Detailed Description

72 Mbit NoBL synchronous SRAM, 2M x 36 organization, parallel interface, 2.5 V supply, 133 MHz clock, 6.5 ns access, commercial temperature range, 100‑pin TQFP package. RoHS3-compliant, surface-mount, tape-and-reel.

Key Features

Memory size: 72 Mbit (2M x 36)

Interface: Parallel, synchronous SDR (NoBL architecture)

Clock frequency: up to 133 MHz

Access time: 6.5 ns typical at rated conditions

Supply voltage: 2.375 V to 2.625 V (2.5 V nominal)

Operating temperature: 0°C to 70°C (TA)

Package: 100‑TQFP (14 x 20 mm), surface mount

RoHS: RoHS3 compliant, lead-free plating

Series: NoBL (No Bus Latency) family

Mounting: Tape & Reel (TR) for automated assembly

Base product number: CY7C1471

Key Advantages

NoBL (No Bus Latency) design reduces bus turnaround penalties for faster read/write switching

High bandwidth at 133 MHz for latency-sensitive buffering

Wide 36-bit data bus supports network and telecom payloads efficiently

Stable 2.5 V operation for lower power vs. 3.3 V SRAMs

Mature ecosystem with pinand timing-compatible family variants

Proven reliability from Cypress/Infineon with strong long-term availability support

Packaging

Shipment packaging: Tape & Reel (TR) for pick-and-place

IC package type: 100‑TQFP (also referenced as 100‑LQFP), body size approx. 14 x 20 mm

Pin count and configuration: 100 leads; includes a 36‑bit data bus (DQ[0:35]), address bus, clock, chip enable, output enable, write enable, byte write enables, burst/advance controls, and parity/controls depending on exact pinout; standard synchronous SRAM signal set

Materials: Molded epoxy body, copper leadframe with lead-free matte tin plating; RoHS3 compliant

Mounting: Surface-mount on standard FR‑4 PCBs

Thermal characteristics: Commercial temperature grade (0°C to 70°C); no exposed pad; ensure adequate airflow and copper area for heat spreading under high-frequency operation

Electrical properties: 2.5 V nominal supply (2.375–2.625 V), synchronous SDR timing, 133 MHz clock capability, low skew clocking; follow datasheet for input levels, timing, and current consumption

Lifecycle

Current status: Widely used in networking/telecom and embedded systems; availability may vary by speed grade and package

Nearing discontinuation: Not indicated for this specific suffix at the time of writing, but lifecycle can differ by variant; confirm with our sales team for the latest status

Equivalent or alternative models (verify pinout, timing, voltage, and temperature before use):

- Same family, different options:

- CY7C1471V25-167AXCT (higher speed grade, same voltage/package)

- CY7C1471V25-133AXC (tray packaging instead of reel)

- CY7C1471V25-xxxA?C/xxxA?I (suffixes vary by speed grade and temperature range; C = commercial, I = industrial; T = tape & reel)

- Cross-vendor ZBT/NoBL-type 2.5 V synchronous SRAM, 2M x 36:

- Renesas (IDT) 71V67603 (ZBT, 2M x 36, 2.5 V; check exact speed/packaging)

- ISSI IS61/IS62 series (e.g., IS61VPS25636, 2M x 36, 2.5 V; confirm variant)

- GSI Technology GS81/GS83 series (NoBL/ZBT, 2M x 36, 2.5 V; confirm part)
