This document introduces the uPSD Turbo series USB microcontroller development kit DK3400 released by STMicroelectronics. The kit is a demo board for the uPSD3400 family of microcontrollers, which feature a fast Turbo Plus 8032 core with a 16-bit code fetch path, full-speed USB port, large Dual Bank Flash memory, large SRAM, numerous peripherals, programmable logic, and a JTAG Debug/In System Programming (ISP) port. The DK3400 kit includes an ED3K4 module and DK3400 motherboard, as well as all the necessary items to explore the uPSD3400 MCU. It also provides demonstration application examples and an evaluation copy of the tools needed to develop and compile code for the uPSD3400.
This manual introduces the Turbo Plus UPSD DK3400 Development Kit, a demo board for the uPSD3400 family of 8051‑class microcontrollers. It describes the kit components, including the ED3K4 module and DK3400 motherboard, and outlines the tools needed for development.
The document details the hardware capabilities of the DK3400 motherboard and ED3K4 module, such as selectable power sources, USB ports, extension connectors, flash memory, LCD display, and various interfaces. It also explains the five operation modes, jumper settings, and provides schematics and revision history.
