Product details
Overview
F280049CPMS from Texas Instruments is a 32-bit real-time microcontroller (MCU) with dual 100MHz C28x CPU and CLA cores, IEEE 754 FPU, TMU/VCU-I math accelerators, 256KB ECC-protected flash, 100KB RAM, and integrated analog peripherals including three 3.45MSPS 12-bit ADCs, seven PGAs, and 16 ePWM channels with 150ps resolution-designed for high-precision motor control in EV charging power modules.
For engineers reviewing the F280049CPMS datasheet, F280049CPMS pinout, F280049CPMS application, or F280049CPMS equivalent, this page delivers verified technical context, package-specific pin roles, functional safety compliance (ASIL B), InstaSPIN-FOC™ ROM support, and validated alternatives for industrial power conversion and motor drive designs.
Technical Context
The F280049CPMS implements a dual-core real-time control architecture: the main C28x CPU executes deterministic control loops at 100MHz with hardware-accelerated trigonometric (TMU) and complex math (VCU-I) operations, while the independent CLA core runs parallel floating-point tasks-including PWM update, ADC post-processing, and observer calculations-at 100MHz without CPU intervention.
Its analog subsystem integrates three synchronized 12-bit ADCs (3.45MSPS), seven programmable-gain amplifiers (gain settings: 3/6/12/24), seven windowed comparators with 12-bit DAC references, and four SDFM input channels-enabling simultaneous current/voltage sensing, fast overcurrent trip response, and sigma-delta modulator interfacing across isolation barriers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time motor control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F280041CPMS | 128KB flash, no CLB, no InstaSPIN-FOC™ ROM, same 64-pin PM package and peripheral set | Lacks on-chip FOC library and CLB logic; suitable for cost-sensitive, non-sensorless applications with simpler control requirements | Select when full 256KB flash and hardware-accelerated FOC are not required; retains identical pinout and layout compatibility |
| TMS320F280049CPTQ | 100-pin LQFP (PZ), adds 15 more GPIOs and 7 additional ADC channels vs. 64-pin variant | Enables higher channel-count systems (e.g., multi-motor drives, modular PCS) but requires PCB redesign | Choose for expanded I/O and analog channel needs; not pin-compatible-requires new layout and signal routing |
Compared with F280049CPMS, F280041CPMS reduces flash and removes CLB/FOC for lower cost in fixed-function drives, while F280049CPTQ trades compactness for scalability in multi-axis or high-channel-count energy systems.

FAQ
What is the maximum ADC sampling rate supported by the F280049CPMS?
The F280049CPMS supports three independent 12-bit ADCs each operating at up to 3.45 million samples per second (MSPS), with conversion time of 290ns. All three ADCs can be synchronized for simultaneous sampling across multiple current/voltage channels-critical for vector control in motor drives and power converters where phase alignment affects accuracy.
Does the F280049CPMS include hardware support for functional safety certification?
Yes, the F280049CPMS is ISO 26262-certified up to ASIL B by TÜV SÜD and provides hardware integrity features including ECC-protected memory, parity/ECC SRAM, windowed watchdog timers, missing-clock detection, and hardware trip zones. It supports systematic development up to ASIL D with documentation available for safety-critical system integration.
How many ePWM channels does the F280049CPMS provide, and what is their timing resolution?
The F280049CPMS provides 16 ePWM channels with high-resolution capability down to 150 picoseconds. This ultra-fine resolution enables precise dead-time insertion, phase-shift control in resonant converters, and accurate duty-cycle modulation for high-frequency GaN/SiC switching-directly improving efficiency and EMI performance in modern power stages.
Is InstaSPIN-FOC™ firmware included in the F280049CPMS?
Yes, the F280049CPMS includes the InstaSPIN-FOC™ library pre-programmed in on-chip ROM. This enables rapid sensorless field-oriented control of BLDC and PMSM motors without external code loading-reducing development time and eliminating dependency on host processor resources during motor commissioning and runtime operation.
What communication interfaces are available on the F280049CPMS?
The F280049CPMS integrates two CAN 2.0B ports, one PMBus interface, one I²C port, two UART-compatible SCIs, two SPI ports, one LIN interface, one Fast Serial Interface (FSI), and one USB-capable interface. These support robust, multi-protocol communication for system-level coordination in EV chargers, inverters, and industrial drives-especially FSI for high-speed isolated data transfer.
