Cypress Semiconductor Corp CY7C1470V33-200AXC

Overview

CY7C1470V33 from Infineon Technologies (formerly Cypress) is a 72-Mbit pipelined synchronous SRAM with NoBL™ architecture, configured as 2M × 36, supporting 200 MHz zero-wait-state bus operation, 3.3 V core supply, and 3.3 V/2.5 V I/O supply. It delivers 3.0 ns clock-to-output time and enables true back-to-back read/write transitions in high-throughput networking and packet buffering systems.

For engineers reviewing the CY7C1470V33 datasheet, CY7C1470V33 pinout, CY7C1470V33 application, or CY7C1470V33 equivalent, key selection criteria include burst mode support (linear/interleaved), synchronous self-timed writes, byte write capability (BWa–BWd), JTAG boundary scan compliance, and TQFP/FBGA package compatibility for memory subsystems requiring deterministic latency.

Technical Context

This SRAM implements fully registered synchronous interfaces: all address, control, and data signals pass through input registers on the rising clock edge, while outputs are driven via output registers synchronized to the same edge. The NoBL™ logic eliminates bus latency by enabling consecutive read/write operations without wait states.

It supports three chip enables (CE1/CE2/CE3) for bank selection, asynchronous OE for output tristate control, and clock enable (CEN) to suspend operation. Write cycles use synchronous self-timed circuitry with byte-write select inputs (BWa–BWd), and includes ZZ sleep mode with external grounding requirement per errata.

FAQ

What is the required connection for the ZZ pin on CY7C1470V33?

The ZZ pin (Pin 64 in TQFP, Ball H11 in FBGA) must be externally connected to ground to enable proper sleep mode operation, as documented in Errata on page 35 of datasheet 38-05289 Rev. *Y. Leaving ZZ floating or pulling high disables sleep functionality and may cause undefined behavior during low-power states.

Does CY7C1470V33 support 2.5 V I/O voltage while operating at 3.3 V core?

Yes - the device features separate VDDQ pins for I/O supply, allowing operation at either 3.3 V or 2.5 V independent of the 3.3 V VDD core supply. This dual-voltage I/O capability enables seamless interfacing with both 3.3 V and 2.5 V logic families without level shifters.

How many byte write enable signals does CY7C1470V33 provide?

CY7C1470V33 provides four byte write enable signals: BWa, BWb, BWc, and BWd. Each controls a 9-bit segment of the 36-bit data bus, enabling granular 9-bit writes without requiring read-modify-write sequences or external masking logic.

Is CY7C1470V33 pin-compatible with standard ZBT SRAMs?

Yes - it is explicitly designed to be pin-compatible and functionally equivalent to industry-standard ZBT SRAMs, including identical pin assignments for CLK, CEN, WE, CE1–CE3, OE, and DQ buses. This allows drop-in replacement in existing ZBT-based designs with no layout changes required.
