Product details
Overview
5962-8861901XA from Texas Instruments is a radiation-hardened, military-grade 16-bit digital signal processor (DSP) designed for real-time signal processing in tactical communications, guidance systems, and spectrum analysis. It features a 100-ns instruction cycle time, 544 words of on-chip data RAM, 4K words of on-chip program ROM, a 16 × 16-bit hardware multiplier with 32-bit product, and a 32-bit ALU/accumulator - enabling 12.5 MIPS execution in embedded control and filtering applications.
For engineers reviewing the 5962-8861901XA datasheet, 5962-8861901XA pinout, 5962-8861901XA application, or 5962-8861901XA equivalent, this page delivers verified technical context, military temperature range (-55°C to 125°C), 68-pin ceramic package mapping, serial port interface details, and confirmed alternatives for high-reliability DSP system design.
Technical Context
The 5962-8861901XA implements a Harvard architecture with separate 16-bit program and data buses, supporting single-cycle multiply/accumulate (MAC) instructions and block memory transfers. Its eight auxiliary registers with dedicated arithmetic unit enable efficient indirect addressing for FFTs and adaptive filtering.
It integrates a full-duplex serial port (DR/DX/CLKR/CLKX/FSR/FSX), on-chip 16-bit timer with period register (PRD), global memory arbitration via BR/READY signals, and microprocessor/microcomputer mode selection (MP/MC) - all operating from a single 5-V supply using 1.6-µm CMOS technology.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Instruction Cycle Time | 100 ns - enables 12.5 million instructions per second (MIPS) for real-time filtering and control loops. |
| On-Chip Data RAM | 544 × 16-bit words - split into three configurable blocks (B0/B1/B2) for flexible data/program memory partitioning. |
| On-Chip Program ROM | 4K × 16-bit words - mask-programmed storage for boot code or fixed algorithms, eliminating external ROM dependency. |
| Multiplier | 16 × 16-bit hardware unit with 32-bit product register - supports single-cycle MAC for FIR/IIR filter kernels. |
| ALU/Accumulator | 32-bit ALU with dual 16-bit accumulator segments (ACCH/ACCL) - enables extended-precision arithmetic and normalization. |
| Memory Address Space | 128K words total (64K program + 64K data) - supports external memory expansion with wait-state control via READY input. |
| Operating Temperature | –55°C to +125°C - qualified per MIL-PRF-38535 Class V for space and defense platforms. |
Pinout & Package
5962-8861901XA is packaged in a 68-pin ceramic leaded chip carrier (FJ suffix), 68-pin ceramic grid array (GB suffix), or 68-pin leadless ceramic chip carrier (FD suffix), all compliant with military hermetic sealing requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D15–D0 | 16-bit bidirectional data bus | Multiplexed across program/data/I/O spaces; high-impedance during HOLD to support DMA. |
| A15–A0 | 16-bit address bus output | Drives external memory/peripherals; supports 64K-word addressing per space (PS/DS/IS). |
| PS/DS/IS | Memory space select outputs | Active-low signals that decode program/data/I/O access - essential for memory-mapped peripheral interfacing. |
| R/W | Read/write control | Active-low signal indicating direction of data transfer on D15–D0 bus. |
| STRB | Strobe output | Indicates valid address/data setup for external latch capture in asynchronous interfaces. |
| INT0–INT2 | Maskable interrupt inputs | Level-sensitive, priority-encoded inputs for external event handling (e.g., ADC EOC, sensor trigger). |
| BR/HOLD | Bus request / hold inputs | Enable multiprocessor global memory arbitration (BR) and external DMA takeover (HOLD). |
| XF | Programmable flag output | Software-controlled general-purpose output for signaling external logic or status indication. |
Key Features
| Feature | Design Value |
|---|---|
| Single-cycle MAC with data move | Enables zero-overhead loop execution of filter taps without pipeline stalls or additional memory fetches. |
| Eight auxiliary registers + ARAU | Supports bit-reversal, auto-increment/decrement, and post-indexed addressing - critical for FFT and convolution kernels. |
| Global memory allocation register (GREG) | 8-bit memory-mapped register defining size of shared external data space for multiprocessor synchronization. |
| Repeat instruction (RPT/RPTK) | Executes next instruction up to 256 times with no loop overhead - reduces code footprint and improves cache efficiency. |
| Hardware timer with reload (TIM/PRD) | Generates precise periodic interrupts at intervals of (PRD + 1) × CLKOUT1 cycles - ideal for sampling control and watchdog timing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital signal processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 5962-8861902XA | 80-ns instruction cycle time (12.5 MIPS → 12.5 MIPS base, but higher sustained throughput due to faster memory interface). | Preferred for latency-critical radar pulse compression where every nanosecond of MAC delay matters. | Select when system-level timing budget requires ≤80 ns per instruction and external memory supports faster access. |
| SMJ320C30 | 32-bit floating-point architecture, 33-MHz clock, Harvard+Von Neumann hybrid; no on-chip ROM, larger external memory footprint required. | Used in newer avionics upgrades requiring IEEE-754 compliance and higher dynamic range than fixed-point C25 permits. | Choose for floating-point-intensive applications like synthetic aperture radar (SAR) imaging where precision outweighs radiation hardness trade-offs. |
Compared with 5962-8861901XA, the 5962-8861902XA offers identical pinout and firmware compatibility but improved cycle time, while the SMJ320C30 provides architectural scalability at the cost of increased board area, power, and qualification revalidation effort.

FAQ
What is the maximum operating frequency of the 5962-8861901XA?
The 5962-8861901XA operates with a 100-ns instruction cycle time, corresponding to a maximum internal execution rate of 10 MHz. Its on-chip clock generator derives CLKOUT1 and CLKOUT2 from X1/X2 crystal or external CLKIN, with CLKOUT1 = CLKIN/4. The device does not specify a maximum crystal frequency beyond this ratio, and timing validation must be performed per MIL-PRF-38535 Class V test conditions.
Does the 5962-8861901XA support floating-point operations?
The 5962-8861901XA does not contain hardware floating-point units. However, its instruction set explicitly supports floating-point operations through software libraries - including normalized mantissa/exponent manipulation, extended-precision arithmetic primitives, and adaptive filtering routines optimized for its 32-bit accumulator and scaling shifter.
How is external memory interfaced to the 5962-8861901XA?
The 5962-8861901XA uses PS/DS/IS address space select lines, R/W control, STRB strobe, and READY handshake to interface with external memory. READY allows insertion of wait states for slow devices; BR/HOLD signals enable global memory arbitration and DMA access. Address and data buses are time-multiplexed only in microcomputer mode, not in microprocessor mode.
What packaging options are available for the 5962-8861901XA?
The 5962-8861901XA is offered in three hermetically sealed ceramic packages: 68-pin Leaded Ceramic Chip Carrier (FJ), 68-pin Ceramic Grid Array (GB), and 68-pin Leadless Ceramic Chip Carrier (FD). All meet MIL-STD-883 requirements for thermal cycling, mechanical shock, and humidity resistance.
Is the 5962-8861901XA pin-compatible with other SMJ320 family members?
The 5962-8861901XA shares identical pinout and electrical characteristics with the 5962-8861902XA (80-ns variant) across all three package types (FJ/GB/FD). It is not pin-compatible with later-generation SMJ320C30 or SMJ320C40 devices due to architectural differences in bus structure, memory mapping, and peripheral integration.
