Renesas 70V9369L9PFG

Overview

70V9369L9PFG from Renesas (formerly IDT) is a high-speed, 3.3V, 16K × 18-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 supports pipelined (15 ns cycle, 67 MHz) and flow-through output modes, features separate upper/lower byte controls, and operates across commercial temperature range (0°C to +70°C) in a 100-pin TQFP package - used in high-bandwidth inter-processor communication and FPGA co-processor buffering.

For engineers reviewing the 70V9369L9PFG datasheet, 70V9369L9PFG pinout, 70V9369L9PFG application, or 70V9369L9PFG equivalent, key selection considerations include pipelined vs. flow-through timing mode selection, dual chip enable depth expansion capability, LVTTL-compatible 3.3V operation, counter-enabled burst addressing, and low-power standby (1.5 mW typ.) with self-timed write architecture.

Technical Context

The 70V9369L9PFG implements fully synchronous dual-port operation with registered address, data, and control inputs on both ports - all clocked on the rising edge of CLKL/CLKR. Its internal architecture includes independent address strobe (ADSL/ADSR) and counter enable/reset logic, allowing external address loading or automatic sequential addressing without bus arbitration overhead.

It supports two distinct output timing architectures: flow-through mode (tCD1 ≤ 20 ns max) for minimal latency reads, and pipelined mode (tCD2 ≤ 9 ns max, tCYC2 = 15 ns) optimized for sustained burst throughput. Chip enables CE0/CE1 are double-buffered in pipelined mode, requiring two cycles to re-enable outputs after power-down - a critical timing constraint for real-time deterministic systems.

Key Specifications

Pinout & Package

70V9369L9PFG is housed in a 100-pin Thin Quad Flatpack (TQFP, package code PNG100) with exposed pad thermal design. Pin numbering follows standard top-view orientation with pin 1 at top-left corner (marked by dot or beveled corner). All VDD (pins 34, 50, 66, 82) must be decoupled locally; all VSS (pins 35, 51, 67, 83, 100) require low-impedance ground connection.

FAQ

What is the maximum operating frequency of the 70V9369L9PFG in pipelined mode?

The 70V9369L9PFG achieves a minimum clock cycle time of 15 ns in pipelined output mode, corresponding to a maximum operating frequency of 67 MHz. This is validated across the commercial temperature range (0°C to +70°C) at VDD = 3.3 V ±0.3 V. The device maintains this performance with full setup/hold timing margins on all synchronous inputs including address, data, and control signals.

Does the 70V9369L9PFG support true simultaneous read/write to the same memory location?

Yes, the 70V9369L9PFG uses true dual-ported SRAM cells that allow independent, concurrent read and write operations to identical addresses on the left and right ports. This architecture eliminates bus contention and arbitration logic, enabling deterministic real-time data exchange - a core feature confirmed in the functional block diagram and truth tables of the official datasheet.

How does the address counter function in the 70V9369L9PFG, and what is its bit width?

The 70V9369L9PFG integrates a 14-bit address counter per port, controlled by CNTENL/CNTENR and CNTRSTL/CNTRSTR inputs. When CNTEN = VIL, the counter advances on each rising clock edge; CNTRST = VIL resets it to address 0x0000. This enables automatic sequential addressing for burst transfers - eliminating need for external counters in applications like video line buffering or packet streaming.

What power-saving features does the 70V9369L9PFG offer, and how low is standby current?

The 70V9369L9PFG provides multiple power-saving states: full standby (ISB3 = 0.4 mA typ.) when both ports are disabled with CMOS-level inputs, and port-specific standby (ISB2 = 100 mA typ.) when one port is active. Its active power is 500 mW typ., and standby drops to 1.5 mW typ. - achieved via dual chip enables (CE0/CE1) that gate internal circuitry without requiring external regulators or sequencing.

Is the 70V9369L9PFG pin-compatible with other speed grades in the same family, such as 70V9369L6PFG or 70V9369L12PFG?

Yes, all speed grades in the 70V9369LxPFG series - including 70V9369L6PFG (6 ns), 70V9369L9PFG (9 ns), and 70V9369L12PFG (12 ns) - share identical 100-pin TQFP (PNG100) packaging and pinout. They differ only in AC timing parameters and DC power consumption; no PCB layout change is needed when upgrading or downgrading speed grade within the same temperature grade (commercial).
