Product details
Overview
TMS320F280045PZS from Texas Instruments is a 100MHz C28x-based real-time MCU with IEEE 754 FPU, CLA accelerator, 256KB flash (ECC-protected), 100KB RAM (ECC/parity-protected), and 40 GPIOs - designed for high-precision motor control in EV charging power modules and solar string inverters.
For engineers reviewing the TMS320F280045PZS datasheet, TMS320F280045PZS pinout, TMS320F280045PZS application, or TMS320F280045PZS equivalent, key selection criteria include 16-channel ePWM with 150ps resolution, three 3.45MSPS 12-bit ADCs, dual CAN interfaces, functional safety support up to ASIL B, and 100-pin LQFP (PZ) packaging for industrial thermal and layout stability.
Technical Context
The TMS320F280045PZS integrates a dual-core real-time control architecture: the main C28x CPU executes at 100MHz with FPU, TMU, and VCU-I for fast trigonometric and complex math, while the independent CLA runs parallel floating-point tasks at 100MHz with dedicated memory and peripheral access. Both cores share a unified bus architecture supporting deterministic low-latency response.
Its analog subsystem includes three synchronized 12-bit ADCs (3.45MSPS), seven PGAs (gain settings 3/6/12/24), seven CMPSS with integrated 12-bit DAC references, and four SDFM input channels - enabling simultaneous current/voltage sensing, overcurrent trip detection, and sigma-delta modulator interfacing across isolation barriers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F280049PZS | Includes Configurable Logic Block (CLB) and InstaSPIN-FOC™ ROM library; same 256KB flash, 100-pin PZ package. | Required for position manager implementations and sensorless FOC deployment without external code loading. | Select F280049PZS when CLB logic or pre-certified FOC library is needed; F280045PZS suffices for standard vector control with external algorithm implementation. |
| TMS320F280041PZS | 128KB flash, no CLB, no InstaSPIN-FOC™ ROM; identical CPU, CLA, analog, and PWM peripherals in same PZ package. | Suitable for cost-sensitive applications with smaller firmware footprints and no need for hardware-accelerated position logic. | Choose F280041PZS for entry-level solar microinverters or HVAC fan controllers where flash headroom and CLB are non-critical. |
Compared with TMS320F280049PZS, TMS320F280045PZS omits CLB and InstaSPIN-FOC™ but retains full analog/PWM/peripheral capability; versus TMS320F280041PZS, it doubles flash capacity and adds dual-zone security - making it optimal for mid-tier industrial power converters requiring firmware flexibility and functional safety readiness.

The TMS320F280045PZS features a C28x 32-bit CPU core rated for 100MHz operation under all recommended conditions. This frequency is sustained across the full –40°C to 125°C junction temperature range and supports deterministic real-time execution of control loops with sub-1µs interrupt latency. The CLA accelerator also operates concurrently at 100MHz, enabling true dual-core deterministic control.
Does the TMS320F280045PZS include hardware support for functional safety standards?
Yes, the TMS320F280045PZS is Functional Safety Quality-Managed (FS-QM) and supports system-level development targeting ISO 26262 ASIL B and IEC 61508 SIL 3. It includes hardware features such as ECC-protected memory, windowed watchdog timers, missing-clock detection, and dual-zone security - documented in TI's Functional Safety Manual SPRUIJ7 for TMS320F28004x devices.
How many analog-to-digital converters does the TMS320F280045PZS integrate, and what are their key specifications?
The TMS320F280045PZS integrates three independent 12-bit ADCs, each capable of 3.45MSPS sampling rate with 290ns conversion time. Each ADC supports up to 21 external input channels and includes four post-processing blocks (PPBs) for real-time filtering, averaging, and oversampling - enabling high-fidelity current/voltage measurement in multi-phase power converters.
What communication interfaces are available on the TMS320F280045PZS, and which support pin-bootable operation?
The TMS320F280045PZS provides two CAN 2.0B ports, two SPI interfaces, two UART-compatible SCIs, one I²C, one PMBus, one LIN, and one Fast Serial Interface (FSI). All CAN, I²C, SPI, SCI, and LIN interfaces are pin-bootable - allowing firmware initialization directly from external EEPROM or flash via those peripherals without requiring JTAG or external programmer.
What is the flash memory configuration of the TMS320F280045PZS, and how is error correction implemented?
The TMS320F280045PZS contains 256KB (128KW) of on-chip flash memory divided into two independent 128KB banks, each protected by SEC-DED ECC. This architecture enables concurrent read-execute and write-erase operations, critical for over-the-air firmware updates in field-deployed power systems while maintaining runtime integrity and preventing silent data corruption.
