Cypress Semiconductor Corp CY7C1460KV25-200BZI

Overview

CY7C1460KV25-200BZI from Cypress Semiconductor is a 36-Mbit (1M × 36) synchronous pipelined SRAM with NoBL™ architecture, 2.5 V core/I/O supply, on-chip ECC, and 200 MHz operation (3.2 ns clock-to-output). It supports zero-wait-state back-to-back read/write cycles in high-throughput networking and packet buffering applications.

For engineers reviewing the CY7C1460KV25-200BZI datasheet, CY7C1460KV25-200BZI pinout, CY7C1460KV25-200BZI application, or CY7C1460KV25-200BZI equivalent, key selection criteria include burst mode support (linear/interleaved), byte-write capability with BWa–BWd controls, synchronous self-timed writes, JTAG boundary scan compliance, and TQFP-100 packaging with ZZ sleep mode.

Technical Context

This SRAM implements fully registered pipelined I/O with all inputs and outputs synchronized to the rising edge of CLK, qualified by CEN. Its NoBL™ logic enables true back-to-back operations without bus latency, eliminating wait states across consecutive reads and writes.

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. Burst addressing supports both linear and interleaved orders, controlled via MODE and ADV/LD signals.

FAQ

What is the function of the MODE pin on CY7C1460KV25-200BZI?

The MODE pin selects burst addressing order: logic HIGH configures linear burst (sequential increment), logic LOW selects interleaved burst (bit-swapped increment). This setting is latched at power-up or reset and determines how ADV/LD advances the internal address counter during burst accesses.

Does CY7C1460KV25-200BZI require external termination resistors on DQ lines?

No. The device features internally calibrated output drivers with programmable drive strength, eliminating the need for external series or parallel termination. Layout guidelines recommend 50 Ω controlled-impedance traces and proper VDDQ/VSS decoupling per the datasheet's PCB design section.

How does the ZZ sleep mode interact with data retention?

In ZZ mode, the device disables internal clocks and analog circuitry while maintaining SRAM cell bias, retaining all stored data indefinitely as long as VDD and VDDQ remain within specification (2.375 V to 2.625 V). Exit time from ZZ is 20 ns maximum, with no refresh required.

Can CY7C1460KV25-200BZI operate in 2M × 18 configuration?

No. CY7C1460KV25-200BZI is strictly a 1M × 36 device. The 2M × 18 configuration is supported only by CY7C1462KV25 variants (e.g., CY7C1462KV25-200BZI), which have different pinouts, byte-write grouping (BWa–BWb only), and address mapping.
