SMJ320F2812HFGM150

Digital Signal Processor Dsp Overview

The SMJ320F2812HFGM150 is a radiation-hardened digital signal processor based on the TMS320C28x architecture. It operates at clock frequencies up to 150 MHz with a cycle time of 6.67 ns. The device features a 1.8-V core (supporting 135 MHz) or 1.9-V core (supporting 150 MHz) and 3.3-V I/O. Memory includes 128K x 16 Flash, 18K x 16 SARAM, and 1K x 16 OTP ROM. It integrates dual event managers, a 12-bit ADC with 16 channels, eCAN, SPI, two SCIs, and McBSP. The HFG variant utilizes a 172-pin ceramic quad flatpack package and supports an extended temperature range from -55°C to 125°C.

Digital Signal Processor Dsp Feature Summary

• Dual Event Managers for motor control applications
• 12-Bit ADC with 16 multiplexed input channels
• 172-Pin Ceramic Quad Flatpack (HFG) package

Digital Signal Processor Dsp Applications

• Spacecraft attitude control systems
• Radiation-hardened motor drives
• Avionics signal processing
• Harsh environment industrial control

Digital Signal Processor Dsp Procurement Notes

Verify that the specific suffix 'HFG' corresponds to the 172-pin ceramic quad flatpack package and that the 'M' temperature grade covers the required -55°C to 125°C operational range. Confirm radiation hardness specifications against mission requirements, as these are distinct from standard commercial F2812 variants.

Digital Signal Processor Dsp Selection Notes

Select this model when radiation tolerance is mandatory. Ensure power supply design accommodates the separate 1.8-V/1.9-V core voltage and 3.3-V I/O/Flash voltage rails. The HFG package requires specific PCB footprint considerations compared to plastic packages like PGF or GHH.

Digital Signal Processor Dsp Part Context

This component belongs to the SMJ320F2812 family, which represents the space/radiation-hardened version of the TMS320F2812 DSP. While functionally similar to the commercial F2812, it undergoes specialized processing to withstand ionizing radiation effects common in aerospace and defense environments.

Digital Signal Processor Dsp Replacement Considerations

SM320F2812HFG: Commercial equivalent without radiation hardening. TMS320F2812PGFA: Commercial equivalent in LQFP-176 package.
