Infineon Technologies CY7C1474V33-200BGC

Overview

CY7C1474V33 from Infineon Technologies (formerly Cypress) is a 72-Mbit synchronous pipelined SRAM with NoBL™ architecture, configured as 1M × 72, supporting 200 MHz zero-wait-state bus operation. It features fully registered I/O, byte-write capability across eight 9-bit groups (BWSa–BWSh), 3.3 V core supply with 3.3 V/2.5 V I/O support, and JTAG boundary scan compliance. Used in high-throughput network packet buffers and telecom line card data staging.

For engineers reviewing the CY7C1474V33 datasheet, CY7C1474V33 pinout, CY7C1474V33 application, or CY7C1474V33 equivalent, key selection criteria include burst mode compatibility (linear/interleaved), ZZ sleep mode implementation, 209-ball FBGA mechanical fit, and synchronous self-timed write timing at 200 MHz.

Technical Context

This SRAM implements a true pipelined read/write architecture with No Bus Latency™ logic, enabling back-to-back operations without wait states. All inputs and outputs are edge-triggered by the rising clock edge, and output enable is asynchronous while output drivers are synchronously tristated during writes to prevent bus contention.

The device supports three chip enables (CE1–CE3) for bank selection, clock enable (CEN) for cycle suspension, and eight independent byte write selects (BWSa–BWSh) for granular 9-bit writes. Burst addressing follows either linear or interleaved order, controlled by the MODE pin.

FAQ

What is the correct handling for the ZZ pin on CY7C1474V33?

The ZZ pin (Ball P6) must be externally tied to ground per documented errata on page 35 of the datasheet. Leaving it floating or pulling high may cause undefined sleep behavior or increased standby current. This requirement is mandatory for functional reliability and is not optional - it applies regardless of whether sleep mode is actively used in the design.

Does CY7C1474V33 support both linear and interleaved burst orders?

Yes. The MODE pin selects burst order: logic high enables linear burst, logic low enables interleaved burst. This matches standard ZBT SRAM behavior and allows seamless integration with processors or FPGAs that require either addressing scheme for cache line or DMA transfers without software modification.

Can CY7C1474V33 operate with 2.5 V I/O while using 3.3 V core supply?

Yes. The device supports independent 3.3 V core (VDD) and 2.5 V I/O (VDDQ) supplies. VDDQ pins must be supplied at 2.5 V ±0.2 V, and all DQ/DQP pins become 2.5 V tolerant. This enables direct interfacing with 2.5 V FPGA I/O banks while maintaining full 200 MHz timing performance.

Is JTAG boundary scan supported in all operating modes?

Yes. IEEE 1149.1 boundary scan remains fully functional during active memory operation, standby (CEN deasserted), and ZZ sleep mode. TAP signals (TCK, TMS, TDI, TDO) operate independently of memory control pins, allowing in-system test access without halting system operation.
