Renesas 7006L17G

Overview

7006L17G from IDT is a high-speed 16K × 8 dual-port static RAM with true independent left/right port access, 17 ns maximum read cycle time (commercial grade), 700 mW typical active power, and 1 µA typical standby current. It supports simultaneous reads of the same memory location and is used in real-time interprocessor communication systems requiring deterministic arbitration and semaphore signaling.

For engineers reviewing the 7006L17G datasheet, 7006L17G pinout, 7006L17G application, or 7006L17G equivalent, this page delivers verified electrical specs, validated 68-pin PGA pin mapping, confirmed industrial-temperature capability (–40°C to +85°C), and two production-validated alternative parts for memory subsystem design and BOM continuity planning.

Technical Context

The 7006L17G implements fully asynchronous dual-port operation with separate address, control, and I/O buses per port, enabling concurrent read/write operations without external logic. Its on-chip arbitration logic resolves contention via BUSY flag assertion and supports master/slave cascading using the M/S pin.

It integrates full hardware semaphore signaling across ports-eight flags accessible via A0–A2-and provides interrupt generation (INTL/INTR) with programmable set/reset timing. The device operates from a single 5 V ±10% TTL-compatible supply and retains data down to 2 V for battery backup applications.

Key Specifications

Pinout & Package

7006L17G is packaged in a 68-pin ceramic Pin Grid Array (PGA), PLG68 package, with 4 VCC pins, 4 GND pins, and fully segregated left/right port signals including dedicated BUSY, SEM, and INT lines.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual-port SRAM applications.

Compared with CY7C024AV-15AXC and IDT70V25L15PF, the 7006L17G uniquely combines 5 V TTL compatibility, 2 V battery retention, master/slave arbitration, and industrial temperature range in a 68-pin PGA-making it irreplaceable in legacy avionics and ruggedized control systems where voltage and footprint constraints are fixed.

Availability

7006L17G is available at Aetrix Electronics and suitable for real-time interprocessor communication, digital signal processing buffering, industrial PLC memory coherency, and avionics data acquisition requiring stable component supply across extended lifecycle programs.

Supply support for 7006L17G includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

FAQ

What is the maximum operating temperature range for the 7006L17G?

The 7006L17G is rated for industrial temperature operation from –40°C to +85°C. This specification is explicitly confirmed in the datasheet's "Maximum Operating Temperature and Supply Voltage" table and applies to all speed grades including the 17 ns variant. No derating is required within this range, and the device maintains full parameter compliance per the DC and AC electrical characteristics tables.

Does the 7006L17G support battery backup operation, and what voltage is required?

Yes, the 7006L17G supports battery backup operation with guaranteed data retention down to 2.0 V (VDR = 2.0 V min). This is a defining feature of the "L" (low-power) version, confirmed in the "Data Retention Characteristics" section. At VCC = 2 V, typical data retention current is 100 µA, enabling multi-year backup from standard lithium coin cells without external regulators.

How does the M/S pin affect BUSY signal behavior on the 7006L17G?

When M/S = H (high), the 7006L17G operates as a master: BUSYL and BUSYR become output signals that assert during port contention. When M/S = L (low), it operates as a slave: BUSYL and BUSYR become inputs monitored by the device to gate write operations. This dual-role configuration is essential for cascading multiple 7006L17G devices into wider memory systems without external arbitration logic.

Can the 7006L17G perform simultaneous reads from both ports to the same memory address?

Yes, the 7006L17G supports true simultaneous reads to the same memory location from both ports-this is a core feature explicitly stated in the "Features" section. Unlike single-port or pseudo-dual-port RAMs, its memory cell architecture permits concurrent left-port and right-port read access without conflict, delay, or data corruption, enabling lock-free data sharing in symmetric multiprocessing environments.

What package type is used for the 7006L17G, and are pin-compatible alternatives available in other packages?

The 7006L17G uses a 68-pin ceramic Pin Grid Array (PGA), designated PLG68. While the same 7006L die is offered in 68-pin flatpack (FP68), 64-pin TQFP (PNG64), and PLCC variants, these are distinct orderable parts (e.g., 7006L17G vs. 7006L17P) with non-interchangeable pinouts. The PGA variant has unique mechanical and thermal characteristics-especially critical for high-reliability mil-aero applications-and is not pin-compatible with the TQFP or PLCC versions.
