Renesas 7006L20PFGI

Overview

7006L20PFGI from IDT is a high-speed 16K × 8 (128 Kbit) true dual-port static RAM with independent left/right ports, 20 ns maximum access time (industrial grade), 1 µW typical standby power, and TTL-compatible 5 V ±10% operation. It supports simultaneous reads of the same memory location and is used in real-time inter-processor communication, video frame buffers, and military-grade avionics data exchange systems.

For engineers reviewing the 7006L20PFGI datasheet, 7006L20PFGI pinout, 7006L20PFGI application, or 7006L20PFGI equivalent, key selection criteria include industrial temperature range (–40°C to +85°C), BUSY/INT/SEM arbitration logic, 64-pin TQFP package compatibility, and battery backup data retention at 2 V.

Technical Context

The 7006L20PFGI implements fully asynchronous dual-port architecture with on-chip port arbitration, semaphore signaling, and interrupt flag generation. Its left and right ports feature separate address (A0L–A13L / A0R–A13R), data (I/O0L–I/O7L / I/O0R–I/O7R), and control (CEL/CER, R/WL/R/WR, OEL/OER) lines.

It supports MASTER/SLAVE cascading via M/S pin for 16-bit+ bus expansion, with BUSYL/BUSYR operating as output (MASTER) or input (SLAVE). Semaphore flags are accessed via A0–A2 and I/O0–I/O7, enabling hardware-coordinated resource sharing between ports.

Key Specifications

Pinout & Package

7006L20PFGI is housed in a 64-pin thin quad flatpack (TQFP), designated PNG64, with 0.5 mm pitch, 14 mm × 14 mm body size, and 1.4 mm height. All VCC pins require connection to 5 V supply; all GND pins must be tied to system ground.

FAQ

What is the operating temperature range for the 7006L20PFGI?

The 7006L20PFGI is rated for industrial temperature operation from –40°C to +85°C. This range is validated per manufacturer specifications and supports deployment in harsh environments such as factory automation controllers, transportation electronics, and outdoor communications infrastructure where ambient thermal stability cannot be guaranteed.

Does the 7006L20PFGI support battery backup data retention?

Yes, the 7006L20PFGI supports battery backup data retention at 2 V VCC with typical current draw of 100 µA. This capability is explicitly specified in the "Data Retention Characteristics" section of the official datasheet and enables memory state preservation during main power interruption-critical for avionics and medical device applications.

How does the M/S pin configure MASTER vs. SLAVE operation in the 7006L20PFGI?

When M/S = HIGH, the 7006L20PFGI operates as MASTER: BUSYL and BUSYR function as push-pull outputs indicating port contention. When M/S = LOW, it operates as SLAVE: BUSYL and BUSYR become inputs, allowing external BUSY signals from a MASTER device to gate writes-enabling scalable multi-device memory expansion without additional logic.

What is the significance of the "L" suffix in 7006L20PFGI?

The "L" denotes the low-power variant of the IDT7006 family. Compared to the "S" (standard) version, the 7006L20PFGI reduces active power to 700 mW typ and standby power to 1 mW typ, while enabling 2 V data retention. These characteristics are confirmed in the "DC Electrical Characteristics" tables and define its suitability for energy-constrained and battery-backed systems.

Can the 7006L20PFGI perform simultaneous reads from both ports to the same memory address?

Yes, the 7006L20PFGI supports true simultaneous reads of the same memory location from both ports-this is a core architectural feature confirmed in the "Features" section and functional block diagram. No arbitration or BUSY assertion occurs during concurrent reads, ensuring deterministic latency and eliminating read-contention delays in dual-CPU architectures.
