Product details

Overview

IDT7006L15JG from Integrated Device Technology (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 single-supply operation, and integrated semaphore/arbiration logic - used in real-time inter-processor communication, video frame buffers, and military-grade avionics data exchange systems.

For engineers reviewing the IDT7006L15JG datasheet, IDT7006L15JG pinout, IDT7006L15JG application, or IDT7006L15JG equivalent, key selection criteria include simultaneous dual-port read capability, BUSY/INT flag timing at 15 ns, battery-backed 2 V data retention, TTL-compatible I/O, and 64-pin TQFP packaging for space-constrained embedded designs.

Technical Context

The IDT7006L15JG implements fully asynchronous dual-port architecture with separate address, control, and bidirectional I/O buses per port. Its on-chip arbitration logic resolves contention via BUSY flag assertion and supports MASTER/SLAVE cascading using the M/S pin to expand data width beyond 8 bits without external logic.

It features dedicated semaphore registers (addressed by A0–A2) accessible via SEM = VIL, and interrupt flags (INTL/INTR) that latch on write to specific addresses. The device operates across commercial temperature range (0°C to +70°C) and retains data at 2 V with ≤100 µA typical ICCDR.

INTL / INTR	Interrupt Flag (Left/Right)	Open-drain or push-pull (configurable); signals semaphore/interrupt event to host processor
M/S	Master/Slave Select	HIGH = BUSY output (MASTER), LOW = BUSY input (SLAVE) for cascaded configurations
VCC / GND	Power & Ground	Four VCC and six GND pins ensure stable supply distribution and low-noise operation

FAQ

What is the maximum operating speed of the IDT7006L15JG?

The IDT7006L15JG has a maximum read cycle time (tRC) of 15 ns, supporting up to 66.7 MHz sustained memory access per port. This speed is guaranteed across the commercial temperature range (0°C to +70°C) with VCC = 5.0 V ±10%. Write cycle time (tWC) is also rated at 15 ns, ensuring symmetrical high-speed performance for both read and write operations on either port.

Does the IDT7006L15JG support battery backup operation?

Yes, the IDT7006L15JG supports battery backup operation with guaranteed data retention at VCC = 2.0 V and typical ICCDR ≤100 µA. This allows the device to maintain valid memory contents during main power failure - a critical feature for avionics, medical, and industrial control systems where data integrity must persist through brown-outs or emergency shutdowns.

How does the BUSY arbitration mechanism work on the IDT7006L15JG?

The IDT7006L15JG uses hardware-based BUSY arbitration: when both ports attempt simultaneous access to the same memory location, the MASTER port (M/S = VIH) asserts BUSY on the SLAVE port (M/S = VIL) to block its R/W operation until contention resolves. Timing parameters like tBDD (BUSY disable to valid data) are specified at 18 ns max for the 15 ns speed grade, ensuring deterministic resolution without software intervention.

Can the IDT7006L15JG be used in MASTER/SLAVE cascaded configurations?

Yes, the IDT7006L15JG supports MASTER/SLAVE cascading via the M/S pin: set M/S = VIH for MASTER (BUSY output) and M/S = VIL for SLAVE (BUSY input). This enables seamless expansion to 16-bit or wider data paths without external glue logic - the on-chip arbitration logic automatically coordinates access across multiple devices in daisy-chained topologies.

What package type is used for the IDT7006L15JG?

The IDT7006L15JG is packaged in a 64-pin Thin Quad Flatpack (TQFP) with 0.5 mm lead pitch, 14 mm × 14 mm body size, and 1.4 mm height. This RoHS-compliant package provides optimal thermal performance and board-space efficiency for high-density embedded designs while maintaining compatibility with standard surface-mount assembly processes.
