Infineon Technologies CY7C1360C-200AJXC

Overview

CY7C1360C-200AJXC from Infineon Technologies (formerly Cypress) is a 9-Mbit pipelined synchronous SRAM with 256K × 36 organization, supporting 200 MHz bus operation, 3.3 V core supply (VDD), and 2.5 V/3.3 V I/O (VDDQ). It features registered inputs/outputs, IEEE 1149.1 JTAG boundary scan, and is packaged in Pb-free 100-pin TQFP for high-speed cache and buffer applications in networking switches and telecom line cards.

For engineers reviewing the CY7C1360C-200AJXC datasheet, CY7C1360C-200AJXC pinout, CY7C1360C-200AJXC application, or CY7C1360C-200AJXC equivalent, key selection criteria include burst-mode timing compliance, byte-write control granularity (BWA–BWD), dual chip-enable architecture (CE1/CE2), and ZZ sleep mode current (≤40 mA standby).

Technical Context

This SRAM implements a synchronous, clock-driven pipeline with positive-edge-triggered CLK controlling registration of addresses, data, CE1/CE2/CE3, ADSP/ADSC/ADV, BWE/BWX, and GW. All read/write cycles are self-timed and synchronized to CLK, enabling deterministic 3.0 ns clock-to-output delay at 200 MHz.

Burst addressing is generated internally via a two-bit counter, supporting both Intel Pentium®-compatible interleaved and linear sequences. The device supports asynchronous OE and ZZ (deep power-down), with separate processor (ADSP) and controller (ADSC) address strobes for multi-master system integration.

FAQ

What is the function of the MODE pin on CY7C1360C-200AJXC?

The MODE pin selects burst address sequence behavior: when LOW, it configures the internal two-bit counter for Intel Pentium®-compatible interleaved bursts; when HIGH, it enables linear burst addressing. This setting is sampled at power-up or reset and remains static during operation, directly determining how ADV transitions increment the address counter.

Does CY7C1360C-200AJXC support 2.5 V-only I/O operation?

Yes. VDDQ may be independently supplied at 2.5 V while VDD remains at 3.3 V, enabling direct interface with 2.5 V FPGAs or ASICs. Input thresholds remain compatible with LVTTL levels, and output drive strength is specified for both 2.5 V and 3.3 V VDDQ conditions per datasheet AC characteristics tables.

How does the ZZ (sleep) mode interact with ongoing read/write operations?

ZZ is asynchronous and takes effect immediately upon assertion, halting all internal clocks and disabling outputs. Any active read or write cycle in progress is completed before sleep activation; no data corruption occurs. Exit from ZZ is also asynchronous and requires tZZEX (100 ns max) before first valid access.

Can CE3 be used in the 100-pin TQFP package of CY7C1360C-200AJXC?

Yes. The -AJXC suffix denotes the 3-chip-enable TQFP variant (A version), where CE3 is assigned to pin 71. CE3 functions identically to CE1/CE2 for depth expansion but is omitted in the 2-CE TQFP (-AJ) and 119-ball BGA variants, as confirmed in the pin configuration diagrams (Figures 1 and 3) of datasheet 38-05540 Rev. *U.
