Infineon Technologies CY7C1413JV18-300BZC

Overview

CY7C1413JV18 from Cypress Semiconductor is a 36-Mbit QDR-II SRAM with 2M × 18 organization, operating at 300 MHz with DDR interfaces on independent read/write ports, 1.8 V core supply, and 1.4–1.8 V I/O supply. It delivers 600 MHz effective data rate, 1.5-cycle read latency (DLL enabled), and supports burst-4 sequential transfers for high-bandwidth networking buffer applications.

For engineers reviewing the CY7C1413JV18 datasheet, CY7C1413JV18 pinout, CY7C1413JV18 application, or CY7C1413JV18 equivalent, key selection criteria include its dual-clock DDR timing architecture, echo clock (CQ/CQ) support for skew compensation, HSTL-compatible 165-ball FBGA package, and synchronous self-timed write capability in high-speed packet buffering systems.

Technical Context

The CY7C1413JV18 implements QDR-II architecture with physically separate read and write data paths, eliminating bus turnaround overhead. Its 18-bit bidirectional data width (D[17:0]/Q[17:0]) operates with 19 address lines (A[18:0]), supporting 512K × 18 internal array segmentation across four banks.

It uses two independent clock domains: K/K for address/data capture and C/C for output timing, with CQ/CQ echo clocks synchronized to C/C for precise source-synchronous data capture. The integrated DLL enables 1.5-cycle read latency at 300 MHz; disabling DOFF reverts operation to QDR-I mode (1-cycle latency, ≤167 MHz).

CY7C1413JV18 belongs to the QDR-II SRAM product line, engineered specifically for deterministic-latency, high-throughput data buffering in packet-switched infrastructure where concurrent read/write bandwidth and source-synchronous timing are mandatory.

FAQ

What is the minimum supported clock frequency for CY7C1413JV18?

The device has no specified minimum clock frequency; it operates down to DC. All timing parameters scale linearly with clock period, and the DLL remains functional across the full 300 MHz to static operation range. System-level hold time requirements must be verified at low frequencies using the AC timing table's tH and tSU specifications.

Can CY7C1413JV18 be used with only a single clock (K) instead of differential K/K?

Yes - the device supports single-ended clocking on K only. In this mode, K is ignored, and all inputs (address, data, controls) are sampled on K's rising edge. Output timing defaults to K for Q[17:0], and C/C must still be provided for read data strobing; CQ/CQ remain active and referenced to C.

How does ZQ calibration affect signal integrity in high-speed layouts?

ZQ calibration adjusts output driver impedance to match the PCB trace impedance (typically 50 Ω). With ZQ tied to a 50 Ω resistor to ground, Q[17:0] and CQ/CQ outputs achieve 0.2 × 50 Ω = 10 Ω driver impedance, enabling proper series termination and reducing reflections on point-to-point HSTL buses up to 600 MT/s.

Is JTAG accessible during normal memory operation?

Yes - the TAP controller operates independently of memory access. JTAG signals (TCK/TMS/TDI/TDO) are sampled asynchronously and do not interfere with K/K or C/C timing domains. Boundary scan testing can be performed without halting data traffic, supporting in-system diagnostics in live network equipment.
