Product details
Overview
TMS320F280049PZSR from Texas Instruments is a 100MHz C28x 32-bit floating-point real-time microcontroller with IEEE 754 FPU, Trigonometric Math Unit (TMU), and 100MHz Control Law Accelerator (CLA). It integrates 256KB ECC-protected flash, 100KB RAM, three 3.45MSPS 12-bit ADCs, and 16 ePWM channels with 150ps resolution-designed for high-precision motor control in EV charging power modules and solar string inverters.
For engineers reviewing the TMS320F280049PZSR datasheet, TMS320F280049PZSR pinout, TMS320F280049PZSR application, or TMS320F280049PZSR equivalent, key selection factors include functional safety compliance (ASIL B certified), CLA offloading capability, 100-pin LQFP package with 40 GPIOs and 21 analog inputs, and InstaSPIN-FOC™ ROM support for sensorless field-oriented control.
Technical Context
The TMS320F280049PZSR implements a dual-core real-time control architecture: the main C28x CPU executes at 100MHz with FPU, TMU, and VCU-I acceleration for fast trigonometric and complex math; the independent CLA runs parallel 100MHz floating-point code to offload PWM timing-critical loops. Both cores share access to dual-bank flash and ECC-protected RAM.
Its analog subsystem includes three synchronized 12-bit ADCs (3.45MSPS), seven PGAs (gain 3/6/12/24), seven windowed comparators with integrated 12-bit DACs, and four SDFM input channels-enabling simultaneous current/voltage sensing and fast overcurrent trip response in isolated power stages.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F280049C | Same core, flash, and peripherals; includes Configurable Logic Block (CLB) and InstaSPIN-FOC™ ROM | Required for position manager implementations and sensorless FOC deployment without external libraries | Select TMS320F280049C if CLB or InstaSPIN-FOC™ functionality is needed; TMS320F280049PZSR lacks CLB and secure ROM features |
| TMS320F280048C-Q1 | Automotive-qualified (AEC Q100 Grade 1), same 100-pin PZ package, but 128KB flash and no CLB | Targeted for automotive traction inverters and onboard chargers requiring AEC Q100 qualification | Choose TMS320F280048C-Q1 only when AEC Q100 qualification is mandatory; TMS320F280049PZSR is industrial temperature grade (–40°C to 125°C) |
Compared with TMS320F280049C and TMS320F280048C-Q1, the TMS320F280049PZSR offers full industrial-feature set (256KB flash, 100MHz CLA, 3 ADCs) without CLB or automotive qualification-making it optimal for cost-sensitive, non-automotive high-performance power conversion where functional safety ASIL B suffices.

FAQ
What is the operating temperature range for the TMS320F280049PZSR?
The TMS320F280049PZSR is rated for industrial temperature operation from –40°C to 125°C junction temperature. This range supports deployment in demanding environments such as enclosed EV charging enclosures and outdoor solar inverters without derating. The device does not carry AEC Q100 automotive qualification, distinguishing it from Q1-suffixed variants like TMS320F280048C-Q1.
Does the TMS320F280049PZSR include the Configurable Logic Block (CLB)?
No, the TMS320F280049PZSR does not include the Configurable Logic Block (CLB). CLB is present only in 'C'-suffix variants such as TMS320F280049C and TMS320F280049C-Q1. The TMS320F280049PZSR shares the same CPU, CLA, memory, and analog/peripheral specifications but omits CLB tiles and the secure ROM containing InstaSPIN-FOC™.
What communication interfaces are supported by the TMS320F280049PZSR?
The TMS320F280049PZSR supports two CAN 2.0B ports, one PMBus interface, one I2C port, two SPI ports, two UART-compatible SCIs, one LIN interface, and one Fast Serial Interface (FSI). All are pin-bootable and fully muxed across its 100-pin LQFP package, enabling flexible system-level connectivity for power stage coordination, diagnostics, and grid communication.
Is the TMS320F280049PZSR certified for functional safety applications?
Yes, the TMS320F280049PZSR is Functional Safety Quality-Managed (FS-QM) and supports system-level ISO 26262 ASIL B and IEC 61508 SIL 3 development. While not itself ASIL B certified (certification applies to specific 'Q1' and 'C-Q1' variants), its hardware integrity, diagnostic coverage, and documentation align with ASIL B requirements when implemented per TI's Functional Safety Manual SPRUHZ6.
What is the ADC performance specification of the TMS320F280049PZSR?
The TMS320F280049PZSR integrates three independent 12-bit analog-to-digital converters, each capable of 3.45MSPS sampling rate with 290ns conversion time. It supports up to 21 external single-ended channels and includes four post-processing blocks per ADC for hardware-based averaging, filtering, and threshold comparison-critical for high-fidelity current sensing in multi-phase inverters.
