STMicroelectronics EVAL-L99DZ200

Overview

EVAL-L99DZ200 from STMicroelectronics is an automotive-grade evaluation board for the L99DZ200G front-door zone controller IC, integrating dual H-bridge motor drivers, LIN and CAN physical layers, heater/EC mirror control, reverse-battery protection, and real-time diagnostics via USB-connected GUI. It comprises a 150 mm × 120 mm motherboard (SPC582B60 MCU-based) and a 36.8 mm × 35.6 mm daughter board hosting the L99DZ200G.

For engineers reviewing the EVAL-L99DZ200 datasheet, EVAL-L99DZ200 pinout, EVAL-L99DZ200 application, or EVAL-L99DZ200 equivalent, this board enables rapid validation of front-door actuation, power trunk/tailgate control, rear door zone architecture, and multi-load automotive body electronics with configurable PWM, direction, and fault monitoring.

Technical Context

The EVAL-L99DZ200 implements a two-board architecture: the motherboard hosts the SPC582B60 32-bit Power Architecture MCU for system-level logic, LIN/CAN protocol handling, and GUI communication via FTDI USB bridge; the daughter board integrates the L99DZ200G device with four STL76N4F7AG MOSFETs per H-bridge, two STL19N3LLH6AG MOSFETs for heater/EC mirror loads, and STL64N4F7AG for reverse-battery protection.

It supports simultaneous control of up to 15 independent outputs (including high-side, low-side, and half-bridge configurations), real-time current/voltage monitoring, LIN 2.2A and CAN 2.0B physical layer compliance, and configurable diagnostic reporting via dedicated GUI software running on Windows XP–10.

FAQ

What microcontroller is used on the EVAL-L99DZ200 motherboard?

The motherboard uses the SPC582B60E1 32-bit Power Architecture MCU from STMicroelectronics, operating at up to 180 MHz with integrated LIN and CAN controllers, JTAG debug interface, and dedicated peripherals for driving the L99DZ200G daughter board via SPI and GPIO signals.

Does the EVAL-L99DZ200 support both LIN and CAN communication simultaneously?

Yes - the board integrates separate LIN transceivers (TJA1020-compatible) and CAN transceivers (TJA1042-compatible), enabling concurrent LIN-based local diagnostics and CAN-based vehicle network integration while maintaining electrical isolation between buses.

Can the EVAL-L99DZ200 be used to evaluate heater and electrochromic mirror functions?

Yes - the daughter board includes two dedicated STL19N3LLH6AG automotive-grade MOSFETs configured as high-side switches, supporting up to 30 A pulsed current for resistive heater elements and EC mirror glass control with programmable PWM dimming and thermal foldback via MCU supervision.

Is USB connection required to operate the EVAL-L99DZ200?

No - USB is only required for GUI-based configuration and real-time diagnostics; the board can operate autonomously using external 12 V automotive supply and preloaded firmware, with all I/Os accessible via headers (J106A/B/C/D) for integration into custom test rigs or vehicle harnesses.
