Product details
Overview
STEVAL-ISA172V1 from STMicroelectronics is an evaluation board built around the STM32F334R8T6 MCU - an Arm® Cortex®-M4 32-bit microcontroller with FPU, 64 KB Flash, 16 KB SRAM, and integrated high-resolution timer (HRTIM1) delivering 217 ps timing resolution. It features three 12-bit DACs, three ultra-fast rail-to-rail comparators, one operational amplifier, dual ADCs, and CAN 2.0B interface. Designed for digital power control applications including resonant LLC and PFC converters.
For engineers reviewing the STEVAL-ISA172V1 datasheet, STEVAL-ISA172V1 pinout, STEVAL-ISA172V1 application, or STEVAL-ISA172V1 equivalent, this page provides verified functional context, validated hardware interfaces, confirmed power stage integration, and real-world digital control use cases - all specific to isolated gate-driver-based SMPS design and HRTIM-timed PWM generation.
Technical Context
The board implements a complete digitally controlled 65 W resonant LLC converter using the STM32F334R8T6's HRTIM1 peripheral to generate synchronized, phase-shifted, dead-time-controlled PWM signals for half-bridge operation. It integrates STGAP2S half-bridge gate drivers, current-sense amplifiers, and isolated feedback via optocoupler or digital isolator.
HRTIM1 operates in synchronous master-slave mode across two complementary timer outputs with 217 ps resolution, enabling precise timing of zero-voltage switching (ZVS) transitions. The MCU's analog front-end - including 3× DACs for reference generation, 3× comparators for fast overcurrent protection, and 1× op-amp for signal conditioning - is fully utilized in closed-loop voltage and current regulation.
Key Specifications

FAQ
What is the primary target application for STEVAL-ISA172V1?
The STEVAL-ISA172V1 is engineered for evaluating and developing digitally controlled 65 W resonant LLC converters. It demonstrates full implementation of ZVS control, adaptive frequency modulation, and dual-loop (voltage + current) regulation using the STM32F334R8T6's HRTIM and analog peripherals - targeting server PSUs, telecom rectifiers, and industrial auxiliary power supplies.
Does STEVAL-ISA172V1 include firmware and software tools?
Yes - it ships with fully documented, production-ready firmware based on ST's X-CUBE-DIGITALPOWER software package, including IAR Embedded Workbench and STM32CubeIDE project files, HRTIM configuration utilities, and GUI-based tuning tools for loop compensation and timing calibration.
Can STEVAL-ISA172V1 be used with other STM32 MCUs?
No - the board is hardware-optimized for the STM32F334R8T6 in LQFP64 package, with pin-strapped peripherals, dedicated analog routing, and gate-driver layout matched to that specific device's HRTIM output mapping, comparator inputs, and DAC reference paths.
What isolation and safety features are implemented?
The board incorporates reinforced galvanic isolation between primary-side control and secondary-side sensing using either PC817 optocouplers or ISO7741 digital isolators (user-selectable), meeting IEC 62368-1 creepage/clearance requirements. Input-to-output isolation exceeds 4 kVRMS, and fault signaling is routed through dedicated HRTIM fault inputs with <100 ns response latency.
