Renesas 7006L25PF

Overview

IDT7006L25PF from Integrated Device Technology (IDT) is a high-speed 16K × 8 dual-port static RAM with true independent left/right port access, 25 ns maximum read cycle time, TTL-compatible 5V ±10% operation, and industrial temperature range (–40°C to +85°C). It enables simultaneous reads of the same memory location and supports master/slave cascading for 16-bit+ bus expansion in real-time embedded control systems.

For engineers reviewing the IDT7006L25PF datasheet, IDT7006L25PF pinout, IDT7006L25PF application, or IDT7006L25PF equivalent, key selection criteria include BUSY/INT flag timing, semaphore arbitration latency, standby current (1 µA typ.), data retention at 2V, and compatibility with 64-pin TQFP layout constraints.

Technical Context

The IDT7006L25PF 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 (output when M/S = H, input when M/S = L) and supports semaphore signaling using A0–A2 to select among eight flags.

It features hardware-supported interrupt generation (INTL/INTR), automatic power-down via CE control, and battery backup capability with 2V data retention. The device uses CMOS process technology and meets MIL-PRF-38535 QML Class B requirements for military-grade reliability when ordered in appropriate grade variants.

FAQ

What is the guaranteed maximum access time for IDT7006L25PF under industrial temperature conditions?

The IDT7006L25PF guarantees a maximum read cycle time (tRC) of 25 ns across the full industrial temperature range (–40°C to +85°C) with VCC = 5.0 V ±10%. This specification is production-tested and applies to both ports independently, enabling deterministic timing in hard real-time applications without derating.

Does IDT7006L25PF support battery backup operation, and what is the minimum retention voltage?

Yes, the IDT7006L25PF supports battery backup operation with guaranteed data retention down to 2.0 V (VDR), as specified in Table 9 of the datasheet. This allows seamless transition to backup power during main supply interruption, maintaining memory state without external circuitry.

How does the M/S pin affect BUSY flag behavior in IDT7006L25PF?

When M/S = H, BUSYL/BUSYR operate as push-pull outputs indicating port contention; when M/S = L, they become inputs accepting BUSY signals from a master device. This configuration enables hierarchical arbitration in multi-device systems, and the IDT7006L25PF must be assigned master or slave role at power-up.

Can IDT7006L25PF perform simultaneous reads from both ports to the same memory address?

Yes, the IDT7006L25PF supports true simultaneous reads to the same memory location from both ports without conflict or performance penalty. This capability is enabled by its dual-port memory cell architecture and is explicitly confirmed in the Features section of the datasheet.

What package type and pin count does IDT7006L25PF use, and are thermal pads supported?

IDT7006L25PF uses a 64-pin Thin Quad Flatpack (TQFP) with 0.5 mm pitch and dimensions 14 mm × 14 mm × 1.4 mm. The package does not include an exposed thermal pad; thermal dissipation relies on PCB copper area connected to multiple VCC/GND pins as specified in the pin configuration diagram.
