Exceeding the traditional 150 °C limit for other high-temperature semiconductors, the SM320F28335-HT Delfino 32-bit MCU provides high-reliability, high-performance, real-time measurement and control for manufacturers of electronics operating in harsh and hot environments, such as downhole drilling, commercial jet engines, motor control, military applications, and medical instruments and surgical tools requiring sterilization.

The SM320F28335-HT Delfino MCU is based on the companys popular TMS320C2000™ MCU platform, which combines control peripheral integration and embedded flash memory with the processing power of a 32-bit floating-point architecture. Enabling operation at up to 210 °C eliminates the need for expensive up-screening and qualification tests of industrial grade MCUs, allowing for faster design of applications operating in harsh environments and cutting development time by up to one year. Packaging options, such as a 181-pin ceramic PGA and Known Good Die (KGD), provide the smallest form factors for space-constrained applications.

The TMS320F28335 Experimenter Kit, which is based on the commercial grade, code-compatible version of the F28335 Delfino MCU, is also immediately available for experimentation and code development for the new high-temperature version. The kit is priced at $99.

The MCU features an integrated 32-bit floating-point unit with 100-MHz CPU speed to provide six times higher performance for real-time measurement and control than existing high-temperature solutions. Other features include 512 KB of embedded flash memory and 68 KB internal RAM, integrated control-oriented peripherals to enable high precision, six high-resolution PWM outputs at 150 ps, and a high-speed 16-channel 12-bit ADC.
