Product details
Overview
5962-9161707MXA from IDT is a military-grade 8K × 16-bit true dual-port static RAM with independent asynchronous left/right ports, 20ns/25ns/35ns/55ns/70ns access options, on-chip semaphore and BUSY arbitration logic, and 2V battery backup data retention - deployed in radar signal processors, avionics mission computers, and hardened real-time control systems.
For engineers reviewing the 5962-9161707MXA datasheet, 5962-9161707MXA pinout, 5962-9161707MXA application, or 5962-9161707MXA equivalent, key selection considerations include MIL-PRF-38535 QML certification, dual-port contention resolution timing (tBDD ≤ 45ns), 84-pin PGA package compatibility, and support for MASTER/SLAVE cascading to 32-bit+ bus widths without external logic.
Technical Context
The 5962-9161707MXA implements fully asynchronous dual-port operation with separate address, control, and I/O buses per port, enabling simultaneous read/write access to the same memory location only when BUSY arbitration prevents conflict. Its on-chip hardware semaphore logic uses A0–A2 addressing to manage eight shared flags across ports.
Arbitration is implemented via dedicated BUSY flag signaling (M/S = H for Master output, M/S = L for Slave input) and priority setup time (tAPS = 5ns), ensuring deterministic resolution during address-matched contention. The device supports TTL-compatible 5V ±10% supply and operates across –55°C to +125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
5962-9161707MXA is housed in an 84-pin ceramic PGA (PLG84) package with 1.15″ × 1.15″ body size and 0.100″ pin pitch. All VCC pins require local decoupling; all GND pins must be connected to system ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CEL / CER | Chip Enable (Left / Right) | Active-low enable per port; controls port activation and standby current entry (ISB1–ISB4) |
| R/WL / R/WR | Read/Write Control (Left / Right) | Determines direction of data transfer on respective port; asserts write when low |

| UBL / UBR, LBL / LBR | Upper/Lower Byte Select | Enables byte-level writes (I/O8–I/O15 or I/O0–I/O7), supporting 8-bit peripheral interfacing |
| SEML / SEMR | Semaphore Enable | Activates on-chip semaphore register access (A0–A2 addressed); disables RAM access when asserted |
| BUSYL / BUSYR | Busy Flag (Master Output / Slave Input) | M/S = H: BUSY output signals port contention; M/S = L: BUSY input gates write execution |
| INTL / INTR | Interrupt Flag | Open-drain push-pull output indicating semaphore or memory event; requires external pull-up |
| M/S | Master/Slave Select | Configures device role in cascaded systems: H = Master (BUSY output), L = Slave (BUSY input) |
Key Features
| Feature | Design Value |
|---|---|
| True Dual-Port Architecture | Enables concurrent read/write access from independent processors or DMA engines without software coordination |

FAQ
What is the maximum operating temperature range certified for 5962-9161707MXA?
The 5962-9161707MXA is qualified per MIL-PRF-38535 QML Class V for continuous operation from –55°C to +125°C ambient temperature. This rating is verified through temperature cycling, steady-state burn-in, and parametric testing across the full range - not extrapolated or derated. The 5962-9161707MXA maintains full 20ns access timing and data retention functionality throughout this envelope.
Does 5962-9161707MXA support true simultaneous read/write to the same address?
No - the 5962-9161707MXA prevents simultaneous conflicting access via hardware BUSY arbitration. When both ports attempt access to the same address, the BUSY flag asserts to stall the later-arriving port until the first completes. This deterministic contention resolution is defined by tBDD (BUSY Disable to Valid Data), which is ≤45ns for the 5962-9161707MXA at 70ns speed grade.
What package type is used for 5962-9161707MXA, and is it lead-free?
The 5962-9161707MXA uses an 84-pin ceramic Pin Grid Array (PLG84) package with tin-lead (SnPb) solder finish, compliant with MIL-STD-750 Method 2088 for hermeticity and MIL-STD-883 Method 2002 for shear strength. It is not RoHS-compliant due to Pb content - required for solder joint reliability under thermal shock in aerospace deployments.
How does the semaphore function work on 5962-9161707MXA?
The 5962-9161707MXA provides eight hardware semaphore flags accessed via A0–A2 address lines when SEM is low. Each flag is a single-bit register written via I/O0 and readable across all 16 I/O lines. Semaphore access is atomic and independent of main memory operations - enabling lock-free synchronization between processors without memory-mapped I/O overhead. The 5962-9161707MXA guarantees tSWRD ≤ 5ns for semaphore write-to-read turnaround.
Can 5962-9161707MXA be used in MASTER/SLAVE configuration for 32-bit bus expansion?
Yes - the 5962-9161707MXA supports cascaded MASTER/SLAVE operation using the M/S pin and BUSY handshaking. One device configured as MASTER (M/S = H) drives BUSY output to coordinate write sequencing; others as SLAVE (M/S = L) accept BUSY as input to gate writes. This enables seamless 32-bit+ data path expansion without external logic, preserving full-speed operation as specified in IDT Application Note AN-2683.
