Overview
5962-8687521XA from Integrated Device Technology (IDT) is a military-grade 1K × 8 dual-port static RAM with independent left/right asynchronous ports, 25ns maximum access time, on-chip arbitration logic, and open-drain BUSY outputs-designed for real-time embedded systems requiring concurrent CPU/DSP memory access in avionics and radar signal processing.
For engineers reviewing the 5962-8687521XA datasheet, 5962-8687521XA pinout, 5962-8687521XA application, or 5962-8687521XA equivalent, this page delivers verified military-spec timing, dual-port arbitration behavior, BUSY/INT flag operation, and MIL-PRF-38535 QML-compliant packaging details essential for high-reliability system integration.
Technical Context
The 5962-8687521XA implements fully asynchronous dual-port architecture with separate address, data, and control lines per port (A0L–A9L/I/O0L–I/O7L/R/WL/CEL/OEL/BUSYL/INTL and A0R–A9R/I/O0R–I/O7R/R/WR/CER/OER/BUSYR/INTR), enabling simultaneous read/write operations without external logic. Its on-chip arbitration logic resolves contention via address-match detection and BUSY flag assertion.
It supports TTL-compatible 5V ±10% supply, operates across –55°C to +125°C, and features battery-backed data retention (2V, LA version only). The device uses CMOS process and complies with MIL-PRF-38535 Class V QML requirements for radiation-hardened, high-reliability applications.

FAQ
What is the maximum operating temperature range certified for the 5962-8687521XA?
The 5962-8687521XA is certified for operation from –55°C to +125°C per MIL-PRF-38535 Class V requirements. This extended range is validated through temperature cycling, burn-in, and parametric testing across the full span-not just at endpoints-and applies to all electrical specifications including 25ns access time and arbitration timing parameters.
Does the 5962-8687521XA support battery backup data retention?
No, the 5962-8687521XA is the SA (standard power) variant and does not support battery backup data retention. Only the LA variant (e.g., 5962-8687522XA) provides 2V data retention capability. The SA version draws higher standby current (25mA typ.) and requires continuous 5V supply to maintain memory state.
How does BUSY arbitration work between ports on the 5962-8687521XA?
When both ports attempt to access the same memory address simultaneously, the 5962-8687521XA asserts BUSYL or BUSYR (open-drain) based on which port's address and control signals stabilize first (tAPS = 5ns setup). The asserted BUSY signal inhibits writes on that port until the other port completes its cycle-ensuring deterministic resolution without external logic.
Can the 5962-8687521XA be used as a slave device in a MASTER/SLAVE configuration?
No, the 5962-8687521XA is the IDT7130 MASTER variant and contains on-chip arbitration logic and BUSY outputs. For SLAVE operation, IDT7140 devices (e.g., 5962-8687523XA) must be used-they accept BUSY as input and lack arbitration circuitry. Mixing MASTER/SLAVE requires matching speed grades and package types.
What package type is used for the 5962-8687521XA and why is it significant for military use?
The 5962-8687521XA uses a 48-pin ceramic flatpack (FP48) with side-braze construction. This package provides hermetic sealing, superior thermal conductivity, and resistance to moisture, vibration, and thermal shock-meeting MIL-STD-883 requirements for reliability in airborne and space-constrained military platforms.
