Infineon Technologies CY7C1460AV33-250AXC

Overview

CY7C1460AV33 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 networking and telecom data path buffers. It supports 250 MHz bus operation with zero wait states, features 2.6 ns clock-to-output time, fully registered I/O, and byte-write capability via four BW inputs (BWa–BWd).

For engineers reviewing the CY7C1460AV33 datasheet, CY7C1460AV33 pinout, CY7C1460AV33 application, or CY7C1460AV33 equivalent, key selection criteria include its 100-pin TQFP or 165-ball FBGA packaging, synchronous self-timed write control, JTAG boundary scan compliance, and compatibility with ZBT-style system interfaces requiring deterministic latency.

Technical Context

The device implements a fully synchronous, rising-edge-triggered interface with three chip enables (CE1 low, CE2 high, CE3 low) and asynchronous OE for output tristate control. All address, data, and control signals pass through input registers synchronized to CLK, while outputs are registered and driven on the next rising edge.

NoBL™ logic eliminates bus latency by enabling true consecutive read/write cycles without turnaround overhead. Internal burst logic supports linear or interleaved addressing modes controlled by the MODE pin, and ZZ sleep mode reduces standby current to 120 mA while preserving data.

FAQ

What is the function of the MODE pin on CY7C1460AV33?

The MODE pin selects burst addressing order: when tied to VDD or left floating, it enables interleaved burst mode; when grounded, it configures linear burst mode. This setting determines how consecutive addresses increment during burst reads/writes and must match the memory controller's expectation to avoid data misalignment.

Can CY7C1460AV33 operate with 2.5 V I/O voltage while maintaining 3.3 V core supply?

Yes - VDDQ supports 2.5 V ±0.2 V operation independent of the 3.3 V VDD core supply, allowing direct interfacing with 2.5 V logic families without level shifters. DC characteristics specify valid timing margins under this mixed-voltage condition per Table 10 of the datasheet.

How does the ZZ (sleep) mode affect data retention and wake-up latency?

In ZZ mode (pin driven low), the device enters deep sleep with 120 mA standby current while retaining all stored data. Wake-up occurs on the first valid CLK edge after ZZ is deasserted; no additional initialization or delay is required, and the next access proceeds normally within one clock cycle.

Is CY7C1460AV33 pin-compatible with ZBT SRAMs such as IDT72V2115?

It is functionally equivalent and pin-compatible with ZBT devices in 100-pin TQFP packaging, sharing identical signal names, placement, and timing behavior. However, CY7C1460AV33 adds enhancements including ZZ sleep mode, JTAG boundary scan, and tighter 2.6 ns access time - requiring verification of OE masking and CEN interaction in legacy ZBT designs.
