Product details

Overview

STEVAL-ILL077V1 from STMicroelectronics is a ready-to-use evaluation board for the STNRG388A digital controller, designed to accelerate development of high-efficiency LED drivers and AC-DC power supplies with digital control. It integrates the TSSOP38-packaged STNRG388A MCU featuring 6 SMED-based PWM generators (10 ns event response, 1.3 ns resolution), 4 analog comparators (<50 ns propagation), 10-bit ADC (extendable to 12-bit equivalent), 96 MHz PLL, and -40 °C to 105 °C operation.

For engineers reviewing the STEVAL-ILL077V1 datasheet, STEVAL-ILL077V1 pinout, STEVAL-ILL077V1 application, or STEVAL-ILL077V1 equivalent, this page delivers verified technical context, key specifications, supply readiness, manufacturer background, and targeted FAQs - all focused on rapid prototyping of digitally controlled LED lighting systems and isolated flyback/buck-boost converters.

Technical Context

The STEVAL-ILL077V1 implements a complete digital LED driver reference design centered on the STNRG388A, which combines an STM8® core (16 MHz max CPU) with dedicated hardware accelerators: six State Machine Event Driven (SMED) PWM units supporting single/coupled modes, four ultra-fast analog comparators with configurable hysteresis, and a sequencer-enabled 10-bit ADC with programmable gain (x1/x4) and op-amp front-end.

It leverages the STNRG388A's integrated clock system-including a 96 MHz PLL, trimmable 16 MHz RC oscillator, and 153.6 kHz low-power RC-alongside dual communication interfaces (UART with bootloader support and I²C master/slave) to enable real-time firmware updates, telemetry, and DALI-compliant lighting control without external timing components.

Key Specifications

Parameter	Value and Actual Design Meaning
Core Architecture	STM8® 8-bit Harvard core with 3-stage pipeline; enables deterministic real-time control loops at 16 MHz CPU frequency.
PWM Generation	6 independent SMED units; supports <1.3 ns resolution and <10 ns event reaction for precise phase-shifted or interleaved LED current regulation.
Analog Comparators	4 units with <50 ns propagation delay and user-configurable hysteresis; used for fast overvoltage/overcurrent protection in primary-side sensing.
ADC System	10-bit SAR ADC with op-amp gain (x1/x4); achieves effective 12-bit resolution for accurate LED string voltage/current feedback sampling.
Clock Sources	Internal 96 MHz PLL + 16 MHz RC (user-trimmable) + 153.6 kHz LP RC; eliminates need for external crystal while maintaining tight timing accuracy for PWM synchronization.
Memory Resources	32 KB Flash (RWW + ECC), 1 KB true EEPROM (100 kcycles @ 85 °C), 6 KB RAM; supports field firmware updates and persistent configuration storage.
Operating Range	-40 °C to +105 °C ambient; validated for industrial-grade LED driver deployments in enclosed luminaires and outdoor signage.

FAQ

What is the primary function of the STEVAL-ILL077V1 evaluation board?

The STEVAL-ILL077V1 is a fully assembled and tested evaluation platform for the STNRG388A digital controller, preconfigured to demonstrate high-efficiency, digitally controlled LED driver operation using primary-side regulation. It includes onboard EMI filtering, gate drivers, current-sense circuitry, and DALI interface support - enabling immediate validation of closed-loop dimming, thermal derating, and fault response without custom PCB design.

Does STEVAL-ILL077V1 support firmware reprogramming in-system?

Yes - the board provides SWIM (Single Wire Interface Module) debug access via ST-LINK/V2-1 and supports UART-based bootloader updates. The STNRG388A's Read-While-Write Flash and ECC-protected memory allow safe field firmware upgrades without interrupting power delivery, and the included STSW-STM32117 software package provides configuration tools and example projects.

Can STEVAL-ILL077V1 be used for non-LED power conversion applications?

Yes - while optimized for LED drivers, the underlying STNRG388A controller supports generic digital power topologies including flyback, buck-boost, and LLC resonant converters. The board's flexible GPIO mapping, configurable SMED PWM outputs, and analog input routing allow adaptation to other constant-voltage or constant-current power supply designs with appropriate external component changes.

What documentation and software tools accompany STEVAL-ILL077V1?

STMicroelectronics provides the full STNRG388A datasheet (DocID027799), the STEVAL-ILL077V1 user manual (UM2524), schematic and layout files, BOM, and the STSW-STM32117 firmware development suite. This includes SMED configuration utilities, ADC calibration scripts, and pre-validated DALI stack libraries compatible with STM8CubeMX and STVD IDE.
