Renesas 7006L15PFG8

Overview

7006L15PFG8 from IDT is a high-speed 16K × 8 dual-port static RAM with true independent left/right port access, 15 ns maximum read cycle time (commercial grade), 5 V ±10% single-supply operation, and integrated on-chip semaphore and BUSY arbitration logic - deployed in real-time inter-processor communication and video frame buffer systems.

For engineers reviewing the 7006L15PFG8 datasheet, 7006L15PFG8 pinout, 7006L15PFG8 application, or 7006L15PFG8 equivalent, this page delivers verified timing specs (tRC = 15 ns), low-power standby current (1 µA typ.), dual-port arbitration behavior, and TQFP-64 package compatibility for embedded memory coherency designs.

Technical Context

The 7006L15PFG8 implements fully asynchronous dual-port architecture with separate address, control, and I/O buses per port, enabling simultaneous read/write operations to the same memory location without external logic. Its on-chip arbitration resolves contention via BUSY flag assertion and supports MASTER/SLAVE cascading using the M/S pin.

It integrates full hardware semaphore signaling (8 flags, addressed by A0–A2), interrupt generation (INTL/INTR), and power-down control via independent chip enables (CEL/CER). The device operates across commercial temperature range (0°C to +70°C) and retains data at 2 V with typical 100 µA retention current.

Key Specifications

Pinout & Package

7006L15PFG8 is housed in a 64-pin thin quad flatpack (TQFP) package, designated PNG64, with 0.5 mm lead pitch and exposed thermal pad. All VCC pins require decoupling; all GND pins must be connected to system ground.

FAQ

What is the maximum operating frequency supported by the 7006L15PFG8?

The 7006L15PFG8 supports a maximum read cycle time (tRC) of 15 ns, corresponding to an effective maximum operating frequency of 66.7 MHz for continuous read operations. This rating applies under commercial conditions (0°C to +70°C) with VCC = 5.0 V ±10%. Write cycles follow the same timing envelope, and both ports operate asynchronously without synchronization overhead. The 7006L15PFG8 does not specify a clock input - its timing is purely event-driven by CE, R/W, and OE transitions.

Does the 7006L15PFG8 support battery backup operation?

Yes, the 7006L15PFG8 supports battery backup with data retention down to 2.0 V (VDR), drawing only 100 µA typical current in retention mode. This capability is intrinsic to the "L" (low-power) variant and is validated across military, industrial, and commercial temperature ranges. When VCC drops below 2.0 V, the device enters data retention mode automatically - preserving contents without external circuitry. The 7006L15PFG8 requires no special initialization or control signals to activate retention.

How does the BUSY arbitration logic work on the 7006L15PFG8?

The 7006L15PFG8 implements hardware BUSY arbitration through dedicated BUSYL/BUSYR pins and the M/S pin. When configured as Master (M/S = HIGH), BUSY is an output that asserts LOW when address contention occurs on the opposite port. As Slave (M/S = LOW), BUSY is an input that must be monitored before initiating writes. The 7006L15PFG8 guarantees resolution within tBDD (≤30 ns for 15 ns version), preventing simultaneous writes to the same location without software polling or external logic.

Can the 7006L15PFG8 be used in a 16-bit data bus configuration?

Yes, the 7006L15PFG8 supports 16-bit expansion via Master/Slave cascading. Two devices are connected with M/S = HIGH on the master and M/S = LOW on the slave; BUSY signals coordinate access, and the combined configuration provides 16K × 16 organization. No additional glue logic is required - the 7006L15PFG8's built-in arbitration ensures error-free, full-speed operation. This method is explicitly documented in the datasheet as the recommended approach for widening the data path beyond 8 bits.

What are the key differences between the 'S' and 'L' variants of the 7006 series?

The 'S' (standard) and 'L' (low-power) variants differ primarily in active and standby power consumption: the 7006L15PFG8 draws 700 mW typical active power and 1 mW standby, versus 750 mW and 5 mW for the 'S' version. Crucially, only the 'L' variant guarantees 2 V data retention and specifies ISB3 current as low as 0.2 µA - making it suitable for battery-backed applications. Both share identical timing, pinout, and functional features; the 7006L15PFG8 is the low-power, retention-capable derivative.
