Product details
Overview
5962-8861901ZA from Texas Instruments is a radiation-hardened, military-grade 16-bit fixed-point digital signal processor (DSP) designed for real-time signal processing in tactical communications, guidance systems, and embedded control. It features a 100-ns instruction cycle time, 544 words of on-chip data RAM, 4K words of on-chip program ROM, a 32-bit ALU/accumulator, and single-cycle multiply/accumulate capability.
For engineers reviewing the 5962-8861901ZA datasheet, 5962-8861901ZA pinout, 5962-8861901ZA application, or 5962-8861901ZA 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 validated alternatives for high-reliability DSP design.
Technical Context
The 5962-8861901ZA implements a Harvard architecture with separate 16-bit program and data buses, enabling simultaneous instruction fetch and operand access. Its 32-bit ALU operates on accumulator contents with dedicated input paths from the 16×16-bit multiplier's 32-bit product register and scaling shifter output.
Memory control includes dynamic configuration of on-chip Block B0 as either program or data space via CNFD/CNFP instructions, while external memory interfacing uses PS/DS/IS space-select signals, R/W, STRB, and READY for wait-state management across program, data, and I/O address spaces.

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital signal processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 5962-8861901RA | 80-ns instruction cycle time; higher 12.5 MIPS throughput vs. 10-MIPS 5962-8861901ZA | Preferred for latency-critical radar pulse compression where every 20 ns reduces processing delay | Select when maximum computational throughput is required and timing margins allow tighter clock constraints |
| SMJ320C25-50 | Commercial/military hybrid variant; identical architecture but non-radiation-hardened, non-Class V qualified | Suitable for ground-test benches or non-flight subsystems where radiation tolerance is not mandated | Choose for cost-sensitive development platforms where full QML qualification is unnecessary |
Compared with 5962-8861901ZA, the 5962-8861901RA offers faster deterministic execution at the expense of stricter timing closure, while SMJ320C25-50 provides architectural parity without radiation hardening-making it viable only in non-space, non-nuclear environments.

FAQ
What is the maximum operating frequency of the 5962-8861901ZA?
The 5962-8861901ZA has a 100-ns instruction cycle time, corresponding to a maximum clock frequency of 10 MHz derived from CLKIN or crystal oscillator input. CLKOUT1 operates at one-quarter of CLKIN frequency and serves as the primary system clock reference for external logic and the on-chip timer.
Does the 5962-8861901ZA support floating-point operations?
The 5962-8861901ZA 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 functions-all optimized for its 32-bit accumulator and scaling shifter.
How is external memory interfaced to the 5962-8861901ZA?
The 5962-8861901ZA uses three dedicated memory space select signals (PS, DS, IS), a 16-bit address bus (A0–A15), and a 16-bit bidirectional data bus (D0–D15). Wait states are controlled via the READY input, allowing seamless interfacing with slower PROMs, SRAMs, or peripheral ICs without additional glue logic.
What packaging options are available for the 5962-8861901ZA?
The 5962-8861901ZA is offered exclusively in hermetic 68-pin ceramic packages: leaded ceramic chip carrier (FJ suffix), ceramic grid array (GB suffix), and leadless ceramic chip carrier (FD suffix). All variants meet MIL-STD-883 requirements for thermal cycling, mechanical shock, and humidity resistance.
Can the 5962-8861901ZA operate in multiprocessor configurations?
Yes-the 5962-8861901ZA supports synchronous multiprocessor operation via the SYNC input, BR/HOLD bus arbitration signals, and the 8-bit GREG register. It can function as master, slave, or peer in global memory-sharing topologies, with hardware-enforced bus request and hold acknowledgment sequencing.
