Product details
Overview
5962-9455803QXA from Texas Instruments is a radiation-hardened, military-grade 16-bit fixed-point digital signal processor (DSP) designed for real-time signal processing in spaceborne and high-reliability embedded systems. It features a 30 ns instruction cycle time (66 MHz operation), 9K × 16-bit on-chip single-cycle program/data RAM, 32-bit ALU with dual 32-bit accumulators, and IEEE 1149.1 boundary scan support - enabling use in satellite telemetry processing, radar pulse compression, and hardened avionics control.
For engineers reviewing the 5962-9455803QXA datasheet, 5962-9455803QXA pinout, 5962-9455803QXA application, or 5962-9455803QXA equivalent, this page delivers verified technical context, exact package mapping to the 132-lead ceramic quad flat package (HFG), confirmed terminal functions per MIL-PRF-38535 Class B testing, and validated alternatives for radiation-tolerant DSP migration paths.
Technical Context
The 5962-9455803QXA implements a fully static EPIC™ CMOS architecture with a four-deep instruction pipeline supporting delayed branching and subroutine calls, delivering ≥2× performance over SMJ320C2x predecessors. Its parallel logic unit (PLU) enables bit manipulation independent of the ALU/accumulator, while dual-access 1056 × 16-bit data RAM supports simultaneous read/write operations for efficient FFT and filter coefficient handling.
Timing control is managed via dual serial ports (full-duplex synchronous + TDM), a programmable 16-bit timer with counter registers, and 16 software-configurable wait-state generators. Clocking flexibility includes external divide-by-one (CLKIN2) or divide-by-two (X2/CLKIN) modes, with boundary scan test access enabled by IEEE 1149.1-compliant TAP controller and TRST/TCK/TMS/TDI/TDO pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Instruction Cycle Time | 30 ns - enables 66 MHz sustained execution for real-time FIR/IIR filtering at ≤100 kHz sample rates |
| On-Chip RAM | 9K × 16-bit single-cycle program/data RAM - eliminates external memory latency for critical kernel code |
| ALU Width | 32-bit arithmetic logic unit with ACC/ACCB registers - supports extended-precision accumulation without overflow in 16-bit data paths |
| Serial Interfaces | Full-duplex synchronous + TDM serial port - allows simultaneous voice/data channel aggregation in secure comms systems |
| Operating Temperature | –55°C to +125°C case temperature - qualified per MIL-PRF-38535 for deployment in orbital thermal vacuum environments |
| Supply Voltage | 4.75 V to 5.25 V - TTL-compatible I/O with VOH ≥2.4 V and VOL ≤0.6 V ensures interoperability with legacy 5 V logic |
| Power Consumption | 7 μA in IDLE2 mode - enables ultra-low-power standby during satellite eclipse periods without losing register state |
Pinout & Package
5962-9455803QXA is packaged in a 132-lead ceramic quad flat package (HFG suffix), compliant with MIL-STD-883 Class B screening and processed to MIL-PRF-38535 requirements. The package provides 132 terminally defined I/O, power, and ground connections with dedicated VDD/VSS groups for bus, address, memory control, and logic domains.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A15 | Address Bus (I/O/Z) | 16-bit multiplexed address output for external program/data/I/O space selection; tri-stated during HOLD or OFF |
| D0–D15 | Data Bus (I/O/Z) | 16-bit bidirectional data path with automatic direction control via R/W; used for DMA access to on-chip RAM |
| CLKIN2 | Divide-by-One Clock Input | Accepts 66 MHz external clock directly; bypasses internal oscillator to achieve full 30 ns cycle time without crystal load |
| TCK/TMS/TDI/TDO/TRST | JTAG Boundary Scan Interface | IEEE 1149.1-compliant test access port enabling in-system verification, fault isolation, and configuration programming |
| EMU0/EMU1/OFF | Emulation Control | Configurable debug interface: EMU1/OFF becomes OFF signal when TRST = low, forcing all outputs into high-Z for safe probing |
| VDD1–VDD16 / VSS1–VSS16 | Decoupled Power/Ground | 16 dedicated supply pins segmented by functional domain - reduces switching noise coupling between data/address/memory control circuits |
Key Features
| Feature | Design Value |
|---|---|
| Fully Static CMOS Core | Enables zero-clock-stop operation - critical for radiation-induced single-event latchup recovery without system reset |
| Dual-Access Data RAM | 1056 × 16-bit memory bank supports concurrent read/write for pipelined FFT butterfly operations |
| Parallel Logic Unit (PLU) | 16-bit bit-manipulation engine operating independently of ALU - accelerates bit-field extraction in telemetry decoding |
| IDLE2 Low-Power Mode | Reduces current to 7 μA by disabling internal clocks while preserving register contents - extends battery life in dormant payloads |
| Hardware Wait-State Generators | 16 software-programmable wait states per memory space - accommodates slow PROMs or FPGA-based peripherals without firmware overhead |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital signal processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMJ320C6701GBZL | 32-bit floating-point architecture; 167 MHz peak; 256K × 32-bit L2 cache; no MIL-PRF-38535 Class B rating | Higher precision for adaptive beamforming; unsuitable for radiation-hardened spaceflight due to lack of QML certification | Select only for ground-based radar test benches requiring floating-point math not supported by 5962-9455803QXA |
| 5962-0320901VXC | Same C50 core; 40 ns cycle time (50 MHz); identical HFG package; MIL-PRF-38535 Class B qualified | Lower throughput for bandwidth-constrained telemetry links; same radiation tolerance and thermal range | Choose when system timing margins allow relaxed 40 ns cycles - reduces power draw by ~15% vs. 5962-9455803QXA |
Compared with 5962-9455803QXA, SMJ320C6701GBZL offers higher computational precision but lacks radiation hardening, while 5962-0320901VXC provides identical reliability at reduced clock speed - making it a drop-in thermal/power alternative where 66 MHz is unnecessary.

FAQ
What is the maximum operating frequency of the 5962-9455803QXA?
The 5962-9455803QXA operates at a maximum clock frequency of 66 MHz, achieving a 30 ns instruction cycle time. This is realized using the external divide-by-one clock option with CLKIN2 input, as specified in the SGUS020B datasheet. The device maintains full functionality across its –55°C to +125°C case temperature range at this speed, with power supply regulated to 4.75 V–5.25 V.
Does the 5962-9455803QXA support IEEE 1149.1 boundary scan?
Yes, the 5962-9455803QXA integrates full IEEE 1149.1 boundary scan logic with dedicated TCK, TMS, TDI, TDO, and TRST pins. It complies with IEEE Std 1149.1-1990 and supports in-system test, interconnect verification, and emulation-mode debugging - essential for validating PCB assemblies in high-reliability aerospace applications where physical probe access is limited.
How does the IDLE2 instruction reduce power consumption in the 5962-9455803QXA?
The IDLE2 instruction halts the functional clock to all internal hardware blocks of the 5962-9455803QXA, placing it into total-sleep mode drawing only 7 μA at 125°C and 5.25 V. Unlike standard IDLE, IDLE2 preserves all register contents and memory state, allowing immediate resumption upon external interrupt - a critical capability for satellite systems requiring rapid response after orbital eclipse periods.
What memory architecture does the 5962-9455803QXA use for real-time signal processing?
The 5962-9455803QXA employs a dual-memory architecture: 9K × 16-bit single-cycle on-chip program/data RAM for zero-wait-state kernel execution, and 1056 × 16-bit dual-access data RAM enabling simultaneous read/write operations. This structure supports pipelined FFTs and FIR filters without memory contention - a key advantage over external-memory-dependent DSPs in latency-critical applications like radar pulse compression.
Is the 5962-9455803QXA pin-compatible with other SMJ320C50 variants?
Yes, the 5962-9455803QXA shares identical pinout and electrical characteristics with other HFG-package SMJ320C50 devices, including SMJ320C50HFGM66 and SMJ320C50HFGM50. All HFG variants use the same 132-lead ceramic quad flat package with matching terminal assignments, power/ground pin distribution, and I/O voltage tolerances - enabling direct substitution in existing designs qualified to MIL-PRF-38535.
