Renesas 7006L17PF

Overview

IDT7006L17PF from Integrated Device Technology (IDT) is a high-speed 16K × 8 dual-port static RAM with true independent left/right port access, 17 ns maximum read cycle time (tRC), 5 V ±10% single-supply operation, and industrial temperature range (–40°C to +85°C). It enables simultaneous reads of the same memory location and supports master/slave cascading for 16-bit+ bus expansion in real-time embedded control systems.

For engineers reviewing the IDT7006L17PF datasheet, IDT7006L17PF pinout, IDT7006L17PF application, or IDT7006L17PF equivalent, key selection considerations include its 17 ns access timing, low-power standby current (1 mW typ.), on-chip semaphore arbitration, BUSY flag logic, and compatibility with 64-pin TQFP packaging for space-constrained industrial controllers.

Technical Context

The IDT7006L17PF implements fully asynchronous dual-port architecture with separate address, data, and control buses per port-enabling concurrent read/write operations without external arbitration logic. Its on-chip arbitration logic resolves contention via BUSY flag assertion and supports both address-match and chip-enable arbitration modes.

It integrates full hardware semaphore signaling across ports using dedicated SEM pins and eight addressable semaphore flags (A0–A2), with tSWRD ≤ 5 ns write-to-read latency. The device operates in battery backup mode at 2 V with data retention, and features TTL-compatible I/Os with 0.4 V VOL and 2.4 V VOH under 4 mA load.

Manufacturer

Integrated Device Technology (IDT) was a fabless semiconductor company specializing in timing, memory interface, RF, and sensor solutions before its acquisition by Renesas Electronics in 2019. IDT's dual-port SRAMs were engineered for high-reliability embedded systems.

The IDT7006 family was designed specifically for real-time, multi-processor applications requiring deterministic memory access, hardware-enforced synchronization, and robust operation across extended temperature ranges-targeting industrial control, aerospace, and test equipment markets.

FAQ

What is the maximum operating frequency supported by the IDT7006L17PF?

The IDT7006L17PF has a maximum read cycle time (tRC) of 17 ns, corresponding to a theoretical maximum operating frequency of 58.8 MHz for continuous read operations. This timing is guaranteed over the full industrial temperature range (–40°C to +85°C) and 5 V ±10% supply, making it suitable for high-throughput data buffering in deterministic control loops. The device does not require clock input-it operates asynchronously.

Does the IDT7006L17PF support battery backup operation, and what voltage is required?

Yes, the IDT7006L17PF supports battery backup operation with guaranteed data retention at VCC = 2.0 V, as specified in its data retention characteristics table. In this mode, typical standby current is 100 µA (max 4000 µA for military grade), enabling extended holdover during main power loss. The 2 V threshold is validated across all temperature grades and requires no external circuitry-simply connect a 2 V backup source to VCC when main supply drops below 2.2 V.

How does the BUSY arbitration logic function in the IDT7006L17PF, and what are the timing constraints?

The IDT7006L17PF uses two arbitration methods: address-match and chip-enable. When M/S = VIH (master), BUSY is asserted within tBAA ≤ 17 ns of address match or tBAC ≤ 17 ns of CE assertion. For slave configuration (M/S = VIL), BUSY is an input that must be held high before write initiation. Critical timing parameters include tBDD ≤ 30 ns (BUSY disable to valid data) and tAPS = 5 ns (arbitration priority setup), ensuring deterministic resolution of port contention without software overhead.

Can the IDT7006L17PF be used in a 16-bit data bus configuration, and how is this implemented?

Yes, the IDT7006L17PF supports 16-bit (or wider) data bus expansion via master/slave cascading. Two devices are configured with M/S = VIH (master) and M/S = VIL (slave); the master's BUSY output connects to the slave's BUSY input. Address lines A0–A13 are paralleled, while I/O0–I/O7 of each device form the lower and upper byte lanes. This eliminates external glue logic and maintains full 17 ns access speed across the combined bus-verified in IDT's application notes for 16-bit memory systems.

What package type and pin count does the IDT7006L17PF use, and are thermal pads supported?

The IDT7006L17PF is packaged in a 64-pin Thin Quad Flatpack (TQFP) with 0.5 mm lead pitch and dimensions of 14 mm × 14 mm × 1.4 mm. It does not include an exposed thermal pad-the thermal design relies on the four VCC and four GND pins for heat dissipation. The package complies with JEDEC MO-153 and is RoHS-compliant; recommended PCB layout uses solid ground planes beneath the device and 10-mil minimum trace widths for power distribution.
