Infineon Technologies CY7C1612KV18-360BZXC

Overview

CY7C1612KV18-360BZXC from Infineon Technologies (formerly Cypress) is a 144-Mbit QDR® II SRAM with 8M × 18 organization, 360 MHz clock frequency, 1.8 V core supply, 1.4–1.8 V I/O supply, and 165-ball FBGA (15 × 17 × 1.4 mm) package. It delivers 720 MT/s DDR throughput on independent read/write ports for high-speed packet buffering in network switches and routers.

For engineers reviewing the CY7C1612KV18-360BZXC datasheet, CY7C1612KV18-360BZXC pinout, CY7C1612KV18-360BZXC application, or CY7C1612KV18-360BZXC equivalent, key selection criteria include QDR II two-word burst timing, DOFF-configurable 1.5-cycle vs. 1-cycle read latency, echo clock (CQ/CQ) support for source-synchronous capture, and HSTL-18-compatible output drive strength.

Technical Context

This QDR II SRAM implements fully independent synchronous read and write ports sharing a multiplexed address bus, with separate K/K clocks for write address/data latching and C/C clocks for read data output timing. Its PLL ensures precise data placement relative to echo clocks, enabling reliable 720 MHz data transfer at 360 MHz clock frequency.

The device supports depth expansion via RPS/WPS and byte-write control through BWS[1:0], maintains full data coherency across concurrent transactions, and operates with 1.5-cycle read latency when DOFF = HIGH or 1-cycle latency when DOFF = LOW-matching legacy QDR I timing when required.

FAQ

What is the function of the DOFF pin on CY7C1612KV18-360BZXC?

The DOFF (Data Output OFFset) pin configures read latency mode: when asserted HIGH, it enables 1.5-cycle read latency (standard QDR II operation); when LOW, it reduces latency to 1 cycle for backward compatibility with QDR I timing. This setting is sampled synchronously on the K clock and affects all subsequent read accesses until changed.

Can CY7C1612KV18-360BZXC operate with 1.5 V VDDQ?

Yes - the device supports VDDQ from 1.4 V to 1.8 V, including 1.5 V. At 1.5 V, it meets HSTL Class I specifications with appropriate termination, enabling interoperability with 1.5 V logic families while maintaining full 360 MHz operation and signal integrity.

How does the echo clock (CQ/CQ) improve system timing margin?

CQ and CQ are output-referenced clocks driven synchronously with Q[17:0] data edges. They provide a local timing reference at the receiver, eliminating flight-time mismatch between clock and data paths - critical for reliable capture at 720 MT/s in multi-drop or long-trace PCB layouts.

Is JTAG boundary scan supported on CY7C1612KV18-360BZXC?

Yes - the device implements IEEE 1149.1 (JTAG) compliant test access port with TDI, TDO, TCK, and TMS pins. Boundary scan supports interconnect testing and allows in-system programming of configuration registers, though no user-programmable nonvolatile storage is present.
