Renesas 7006L15PFI

Overview

7006L15PFI from IDT is a high-speed 16K × 8 dual-port static RAM with true independent left/right port access, 15 ns max read cycle time (commercial grade), 2V data retention in battery backup mode, and integrated semaphore/arbiter logic for inter-port synchronization. It enables error-free 16-bit-or-wider memory expansion in real-time industrial controllers.

For engineers reviewing the 7006L15PFI datasheet, 7006L15PFI pinout, 7006L15PFI application, or 7006L15PFI equivalent, key selection criteria include simultaneous dual-port read capability, BUSY/INT flag timing at 15 ns, M/S master/slave arbitration support, and industrial temperature operation (–40°C to +85°C) in TQFP package.

Technical Context

The 7006L15PFI implements fully asynchronous dual-port architecture with separate address, control, and I/O buses per port. Its on-chip arbitration logic resolves contention via BUSY flag assertion and supports semaphore signaling using A0–A2 addressing of eight shared flags.

It operates on a single 5V ±10% supply, delivers 700 mW typical active power and 1 mW standby power, and guarantees 2V data retention-enabling nonvolatile operation during main power loss in embedded systems requiring deterministic memory access.

FAQ

What is the maximum operating temperature range for the 7006L15PFI?

The 7006L15PFI is rated for industrial temperature operation from –40°C to +85°C. This specification is validated across all electrical parameters including access time, power consumption, and BUSY arbitration timing. The device uses ceramic-enhanced packaging and process characterization to ensure reliability under thermal cycling conditions typical in motor drives and outdoor control cabinets.

Does the 7006L15PFI support battery backup operation?

Yes, the 7006L15PFI supports battery backup operation with guaranteed 2V data retention (VDR = 2.0 V min). In data retention mode, ICCDR is specified at ≤4000 µA (military/industrial) and ≤1500 µA (commercial), enabling multi-day retention from a small coin-cell battery. The 7006L15PFI enters retention mode automatically when VCC drops below 2.0 V while CE remains asserted.

How does the M/S pin affect BUSY signal behavior on the 7006L15PFI?

When M/S = HIGH, the 7006L15PFI operates as a master: BUSYL and BUSYR become push-pull outputs that assert during port contention. When M/S = LOW, it operates as a slave: BUSYL and BUSYR become inputs, allowing external BUSY signals from a master device to gate write operations. This configuration enables hierarchical arbitration in multi-device memory systems without external logic.

What is the function of the SEM pins on the 7006L15PFI?

The SEML and SEMR pins on the 7006L15PFI enable access to the internal eight-bit semaphore register instead of the main RAM array. When SEM = LOW and CE = HIGH, address bits A0–A2 select one of eight semaphore flags, and I/O0–I/O7 read/write the flag state. This provides hardware-accelerated mutual exclusion for critical sections across dual-processor systems.

Can the 7006L15PFI be used in a 16-bit data bus configuration?

Yes, the 7006L15PFI supports 16-bit-or-wider data bus expansion using its MASTER/SLAVE cascading capability. Two devices are connected with M/S = HIGH (master) and M/S = LOW (slave); the master's BUSY output connects to the slave's BUSY input. This configuration maintains full-speed operation without external arbitration logic and preserves the 15 ns access timing across the combined 16-bit interface.
