Infineon Technologies CY7C1360C-166AXIT

Overview

CY7C1360C-166AXIT from Cypress Semiconductor is a 9-Mbit pipelined synchronous SRAM configured as 256K × 36, operating at 166 MHz with 3.3 V core supply (VDD) and 2.5 V/3.3 V I/O (VDDQ), supporting Intel Pentium®-compatible interleaved or linear burst sequences in high-speed bus interfaces for network packet buffering and real-time DSP memory subsystems.

For engineers reviewing the CY7C1360C-166AXIT datasheet, CY7C1360C-166AXIT pinout, CY7C1360C-166AXIT application, or CY7C1360C-166AXIT equivalent, key selection criteria include registered input/output timing, 3.0 ns clock-to-output (at 200 MHz grade), synchronous self-timed write capability, byte-selectable write width (1–4 bytes), and TQFP-100 Pb-free packaging with JTAG boundary scan compliance.

Technical Context

The device implements a two-bit internal burst counter synchronized to CLK, with address registration triggered by either ADSP (processor strobe) or ADSC (controller strobe), enabling deterministic pipeline depth control. All synchronous inputs-including CE1/CE2/CE3, BWx, GW, BWE, ADV, and MODE-are edge-triggered on CLK's rising edge.

Asynchronous controls OE and ZZ operate independently of CLK: OE enables tristate output control during read cycles, while ZZ asserts sleep mode with data retention and reduced standby current (40 mA max). The memory array supports synchronous self-timed writes and single-cycle chip deselect, with JEDEC JESD8-5-compatible I/O voltage tolerance.

FAQ

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

The MODE pin selects burst address sequencing: logic HIGH configures Intel Pentium®-compatible interleaved addressing, while logic LOW enables linear burst mode. This hardware-selectable feature ensures direct compatibility with different host controller architectures without firmware changes or external logic.

Does CY7C1360C-166AXIT support 2.5 V-only I/O operation?

Yes - VDDQ accepts 2.5 V ±0.2 V, and all I/O pins (DQx, DQPx, BWx, etc.) are JESD8-5 compliant, allowing full 2.5 V signaling when VDDQ = 2.5 V and VDD = 3.3 V. No level-shifting circuitry is required for interfacing with 2.5 V logic families.

How does the ZZ pin affect power consumption and data retention?

When ZZ is driven HIGH, the device enters non-time-critical sleep mode with core clocks gated but memory array powered - retaining all stored data while reducing typical standby current to ≤40 mA. Data remains valid indefinitely as long as VDD and VDDQ remain within specification.

Can CY7C1360C-166AXIT be used in place of CY7C1362C-166AXIT?

No - CY7C1360C is 256K × 36 (9 Mbit), while CY7C1362C is 512K × 18 (9 Mbit), differing in data bus width and address mapping. They share pinout and timing but require PCB layout and firmware changes due to distinct memory organization and burst counter behavior.
