (low) disables the DLL, placing the device in static timing mode. However, AC characteristics change significantly: tAC increases by up to 1.2 ns, and setup/hold margins shrink. This mode is intended only for functional verification or ultra-low-power standby-not for normal operation at 200 MHz.

How many address bits does CY7C1415AV18 require?

It requires 18 address bits (A[17:0]) to access the full 1M × 36-bit array. The internal organization is four 256K × 36 banks, and address multiplexing allows full addressing with a single 18-bit bus shared between read and write ports.

Is ZQ pin mandatory for operation?

ZQ must be connected-either to a 240 Ω resistor to ground (for calibrated 48 Ω output impedance) or directly to VDDQ (for minimum impedance mode). Leaving ZQ floating or tied to VSS violates Absolute Maximum Ratings and may cause output driver instability or excessive current draw.
