Product details
Overview
TMS320F280049CPZQR from Texas Instruments is a functional-safety-compliant 32-bit real-time MCU with 100MHz C28x CPU, IEEE 754 FPU, CLA accelerator, 256KB ECC-protected flash, and 100KB RAM. It integrates three 3.45MSPS 12-bit ADCs, 16 ePWM channels (150ps resolution), seven PGAs, and dual CAN for high-precision motor control in EV charging power modules and solar inverters.
For engineers reviewing the TMS320F280049CPZQR datasheet, TMS320F280049CPZQR pinout, TMS320F280049CPZQR application, or TMS320F280049CPZQR equivalent, key selection criteria include ASIL B functional safety certification, 100-pin LQFP package with 40 GPIOs and 21 analog inputs, InstaSPIN-FOC™ ROM support, and hardware trip zones for fast fault response in closed-loop power conversion systems.
Technical Context
The TMS320F280049CPZQR implements a dual-core real-time architecture: the main C28x CPU executes at 100MHz with TMU/VCU-I acceleration for trigonometric and complex math, while the independent CLA runs parallel floating-point code at 100MHz with dedicated memory and peripheral access. Both cores share a unified bus architecture supporting deterministic interrupt latency.
Its analog subsystem features three synchronized 12-bit ADCs (3.45MSPS each), four post-processing blocks per ADC, seven windowed comparators with integrated 12-bit DAC references, and seven programmable-gain amplifiers (gain settings: 3/6/12/24). The control peripherals include 16 ePWM channels with hardware dead-band and trip-zone logic, two eQEP modules, and four SDFM input channels for sigma-delta sensor interfacing.

It includes safety manuals, FMEDA reports, and diagnostic software libraries to support system-level compliance in automotive and industrial safety applications. This certification applies specifically to the TMS320F280049CPZQR part number as listed in TI's SPRS945H functional safety table.
Does the TMS320F280049CPZQR support InstaSPIN-FOC™ out of the box?
Yes, the TMS320F280049CPZQR includes the InstaSPIN-FOC™ motor control library pre-programmed in on-chip ROM, accessible without external flash loading. This enables immediate sensorless FOC deployment for BLDC and PMSM motors, with FAST™ estimator for real-time rotor position and speed calculation - a feature exclusive to 'C'-suffix variants like the TMS320F280049CPZQR.
What package and pin count does the TMS320F280049CPZQR use?
The TMS320F280049CPZQR uses a 100-pin Low-profile Quad Flatpack (LQFP) with PZ suffix, measuring 14×14 mm with 0.5 mm pitch. It provides 40 GPIOs, 21 analog input channels, dual CAN, two eQEP modules, and full access to all integrated analog peripherals - matching the maximum peripheral count within the F28004x family.
How does the CLA accelerator in the TMS320F280049CPZQR improve real-time performance?
The CLA in the TMS320F280049CPZQR is an independent 32-bit floating-point math accelerator running at 100MHz, executing control tasks (e.g., PID loops, observer calculations) in parallel with the main C28x CPU. It accesses dedicated RAM and key peripherals directly, offloading up to 50% of CPU workload and ensuring jitter-free execution of time-critical routines - verified in TI's C2000Ware CLA examples for TMS320F280049CPZQR.
Can the TMS320F280049CPZQR replace the TMS320F280049C in existing designs?
Yes, the TMS320F280049CPZQR is pin-compatible and functionally identical to the TMS320F280049C, with the addition of functional safety certification and associated documentation. No PCB or schematic changes are required; however, safety-critical applications must integrate TI's safety manual, diagnostic firmware, and validation procedures to leverage the ASIL B qualification of the TMS320F280049CPZQR.
