Texas Instruments SM320F2812HFGM150

Overview

SM320F2812HFGM150 from Texas Instruments is a radiation-tolerant, high-performance 32-bit C28x DSP for demanding real-time control applications. It operates at 150 MHz (6.67-ns cycle time), integrates 128K × 16 Flash, 18K × 16 on-chip SARAM, dual 12-bit ADCs (16 channels, 12.5 MSPS), and two event managers (EVA/EVB) with 16 PWM outputs - deployed in motor drives, digital power supplies, and aerospace actuator controllers.

For engineers reviewing the SM320F2812HFGM150 datasheet, SM320F2812HFGM150 pinout, SM320F2812HFGM150 application, or SM320F2812HFGM150 equivalent, key selection criteria include its 172-pin HFG ceramic QFP package, −55°C to 125°C extended temperature range, 1.9-V core/3.3-V I/O supply, eCAN interface, and hardware-based code security with 128-bit password protection.

Technical Context

The SM320F2812HFGM150 implements the TMS320C28x CPU core with Harvard architecture, atomic instruction execution, and 4M linear program/data address reach. Its dual 12-bit ADC subsystem supports simultaneous sampling across two 8-channel multiplexers with 80-ns conversion time and integrated sample-and-hold circuits.

It features a programmable external memory interface (XINTF) with five zones, dynamic PLL ratio adjustment, watchdog timer, and peripheral interrupt expansion (PIE) supporting 45 interrupts. The device includes dedicated motor control peripherals: two event managers with 16 PWM outputs, 6 capture/QEP inputs, and trip-zone logic for overcurrent protection.

FAQ

What is the maximum operating frequency and required core voltage for SM320F2812HFGM150?

The SM320F2812HFGM150 operates at a maximum frequency of 150 MHz, which requires a 1.9-V core supply voltage. At 135 MHz, the core voltage may be reduced to 1.8 V. The 3.3-V I/O supply remains constant across both operating points, ensuring compatibility with standard logic interfaces and ADC reference levels. This voltage-frequency relationship is defined in TI's SGUS053B datasheet Section 6.2.

Does SM320F2812HFGM150 support simultaneous sampling across all 16 ADC channels?

No - the SM320F2812HFGM150 supports simultaneous sampling only between the two internal 8-channel ADC modules (ADC-A and ADC-B). Each module can sample its eight inputs simultaneously, but inter-module synchronization requires software coordination or external trigger alignment. The device does not provide hardware-triggered simultaneous start across all 16 channels in a single cycle.

What package type and temperature range does SM320F2812HFGM150 use?

The SM320F2812HFGM150 uses a 172-pin ceramic quad flatpack (HFG) package with hermetic sealing and is rated for operation from −55°C to 125°C. This package meets MIL-PRF-38535 requirements for high-reliability applications in aerospace, defense, and downhole industrial environments where moisture resistance and thermal stability are critical.

How does the 128-bit code security module function on SM320F2812HFGM150?

The 128-bit code security module on SM320F2812HFGM150 locks access to Flash, ROM, OTP, and secure SARAM blocks (L0/L1) until the correct password is written to the security register. Once enabled, it prevents read-back, debug access, and mass erase unless the password is re-entered. This protects firmware intellectual property and prevents unauthorized modification in deployed systems.

Is SM320F2812HFGM150 pin-compatible with other C28x family devices like SM320F28335?

No - the SM320F2812HFGM150 is not pin-compatible with SM320F28335 or other C28x derivatives. Although both use 172-pin HFG packages, the pin assignments differ significantly due to expanded peripherals (e.g., FPU, additional timers, single ADC) in the F28335. PCB layout and signal routing must be redesigned when migrating between these families.
