Renesas 70V9369L9PFG8

Overview

70V9369L9PFG8 from Renesas (formerly IDT) is a high-speed, 3.3V, 16K × 18-bit synchronous dual-port static RAM with pipelined and flow-through output modes, 9 ns clock-to-data access in pipelined mode, 15 ns cycle time at 67 MHz, and true dual-ported memory cells enabling simultaneous read/write access to the same address from independent left and right ports - used in high-bandwidth inter-processor communication and real-time DSP buffering.

For engineers reviewing the 70V9369L9PFG8 datasheet, 70V9369L9PFG8 pinout, 70V9369L9PFG8 application, or 70V9369L9PFG8 equivalent, key selection considerations include synchronous dual-port timing compliance, 100-pin TQFP package compatibility, LVTTL-level 3.3V operation, pipelined vs. flow-through mode configuration via FT/PIPE pins, and industrial-grade power-down behavior under dual chip enable control.

Technical Context

The 70V9369L9PFG8 implements fully synchronous operation on both ports with registered address, data, and control inputs - all latched on the rising edge of CLKL/CLKR - delivering 4 ns setup and 1 ns hold times. Its self-timed write architecture enables fast cycle time without external timing constraints.

It supports two distinct output architectures: pipelined (FT/PIPE = VIH), yielding 9 ns clock-to-data valid (tCD2) and 15 ns cycle time; and flow-through (FT/PIPE = VIL), with 20 ns tCD1 and 25 ns tCYC1. Address counter logic allows automatic sequential addressing with CNTEN/CNTRST control, independent of chip enable state.

Key Specifications

Pinout & Package

70V9369L9PFG8 is housed in a 100-pin TQFP (PNG100) package with exposed thermal pad; all VDD pins require connection to 3.3 V supply, and all VSS pins must be grounded. Pin 1 is located at top-left corner (notch-marked side).

FAQ

What is the maximum operating frequency of the 70V9369L9PFG8 in pipelined mode?

The 70V9369L9PFG8 achieves a 15 ns clock cycle time (tCYC2) in pipelined output mode, supporting a maximum operating frequency of 67 MHz. This is confirmed in AC Electrical Characteristics Table 11 for the 70V9369L9 speed grade under commercial temperature conditions (0°C to +70°C). The device sustains this rate with full 18-bit data throughput per port.

Does the 70V9369L9PFG8 support independent byte-write capability?

Yes, the 70V9369L9PFG8 supports independent upper- and lower-byte writes via UBL/UBR and LBL/LBR control signals. Each port can selectively enable or disable its upper 9 bits (I/O9–I/O17) or lower 9 bits (I/O0–I/O8), allowing 9-bit granularity writes without affecting the complementary byte - essential for mixed-width bus interfacing and partial register updates.

How does the address counter function on the 70V9369L9PFG8?

The 70V9369L9PFG8 integrates an internal address counter per port, controlled by CNTENL/CNTENR and CNTRSTL/CNTRSTR. When CNTEN = VIL on the rising clock edge, the counter advances automatically; CNTRST = VIL resets it to address 0. Counter operation is independent of chip enable state and functions in both pipelined and flow-through modes, enabling efficient FIFO and buffer pointer handling.

What power-saving modes does the 70V9369L9PFG8 offer?

The 70V9369L9PFG8 provides multiple power-saving states: full standby (ISB3 = 0.4 mA typ) when both ports are disabled with CMOS-level inputs; single-port standby (ISB4 = 90 mA typ); and dynamic power reduction via dual CE control. Entering standby requires CE0 = VIH and CE1 = VIH per port, and exit latency depends on FT/PIPE setting - pipelined mode requires two cycles to re-enable outputs.

Is the 70V9369L9PFG8 pin-compatible with other speed grades in the same family?

Yes, all 70V9369Lx variants - including 70V9369L6, 70V9369L7, 70V9369L9, and 70V9369L12 - share identical 100-pin TQFP (PNG100) packaging and pinout. Differences are limited to AC timing parameters (e.g., tCD2, tCYC2) and DC current consumption; no PCB redesign is needed when upgrading or downgrading speed grades within the same temperature grade.
