Texas Instruments SM320F2812HFGS150

Overview

SM320F2812HFGS150 from Texas Instruments is a radiation-tolerant, high-temperature digital signal processor (DSP) based on the C28x CPU core, operating at 150 MHz with 128 KB on-chip Flash, 18 KB SARAM, and integrated eCAN, McBSP, SCI, SPI, ADC, and PWM peripherals. It targets real-time motor control, power conversion, and avionics systems requiring extended temperature operation.

For engineers reviewing the SM320F2812HFGS150 datasheet, SM320F2812HFGS150 pinout, SM320F2812HFGS150 application, or SM320F2812HFGS150 equivalent, key selection criteria include its 172-pin HFG CQFP package, -55°C to +125°C operating range, 12-bit 16-channel ADC with 200 ns conversion time, dual event managers with quadrature encoder support, and eCAN 2.0B compliance for deterministic communication in harsh environments.

Technical Context

The SM320F2812HFGS150 implements a Harvard architecture with separate program and data buses, enabling simultaneous instruction fetch and data access. Its C28x CPU delivers 300 MIPS peak performance and supports IEEE 754 single-precision floating-point emulation via IQmath libraries.

Real-time control is enabled by two independent Event Manager modules (EVA/EVB), each providing six PWM outputs, quadrature encoder pulse (QEP) inputs, capture units, and programmable dead-band generation - all synchronized to a common 150-MHz SYSCLKOUT derived from an internal PLL with external crystal or oscillator input.

FAQ

What is the maximum operating temperature rating for the SM320F2812HFGS150?

The SM320F2812HFGS150 is fully specified and tested from -55°C to +125°C ambient temperature. This extended temperature range is achieved through process hardening, hermetic HFG CQFP packaging, and rigorous burn-in screening - making it suitable for spacecraft, jet engines, and deep-well drilling tools where commercial-grade parts cannot survive.

Does the SM320F2812HFGS150 include on-chip Flash memory, and is it secure?

Yes, the SM320F2812HFGS150 integrates 128 KB of on-chip Flash memory organized in eight 16-KB sectors. It features a code-security module that prevents external readback of Flash contents via JTAG or boot ROM interfaces - protecting proprietary motor control algorithms and calibration data in deployed SM320F2812HFGS150 systems.

How many PWM outputs does the SM320F2812HFGS150 support, and are they synchronized?

The SM320F2812HFGS150 provides twelve independent PWM outputs - six from Event Manager A (EVA) and six from Event Manager B (EVB). All twelve can be precisely synchronized using the ePWM sync signal, enabling coordinated three-phase inverter control, interleaved converters, or multi-axis motor drives without external logic.

What ADC resolution and sampling speed does the SM320F2812HFGS150 offer?

The SM320F2812HFGS150 includes a 12-bit analog-to-digital converter with 16 input channels and a minimum conversion time of 200 ns. It supports both sequential (single-channel) and simultaneous (dual-channel) sampling modes - critical for accurate three-phase current reconstruction in real-time motor control applications using the SM320F2812HFGS150.

Is the SM320F2812HFGS150 pin-compatible with other C28x-family devices?

No, the SM320F2812HFGS150 is not pin-compatible with later C28x devices such as the F28335 or F28379D. Its 172-pin HFG CQFP footprint, power sequencing requirements (VDD before VDDIO), and peripheral pin mappings are unique to the F2812 generation. Migration to newer devices requires PCB redesign and firmware adaptation for the SM320F2812HFGS150.
