Renesas 7006S15PF

Overview

7006S15PF from IDT is a high-speed 16K × 8 true dual-port static RAM with 15 ns maximum access time, TTL-compatible 5V ±10% supply, and industrial temperature range (–40°C to +85°C). It supports simultaneous independent read/write operations on left and right ports, features on-chip semaphore logic and BUSY arbitration, and is used in real-time embedded systems requiring deterministic inter-processor communication.

For engineers reviewing the 7006S15PF datasheet, 7006S15PF pinout, 7006S15PF application, or 7006S15PF equivalent, this page delivers verified specifications, package mapping, functional role in master/slave memory expansion, and validated alternatives for dual-port SRAM selection in avionics, industrial PLCs, and telecom line cards.

Technical Context

The 7006S15PF implements fully asynchronous dual-port architecture with separate address, data, and control buses per port. Its on-chip arbitration logic resolves contention via BUSY flag assertion-either by chip enable (CE) or address match-and supports both master (BUSY output) and slave (BUSY input) configurations via M/S pin.

It integrates full hardware semaphore signaling across eight flags addressed by A0–A2, enabling inter-port synchronization without external logic. The device operates in battery backup mode at 2V with data retention, and supports TTL-level inputs while delivering CMOS-compatible outputs with 0.4V VOL and 2.4V VOH under 4mA load.

Key Specifications

Pinout & Package

7006S15PF is housed in a 64-pin thin quad flatpack (TQFP) with 0.5 mm pitch, compliant with JEDEC MO-153. All VCC pins require decoupling; all GND pins must be connected to system ground plane for signal integrity.

FAQ

What is the maximum operating temperature range for the 7006S15PF?

The 7006S15PF 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 to all speed grades including the 15 ns variant. Operation outside this range may cause timing violations or data retention failure.

Does the 7006S15PF support battery backup operation?

Yes, the 7006S15PF 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 = 0 ns, VDR = 2.0 V), and applies to the "S" speed grade. The device draws ≤100 µA typical in retention mode, enabling multi-year backup with small coin cells.

How does the M/S pin configure master versus slave operation in the 7006S15PF?

When M/S = HIGH, the 7006S15PF 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, accepting BUSY signals from a master device. This configuration enables scalable multi-device memory expansion without external arbitration logic.

Can the 7006S15PF perform simultaneous reads from both ports to the same memory location?

Yes, the 7006S15PF supports true simultaneous reads from both ports to the same memory address. This capability is explicitly stated in the Features section ("True Dual-Ported memory cells which allow simultaneous reads of the same memory location") and is enabled by its dual-port cell architecture - no BUSY assertion or arbitration delay occurs during concurrent reads.

What package type is used for the 7006S15PF, and are there thermal or layout considerations?

The 7006S15PF uses a 64-pin TQFP (PNG64) package measuring 14 mm × 14 mm × 1.4 mm. Layout requires all four VCC and six GND pins to be individually decoupled with 0.1 µF ceramics near each pin, and a solid ground plane beneath the package. Thermal derating is not required up to +85°C ambient when mounted on 2 oz copper with ≥4 thermal vias under the exposed pad (if present - though PNG64 has no thermal pad).
