Product details
Overview
TMS320F280049CPZS from Texas Instruments is a 100MHz C28x-based real-time MCU with IEEE 754 FPU, CLA, and 256KB flash, designed for high-precision motor control and power conversion systems requiring deterministic timing, analog signal conditioning, and functional safety support up to ASIL B.
For engineers reviewing the TMS320F280049CPZS datasheet, TMS320F280049CPZS pinout, TMS320F280049CPZS application, or TMS320F280049CPZS equivalent, this page delivers verified specifications, package-specific GPIO mapping, CLA/CLA-independent execution context, InstaSPIN-FOC™ ROM integration, and functional safety documentation alignment per ISO 26262.
Technical Context
The TMS320F280049CPZS implements a dual-core real-time control architecture: the 100MHz C28x CPU handles main-loop scheduling and system management, while the independent 100MHz CLA executes time-critical control algorithms-including Park/Clarke transforms and PWM update logic-without CPU intervention. Both cores share access to ECC-protected 256KB flash and 100KB RAM, with dual-zone security enabling third-party firmware partitioning.
Analog subsystem integration includes three 3.45MSPS 12-bit ADCs (21 external channels), seven PGA inputs (gain 3/6/12/24), seven windowed comparators with 12-bit DAC references, and four SDFM input channels-enabling simultaneous high-resolution current sensing, voltage monitoring, and sigma-delta modulator interfacing across isolation barriers.

FAQ
What is the maximum operating frequency of the TMS320F280049CPZS CPU and CLA?
The TMS320F280049CPZS features a TMS320C28x CPU and a Control Law Accelerator (CLA) both rated at 100MHz. This dual 100MHz architecture enables parallel execution of main-loop control and time-critical tasks such as PWM update, current loop calculation, and fault response-ensuring deterministic sub-microsecond latency in real-time motor and power control applications. The TMS320F280049CPZS maintains this performance across its full –40°C to 125°C junction temperature range.
Does the TMS320F280049CPZS include InstaSPIN-FOC™ software in ROM?
Yes, the TMS320F280049CPZS includes the InstaSPIN-FOC™ motor control library pre-programmed in on-chip ROM. This enables immediate deployment of sensorless field-oriented control for PMSM and induction motors without external flash or host processor dependency. The TMS320F280049CPZS leverages its integrated FPU, CLA, and FAST™ estimator to execute rotor position estimation and torque control entirely on-chip, reducing BOM cost and development time.
What analog peripherals are integrated into the TMS320F280049CPZS?
The TMS320F280049CPZS integrates three independent 12-bit ADCs operating at 3.45MSPS with up to 21 external input channels, seven programmable gain amplifiers (PGAs) with selectable gains of 3/6/12/24, seven windowed comparators (CMPSS) each with a 12-bit reference DAC, two buffered DAC outputs, and four Sigma-Delta Filter Module (SDFM) input channels. These peripherals support simultaneous high-fidelity current/voltage sensing, fast overcurrent protection, and isolated sigma-delta modulator interfacing-all without external signal conditioning components.
Is the TMS320F280049CPZS pin-compatible with other F28004x devices?
The TMS320F280049CPZS is pin-compatible with other 100-pin PZ-package F28004x variants (e.g., TMS320F280049C, TMS320F280049C-Q1) but not with 64-pin PM or 56-pin RSH variants due to differing pin counts and peripheral mappings. Within the PZ package family, all devices share identical pin assignments, power sequencing, and GPIO functionality-allowing hardware reuse across commercial, automotive, and functional-safety versions when software and qualification requirements align.
What functional safety certifications apply to the TMS320F280049CPZS?
The TMS320F280049CPZS is Functional Safety Quality-Managed (FS-QM) and supports system-level ISO 26262 ASIL B and IEC 61508 SIL 3 development. While not itself ISO 26262-certified (that status applies to the automotive-grade TMS320F280049C-Q1), the TMS320F280049CPZS provides the same hardware safety mechanisms-including ECC memory, windowed watchdog, ERAD debug, and hardware trip zones-as its Q1 counterpart, enabling compliant system design with appropriate documentation and analysis.
