Infineon Technologies CY7C1460KVE33-200AXC

Overview

CY7C1460KVE33 from Cypress Semiconductor is a 36-Mbit (1M × 36) synchronous pipelined SRAM with NoBL™ architecture, integrated ECC, 3.3-V core supply, 2.5/3.3-V I/O support, and 200-MHz operation (3.2-ns access time). It serves as a high-throughput memory buffer in network packet processors requiring zero-wait-state back-to-back read/write transitions.

For engineers reviewing the CY7C1460KVE33 datasheet, CY7C1460KVE33 pinout, CY7C1460KVE33 application, or CY7C1460KVE33 equivalent, key selection criteria include burst order configuration (linear/interleaved), byte-write granularity (BWa–BWd), synchronous self-timed write timing, JTAG boundary-scan capability, and ECC-enabled soft-error resilience in telecom infrastructure.

Technical Context

This SRAM implements fully registered pipelined operation: all address, control, and data inputs are latched on the rising edge of CLK (qualified by CEN), and all outputs are driven from output registers synchronized to the same clock edge. The internal NoBL logic eliminates bus turnaround latency between consecutive reads and writes.

Burst addressing is configurable via MODE pin (interleaved or linear), and on-chip ECC encodes/decodes parity across DQa–DQd and corresponding DQPa–DQPd lines to detect and correct single-bit errors. Write operations are self-timed and qualified by WE and four independent byte-write enables.

FAQ

What is the function of the MODE pin on CY7C1460KVE33?

The MODE pin is a strap input that configures burst addressing order: pulled HIGH (or left floating) selects interleaved burst mode; pulled LOW selects linear burst mode. It must be held static during operation and is sampled at power-up or reset. This setting directly determines how the internal address counter increments during burst reads/writes.

Does CY7C1460KVE33 support 2.5-V-only I/O operation?

Yes - VDDQ may be supplied at 2.5 V ± 0.2 V while maintaining full 200-MHz operation and compatibility with 2.5-V logic families. The device retains all timing specifications and ECC functionality under 2.5-V I/O conditions, enabling seamless integration with legacy FPGAs and ASICs.

How does the on-chip ECC interact with the DQP pins?

DQPa–DQPd are dedicated parity I/O pins paired one-to-one with DQa–DQd. During write, the ECC encoder generates 4 parity bits from 32 data bits and drives them onto DQPa–DQPd. During read, the decoder uses those parity bits to detect and correct single-bit errors in the 32-bit data word before output registration.

Can CY7C1460KVE33 operate without JTAG enabled?

Yes - JTAG is disabled by default at power-on. The TAP controller remains inactive unless the JTAG instruction register is loaded via TMS/TCK sequence. No external pull-ups or configuration fuses are required to disable boundary scan; normal memory operation proceeds independently of JTAG state.
