Infineon Technologies CY7C1460AV33-167BZC

Overview

CY7C1460AV33-167BZC from Cypress Semiconductor is a 3.3V, 1M × 36 synchronous pipelined SRAM with NoBL™ architecture, supporting true back-to-back read/write operations at 167 MHz with zero wait states. It features fully registered I/O, byte write capability (BWa–BWd), synchronous self-timed writes, and 3.3V/2.5V I/O compatibility. Used in high-throughput packet buffering and network switch fabric control planes.

For engineers reviewing the CY7C1460AV33-167BZC datasheet, CY7C1460AV33-167BZC pinout, CY7C1460AV33-167BZC application, or CY7C1460AV33-167BZC equivalent, key selection criteria include clock-to-output timing (3.4 ns), burst mode support (linear/interleaved), JTAG boundary scan compliance, and 100-pin TQFP or 165-ball FBGA package options.

Technical Context

The device implements a fully synchronous interface with all inputs and outputs registered on the rising edge of CLK, qualified by CEN. Its NoBL™ logic eliminates bus latency by enabling consecutive read/write transfers on every clock cycle without pipeline stalls.

Three chip enables (CE1 active-low, CE2 active-high, CE3 active-low) provide flexible bank selection, while asynchronous OE controls output tristate independently of clock domain. Write operations use synchronous byte write selects (BWa–BWd) and WE, with on-chip self-timed write circuitry ensuring deterministic timing.

Key Specifications

Pinout & Package

Available in JEDEC-standard Pb-Free 100-pin TQFP (14 mm × 14 mm) and Pb-Free 165-ball FBGA (15 mm × 17 mm × 1.4 mm). The 100-pin TQFP variant is used for cost-sensitive, medium-density applications requiring standard surface-mount assembly.

FAQ

What is the function of the MODE pin on CY7C1460AV33-167BZC?

The MODE pin selects burst addressing order: tied to GND enables linear burst, while floating or connected to VDD enables interleaved burst. This setting determines how the internal address counter increments during burst reads/writes and must be configured at power-up before first access.

Does CY7C1460AV33-167BZC support 2.5V-only I/O operation?

Yes - VDDQ accepts 2.5V ±0.2V while VDD remains at 3.3V ±0.3V, allowing direct interfacing with 2.5V logic families without level shifters. DC characteristics including setup/hold times and output drive strength are guaranteed across this I/O voltage range per datasheet Table "DC Electrical Characteristics".

How does the ZZ (Sleep) mode reduce power consumption?

Asserting ZZ LOW places the device in ultra-low-power sleep mode, reducing CMOS standby current to ≤120 µA. During ZZ mode, all internal clocks and output drivers are disabled, but data retention is maintained as long as VDD and VDDQ remain within specification. Exit time is one clock cycle after ZZ deassertion.

Can CE2 be used as an active-low signal instead of active-high?

No - CE2 is strictly defined as active-high per datasheet Pin Definitions and Truth Table. Using it as active-low violates timing and functional specifications, potentially causing undefined chip select behavior. CE1 and CE3 are active-low; CE2 must remain high to enable the device when CE1 and CE3 are asserted.
