STMicroelectronics DK900-HC11-110

Overview

DK900-HC11-110 from STMicroelectronics is a complete hardware development kit for the PSD9xxF family of Flash Programmable System Devices (PSDs), integrating an 8032-compatible MCU, JTAG ISP programmer (FlashLINK), UART-based IAP capability, LCD display, and power supply - enabling full evaluation of in-system and in-application programming on PSD913F2 or PSD934F2 devices in industrial control and embedded firmware update applications.

For engineers reviewing the DK900-HC11-110 datasheet, DK900-HC11-110 pinout, DK900-HC11-110 application, or DK900-HC11-110 equivalent, this kit supports hands-on validation of IEEE 1149.1-compliant JTAG ISP, dual-bank Flash architecture for field firmware updates, 8051-family code development, and real-time UART-driven memory reprogramming without MCU reset.

Technical Context

The DK900-HC11-110 implements a dual-mode programmability architecture: JTAG ISP operates independently of the MCU to program MAIN FLASH (128k×8 or 256k×8), BOOT FLASH (32k×8), PLD logic, and configuration registers; IAP leverages the PSD's two independent Flash banks to allow concurrent execution and reprogramming via UART using PSDload software.

Hardware integration includes an 8032 MCU (44-pin PLCC), 2×16-character LCD, JTAG port (IEEE 1149.1), UART serial interface (null-modem compatible), SRAM expansion pads (for 62256/68257), and jumper-configurable settings for RESET polarity, address mapping (A0–A3), and control signal routing (/PSEN, /RD, /WR).

FAQ

Is DK900-HC11-110 compatible with PSD9xxF devices other than PSD913F2 and PSD934F2?

Yes - the DK900-HC11-110 supports the full PSD9xxF family per ST's documentation, including PSD914F2, PSD933F2, and PSD954F2. Jumper configurations (JP5–JP9) and PSDsoft Express project setup must match the target device's memory map, PLD resources, and pinout. All supported parts share identical JTAG and IAP architecture.

Does DK900-HC11-110 include pre-programmed firmware or require initial JTAG programming?

The DK900-HC11-110 ships with a blank PSD9xxF device. Initial programming requires the included FlashLINK JTAG programmer and PSDsoft Express software - no factory-loaded firmware is present. The first ISP operation loads boot code, configuration, and PLD logic to enable subsequent UART-based IAP.

Can the DK900-HC11-110 be used as a standalone JTAG programmer for other PSD9xxF-based designs?

Yes - once configured, the DK900-HC11-110 functions as a low-cost, production-capable JTAG ISP programmer for any PSD9xxF device on external boards. The FlashLINK module connects via ribbon cable to standard 10-pin JTAG headers, and PSDsoft Express supports batch programming and configuration file reuse across multiple units.

What software components are included, and where are they sourced?

No physical media contains the software - PSDsoft Express, PSDload, and demo binaries (Uart1.hex, Iap_80Ex.psd, etc.) are downloaded from ST's official website (st.com/psm). The CDROM included with DK900-HC11-110 contains only documentation, schematics, and application notes - all executable tools require online download and license registration.
