Product details
Overview
TMS320F280049PZS from Texas Instruments is a 100MHz C28x real-time MCU with IEEE 754 FPU, CLA accelerator, 256KB ECC-protected flash, 100KB RAM, and integrated analog subsystem including three 3.45MSPS 12-bit ADCs - deployed in solar inverters, EV charging power modules, and industrial motor drives.
For engineers reviewing the TMS320F280049PZS datasheet, TMS320F280049PZS pinout, TMS320F280049PZS application, or TMS320F280049PZS equivalent, key selection criteria include functional safety compliance (ASIL B), 16-channel ePWM with 150ps resolution, InstaSPIN-FOC™ ROM support, and 100-pin LQFP package thermal performance for high-power control systems.
Technical Context
The TMS320F280049PZS implements a dual-core real-time architecture: the 100MHz C28x CPU executes main control loops while the independent 100MHz CLA handles time-critical tasks like Park/Clarke transforms and PWM update timing. Its analog front end integrates seven PGAs (gain 3/6/12/24), seven CMPSS with 12-bit DAC references, and four SDFM channels for sigma-delta modulator interfacing across isolation barriers.
System-level timing is managed via two zero-pin oscillators, windowed watchdog, missing-clock detection, and ERAD hardware debug. Communications include two CAN ports, two SPI, two SCI, I²C, LIN, PMBus, and FSI - all pin-bootable and muxed across 40 GPIOs in the 100-pin PZ package.

This specification is validated per TI's thermal resistance characteristics and supports continuous operation in high-ambient environments such as enclosed power converters and outdoor EV charging stations. The 100-pin LQFP package includes an exposed thermal pad to aid heat dissipation.
Does the TMS320F280049PZS include a hardware floating-point unit?
Yes, the TMS320F280049PZS integrates an IEEE 754 single-precision Floating-Point Unit (FPU) within its C28x CPU core. This enables native floating-point arithmetic for complex control algorithms-including Park/Clarke transforms, PID tuning, and observer-based estimators-without software emulation overhead. The FPU operates at the full 100MHz CPU frequency.
Is the TMS320F280049PZS pin-compatible with other F28004x variants in the 100-pin PZ package?
Yes, the TMS320F280049PZS shares identical pinout, electrical characteristics, and package dimensions with other 100-pin PZ variants including TMS320F280049C, TMS320F280041PZS, and TMS320F280045. All support the same GPIO multiplexing, power sequencing, and peripheral pin assignments-enabling hardware reuse across design iterations.
What analog peripherals are integrated into the TMS320F280049PZS?
The TMS320F280049PZS integrates three independent 12-bit ADCs (3.45MSPS), seven programmable gain amplifiers (PGA gain settings: 3/6/12/24), seven windowed comparators with integrated 12-bit DAC references, two buffered DAC outputs, and four SDFM input channels. These enable full analog signal chain consolidation-from sensor conditioning to high-speed sampling and fast-trip decision logic.
Does the TMS320F280049PZS support functional safety certification for automotive use?
No-the TMS320F280049PZS is not AEC-Q100 qualified or certified for ASIL B. It is an industrial-grade (S-temperature) device.
