Product details
Overview
STEVAL-ISA172V2 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, 217 ps high-resolution timer (HRTIM), 3 DACs, and integrated op-amp - designed for digital power control applications including LLC resonant converters and motor gate drivers.
For engineers reviewing the STEVAL-ISA172V2 datasheet, STEVAL-ISA172V2 pinout, STEVAL-ISA172V2 application, or STEVAL-ISA172V2 equivalent, this board provides validated hardware reference for HRTIM-based PWM generation, analog signal conditioning, and real-time digital power loop implementation using STM32's embedded analog peripherals and ultra-precise timing.
Technical Context
The STEVAL-ISA172V2 implements a complete isolated digital power controller reference design, centered on the STM32F334R8T6's HRTIM peripheral delivering 217 ps resolution across six 16-bit counters and ten complementary PWM outputs with fault protection, synchronized external event handling, and deadtime insertion - enabling precise phase-shifted and interleaved topologies.
It integrates analog signal chain components including three 12-bit DACs (2.4–3.6 V supply), one rail-to-rail operational amplifier (configurable as PGA), three ultra-fast comparators, and dual 12-bit ADCs (0.2 µs conversion, 12/10/8/6-bit selectable resolution) - all referenced to a dedicated 2.0–3.6 V analog supply domain for noise-immune feedback sensing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core | Arm® Cortex®-M4 with FPU, 72 MHz max clock - enables real-time digital control loops with floating-point math acceleration. |
| Flash / SRAM | 64 KB Flash + 16 KB SRAM - sufficient for complex power algorithms, firmware updates, and runtime data logging. |
| HRTIM Resolution | 217 ps timing resolution - supports sub-nanosecond PWM edge placement critical for soft-switching in resonant converters. |
| Analog Peripherals | 2 × 12-bit ADCs (0.2 µs), 3 × 12-bit DACs, 3 × comparators, 1 × op-amp - forms full analog front-end for voltage/current sensing and reference generation. |
| Package | LQFP64 (10 × 10 mm) - standard surface-mount footprint compatible with industrial PCB assembly and thermal management. |
| Power Supply Range | VDD: 2.0–3.6 V; VDDA: 2.0–3.6 V - ensures stable analog performance across wide input voltage variations in power supplies. |

FAQ
What is the primary target application for the STEVAL-ISA172V2?
The STEVAL-ISA172V2 is purpose-built for evaluating and developing digital power control systems - especially LLC resonant converters and synchronous rectification controllers - leveraging the STM32F334R8T6's 217 ps HRTIM, integrated op-amp, and multi-channel DAC/ADC for closed-loop regulation without external signal conditioning ICs.
Does the board support isolation between control and power stages?
Yes - the STEVAL-ISA172V2 features galvanic isolation via ADuM4135 dual-channel isolated gate drivers and ADuM1401 digital isolators, separating the STM32F334R8T6 control domain from the high-voltage power stage while maintaining precise timing synchronization and fault reporting paths.
Can the HRTIM outputs be used for phase-shifted or interleaved PWM generation?
Yes - the HRTIM peripheral on the STM32F334R8T6 supports six independent 16-bit timers with cross-triggering, synchronization inputs/outputs, and programmable deadtime, enabling robust implementation of phase-shifted full-bridge, interleaved multi-phase, and asymmetrical PWM topologies directly in hardware.
Is firmware and software support provided with the board?
Yes - ST provides the X-CUBE-DIGITALPOWER software package, including HAL drivers, HRTIM configuration utilities, digital compensator libraries (PID, PR), and ready-to-run examples for LLC control, all compatible with STM32CubeMX and STM32CubeIDE - no additional license required.
