Infineon Technologies CY7C1460KV25-167BZXI

Overview

CY7C1460KV25-167BZXI from Cypress Semiconductor is a 36-Mbit synchronous pipelined SRAM with NoBL™ architecture and on-chip ECC, configured as 1M × 36 or 2M × 18. It operates at 167 MHz with 3.4 ns max access time, 2.5 V core/I/O supply, and supports zero-wait-state back-to-back read/write in high-throughput networking buffers and packet processors.

For engineers reviewing the CY7C1460KV25-167BZXI datasheet, CY7C1460KV25-167BZXI pinout, CY7C1460KV25-167BZXI application, or CY7C1460KV25-167BZXI equivalent, this device delivers deterministic timing, byte-write granularity, synchronous self-timed writes, JTAG boundary scan, and ECC-enabled soft-error resilience for mission-critical memory subsystems.

Technical Context

The CY7C1460KV25-167BZXI implements fully registered pipelined operation: all address, control, and data inputs are latched on the rising edge of CLK, and all outputs are driven from output registers synchronized to CLK. Its NoBL™ logic eliminates bus latency by enabling consecutive read/write cycles without wait states.

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

FAQ

What is the function of the MODE pin on CY7C1460KV25-167BZXI?

The MODE pin configures burst addressing order: logic HIGH selects interleaved burst (e.g., for PowerPC-compatible systems), while logic LOW selects linear burst (e.g., for ARM or x86 hosts). It is sampled at power-up and remains static during operation; changing it mid-operation is undefined and unsupported.

Does CY7C1460KV25-167BZXI require external termination resistors on DQ/DQP lines?

No external termination is required. The device integrates programmable output drive strength and on-die termination (ODT) control via internal register settings, supporting impedance-matched signaling into 50 Ω transmission lines without discrete resistors-reducing BOM count and layout complexity.

How does the ZZ sleep mode interact with the CEN pin?

ZZ and CEN operate independently: ZZ places the core in ultra-low-power retention state (≤10 µA ICC), while CEN only gates the clock path. When both are active (ZZ = LOW, CEN = HIGH), the device enters deep sleep with clock disabled and memory retained; exiting requires ZZ deassertion followed by CEN assertion and CLK restart per datasheet timing tZZR and tCER.

Can CY7C1460KV25-167BZXI be used in a 2M × 18 configuration without hardware modification?

Yes-the same physical device supports both 1M × 36 and 2M × 18 modes via address pin mapping: A18–A19 become address bits in ×18 mode, while A17–A19 are unused in ×36 mode. No strapping resistors or configuration pins are needed; mode is determined solely by how the host controller drives A[19:0] and interprets DQ[35:0] as two 18-bit words.
