Product details
Overview
TMS320F280049PMS from Texas Instruments is a 100MHz C28x-based real-time microcontroller with IEEE 754 FPU, CLA accelerator, 256KB ECC-protected flash, 100KB RAM, and integrated analog subsystem including three 3.45MSPS 12-bit ADCs-designed for high-precision motor control in EV charging power modules and solar string inverters.
For engineers reviewing the TMS320F280049PMS datasheet, TMS320F280049PMS pinout, TMS320F280049PMS application, or TMS320F280049PMS equivalent, key selection criteria include ePWM resolution (150ps), dual CAN interfaces, InstaSPIN-FOC™ ROM support, functional safety compliance (ASIL B), and 64-pin LQFP package compatibility with industrial temperature range (–40°C to 125°C).
Technical Context
The TMS320F280049PMS implements a dual-core real-time control architecture: the 100MHz C28x CPU executes main control loops with TMU/VCU-I acceleration for trigonometric and complex math, while the independent 100MHz CLA offloads time-critical tasks like PWM update and current loop computation. Both cores share access to dual-bank flash and ECC-protected RAM.
Its analog subsystem integrates three synchronized 12-bit ADCs (3.45MSPS), seven PGAs (gain 3/6/12/24), seven windowed comparators with 12-bit DAC references, and four SDFM input channels-enabling simultaneous high-fidelity current/voltage sensing and fast overcurrent trip response in isolated power stages.

FAQ
What is the maximum operating frequency of the TMS320F280049PMS CPU core?
The TMS320F280049PMS features a TMS320C28x 32-bit CPU core rated at 100MHz. This clock speed is fully supported across the specified industrial temperature range (–40°C to 125°C) and enables sub-microsecond interrupt latency for hard real-time control loops in motor and power conversion systems. The CLA accelerator also operates at 100MHz independently.
Does the TMS320F280049PMS support functional safety certification for automotive applications?
Yes, the TMS320F280049PMS is ISO 26262 certified up to ASIL B by TÜV SÜD. It includes hardware safety mechanisms such as ECC on flash and RAM, windowed watchdog timers, missing-clock detection, and ERAD debug support. Documentation-including the Functional Safety Manual-is provided to aid system-level ASIL D development in automotive on-board chargers and wireless charging modules.
How many analog-to-digital converter (ADC) channels does the TMS320F280049PMS support in the 64-pin LQFP package?
In the 64-pin LQFP (PM) package, the TMS320F280049PMS supports 14 single-ended ADC input channels. These are distributed across its three integrated 12-bit, 3.45MSPS ADCs and include dedicated pins for PGA inputs and analog reference voltages. Full 21-channel capability is available only in the 100-pin PZ variant.
Is InstaSPIN-FOC™ firmware included in the TMS320F280049PMS?
No-InstaSPIN-FOC™ is only available in the "C"-suffix variants (e.g., TMS320F280049C). The TMS320F280049PMS lacks the secure ROM containing the InstaSPIN library. However, it retains full hardware compatibility with InstaSPIN-enabled software tools and supports standard FOC implementation using C2000Ware libraries and the CLA for accelerated math operations.
What communication interfaces are available on the TMS320F280049PMS?
The TMS320F280049PMS provides 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 support multiplexing on shared GPIOs. The FSI enables high-speed isolated communication up to 100Mbps, ideal for gate driver feedback in SiC/GaN systems.
