Infineon Technologies CY7C1360C-166AXCT

Overview

CY7C1360C-166AXCT from Infineon Technologies (formerly Cypress) is a 9-Mbit pipelined synchronous SRAM with 256K × 36 organization, supporting 166 MHz bus operation, 3.3 V core supply (VDD), and 2.5 V/3.3 V I/O (VDDQ). It features registered inputs/outputs, synchronous self-timed writes, and IEEE 1149.1 JTAG boundary scan - deployed in high-speed network packet buffers and telecom line-card control planes.

For engineers reviewing the CY7C1360C-166AXCT datasheet, CY7C1360C-166AXCT pinout, CY7C1360C-166AXCT application, or CY7C1360C-166AXCT equivalent, key selection criteria include burst mode compatibility (Intel Pentium® interleaved/linear), 3-chip-enable TQFP package support, clock-to-output timing (3.5 ns), and byte-write granularity (1–4 byte width via BWx pins).

Technical Context

The device implements a two-bit internal burst counter synchronized to CLK's rising edge, enabling automatic address generation upon ADV assertion. All address, data, and control inputs (CE1/CE2/CE3, ADSP/ADSC, BWE/BWX, GW) are registered, while OE and ZZ remain asynchronous for fast output enable and low-power sleep control.

It supports dual-voltage I/O operation (2.5 V or 3.3 V on VDDQ), JEDEC JESD8-5-compliant signaling, and configurable depth expansion via CE2/CE3. The 100-pin TQFP package (A version) includes dedicated pins for MODE, ADV, ADSP, ADSC, and three independent chip enables - essential for multi-bank memory subsystems requiring deterministic latency.

Manufacturer

Infineon Technologies acquired Cypress Semiconductor in 2020 and maintains the former Cypress SRAM portfolio, including high-performance pipelined memories, with full technical and supply chain continuity.

This device belongs to the CY7C136x pipelined SRAM product line, engineered specifically for deterministic-latency, high-bandwidth buffering in telecom, defense, and industrial real-time systems where synchronous burst performance outweighs cost-per-bit optimization.

FAQ

What is the function of the MODE pin on CY7C1360C-166AXCT?

The MODE pin selects burst address sequence behavior: logic HIGH configures Intel Pentium®-compatible interleaved addressing (e.g., 0, 2, 4, 6), while logic LOW enables linear addressing (e.g., 0, 1, 2, 3). This setting is sampled at power-up and remains static during operation - no runtime reconfiguration is supported.

Can CY7C1360C-166AXCT operate with only 2.5 V on both VDD and VDDQ?

No. VDD must be 3.3 V ±0.3 V for core logic operation; only VDDQ may be 2.5 V or 3.3 V. Applying 2.5 V to VDD violates absolute maximum ratings and will prevent internal registers and sense amplifiers from functioning correctly, resulting in data corruption or functional failure.

Is CE3 functional in the 100-pin TQFP package of CY7C1360C-166AXCT?

Yes - CE3 is present and fully functional in the "A version" of the 100-pin TQFP package (as indicated by suffix 'XCT' and confirmed in Figure 1 of datasheet 38-05540 Rev. *U). It is absent in the "AJ version" (2-CE variant) and 119-ball BGA packages, which support only CE1 and CE2.

Does CY7C1360C-166AXCT support concurrent read and write operations on the same memory array?

No. The device implements a single-port synchronous SRAM architecture: read and write operations are mutually exclusive per cycle. While pipelining allows overlapping address setup and data transfer, true simultaneous R/W (like dual-port RAM) is not supported - attempting concurrent access results in bus contention or undefined data output.
