Infineon Technologies CY7C1462AV25-200AXCT

Overview

CY7C1462AV25-200AXCT from Cypress Semiconductor is a 36-Mbit (2M × 18) synchronous pipelined SRAM with No Bus Latency™ (NoBL™) architecture, designed for high-throughput memory subsystems in network switches, baseband processors, and packet buffering applications. It operates at 200 MHz with zero wait states, features 2.5V core/2.5V–1.8V I/O supplies, 3.2 ns clock-to-output delay, and supports linear or interleaved burst modes via MODE pin configuration.

For engineers reviewing the CY7C1462AV25-200AXCT datasheet, CY7C1462AV25-200AXCT pinout, CY7C1462AV25-200AXCT application, or CY7C1462AV25-200AXCT equivalent, this device delivers deterministic pipelined read/write timing, byte-selectable writes with BWa–BWb, synchronous self-timed write control, and JTAG boundary-scan support - critical for high-speed data path integrity and system-level debugability.

Technical Context

The CY7C1462AV25-200AXCT implements fully registered synchronous interfaces: all address, control, and data inputs are latched on the rising edge of CLK (qualified by CEN), and all outputs pass through output registers synchronized to the same edge. Its NoBL™ logic enables true back-to-back Read/Write operations without bus latency, eliminating pipeline stalls during mixed-access patterns.

It integrates three synchronous chip enables (CE1 active-low, CE2 active-high, CE3 active-low) for flexible bank decoding, asynchronous OE for output enable control, and ZZ sleep mode for low-power standby. Burst addressing is managed via ADV/LD, supporting both linear and interleaved orders selected by the MODE strap pin - directly configurable at power-up without runtime reconfiguration.

FAQ

What is the function of the MODE pin, and how does it affect burst behavior?

The MODE pin is a static strap input that configures burst order at power-up: tied HIGH for interleaved burst (e.g., 0,2,4,6,1,3,5,7), LOW for linear burst (e.g., 0,1,2,3,4,5,6,7). It must remain stable during operation; floating defaults to HIGH. This setting directly determines address sequence generation during burst reads/writes and affects compatibility with CPU or DMA burst protocols.

Can CY7C1462AV25-200AXCT operate with 1.8V I/O while maintaining 2.5V core voltage?

Yes - VDDQ may be independently supplied at 1.8 V while VDD remains at 2.5 V. This allows direct interfacing with 1.8V FPGA I/O banks or ASIC logic without level shifters. The datasheet specifies valid 1.8V operation across commercial temperature range (0°C to +70°C) with guaranteed timing parameters including 3.2 ns tCO.

How does the ZZ sleep mode interact with clock and chip enable signals?

ZZ is asynchronous and active-high: asserting ZZ places the device in low-power sleep regardless of CLK, CEN, or CE states. Data is retained, and wake-up occurs within 100 ns of ZZ deassertion. Unlike CEN suspension, ZZ disables internal clocks and reduces current to ≤120 mA - making it suitable for deep power-down between traffic bursts.

Is the 100-pin TQFP package RoHS-compliant and lead-free?

Yes - the "XCT" suffix denotes JEDEC-standard lead-free 100-pin TQFP packaging, fully compliant with RoHS Directive 2011/65/EU. Cypress documentation confirms matte tin finish, Pb-free solderability, and qualification per J-STD-020 moisture sensitivity level 3 (MSL3) for surface-mount assembly.
