Renesas 71T75602S150PFG

Overview

71T75602S150PFG from IDT (now Renesas) is a 2.5V synchronous ZBT™ SRAM with 512K × 36-bit organization (18 Mbit), 200 MHz operation, 3.2 ns clock-to-data access, zero bus turnaround architecture, and JEDEC-standard 100-pin TQFP packaging. It serves as a high-bandwidth buffer in network packet processors and telecom line cards requiring pipelined burst reads/writes.

For engineers reviewing the 71T75602S150PFG datasheet, 71T75602S150PFG pinout, 71T75602S150PFG application, or 71T75602S150PFG equivalent, key selection criteria include ZBT™ burst timing compliance, 2.5V I/O supply (VDDQ) decoupling requirements, industrial temperature support (–40°C to +85°C), and JTAG IEEE 1149.1 test interface validation for production testability.

Technical Context

The 71T75602S150PFG implements a fully synchronous, pipelined architecture with positive-edge-triggered address/control/data registers. Its on-chip burst counter supports 4-word linear or interleaved sequences controlled by the LBO pin, and ADV/LD determines whether external addresses are loaded or internal counters advanced.

ZBT™ operation eliminates dead cycles between read/write transitions via internally synchronized output buffer enable-removing need for OE timing control-and uses three chip enables (CE1/CE2/CE2) with two-cycle deselect latency. Sleep mode is entered synchronously via high-ZZ input, guaranteeing data retention at minimal power.

FAQ

What is the memory organization and density of the 71T75602S150PFG?

The 71T75602S150PFG is configured as 512K × 36-bit, delivering 18,874,368 bits (18 Mbit) of synchronous SRAM. It supports pin-selectable reconfiguration to 1M × 18-bit mode. This dual-organization flexibility allows system designers to optimize data bus width versus address space based on controller interface constraints without changing the physical component.

Does the 71T75602S150PFG support industrial temperature operation?

Yes, the 71T75602S150PFG is rated for industrial temperature operation from –40°C to +85°C. This specification is validated across all electrical parameters-including 200 MHz timing, ZBT™ burst behavior, and JTAG functionality-and applies to the S150PFG suffix variant, which denotes the industrial-grade 100-pin TQFP package.

How does the ZBTTM feature improve system performance in the 71T75602S150PFG?

The ZBTTM (Zero Bus Turnaround) feature in the 71T75602S150PFG eliminates idle cycles between successive read and write operations. By internally synchronizing output buffer enable and using pipelined registers, the 71T75602S150PFG achieves continuous bus utilization-reducing effective latency by up to one clock cycle per transition compared to conventional synchronous SRAMs.

What is the function of the ADV/LD and LBO pins on the 71T75602S150PFG?

On the 71T75602S150PFG, ADV/LD controls burst counter behavior: sampled LOW at rising CLK, it loads a new external address; sampled HIGH, it advances the internal burst counter. LBO selects burst order-LOW enables linear (0,1,2,3), HIGH enables interleaved (0,2,1,3)-and must remain static during burst execution to prevent undefined addressing.

Can the 71T75602S150PFG be used with a 3.3V system controller?

The 71T75602S150PFG requires 2.5V ±5% for both VDD (core) and VDDQ (I/O). Direct connection to a 3.3V controller violates VIH limits and risks damage. A level-shifting interface-such as dual-supply translators (e.g., TXB0108) or resistor-divider networks with appropriate drive strength-is mandatory to ensure safe, compliant signal translation between 3.3V logic and the 71T75602S150PFG's 2.5V I/O domain.
