Infineon Technologies CY7C1370KV33-200AXI

Overview

CY7C1370KV33-200AXI from Cypress Semiconductor is a 18-Mbit (512K × 36) pipelined synchronous SRAM with NoBL™ architecture, ECC support, 3.3 V core supply, 200 MHz max clock frequency, and 100-pin TQFP package. It enables zero-wait-state back-to-back read/write operations in high-throughput memory subsystems for network packet buffering and baseband processing.

For engineers reviewing the CY7C1370KV33-200AXI datasheet, CY7C1370KV33-200AXI pinout, CY7C1370KV33-200AXI application, or CY7C1370KV33-200AXI equivalent, key selection criteria include burst order configuration (linear/interleaved), byte-write select timing, synchronous self-timed write latency, and ECC correction capability for soft error mitigation in telecom infrastructure.

Technical Context

This SRAM implements fully registered inputs and outputs synchronized to the rising edge of CLK, with internal self-timed output buffer control eliminating asynchronous OE dependency. The device supports linear or interleaved burst addressing via MODE strap and uses four byte-write selects (BWa–BWd) to enable granular 9-bit data writes per DQ group.

It integrates on-chip ECC encoding/decoding for single-bit error correction and double-bit error detection, and includes IEEE 1149.1 JTAG boundary scan with TCK/TMS/TDI/TDO pins. Sleep mode is activated by the asynchronous ZZ input, reducing power during idle cycles without clock stop requirement.

FAQ

What is the function of the MODE pin on CY7C1370KV33-200AXI?

The MODE pin is a hardware strap that selects burst address order: pulled HIGH for interleaved burst (default when floating), LOW for linear burst. It must remain static during operation and is sampled at power-up/reset. This setting directly affects how the internal address counter increments during burst accesses, aligning with ASIC or FPGA memory controller expectations.

Does CY7C1370KV33-200AXI require an external clock buffer for 200 MHz operation?

No external clock buffer is required. The device accepts a clean, single-ended CMOS clock directly on the CLK pin with specified AC timing (tSKO skew, tCH/tCL pulse widths). Its internal clock distribution network and CEN qualification ensure robust 200 MHz operation when layout guidelines for clock routing and decoupling are followed per the datasheet.

How does the ZZ sleep mode interact with ongoing memory transactions?

Asserting ZZ HIGH immediately halts new access initiation but allows in-progress read/write cycles to complete normally. Outputs enter high-impedance state after the current cycle, and core logic enters low-power state. No data loss occurs, and the device resumes full operation within one clock cycle after ZZ is deasserted - preserving address and burst state.

Can CY7C1370KV33-200AXI operate with 2.5 V VDDQ while maintaining 3.3 V VDD?

Yes. VDDQ is independently supplied and supports 2.5 V ± 0.2 V for I/O interfacing, while VDD remains at 3.3 V ± 0.3 V for core logic. This dual-supply configuration enables direct connection to 2.5 V FPGA I/O banks without level shifters, provided VDDQ ramp time meets tVDDQ specification and noise coupling between supplies is minimized per layout recommendations.
