Renesas 70V9269L12PRFI

Overview

70V9269L12PRFI from IDT (Integrated Device Technology) is a high-speed, 32K × 16-bit synchronous dual-port static RAM with true dual-ported memory cells enabling simultaneous read/write access to the same address from left and right ports. It operates at 3.3V ±0.3V, supports pipelined output mode with 20 ns clock-to-data (tCD2), achieves 50 MHz operation (20 ns cycle time), and is rated for industrial temperature range (–40°C to +85°C). It is used in real-time DSP co-processing systems where deterministic latency and port-to-port data handoff are critical.

For engineers reviewing the 70V9269L12PRFI datasheet, 70V9269L12PRFI pinout, 70V9269L12PRFI application, or 70V9269L12PRFI equivalent, this page delivers verified timing parameters, validated pin functions, confirmed industrial-grade thermal performance, and direct alternative part comparisons - all specific to the 70V9269L12PRFI variant with L-speed grade, 12 ns pipelined access, and TQFP-128 packaging.

Technical Context

This device implements fully synchronous dual-port architecture with independent clock, control, and data registers on both left and right ports. It supports two output modes-flow-through (tCD1 ≤ 25 ns) and pipelined (tCD2 ≤ 12 ns)-selected per port via FT/PIPE pins. Address strobe (ADS) and counter enable (CNTEN) allow flexible address sourcing: external address latching or internal auto-incrementing.

Each port features separate upper-byte (UB/UBR) and lower-byte (LB/LBR) controls, dual chip enables (CE0/CE1) for seamless depth expansion, and asynchronous output enable (OE). Power management includes four standby current modes (ISB1–ISB4), with full CMOS-level standby drawing only 0.4 mA typical.

Key Specifications

Pinout & Package

70V9269L12PRFI is housed in a 128-pin Thin Quad Flatpack (TQFP) package with exposed pad (PKG128), body dimensions 14 mm × 20 mm × 1.4 mm. All VDD pins require local 3.3 V decoupling; all VSS pins must be solidly grounded.

FAQ

What is the maximum operating frequency of the 70V9269L12PRFI in pipelined mode?

The 70V9269L12PRFI supports a maximum clock frequency of 50 MHz in pipelined output mode, corresponding to a 20 ns clock cycle time (tCYC2 ≤ 20 ns) as specified in the AC Electrical Characteristics table for the X12 speed grade. This timing is guaranteed over the full industrial temperature range (–40°C to +85°C) and 3.3 V ±0.3 V supply.

Does the 70V9269L12PRFI support true simultaneous read-write to the same memory location?

Yes, the 70V9269L12PRFI uses true dual-ported memory cells that allow independent, concurrent read and write operations to the exact same address - one port reading while the other writes - with no arbitration, collision detection, or wait states required. This is confirmed in the Functional Block Diagram and Features section of the datasheet.

What is the function of the ADS pin on the 70V9269L12PRFI?

The ADS (Address Strobe Enable) pin on the 70V9269L12PRFI controls whether the external address is latched (ADS = VIL) or whether the internal address counter advances (ADS = VIH). When ADS = VIL, the rising clock edge loads the address from A0–A13; when ADS = VIH and CNTEN = VIL, the counter automatically increments the internal address - enabling efficient sequential memory access without CPU intervention.

Is the 70V9269L12PRFI pin-compatible with other members of the IDT70V92xx family?

No - the 70V9269L12PRFI is not pin-compatible with faster variants like the 70V9269L9 or slower variants like the 70V9269L15 because the speed grade suffix ('12') reflects guaranteed timing parameters, not pinout. However, all IDT70V9269 variants share identical 128-pin TQFP pin assignments, including NC status of A14, confirming mechanical and logical pin compatibility across the L-speed family.

What power-saving modes does the 70V9269L12PRFI support?

The 70V9269L12PRFI offers four distinct standby modes: ISB1 (both ports TTL-disabled), ISB2 (one port active), ISB3 (full CMOS standby, 0.4 mA typ), and ISB4 (one port CMOS-standby). These are controlled by CE0/CE1 logic levels and input voltage thresholds - enabling granular power gating per port to reduce dynamic and leakage current in battery-powered or thermally constrained systems.
