Renesas 7006L15PF

Overview

7006L15PF 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 (commercial grade), 5 V ±10% single supply, and integrated semaphore/arbiter logic for inter-port synchronization. It enables simultaneous asynchronous access to the same memory location and supports master/slave cascading for 16-bit+ data bus expansion in real-time embedded control systems.

For engineers reviewing the 7006L15PF datasheet, 7006L15PF pinout, 7006L15PF application, or 7006L15PF equivalent, this page delivers verified electrical specs, package mapping to 64-pin TQFP, functional role in arbitration-driven dual-processor memory sharing, and validated alternatives for industrial-grade dual-port SRAM replacement.

Technical Context

The 7006L15PF implements fully asynchronous dual-port architecture with separate address, data, and control buses per port (A0L–A13L/I/O0L–I/O7L/R/WL/CEL/OEL on left; A0R–A13R/I/O0R–I/O7R/R/WR/CER/OER on right), enabling concurrent reads/writes without external logic. Its on-chip arbitration logic resolves contention via BUSY flag generation (M/S = H for master output, M/S = L for slave input) and priority setup time (tAPS = 5 ns).

It integrates full hardware semaphore signaling (SEML/SEMR), interrupt flags (INTL/INTR), and automatic power-down via CE-controlled standby modes - delivering 1 mW typical standby power (L-version) and 2 V battery-backed data retention. All timing parameters (tRC, tAA, tACE, tAOE) are specified at TA = 0°C to +70°C and VCC = 5.0 V ±10%.

Compared with CY7C136-15VC and AS7C316098B-15TIN, the 7006L15PF uniquely integrates BUSY arbitration, semaphore registers, and interrupt flags in a 5 V, 64-pin TQFP package - making it the only drop-in solution for legacy dual-processor systems requiring deterministic, hardware-enforced memory coherency without redesign.

FAQ

What is the maximum operating frequency supported by the 7006L15PF?

The 7006L15PF supports a maximum read cycle time (tRC) of 15 ns, corresponding to an effective maximum operating frequency of 66.7 MHz. This is guaranteed under commercial temperature range (0°C to +70°C) and VCC = 5.0 V ±10%. The device achieves this speed with fully asynchronous operation - no clock required - and maintains timing integrity across both ports simultaneously.

Does the 7006L15PF support battery backup operation, and what voltage is required?

Yes, the 7006L15PF supports battery backup operation with data retention down to 2.0 V (VDR = 2.0 V min). In data retention mode (CE > VHC, VIN > VHC or < VLC), it draws ≤ 4000 µA (military/industrial grade) or ≤ 1500 µA (commercial grade), enabling reliable hold functionality during main power failure. This feature is intrinsic to the "L" (low-power) variant and is not available in the "S" version.

How does the M/S pin configure master versus slave behavior in the 7006L15PF?

When M/S = H (high), the 7006L15PF operates as a master: BUSYL and BUSYR become push-pull outputs that assert during port contention. When M/S = L (low), it operates as a slave: BUSYL and BUSYR become inputs, allowing external BUSY signals from a master device to gate local write operations. This enables daisy-chained configurations for wider data buses - e.g., two 7006L15PF devices cascaded as master/slave form a 16-bit-wide dual-port memory without external logic.

Can the 7006L15PF perform simultaneous reads from both ports to the same memory address?

Yes, the 7006L15PF uses true dual-port memory cells that permit simultaneous reads from both the left and right ports to the exact same memory location without contention, latency penalty, or data corruption. This capability is fundamental to its architecture and requires no arbitration or BUSY assertion - unlike simultaneous read/write or write/write operations, which trigger hardware arbitration via the BUSY flag.

What package type and pin count does the 7006L15PF use, and are thermal pads included?

The 7006L15PF uses a 64-pin Thin Quad Flatpack (TQFP) package (PNG64), measuring 14 mm × 14 mm × 1.4 mm. It has no exposed thermal pad - thermal dissipation relies on standard PCB copper pour connected to multiple VCC and GND pins. The pinout is fully documented in the datasheet (drawing 2739 drw 03), with dedicated power/ground distribution to minimize noise coupling between ports.
