Infineon Technologies CY7C1460AV33-250AXCT

Overview

CY7C1460AV33-250AXCT from Cypress Semiconductor is a 3.3V, 1M × 36 (36 Mbit) synchronous pipelined SRAM with NoBL™ architecture, designed for high-throughput back-to-back read/write operations in network packet buffers and cache controllers. It supports 250 MHz bus operation with zero wait states, 2.6 ns clock-to-output delay, and byte-write capability via four synchronous BWa–BWd signals.

For engineers reviewing the CY7C1460AV33-250AXCT datasheet, CY7C1460AV33-250AXCT pinout, CY7C1460AV33-250AXCT application, or CY7C1460AV33-250AXCT equivalent, key selection criteria include burst mode support (linear/interleaved), synchronous self-timed write timing, JTAG boundary scan compliance, and compatibility with ZBT-style memory interfaces in telecom and FPGA-based systems.

Technical Context

The device implements fully registered pipelined operation: all address, control, and data inputs are latched on the rising edge of CLK, and all outputs pass through output registers synchronized to the same edge. Clock Enable (CEN) qualifies CLK, enabling cycle extension without deselection.

NoBL™ logic eliminates bus latency by enabling true consecutive read/write transitions - each clock cycle delivers valid data or accepts new write data, with no dead cycles. Internal burst logic supports both linear and interleaved addressing modes controlled by the MODE pin.

FAQ

What is the function of the MODE pin on CY7C1460AV33-250AXCT?

The MODE pin configures burst address sequencing: when tied to VDD or left floating, it enables interleaved burst order (optimal for cache line accesses); when tied to GND, it selects linear burst order (sequential addressing). This setting is sampled at power-up and remains static during operation unless reconfigured externally.

Does CY7C1460AV33-250AXCT support true dual-port operation?

No - it is a single-port synchronous SRAM with pipelined read/write capability. While it supports back-to-back read and write operations on consecutive clocks (NoBL™), it does not allow simultaneous read and write to different addresses like a true dual-port RAM. Address and control lines are shared, and write data overwrites read data if accessed on the same cycle.

How does the ZZ (sleep) mode reduce power consumption?

In ZZ mode, the device enters deep sleep with typical standby current ≤120 µA - a >99% reduction versus active operation (475 mA). All internal clocks and array activity halt, but address and data bus states are retained. Exit requires deasserting ZZ followed by two clock cycles before valid access; no initialization sequence is needed.

Can CY7C1460AV33-250AXCT be used with a 2.5 V I/O interface?

Yes - VDDQ supports 2.5 V ±0.2 V operation while maintaining 3.3 V core (VDD). I/O pins are fully compatible with 2.5 V LVTTL and SSTL-2 signaling standards. The device automatically adapts drive strength and threshold levels based on VDDQ voltage, eliminating level-shifter requirements in mixed-voltage systems.
