Infineon Technologies CY7C1460KV33-200AXCT

Overview

CY7C1460KV33 from Cypress Semiconductor is a 36-Mbit (1M × 36) synchronous pipelined SRAM with NoBL™ architecture, ECC support, 3.3-V core supply, 200-MHz operation (3.2-ns access), and JEDEC-standard 100-pin TQFP packaging. It enables zero-wait-state back-to-back read/write in high-throughput networking buffers and packet processors.

For engineers reviewing the CY7C1460KV33 datasheet, CY7C1460KV33 pinout, CY7C1460KV33 application, or CY7C1460KV33 equivalent, key selection criteria include burst order configuration (linear/interleaved), byte-write select mapping (BWa–BWd), synchronous self-timed write timing, on-chip ECC correction capability, and CEN-controlled clock gating behavior.

Technical Context

This SRAM implements fully registered synchronous I/O with rising-edge clock capture for all control, address, and data signals. Its NoBL™ logic eliminates bus turnaround latency by enabling consecutive read/write cycles without wait states, supported by internal burst counters and ADV/LD-controlled address sequencing.

The device integrates on-chip ECC encoding/decoding for single-bit error correction and double-bit error detection, reducing soft error rate in radiation-sensitive environments. It supports both linear and interleaved burst orders via the MODE strap pin and provides synchronous tristate control of DQ/DQP lines during write data phases.

FAQ

What is the function of the MODE pin on CY7C1460KV33?

The MODE pin selects burst address order: pulled HIGH (or left floating) configures interleaved burst mode; pulled LOW selects linear burst mode. It must remain static during operation. Interleaved mode supports cache-line access patterns common in processor interfaces, while linear mode suits sequential streaming applications like video frame buffering.

How does the ZZ sleep mode operate and what is its current draw?

Asserting ZZ LOW places the device into low-power sleep mode, reducing ICC to less than 100 µA while retaining all stored data. The device wakes on the next valid CLK edge after ZZ returns HIGH. This mode is asynchronous to clock and independent of CEN, enabling rapid entry/exit without disrupting timing sequences.

Can CY7C1460KV33 interface directly with a 2.5-V FPGA I/O bank?

Yes. VDDQ supports 2.5-V operation independently of the 3.3-V VDD core supply. When VDDQ = 2.5 V, all DQ/DQP and BW pins operate at 2.5-V logic levels with compatible voltage thresholds, enabling direct connection to 2.5-V FPGA I/O without level shifters or external resistors.

What happens to outputs during a write cycle when OE is asserted LOW?

Outputs are automatically tristated during the data portion of any write sequence - even if OE is held LOW. This prevents bus contention and eliminates need for external OE timing control. Tristate behavior is enforced synchronously by internal logic and overrides OE state during write data windows.
