Renesas 7006L15JI

Overview

IDT7006L15JI 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 on-chip semaphore and BUSY arbitration logic. It enables simultaneous read/write operations across ports in real-time embedded systems requiring deterministic memory coherency-such as digital signal processors interfacing with host controllers.

For engineers reviewing the IDT7006L15JI datasheet, IDT7006L15JI pinout, IDT7006L15JI application, or IDT7006L15JI equivalent, key selection criteria include its 15 ns access timing, 1 µA typical standby current, industrial temperature range (–40°C to +85°C), TQFP-64 package compatibility, and native support for MASTER/SLAVE cascading in 16-bit+ bus architectures.

Technical Context

The IDT7006L15JI 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 (output when M/S = H, input when M/S = L) and supports semaphore signaling using A0–A2 to select among eight flags.

It features automatic power-down via CE-controlled standby mode, battery backup capability (2 V data retention), and TTL-compatible I/Os. The device uses CMOS process technology to achieve 700 mW typical active power and 1 mW typical standby power at 5 V.

FAQ

What is the operating temperature range specified for the IDT7006L15JI?

The IDT7006L15JI is rated for industrial temperature operation from –40°C to +85°C. This specification is explicitly confirmed in the "Maximum Operating Temperature and Supply Voltage" table and applies to all speed grades within the L-series, including the 15 ns variant. The device meets this range under full 5 V ±10% supply and functional load conditions.

Does the IDT7006L15JI support battery backup operation, and what voltage is required?

Yes, the IDT7006L15JI supports battery backup operation with a minimum retention voltage of 2.0 V, as documented in the "Data Retention Characteristics" section. At V_CC = 2 V, it retains valid data with typical current draw of 100 µA (military/industrial) or 100 µA (commercial), enabling reliable operation during main supply interruption.

How does the M/S pin affect BUSY signal behavior on the IDT7006L15JI?

When M/S = H (high), BUSY is an output flag indicating port contention; when M/S = L (low), BUSY becomes an input used to synchronize slave operation. This dual-role configuration enables hardware daisy-chaining of multiple IDT7006L15JI devices in MASTER/SLAVE topology without external logic, as defined in the Functional Block Diagram and Pin Names table.

Can the IDT7006L15JI be used in a 16-bit data bus configuration?

Yes, the IDT7006L15JI supports 16-bit bus expansion via MASTER/SLAVE cascading. Two devices can be configured-one as MASTER (M/S = H), one as SLAVE (M/S = L)-using BUSY chaining and dedicated semaphore logic to maintain full-speed, error-free operation without additional discrete logic, as described in the device Description section.

What is the typical standby current consumption of the IDT7006L15JI?

The IDT7006L15JI has a typical standby current of 1 µA, measured under full standby conditions (both ports disabled, CMOS-level inputs). This value is specified in the DC Electrical Characteristics table for the L-version and reflects its ultra-low-power design optimized for battery-backed or energy-sensitive industrial applications.
