STMicroelectronics DK4000-C167-110

Overview

DK4000-C167-110 from STMicroelectronics is an evaluation and development board designed specifically for the Infineon C167CR microcontroller family and integrated PSD4135G2 Programmable System Device. It supports JTAG In-System Programming (ISP) and In-Application Programming (IAP), features a 2×16 character LCD display, UART interface, JTAG port, reset button, DIP switch for memory source selection, and on-board 8KB SRAM. It is used to validate memory-swapping architectures and field-upgradable firmware in industrial embedded systems.

For engineers reviewing the DK4000-C167-110 datasheet, DK4000-C167-110 pinout, DK4000-C167-110 application, or DK4000-C167-110 equivalent, this board serves as a production-ready platform for prototyping C167CR-based designs with PSD4000 Flash memory integration, ISP/IAP validation, hardware test execution (hwtest.obj), and memory map configuration using PSDsoft Express.

Technical Context

The DK4000-C167-110 implements a dual-memory execution architecture where the C167CR MCU can boot from either the PSD's Boot Flash (csboot0/1) or Main Flash (FS0), controlled via a DIP switch that sets bit6 (exe_src_a) in the PSD PAGE register. This enables runtime memory swapping without MCU reset.

It integrates IEEE 1149.1-compliant JTAG for full-device programming (PLD, configuration registers, Boot/Main Flash, SRAM initialization), independent of MCU operation. The UART interface supports IAP over serial communication at 19200 baud, 8N1, enabling field updates via CAN, Ethernet, or UART channels as defined by the PSD's dual-Flash architecture.

The DK4000-C167-110 belongs to ST's PSD Development Kit product line, engineered to accelerate adoption of PSD4000 Flash-based system-on-chip solutions with C167CR compatibility, enabling rapid validation of memory-mapped IAP, JTAG ISP, and PLD-configurable peripheral interfacing.

FAQ

What is the role of the DIP switch on the DK4000-C167-110?

The 4-position DIP switch configures boot source selection: position SW1 controls the exe_src_a bit in the PSD PAGE register, determining whether the C167CR executes from Boot Flash (csboot0/1) or Main Flash (FS0). This enables hardware-triggered memory swapping without software intervention or reset.

Does the DK4000-C167-110 support In-Application Programming (IAP)?

Yes - the board supports IAP via UART using the included hwtest.obj and iap.obj firmware bundles. The PSD4135G2's dual independent Flash arrays allow the C167CR to execute from one array while erasing/programming the other, enabling robust field updates over serial, CAN, or Ethernet interfaces.

Which software tools are required to program the PSD4135G2 on this board?

PSDsoft Express (Windows) is mandatory for JTAG ISP programming and PLD configuration. It supports device selection (PSD4000 series), memory map definition, pin function assignment, and JTAG operations. Keil C166 v4.03+ is required to compile C-level code; Infineon DAVE 2.0 was used for original demo projects.

Is the LCD display functional during JTAG ISP programming?

No - the LCD remains non-operational during JTAG ISP because the JTAG interface asserts !RST to hold the C167CR in reset, disconnecting it from the bus. The PSD is programmed independently, and the display only activates after reset release and successful MCU boot from configured Flash memory.
