Product details
Overview
F280048CPMQR from Texas Instruments is a 100MHz C28x 32-bit real-time microcontroller with IEEE 754 FPU, CLA accelerator, 128KB flash, 100KB RAM, and integrated analog (3×12-bit ADCs, 7 PGAs, 7 CMPSS). It targets high-precision motor control and power conversion in EV charging, solar inverters, and industrial drives.
For engineers reviewing the F280048CPMQR datasheet, F280048CPMQR pinout, F280048CPMQR application, or F280048CPMQR equivalent, key selection factors include functional safety compliance (ASIL B), 64-pin LQFP package, InstaSPIN-FOC™ ROM support, CLA offloading capability, and dual-zone security for third-party firmware development.
Technical Context
The F280048CPMQR implements a dual-core real-time control architecture: the 100MHz C28x CPU executes main control loops while the independent 100MHz CLA handles time-critical tasks like PWM update, current loop computation, and sensorless FOC. Both cores share access to ECC-protected memory and peripherals including ePWM (16 channels, 150ps resolution), SDFM (2 channels), and CAN (2 ports).
Its analog subsystem integrates three 3.45MSPS 12-bit ADCs with four post-processing blocks each, seven programmable-gain amplifiers (gain settings: 3/6/12/24), and seven windowed comparators with 12-bit DAC references - enabling closed-loop control with sub-microsecond latency and hardware trip-zone response.
