Infineon Technologies CY7C1460KVE25-200BZXI

Overview

CY7C1460KVE25-200BZXI from Cypress Semiconductor is a 36-Mbit (1M × 36) synchronous pipelined SRAM with NoBL™ architecture and on-chip ECC, designed for high-throughput memory buffering in network packet processors and telecom line cards. It operates at 200 MHz with 3.2 ns clock-to-output time, uses 2.5 V core/I/O supplies, and supports byte-write and linear/interleaved burst modes.

For engineers reviewing the CY7C1460KVE25-200BZXI datasheet, CY7C1460KVE25-200BZXI pinout, CY7C1460KVE25-200BZXI application, or CY7C1460KVE25-200BZXI equivalent, key selection criteria include ECC-enabled soft-error resilience, zero-wait-state back-to-back read/write capability, 100-pin TQFP package compatibility, and synchronous self-timed write timing compliance.

Technical Context

This SRAM implements fully registered pipelined operation: all address, control, and data inputs are latched on the rising edge of CLK; all outputs are driven from output registers synchronized to CLK. Internal self-timed output buffer control eliminates asynchronous OE dependency for clean bus handoff.

The device integrates on-chip ECC encoding/decoding logic that detects and corrects single-bit errors per 36-bit word, reducing soft error rate (SER) in radiation-prone environments. Burst logic supports both linear and interleaved address sequences, with ADV/LD controlling counter advance or new address load under CEN qualification.

FAQ

What is the function of the MODE pin on CY7C1460KVE25-200BZXI?

The MODE pin selects burst address sequence type: logic HIGH configures linear burst order, while logic LOW selects interleaved burst order. This setting is sampled synchronously on the rising edge of CLK when CEN is active LOW, and must be stable before burst initiation to ensure correct address generation during burst reads/writes.

Does CY7C1460KVE25-200BZXI require external termination resistors on its DQ lines?

No external termination resistors are required on DQ lines because the device incorporates programmable output drive strength and on-die impedance control calibrated to match standard 50 Ω transmission lines. Layout guidelines specify controlled-impedance routing and stub-free topology, but no discrete termination components are needed per the datasheet AC specifications.

How does the ZZ (sleep) mode affect power consumption and wake-up latency?

In ZZ mode, core and I/O power consumption drops to ≤5 mA (typical), reducing standby power by >95% versus active operation. Wake-up latency is one clock cycle: asserting CEN LOW and driving CLK resumes operation immediately, with valid data available on the next rising CLK edge - no initialization or calibration delay is incurred.

Can CY7C1460KVE25-200BZXI operate in 2M × 18 mode?

No - CY7C1460KVE25-200BZXI is factory-configured for 1M × 36 organization only. The CY7C1462KVE25 variant supports 2M × 18; pinouts, address mapping, and BW signal count differ between the two families, making them functionally distinct and not software- or hardware-interchangeable.
