Renesas IDT71T75602S200PFGI

Overview

IDT71T75602S200PFGI from Renesas Electronics is a 2.5V synchronous ZBT™ SRAM with 512K × 36-bit organization (18 Mbit), 200 MHz clock speed, 3.2 ns clock-to-data access, zero bus turnaround (ZBT) architecture, and pipelined burst outputs. It serves as high-speed buffer memory in network packet processors and telecom line cards requiring deterministic latency and seamless read/write transitions.

For engineers reviewing the IDT71T75602S200PFGI datasheet, IDT71T75602S200PFGI pinout, IDT71T75602S200PFGI application, or IDT71T75602S200PFGI equivalent, key selection criteria include ZBT timing compliance, 4-word interleaved/linear burst capability, JTAG IEEE 1149.1 support, industrial temperature range (–40°C to +85°C), and TQFP-100 packaging with 2.5V I/O supply (VDDQ).

Technical Context

The IDT71T75602S200PFGI implements a fully synchronous, clock-edge-triggered architecture with input/output registers aligned to the rising edge of CLK. Its internal burst counter supports 4-word sequences controlled by ADV/LD and LBO, enabling linear or interleaved addressing without external logic.

ZBT operation eliminates dead cycles between consecutive reads and writes via internally synchronized output enable and pipelined data paths. The device uses three chip enables (CE1, CE2, CE2) for depth expansion and includes a dedicated ZZ sleep mode pin for low-power retention.

FAQ

What is the memory organization supported by the IDT71T75602S200PFGI?

The IDT71T75602S200PFGI supports a 512K × 36-bit configuration (18 Mbit total), and can be configured as 1M × 18-bit via pin strapping. This dual-mode flexibility allows system designers to optimize data bus width and address space based on controller interface requirements while using the same IDT71T75602S200PFGI footprint.

Does the IDT71T75602S200PFGI support burst read and write operations?

Yes, the IDT71T75602S200PFGI features an on-chip 4-word burst counter controlled by ADV/LD and LBO pins. It supports both linear and interleaved burst sequences, enabling efficient sequential access without repeated address setup - a key advantage for packet payload handling and FFT data movement in the IDT71T75602S200PFGI.

What is the purpose of the ZZ pin on the IDT71T75602S200PFGI?

The ZZ pin on the IDT71T75602S200PFGI is a synchronous sleep mode input. When driven HIGH, it gates the internal clock and places the device in its lowest power-consumption state while retaining memory contents. This feature is essential for power-aware designs such as battery-backed telecom modules where the IDT71T75602S200PFGI must maintain data integrity during standby.

How does the ZBTTM architecture improve system performance in the IDT71T75602S200PFGI?

The ZBTTM (Zero Bus Turnaround) architecture in the IDT71T75602S200PFGI eliminates dead cycles between consecutive read and write operations by synchronizing output enable internally. This allows immediate bus direction reversal - critical for high-efficiency packet buffering where the IDT71T75602S200PFGI sustains full bandwidth during mixed-access workloads without pipeline stalls.

Is JTAG boundary scan supported on the IDT71T75602S200PFGI, and what standard does it follow?

Yes, the IDT71T75602S200PFGI includes a fully compliant IEEE 1149.1 JTAG boundary scan interface with TMS, TDI, TCK, TDO, and optional TRST pins. This enables automated PCB interconnect testing and in-system debug - a verified capability documented in the IDT71T75602S200PFGI datasheet and used in production test flows for telecom hardware.
