Renesas 7006L25PFG8

Overview

7006L25PFG8 from IDT is a high-speed 16K × 8 dual-port static RAM with true asynchronous dual-port architecture, 25 ns maximum read cycle time (tRC), 1 mW typical standby power, and industrial temperature range (–40°C to +85°C). It supports simultaneous independent access from left and right ports and is used in real-time inter-processor communication, video frame buffers, and military-grade avionics data exchange.

For engineers reviewing the 7006L25PFG8 datasheet, 7006L25PFG8 pinout, 7006L25PFG8 application, or 7006L25PFG8 equivalent, key selection criteria include BUSY/INT semaphore arbitration timing, 2V battery backup data retention, TTL-compatible 5V ±10% supply, and 64-pin TQFP package compatibility with PCB layout constraints for high-density embedded systems.

Technical Context

The 7006L25PFG8 implements full on-chip hardware semaphore signaling using A0–A2 address lines to control eight shared flags, enabling deterministic resource locking between ports without external logic. Its port arbitration logic resolves contention via M/S pin configuration-Master asserts BUSY output, Slave accepts BUSY input-and supports both CE-controlled and address-match BUSY assertion modes.

It operates fully asynchronously: each port has independent CE, R/W, OE, address, and I/O buses, allowing concurrent reads/writes to identical or different memory locations. The device enters ultra-low-power standby (<1 mW typ.) when both CEL and CER are high, retaining data down to 2V with no refresh required.

Key Specifications

Pinout & Package

7006L25PFG8 is housed in a 64-pin thin quad flatpack (TQFP) with 0.5 mm pitch, body size 14 mm × 14 mm × 1.4 mm. All VCC and GND pins require dedicated decoupling per datasheet layout guidelines.

FAQ

What is the guaranteed maximum access time for the 7006L25PFG8?

The 7006L25PFG8 guarantees a maximum read cycle time (tRC) of 25 ns across its full industrial temperature range (–40°C to +85°C) and supply voltage (4.5 V to 5.5 V). This value is production-tested and applies to both left and right ports independently under standard AC test conditions with 30 pF load and 1.5 V reference levels.

Does the 7006L25PFG8 support battery backup operation?

Yes, the 7006L25PFG8 supports battery backup operation with guaranteed data retention at VCC = 2.0 V minimum. In data retention mode, ICCDR is specified at ≤4000 µA (military/industrial grades), enabling operation from a single lithium cell during main power failure without external circuitry.

How does the M/S pin affect BUSY signal behavior on the 7006L25PFG8?

When M/S = HIGH, the 7006L25PFG8 operates as Master: BUSYL and BUSYR become push-pull outputs that assert during port contention. When M/S = LOW, it operates as Slave: BUSYL and BUSYR become inputs, accepting BUSY signals from a Master device in cascaded configurations - enabling scalable multi-device arbitration.

Can the 7006L25PFG8 perform simultaneous reads from both ports to the same memory address?

Yes, the 7006L25PFG8 uses true dual-port memory cells that allow simultaneous reads from identical addresses on left and right ports without contention, delay, or data corruption. This capability is inherent to its silicon architecture and requires no special timing or control sequence.

What package type is used for the 7006L25PFG8?

7006L25PFG8 uses a 64-pin thin quad flatpack (TQFP) package with 0.5 mm lead pitch and 14 mm × 14 mm body size. The "PFG8" suffix explicitly denotes this PNG64 package variant per IDT's ordering nomenclature, confirmed in the device's pin configuration diagrams and mechanical drawings.
