Infineon Technologies CY7C1460KV25-250AXC

Overview

CY7C1460KV25-250AXC from Cypress Semiconductor is a 36-Mbit (1M × 36) synchronous pipelined SRAM with NoBL™ architecture, ECC support, and 2.5 V core/I/O supply. It delivers zero-wait-state 250 MHz bus operation, 2.5 ns clock-to-output timing, and full input/output registration for true back-to-back read/write throughput in high-speed packet buffering and network switching applications.

For engineers reviewing the CY7C1460KV25-250AXC datasheet, CY7C1460KV25-250AXC pinout, CY7C1460KV25-250AXC application, or CY7C1460KV25-250AXC equivalent, key selection criteria include burst mode compatibility (linear/interleaved), byte-write granularity (BWa–BWd), on-chip ECC correction capability, and JEDEC-standard 100-pin TQFP packaging with ZZ sleep mode support.

Technical Context

This SRAM implements fully registered synchronous interface logic: all address, control, and data inputs are latched on the rising edge of CLK, and all outputs pass through output registers synchronized to CLK. The NoBL™ architecture eliminates bus latency by enabling consecutive read/write operations without wait states via internal self-timed output buffer control and synchronous self-timed write circuitry.

It integrates on-chip ECC encoding/decoding for single-bit error correction and double-bit error detection, reducing soft error rate (SER) in radiation-sensitive environments. Burst capability supports both linear and interleaved orders, while three chip enables (CE1, CE2, CE3) and asynchronous OE enable flexible bank selection and output three-state management.

FAQ

Is CY7C1460KV25-250AXC pin-compatible with ZBT™ SRAMs?

Yes, it is pin-compatible and functionally equivalent to ZBT™ SRAMs per Cypress documentation. All control, address, and data pins map identically-including CE1/CE2/CE3, BWa–BWd, ADV/LD, and MODE-allowing direct replacement in existing ZBT-based designs without PCB modification.

What is the role of the MODE pin in CY7C1460KV25-250AXC?

The MODE pin selects burst order: logic HIGH configures linear burst addressing, while logic LOW selects interleaved burst addressing. This setting is sampled at device power-up or reset and remains static during operation, aligning with cache-line fetch patterns used in DSP and network processor interfaces.

How does the ZZ sleep mode reduce power consumption?

When ZZ is asserted LOW, the device enters low-power sleep mode with typical standby current below 100 µA. Internal clocks and array biasing are gated, but address and data bus states are retained. Exit time is ≤100 ns, enabling rapid resumption of full-speed operation without reinitialization.

Can CY7C1460KV25-250AXC operate in 2M × 18 configuration?

No. CY7C1460KV25-250AXC is fixed to 1M × 36 organization. The 2M × 18 variant is the pin-compatible CY7C1462KV25-250AXC, which uses different byte-write pin mapping (BWa–BWb only) and lacks DQPc/DQPd parity lines. Configuration is hardwired by internal metal mask, not software-selectable.
