Renesas 7005L15PF8

Overview

7005L15PF8 from IDT is a high-speed 8K × 8 dual-port static RAM with true independent left/right ports, 15 ns maximum read cycle time (commercial grade), 5 V ±10% single supply, and integrated hardware semaphore/arbitration logic. It enables simultaneous asynchronous access to the same memory location and supports master/slave cascading for 16-bit+ bus expansion in real-time inter-processor communication systems.

For engineers reviewing the 7005L15PF8 datasheet, 7005L15PF8 pinout, 7005L15PF8 application, or 7005L15PF8 equivalent, this page delivers verified timing specs, validated dual-port arbitration behavior, confirmed TQFP-64 package mapping, and precise BUSY/INT/SEM functional boundaries - all critical for deterministic multi-core shared-memory designs.

Technical Context

The 7005L15PF8 implements fully asynchronous dual-port operation with separate address, data, and control buses per port (A0L–A12L/I/O0L–I/O7L vs. A0R–A12R/I/O0R–I/O7R), enabling concurrent reads/writes without external logic. Its on-chip arbitration uses push-pull BUSY flags and M/S-selectable master/slave mode to resolve port contention at the hardware level.

It integrates eight dedicated semaphore registers (addressed by A0–A2) with atomic read/write control via SEM and OE pins, and supports interrupt flag generation (INTL/INTR) triggered by specific address writes (e.g., 1FFF_H sets INTR). Data retention operates down to 2 V with ≤100 µA ICCDR (typical).

Key Specifications

Pinout & Package

7005L15PF8 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 pins require decoupling; all GND pins must be connected to ground plane.

FAQ

What is the maximum operating temperature range for the 7005L15PF8?

The 7005L15PF8 is rated for commercial temperature operation from 0°C to +70°C. It is not qualified for industrial (−40°C to +85°C) or military ranges - those variants use different suffixes (e.g., 7005L15PI or 7005L15PM) and undergo additional screening.

Does the 7005L15PF8 support true simultaneous read from both ports to the same memory address?

Yes, the 7005L15PF8 uses true dual-port SRAM cells that permit concurrent reads from identical addresses on the left and right ports without contention or timing penalty - a core architectural feature confirmed in the functional block diagram and truth tables.

How does the M/S pin affect BUSY signal behavior on the 7005L15PF8?

When M/S = HIGH, the 7005L15PF8 operates as a master: BUSYL and BUSYR are push-pull outputs asserting during port contention. When M/S = LOW, it operates as a slave: BUSYL and BUSYR become inputs that inhibit writes when driven LOW by a master device.

What is the minimum supply voltage required to retain data in the 7005L15PF8?

The 7005L15PF8 guarantees data retention down to 2.0 V (VDR = 2.0 V), with typical retention current ICCDR of 100 µA at 2 V - enabling reliable operation during brownout or battery-backup scenarios.

Can the 7005L15PF8 be used in a 16-bit data bus configuration?

Yes, the 7005L15PF8 supports 16-bit expansion via master/slave cascading: one device configured as master (M/S = HIGH) and another as slave (M/S = LOW) enables full-speed, error-free 16-bit word access without external arbitration logic.
