Renesas 71T75602S133PFG

Overview

71T75602S133PFG from Renesas Electronics is a 2.5V synchronous ZBT™ SRAM with 512K × 36-bit organization (18 Mbit), supporting 200 MHz operation (3.2 ns clock-to-data access), zero bus turnaround, pipelined outputs, and JTAG IEEE 1149.1 compliance - deployed in high-speed networking packet buffers and telecom line-card control planes.

For engineers reviewing the 71T75602S133PFG datasheet, 71T75602S133PFG pinout, 71T75602S133PFG application, or 71T75602S133PFG equivalent, key selection criteria include burst mode timing (linear/interleaved), byte-write granularity (BW1–BW4), industrial temperature support (–40°C to +85°C), TQFP-100 packaging, and ZBT™ bus efficiency for backplane interface buffering.

Technical Context

The 71T75602S133PFG implements a fully synchronous, rising-edge-triggered architecture with registered address, data, and control paths. Its internal burst counter enables 4-word interleaved or linear sequences controlled by LBO, while ADV/LD determines whether external addresses load or internal counters increment.

ZBTTM eliminates dead cycles between read/write transitions via internally synchronized output buffer enable (no OE timing constraints) and supports depth expansion using three chip enables (CE1, CE2, CE2). Sleep mode (ZZ) gates CLK for low-power retention, and JTAG boundary scan provides testability without requiring external logic.

FAQ

What is the maximum operating frequency of the 71T75602S133PFG?

The 71T75602S133PFG operates at up to 200 MHz, achieving a 3.2 ns clock-to-data access time. This specification is guaranteed across the full industrial temperature range (–40°C to +85°C) and 2.5 V ±5% supply conditions, enabling deterministic timing in real-time packet processing systems.

Does the 71T75602S133PFG support burst read and write operations?

Yes, the 71T75602S133PFG supports 4-word burst operations in both linear and interleaved sequences, selected by the LBO pin. Burst mode is initiated by asserting ADV/LD = HIGH after initial address load, and the internal counter advances automatically - reducing address bus traffic and improving effective bandwidth.

How does the ZBTTM feature improve system performance in the 71T75602S133PFG?

ZBTTM (Zero Bus Turnaround) in the 71T75602S133PFG eliminates dead cycles between alternating read and write operations. By synchronizing output buffer enable internally, the 71T75602S133PFG allows immediate bus direction reversal - increasing sustained throughput by up to 20% compared to conventional SSRAMs in burst-intensive applications.

What are the voltage requirements for VDD and VDDQ on the 71T75602S133PFG?

The 71T75602S133PFG requires VDD = 2.5 V ±5% for core logic and VDDQ = 2.5 V ±5% for I/O drivers. These supplies may be derived from separate regulators to minimize noise coupling; VIH thresholds are referenced to respective supply rails (VDD for controls, VDDQ for I/O), ensuring robust noise margins.

Is JTAG boundary scan supported on the 71T75602S133PFG, and what pins are used?

Yes, the 71T75602S133PFG implements IEEE 1149.1-compliant JTAG boundary scan using TMS, TDI, TCK, and TDO pins (pins 38, 39, 43, and 42 respectively in TQFP-100). TRST is not included in this package variant; the TAP controller resets automatically at power-up and via TMS/TCK sequences.
