STMicroelectronics STEVAL-IKM001V1

Overview

STEVAL-IKM001V1 from STMicroelectronics is an evaluation kit for the L6470H dSPIN microstepping motor driver IC, comprising EVAL6470H driver board, STEVAL-PCC009V2 communication interface board, and two L6470H + two L6470PD samples. It supports 8–45 V supply, up to 3 A_RMS phase current, SPI daisy-chaining, external resonator/crystal socket, SW input, FLAG/busy LED indicators, and adjustable supply voltage compensation.

For engineers reviewing the STEVAL-IKM001V1 datasheet, STEVAL-IKM001V1 pinout, STEVAL-IKM001V1 application, or STEVAL-IKM001V1 equivalent, this kit enables full functional validation of L6470H in voltage-mode stepper control, multi-motor daisy-chain configuration, parameter tuning via dSPIN GUI, and real-time motor behavior analysis under variable load and speed profiles.

Technical Context

The kit implements a complete hardware-software evaluation environment centered on the L6470H - a fully integrated motion controller and driver with embedded 32-bit position/velocity/acceleration registers, non-volatile parameter storage, and adaptive thermal management. It interfaces via SPI at up to 5 MHz and supports both standalone (SW input) and host-controlled operation.

EVAL6470H provides direct access to all L6470H control signals including STEP/DIR, BUSY, FLAG, and RESET; the STEVAL-PCC009V2 bridges USB 2.0 to SPI using an STM32F103-based bridge MCU and includes on-board 3.3 V LDO regulation and level-shifting circuitry for robust host communication.

FAQ

What software is required to operate STEVAL-IKM001V1?

The kit requires ST's official dSPIN Evaluation Software (v3.x), a Windows-based GUI that communicates over USB to configure L6470H registers, generate motion profiles, monitor real-time status (BUSY/FLAG), and log motor behavior. No custom driver installation is needed - the STEVAL-PCC009V2 enumerates as a standard CDC ACM device.

Can STEVAL-IKM001V1 evaluate both L6470H and L6470PD devices?

Yes - the EVAL6470H board is mechanically and electrically compatible with both L6470H (HTSSOP28 package) and L6470PD (PowerSO-36 package). The kit includes two samples of each variant, and the dSPIN software automatically detects device type and adjusts register mapping accordingly.

Does the kit support real-time current measurement?

No - the EVAL6470H does not include shunt resistors or ADC circuitry for analog current sensing. Current limiting is set digitally via the L6470H's KVAL parameters and validated indirectly through thermal monitoring (THERMAL_SHUTDOWN flag) and motor stall detection (FLAG output).

Is external power required for the motor supply?

Yes - the kit requires an external 8–45 V DC power source connected to the EVAL6470H VIN terminals. The STEVAL-PCC009V2 draws only 5 V USB power and does not supply motor voltage; isolation between logic and motor domains is maintained via optocoupled SPI lines and separate ground planes.
