Product details
Overview
HLG031PAGT from Texas Instruments is a 64-pin TQFP-packaged C2000™ real-time microcontroller featuring a 60MHz TMS320C28x CPU, programmable Control Law Accelerator (CLA), 32KB on-chip Flash, 10KB SARAM, and integrated high-resolution PWM, eCAP, eQEP, 12-bit ADC (4.6 MSPS), comparators with DACs, eCAN, LIN, I²C, SPI, and SCI peripherals - deployed in EV charging power modules and solar string inverters.
For engineers reviewing the HLG031PAGT datasheet, HLG031PAGT pinout, HLG031PAGT application, or HLG031PAGT equivalent, this page delivers verified technical context, package-validated pin functions, real-world use cases in power conversion control, and confirmed alternative parts for design continuity and supply resilience.
Technical Context
The HLG031PAGT implements a Harvard-architecture 32-bit C28x CPU with atomic operations and fast interrupt response, paired with a dedicated CLA that executes floating-point control law code independently of the main CPU - enabling deterministic sub-microsecond loop closure in motor and power converter applications. Its memory subsystem includes 32KB Flash (secure, OTP-wrapped), 10KB zero-wait-state SARAM, and 8KB boot ROM.
Peripheral integration centers on real-time actuation: 12 ePWM channels (7 with high-resolution capability), 1 eQEP module, 1 eCAP input, 16-channel 12-bit ADC with dual sample-and-hold and 216.67 ns conversion time, three analog comparators with integrated 10-bit DACs, and full CAN 2.0B-compliant eCAN plus LIN, I²C, dual SPI, and SCI interfaces - all accessible via 33 multiplexed GPIO pins.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMS320F28034PAGT | Same 64-pin TQFP package; 32KB Flash, 10KB SARAM, but no CLA accelerator | Lacks hardware-accelerated floating-point control law execution; suitable for simpler scalar control or cost-sensitive designs | Select when CLA is not required and BOM cost reduction is prioritized over advanced loop performance |
| TMS320F28035PAGT | Same 64-pin TQFP package; 64KB Flash, 10KB SARAM, includes CLA (same as HLG031PAGT) | Double Flash capacity enables larger control algorithms, bootloader + application separation, or dual-image OTA updates | Select when field-upgradable firmware, complex observer-based control, or extended diagnostics require >32KB code space |
Compared with HLG031PAGT, TMS320F28034PAGT removes CLA capability for cost savings while retaining identical peripheral count and timing specs, whereas TMS320F28035PAGT doubles Flash without altering CLA or analog/peripheral features - offering direct scalability for algorithm complexity or firmware robustness.

FAQ
What is the maximum operating temperature range for HLG031PAGT?
HLG031PAGT is rated for operation from –40°C to 105°C (industrial temperature grade, denoted by 'T' suffix). It does not carry automotive AEC-Q100 qualification; for automotive applications, the pin-compatible HLG031PAGT-Q1 variant must be used.
Does HLG031PAGT include a hardware cryptographic engine?
No, HLG031PAGT does not include a hardware cryptographic engine. Its security features are limited to the Code Security Module with 128-bit key lock, which protects Flash, SARAM, and OTP memory blocks from unauthorized read/write access - but it provides no AES, SHA, or TRNG acceleration.
How many high-resolution PWM channels does HLG031PAGT support?
HLG031PAGT supports 7 high-resolution ePWM channels. These channels enable dual-edge modulation with sub-nanosecond timing resolution, critical for soft-switching topologies like LLC resonant converters and SiC/GaN gate driving in high-frequency power stages.
Can HLG031PAGT operate from a single 3.3-V supply without external regulators?
Yes, HLG031PAGT integrates an internal voltage regulator (VREG) and requires only a single 3.3-V supply. No power sequencing is needed, and the device includes built-in power-on reset (POR) and brown-out reset (BOR) circuitry - simplifying board-level power design.
Is the CLA in HLG031PAGT compatible with existing C28x assembly code?
No, the CLA in HLG031PAGT is a separate 32-bit floating-point accelerator with its own instruction set and memory map. While the main C28x CPU runs legacy C28x assembly/C code, CLA code must be written in C or assembly specific to the CLA architecture and linked via TI's C2000 compiler toolchain.
