Infineon Technologies CY7C1360C-166AXC

Overview

CY7C1360C-166AXC 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 CPU cache coherency subsystems.

For engineers reviewing the CY7C1360C-166AXC datasheet, CY7C1360C-166AXC pinout, CY7C1360C-166AXC application, or CY7C1360C-166AXC equivalent, key selection criteria include burst mode compatibility (Intel Pentium® interleaved/linear), byte-write granularity (1–4 byte width), clock-to-output timing (3.5 ns), and TQFP-100 Pb-free package compliance with JEDEC JESD8-5 I/O standards.

Technical Context

The device implements a two-bit internal burst counter synchronized to CLK's rising edge, enabling automatic generation of sequential addresses upon ADV assertion. All address, data, and control inputs (CE1/CE2/CE3, ADSP/ADSC, BWx, GW) are registered, ensuring deterministic setup/hold timing across 166 MHz operation.

Synchronous write cycles are self-timed and support per-byte write enable via BWA–BWD; asynchronous OE and ZZ (sleep) pins allow output disable and low-power standby independent of clock. The logic block integrates pipelined input registers, output registers, sense amps, and byte-write drivers for concurrent read/write arbitration.

FAQ

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

The MODE pin selects burst address sequence: logic HIGH configures Intel Pentium® interleaved mode (0, 2, 4, 6, 1, 3, 5, 7); logic LOW selects linear mode (0, 1, 2, 3, 4, 5, 6, 7). This setting is sampled at power-up or reset and remains static during operation - no dynamic reconfiguration is supported.

Does CY7C1360C-166AXC support true dual-port operation?

No. The CY7C1360C-166AXC is a synchronous single-port SRAM with pipelined interface. While it supports concurrent read and write within a burst cycle via internal register staging, it lacks independent read/write ports or simultaneous access arbitration logic required for true dual-port functionality.

Can CE3 be used in all package variants of CY7C1360C-166AXC?

No. CE3 is only available on the 100-pin TQFP (A version) and 165-ball FBGA packages. The 119-ball BGA variant supports only CE1 and CE2, as confirmed in the ordering information table and pin diagrams on pages 6 and 7 of the datasheet.

Is the ZZ (sleep) pin compatible with automatic power-gating schemes?

Yes. ZZ is asynchronous and active-low; asserting ZZ places the device in deep power-down mode with typical standby current < 40 µA. It releases automatically on deassertion, with no clock or initialization sequence required - making it suitable for firmware-controlled power gating in energy-aware systems.
