Infineon Technologies CY7C1360C-166AJXCT

Overview

CY7C1360C-166AJXCT from Cypress Semiconductor is a 9-Mbit pipelined synchronous SRAM configured as 256K × 36, operating at 166 MHz with 3.3 V core and 2.5/3.3 V I/O supplies, registered inputs/outputs for burst timing control, and IEEE 1149.1 JTAG boundary scan - used in high-speed network packet buffers and CPU cache coherency interfaces.

For engineers reviewing the CY7C1360C-166AJXCT datasheet, CY7C1360C-166AJXCT pinout, CY7C1360C-166AJXCT application, or CY7C1360C-166AJXCT equivalent, key selection criteria include burst sequence mode (Intel Pentium® interleaved/linear), byte-write granularity (BWA–BWD + BWE), clock-to-output timing (3.5 ns), and TQFP-100 Pb-free package compatibility with CE1/CE2/CE3 address-pipelining enable logic.

Technical Context

This SRAM implements a two-bit internal burst counter synchronized to CLK, with ADSP/ADSC dual address strobes enabling processor- and controller-initiated access. All synchronous inputs-including addresses, BWx, GW, CE1–CE3, and ADV-are registered on the rising edge of CLK.

It supports synchronous self-timed writes with byte-selectable width (1–4 bytes via BWA–BWD and BWE), asynchronous OE and ZZ controls, and JEDEC JESD8-5-compliant I/Os. The device delivers a 3-1-1-1 access rate and supports both interleaved and linear burst sequences under MODE pin configuration.

Key Specifications

Pinout & Package

FAQ

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

The MODE pin selects between Intel Pentium®-compatible interleaved and linear burst address sequences. When MODE = LOW, the device uses interleaved addressing (e.g., 0, 2, 4, 6); when MODE = HIGH, it uses linear addressing (e.g., 0, 1, 2, 3). This setting must be stable before initialization and remains latched during operation.

Can CY7C1360C-166AJXCT operate with VDDQ = 2.5 V while VDD = 3.3 V?

Yes. The device supports independent 3.3 V core (VDD) and 2.5 V or 3.3 V I/O (VDDQ) supplies. This allows direct interfacing with 2.5 V FPGAs or ASICs while maintaining full 3.3 V internal performance. VSSQ must be tied to the same ground as VSS, and VDDQ decoupling is required per datasheet layout guidelines.

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

When ZZ is driven HIGH, the device enters a non-time-critical sleep mode with typical standby current ≤ 40 mA - reducing dynamic power by >90%. Data integrity is fully maintained during sleep, and the device resumes normal operation within one CLK cycle after ZZ returns LOW, with no initialization delay or data loss.

Is the CY7C1360C-166AJXCT pin-compatible with the CY7C1362C-166AXC?

No. Although both share the same 100-pin TQFP footprint, CY7C1360C (256K × 36) and CY7C1362C (512K × 18) differ in data bus width, parity pin assignment (DQPA–DQPD vs. no parity), and internal address mapping. Their pinouts are electrically incompatible - direct replacement requires PCB redesign and firmware adaptation.
