Renesas 7006L15PFI8

Overview

7006L15PFI8 from IDT is a high-speed 16K × 8 (128 Kbit) true dual-port static RAM with independent left/right ports, 15 ns max read cycle time, industrial temperature range (–40°C to +85°C), and 1 mW typical standby power. It enables simultaneous asynchronous access to the same memory location and supports master/slave arbitration for 16-bit-or-wider bus expansion in real-time embedded control systems.

For engineers reviewing the 7006L15PFI8 datasheet, 7006L15PFI8 pinout, 7006L15PFI8 application, or 7006L15PFI8 equivalent, key selection criteria include BUSY/INT flag timing, semaphore arbitration latency, dual-port contention resolution behavior, and compatibility with 5 V ±10% TTL-level control interfaces in deterministic multi-processor memory sharing architectures.

Technical Context

The 7006L15PFI8 implements fully asynchronous dual-port operation with separate address, data, and control buses per port. Its on-chip arbitration logic resolves port contention via hardware BUSY flag assertion (M/S = H) or BUSY input (M/S = L), and supports eight semaphore flags addressed by A0–A2 for inter-processor synchronization.

It features full on-chip semaphore signaling, interrupt flag generation (INTL/INTR), and battery-backed data retention at 2 V. The device uses CMOS process technology and operates from a single 5 V ±10% supply, with all I/Os TTL-compatible and ESD-rated >2001 V.

Key Specifications

Pinout & Package

7006L15PFI8 is packaged in a 64-pin thin quad flatpack (TQFP), body size 14 mm × 14 mm × 1.4 mm, with 0.5 mm lead pitch and exposed thermal pad. All VCC and GND pins require proper decoupling per layout guidelines.

FAQ

What is the maximum operating temperature range for the 7006L15PFI8?

The 7006L15PFI8 is rated for industrial temperature operation from –40°C to +85°C. This specification is confirmed in the Absolute Maximum Ratings table and DC Electrical Characteristics section of the official IDT datasheet, and applies across all speed grades including the 15 ns variant. Operation outside this range may result in parametric failure or reduced reliability.

Does the 7006L15PFI8 support battery backup operation?

Yes, the 7006L15PFI8 supports battery backup operation with guaranteed data retention at VCC = 2.0 V minimum. This is explicitly specified in the Data Retention Characteristics table (tCDR and VDR parameters) and confirmed in the "Battery backup operation-2V data retention" feature list. The L-version (low-power) variant is optimized for this mode, drawing only 100–4000 µA during retention depending on grade.

How does the M/S pin affect BUSY signal behavior on the 7006L15PFI8?

When M/S = H (high), the 7006L15PFI8 operates as Master: BUSYL and BUSYR are push-pull outputs that assert during port contention. When M/S = L (low), it operates as Slave: BUSYL and BUSYR become inputs, allowing external BUSY signals from a Master device to gate writes. This is defined in the Pin Names table and Truth Table I, and enables hierarchical arbitration in multi-device configurations.

Can the 7006L15PFI8 be used in a 16-bit data bus configuration?

Yes, the 7006L15PFI8 supports 16-bit-or-wider bus expansion using the Master/Slave select (M/S) feature. Two devices can be cascaded - one as Master (M/S = H), one as Slave (M/S = L) - with BUSY chaining to maintain full-speed error-free operation without additional discrete logic, as described in the Functional Description and Features sections.

What is the meaning of the 'PFI8' suffix in 7006L15PFI8?

The 'PFI8' suffix denotes the package and temperature grade: 'P' = TQFP (thin quad flatpack), 'F' = industrial temperature range (–40°C to +85°C), 'I' = lead-free (RoHS-compliant), and '8' = tape-and-reel packaging. This coding aligns with IDT's standard ordering nomenclature documented in the datasheet's Ordering Information section.
