Texas Instruments F280039PZRQ1

Overview

F280039PZRQ1 from Texas Instruments is a C2000™ real-time microcontroller featuring a 120-MHz TMS320C28x DSP core with IEEE 754 FPU, 384KB ECC-protected flash across three banks, 69KB ECC-protected RAM, and dual-zone security. It integrates 16 ePWM channels (8 with 150-ps high-resolution), three 4-MSPS 12-bit ADCs, and functional safety compliance up to ASIL B/SIL 2 for automotive powertrain control in inverters and motor drives.

For engineers reviewing the F280039PZRQ1 datasheet, F280039PZRQ1 pinout, F280039PZRQ1 application, or F280039PZRQ1 equivalent, key selection criteria include its 100-pin LQFP package, AEC-Q100 qualification, integrated CLA and CLB for deterministic control loop offload, CAN FD + DCAN dual-bus support, and Live Firmware Update capability for zero-downtime field updates.

Technical Context

The F280039PZRQ1 implements a dual-core real-time architecture: the 120-MHz C28x CPU executes main control firmware with FPU/TMU/VCRC acceleration, while the independent 120-MHz CLA handles time-critical tasks like PWM update, ADC post-processing, and PID loops without CPU intervention. Its memory subsystem includes three isolated flash banks enabling concurrent execute-and-program operations.

Peripherals are tightly coupled for minimal latency: ePWM modules feature hardware trip zones and dead-band generation; ADCs feed directly into Post-Processing Blocks and CMPSS comparators with 12-bit DAC references; and the Fast Serial Interface (FSI) provides 200 Mbps isolated communication. The Configurable Logic Block (CLB) adds four programmable tiles for custom logic interfacing with position sensors or encoder protocols.

FAQ

What is the maximum junction temperature rating for the F280039PZRQ1?

The F280039PZRQ1 is rated for a junction temperature range of –40°C to 150°C, validated per AEC-Q100 Grade 0 requirements. This allows operation in under-hood automotive environments and high-power-density industrial inverters where thermal margins are constrained. The device includes on-die temperature sensor and thermal shutdown circuitry that triggers at 155°C to protect against sustained overtemperature conditions. Thermal resistance for the 100-pin PZ package is 22.5°C/W (junction-to-case).

Does the F280039PZRQ1 support both CAN 2.0 and CAN FD simultaneously?

Yes, the F280039PZRQ1 integrates two independent CAN controllers: one DCAN module compliant with CAN 2.0B (up to 1 Mbps) and one MCAN module supporting CAN FD (up to 5 Mbps data rate). They operate concurrently with separate message RAM, filtering, and interrupt vectors. This enables simultaneous use-for example, DCAN for legacy diagnostics and MCAN for high-speed actuator control-without resource contention or software arbitration overhead in the F280039PZRQ1.

How does the Live Firmware Update (LFU) feature work on the F280039PZRQ1?

The F280039PZRQ1 implements hardware-accelerated Live Firmware Update using its three independent flash banks. During an update, new firmware is written to a standby bank while the active bank continues execution. A single register write triggers atomic bank swap with guaranteed sub-50-µs context switch, preserving all CPU registers and peripheral states. No external memory or bootloader code is required-the F280039PZRQ1's ROM bootloader validates signatures and manages bank state transitions securely.

What analog peripherals are included in the F280039PZRQ1 and how are they synchronized?

The F280039PZRQ1 integrates three 12-bit, 4-MSPS ADCs with 250-ns conversion time, four windowed comparators (CMPSS) with integrated 12-bit DAC references, two buffered DAC outputs, and eight Sigma-Delta Filter Module (SDFM) input channels. All three ADCs can be triggered synchronously via ePWM or software, enabling simultaneous sampling of phase currents and DC-link voltage. ADC results feed directly into Post-Processing Blocks for hardware-based averaging, offset correction, and oversampling-reducing CPU load and jitter in F280039PZRQ1-based motor control systems.

Is the Configurable Logic Block (CLB) on the F280039PZRQ1 compatible with Xilinx or Intel FPGA toolchains?

No, the CLB on the F280039PZRQ1 is not compatible with Xilinx or Intel FPGA toolchains. It uses TI's proprietary CLB Configuration Tool within C2000Ware and Code Generation Tools, generating bitstream files loaded into dedicated CLB configuration RAM at boot. Each of the four CLB tiles contains lookup tables, flip-flops, and interconnect resources optimized for real-time control logic-not general-purpose computation. Design entry is via schematic capture or Verilog-like behavioral description, compiled specifically for the F280039PZRQ1's CLB architecture.
