Infineon Technologies CY7C1460KVE25-167AXC

Overview

CY7C1460KVE25-167AXC 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 maximum access time, 2.5 V core/I/O supply, and supports zero-wait-state burst reads/writes in networking line cards requiring high-throughput packet buffering.

For engineers reviewing the CY7C1460KVE25-167AXC datasheet, CY7C1460KVE25-167AXC pinout, CY7C1460KVE25-167AXC application, or CY7C1460KVE25-167AXC equivalent, this device delivers deterministic timing for back-to-back read/write transitions, byte-selectable writes with BWa–BWd, synchronous self-timed writes, and JTAG-compliant boundary scan for production testability.

Technical Context

The CY7C1460KVE25-167AXC implements fully registered synchronous interfaces: all address, control, and data inputs are latched on the rising edge of CLK, and all outputs are driven from output registers clocked by the same edge. Its NoBL™ logic eliminates bus latency by enabling true back-to-back operations without wait states.

It integrates on-chip ECC encoding/decoding to correct single-bit errors and detect double-bit errors, reducing soft error rate (SER) in radiation-prone environments. Burst capability supports both linear and interleaved orders, and the ZZ sleep mode reduces power during idle cycles while retaining data.

FAQ

What is the function of the MODE pin on CY7C1460KVE25-167AXC?

The MODE pin selects between 1M × 36 and 2M × 18 memory organizations. When MODE = HIGH, the device operates in 1M × 36 mode (36-bit wide); when MODE = LOW, it configures as 2M × 18 (18-bit wide with extended depth). This selection is latched at power-up and remains static during operation.

Does CY7C1460KVE25-167AXC require external termination resistors on its data bus?

No. The device incorporates programmable output drive strength and on-die termination (ODT) support via internal impedance control circuitry. External termination is unnecessary when driving controlled-impedance PCB traces compliant with 50 Ω single-ended or 100 Ω differential routing guidelines.

How does the ZZ pin interact with CEN and chip enables during low-power operation?

ZZ is asynchronous and forces deep sleep regardless of CEN or CE states. When ZZ is asserted LOW, all internal clocks halt, I/Os enter high-Z, and core current drops below 50 µA. CEN and CE retain their last logic states but are ignored until ZZ returns HIGH and a valid CLK edge occurs.

Can CY7C1460KVE25-167AXC be used in place of CY7C1460KV25-167AXC?

Yes - the "E" suffix denotes enhanced version with identical pinout, timing, and functionality, plus improved ECC implementation and updated AC/DC specifications per Rev. *J datasheet. Migration requires no hardware or firmware changes and is supported for new designs and drop-in replacements.
