Renesas 5962-8866515ZA

Overview

5962-8866515ZA from Integrated Device Technology (IDT) is a military-grade, high-speed 2K × 16 dual-port static RAM with independent left/right ports, 35ns max read cycle time, on-chip arbitration logic, and open-drain BUSY output - designed as the MASTER device in width-expanded memory systems for real-time avionics and radar signal processing.

For engineers reviewing the 5962-8866515ZA datasheet, 5962-8866515ZA pinout, 5962-8866515ZA application, or 5962-8866515ZA equivalent, this page delivers verified military-spec timing, true dual-port arbitration behavior, battery-backed data retention at 2V, and precise 68-pin ceramic PGA package mapping - critical for QML-38535-compliant system integration.

Technical Context

The 5962-8866515ZA implements fully asynchronous dual-port operation with separate address, control, and I/O buses per port, enabling concurrent read/write access to any memory location without internal synchronization overhead. Its on-chip arbitration logic resolves port contention via BUSY flag assertion with deterministic priority setup (tAPS = 5ns min).

As the MASTER device in IDT's MASTER/SLAVE architecture, it drives BUSY as an open-drain output requiring external pull-up, while supporting width expansion to 32-bit+ systems using SLAVE IDT7143 devices. It operates across –55°C to +125°C with single 5V ±10% supply and retains data at VCC = 2V.

FAQ

What is the operating temperature range for the 5962-8866515ZA?

The 5962-8866515ZA is rated for –55°C to +125°C ambient operation and qualified per MIL-PRF-38535 Class V. This full military temperature range ensures reliable functionality in jet engine bays, radar transmitters, and space-qualified payloads where thermal cycling exceeds commercial or industrial limits. The 5962-8866515ZA maintains specified timing and data retention across this entire range without derating.

Does the 5962-8866515ZA include on-chip arbitration logic?

Yes, the 5962-8866515ZA integrates on-chip arbitration logic and functions as the MASTER device in IDT's MASTER/SLAVE dual-port architecture. It asserts BUSYL/BUSYR as open-drain outputs to signal port contention, with tAPS = 5 ns minimum priority setup time. This eliminates the need for external arbitration circuitry in synchronized multi-processor systems - a key feature distinguishing the 5962-8866515ZA from SLAVE-only variants like IDT7143.

What package type is used for the 5962-8866515ZA?

The 5962-8866515ZA is supplied in a 68-pin ceramic PGA (PLG68) package, measuring approximately 0.95″ × 0.95″ × 0.17″. It features two dedicated VCC and two GND pins, all of which must be connected per MIL-PRF-38535 requirements to ensure signal integrity and thermal stability in high-vibration military platforms. Pin compatibility is maintained across IDT7133/7143 family members.

Can the 5962-8866515ZA retain data at reduced supply voltage?

Yes, the 5962-8866515ZA supports battery backup operation with guaranteed data retention at VCC = 2.0 V (minimum), as confirmed in Table 8 of the official datasheet. This capability enables uninterrupted memory state preservation during main power failure in mission-critical avionics - such as inertial navigation updates or radar track files - without requiring external SRAM controllers or backup supervisors.

How does the 5962-8866515ZA differ from the IDT7143 series?

The 5962-8866515ZA is a military-qualified variant of the IDT7133 MASTER dual-port SRAM, featuring on-chip arbitration logic and BUSY output functionality. In contrast, IDT7143 devices are SLAVE-only parts with BUSY inputs (not outputs) and no internal arbitration. The 5962-8866515ZA enables width expansion to 32-bit+ systems when paired with IDT7143 SLAVES - a capability the IDT7143 alone cannot provide.
