Infineon Technologies CY7C1462KV25-200AXC

Overview

CY7C1462KV25-200AXC from Cypress Semiconductor is a 36-Mbit (2M × 18) synchronous pipelined SRAM with NoBL™ architecture and on-chip ECC, designed for high-throughput memory subsystems in networking and telecom infrastructure. It operates at 200 MHz with zero wait states, supports synchronous self-timed writes, features byte-write capability via BWa–BWb, and uses 2.5 V core/I/O supplies.

For engineers reviewing the CY7C1462KV25-200AXC datasheet, CY7C1462KV25-200AXC pinout, CY7C1462KV25-200AXC application, or CY7C1462KV25-200AXC equivalent, this device is selected for systems requiring deterministic latency, burst read/write coherency, ECC-enabled data integrity, and JEDEC-standard 100-pin TQFP packaging with JTAG boundary scan support.

Technical Context

This SRAM implements fully registered pipelined operation: all address, control, and data inputs are latched on the rising edge of CLK, and all outputs are driven through output registers synchronized to CLK. The internal NoBL™ logic eliminates bus latency by enabling true back-to-back read/write cycles without wait states.

It integrates on-chip ECC encoding/decoding for single-bit error correction and double-bit error detection, reducing soft error rate in radiation-sensitive environments. Burst capability supports both linear and interleaved orders, and the ZZ sleep mode reduces power during idle periods while preserving data.

FAQ

What is the function of the ADV/LD pin in burst-mode operation?

The ADV/LD pin controls the internal address counter behavior: when HIGH and CEN is active, it advances the counter to the next sequential address for burst reads/writes; when LOW, it loads a new starting address from A[18:0]. This enables seamless switching between burst and random access without external address generation logic.

Does CY7C1462KV25-200AXC support interleaved burst addressing?

Yes - the device supports both linear and interleaved burst orders, selectable via the MODE pin. Interleaved mode maps addresses to optimize cache-line access patterns in CPU-centric systems, while linear mode suits packet-oriented streaming applications like Ethernet frame buffering.

How does the ZZ (sleep) mode affect data retention and wake-up latency?

In ZZ mode, core power drops to ≤50 µA while retaining full memory contents; wake-up requires only one CLK cycle after ZZ deassertion before valid data appears on DQ pins. No refresh or reinitialization is needed, making it ideal for low-duty-cycle control-plane buffers.

Can the ECC be disabled to use all bits as user data?

No - ECC is hardwired and always active; the 4 parity bits (DQPa–DQPb) are dedicated and cannot be repurposed. The device delivers 18-bit data width with integrated SEC-DED protection - no configuration register or pin exists to disable ECC functionality.
