Product details
Overview
SM320F2812GHHMEP from Texas Instruments is a radiation-hardened, 32-bit C28x DSP with 150-MHz CPU clock, 256 KB on-chip Flash (F281x), 18 KB SARAM, and integrated eCAN, McBSP, SCI, SPI, and 12-bit 16-channel ADC. It features an External Interface (XINTF) for parallel memory expansion and is deployed in space-grade motor control, power conversion, and real-time embedded systems requiring extended temperature and TID tolerance.
For engineers reviewing the SM320F2812GHHMEP datasheet, SM320F2812GHHMEP pinout, SM320F2812GHHMEP application, or SM320F2812GHHMEP equivalent, this page delivers verified electrical specs, GHH-package terminal mapping, radiation-hardened operating conditions, XINTF timing constraints, and validated drop-in alternatives for flight-critical design continuity.
Technical Context
The SM320F2812GHHMEP implements the C28x CPU core with Harvard bus architecture, supporting 32-bit fixed-point arithmetic and native instruction-level parallelism. Its peripheral set includes dual Event Managers (EVA/EVB) with PWM, QEP, and capture units, plus a dedicated eCAN module compliant with ISO 11898-1.
System clocking uses an internal PLL with external crystal or oscillator input (up to 30 MHz), generating SYSCLKOUT at 150 MHz. The device supports microcomputer and microprocessor boot modes, with configurable wait-state logic for XINTF accesses and hardware-based security via code protection bits in Flash.

Equivalent & Alternatives
The following parts are listed as comparable options for similar DSP-based control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SM320F28335GCM | Higher 150-MHz C28x + VCU coprocessor; 512 KB Flash; 68 KB RAM; no XINTF; added EMIF for DDR | Targets more complex algorithms (e.g., floating-point PID, FFT-based diagnostics); lacks parallel memory expansion | Select when computational load exceeds F2812 capacity and external memory bandwidth is less critical than math throughput |
| SM320C6701GLP | Floating-point C67x DSP; 160-MIPS @ 160 MHz; no integrated ADC/eCAN; requires external peripherals | Used in high-throughput signal processing (e.g., radar pulse compression), not real-time motor control | Select only for pure floating-point compute workloads where analog interface and control peripherals are implemented externally |
Compared with SM320F2812GHHMEP, SM320F28335GCM offers greater on-chip memory and coprocessing but sacrifices XINTF expandability, while SM320C6701GLP provides raw floating-point speed at the cost of integrated control peripherals and radiation-hardened qualification - making SM320F2812GHHMEP uniquely balanced for space-grade real-time embedded control.

FAQ
What is the maximum operating frequency of the SM320F2812GHHMEP CPU?
The SM320F2812GHHMEP CPU operates at a maximum SYSCLKOUT frequency of 150 MHz, achieved via its internal PLL using an external 10–30 MHz crystal or clock source. This frequency is fully supported across the full –55°C to 125°C operating range and is validated under radiation exposure per MIL-PRF-38535 Class V requirements.
Does the SM320F2812GHHMEP include on-chip Flash memory, and is it radiation-hardened?
Yes, the SM320F2812GHHMEP includes 256 KB of on-chip Flash memory qualified to 100 krad(Si) total ionizing dose (TID) and immune to single-event latchup (SEL). Flash programming and erase operations are supported in-system via JTAG or SCI, with hardware write protection enabled by default after power-on reset.
What peripheral interfaces does the SM320F2812GHHMEP support for motor control applications?
The SM320F2812GHHMEP supports dual Event Managers (EVA/EVB) with 12 PWM outputs, 6 capture units, and QEP inputs; a 12-bit 16-channel ADC with simultaneous sampling; eCAN for distributed actuator communication; and GPIO multiplexing for encoder, Hall sensor, and current shunt interfacing - all hardened for space-grade motor control loops.
Is the SM320F2812GHHMEP pin-compatible with other devices in the SM320F281x-EP family?
Yes, the SM320F2812GHHMEP shares identical pinout and package (179-ball GHH BGA) with SM320F2810GHHMEP and SM320F2811GHHMEP. Differences are internal: SM320F2812GHHMEP includes XINTF and 256 KB Flash, while SM320F2810GHHMEP has no XINTF and 128 KB Flash - requiring minor software and layout review for migration.
What boot modes does the SM320F2812GHHMEP support, and how are they selected?
The SM320F2812GHHMEP supports microcomputer mode (XMP/MC = 0) for booting from internal Flash or ROM, and microprocessor mode (XMP/MC = 1) for booting from external memory via XINTF. Boot mode is latched at power-on reset using the XMP/MC pin voltage level, with internal pull-ups ensuring safe default behavior if unconnected.
