Renesas 5962-8861011ZA

Overview

5962-8861011ZA from Integrated Device Technology (IDT) is a military-grade 2K × 16-bit dual-port static RAM with independent left/right asynchronous ports, 35ns maximum read cycle time, on-chip port arbitration logic (MASTER mode), and BUSY flag signaling for contention resolution - deployed in radar signal processors and avionics real-time data buffers.

For engineers reviewing the 5962-8861011ZA datasheet, 5962-8861011ZA pinout, 5962-8861011ZA application, or 5962-8861011ZA equivalent, this page delivers verified military-spec timing parameters, dual-port arbitration behavior, 68-pin PGA package mapping, battery backup capability (2V data retention), and direct MASTER/SLAVE expansion compatibility with IDT7143 devices.

Technical Context

The 5962-8861011ZA 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. It integrates on-chip arbitration logic exclusive to MASTER configuration (IDT7133 variant), generating open-drain BUSYL/BUSYR outputs that require external pull-up resistors.

It supports TTL-compatible 5V ±10% single-supply operation across –55°C to +125°C, meets MIL-PRF-38535 QML Class V requirements, and provides byte-level write enable (R/WLUB/R/WLLB and R/WRUB/R/WRLB) for precise data masking - critical for deterministic interrupt-driven buffer management in hardened embedded systems.

FAQ

What is the qualified operating temperature range for 5962-8861011ZA?

The 5962-8861011ZA is qualified for continuous operation from –55°C to +125°C per MIL-PRF-38535 QML Class V requirements. This range is validated across all electrical parameters including tRC = 35 ns max, ISB1 ≤ 70 mA, and VDR = 2.0 V minimum - ensuring reliability in jet engine bays, missile canisters, and space-qualified payloads where thermal extremes are routine.

Does 5962-8861011ZA support battery backup operation?

Yes, 5962-8861011ZA supports battery backup operation with guaranteed data retention at VCC = 2.0 V minimum. The LA variant (indicated by 'LA' in IDT7133LA/7143LA nomenclature) draws ≤4000 µA in retention mode at military temperature extremes, enabling seamless hold during main power interruption in flight control computers and guidance units.

How does the BUSY arbitration logic function in 5962-8861011ZA?

In 5962-8861011ZA (IDT7133 MASTER variant), BUSYL and BUSYR are open-drain outputs that assert when both ports attempt simultaneous access to the same memory address. The on-chip arbitration logic ensures one port proceeds while the other is stalled - preventing data corruption. External pull-up resistors are mandatory, and BUSY signals can be OR'd to generate system-level contention interrupts.

What package type is used for 5962-8861011ZA?

5962-8861011ZA uses a 68-pin ceramic PGA (GU68) package with hermetic sealing, measuring approximately 1.18 in × 1.18 in × 0.16 in. It features dual VCC (pins 51, 36) and dual GND (pins 35, 68) connections - both sets must be independently wired to ensure stable operation under shock, vibration, and thermal cycling in aerospace deployments.

Can 5962-8861011ZA be used with IDT7143 SLAVE devices for 32-bit bus expansion?

Yes, 5962-8861011ZA (IDT7133 MASTER) is explicitly designed to pair with IDT7143 SLAVE devices for 32-bit-or-wider memory expansion. The MASTER generates BUSY signals that inhibit writes on SLAVE devices during contention, eliminating "Busy Lock-Out" - a known failure mode in multi-chip dual-port systems without coordinated arbitration.
