STMicroelectronics DK3300-ELCD

Overview

DK3300-ELCD from STMicroelectronics is a discontinued but fully documented development kit for the uPSD3334D Turbo 8051 microcontroller, featuring an enhanced graphic LCD, dual USB-JTAG adapters (Keil ULINK and Raisonance R-LINK-ST), RS-232/USB cables, universal 100–240V power supply, and preloaded demonstration firmware for PWM, I²C, SPI, and EEPROM emulation.

For engineers reviewing the DK3300-ELCD datasheet, DK3300-ELCD pinout, DK3300-ELCD application, or DK3300-ELCD equivalent, this kit supports rapid prototyping of embedded control systems using the uPSD3300 family's integrated Flash, SRAM, programmable logic, and JTAG-debuggable 8032 core - with full schematics and sample code publicly archived at st.com/psm/.

Technical Context

The DK3300-ELCD board implements the uPSD3334D MCU (8051-compatible, 48 MHz max, 288 KB Flash, 8 KB SRAM) with on-board peripherals including dual UARTs, I²C interface to M41ST87 real-time clock, SPI bus for M95080W EEPROM and 48PE16 serial flash, 8-channel 10-bit ADC, three PWM outputs, and encoder input support via Port B pins PB5–PB7.

It integrates discrete power regulation (LD1117-3.3V, 78M05-5V), RS-232 level-shifting (ST3232), IrDA transceiver (TFDU4300), and LCD driver circuitry for GXM12232SL 122×32 monochrome graphic display - all accessible through standardized 2×2 and 18×2 headers per schematic Figures 6 and 7.

Key Specifications

Availability

Manufacturer

STMicroelectronics is a global semiconductor leader headquartered in Geneva, Switzerland, specializing in microcontrollers, power management, analog ICs, and automotive-grade silicon.

This kit belongs to ST's legacy uPSD (Universal Programmable System Device) product line - designed to integrate 8051 MCU, Flash, SRAM, PLD, and peripherals into single-chip solutions for cost-sensitive, low-to-mid complexity embedded control applications.

FAQ

Is DK3300-ELCD still in production?

No - DK3300-ELCD is marked "Obsolete Product(s)" in ST's official documentation (Rev. 2.0, Dec 2004). It is no longer manufactured or supported by ST, but full schematics, user manuals, and example code remain publicly archived at st.com/psm/ for legacy design reuse and educational use.

What microcontroller is mounted on the DK3300-ELCD board?

The board is populated with the uPSD3334D - an 8051-compatible Turbo core MCU featuring 288 KB on-chip Dual-Bank Flash memory, 8 KB SRAM, programmable logic blocks, JTAG debug port, and integrated peripherals including dual UARTs, I²C, SPI, 8-channel 10-bit ADC, and three PWM timers.

Can I use modern IDEs like Keil µVision5 or IAR Embedded Workbench with this kit?

Yes - the uPSD3334D is 8051 architecture-compliant and supports standard 8051 toolchains. While the included Raisonance RKIT and Keil µVision2 versions are code-size-limited, modern Keil µVision5 and IAR EW8051 can target the device using the same JTAG interface (ULINK or R-LINK-ST) and memory map defined in the uPSD3300 datasheet.

Where can I find the DK3300-ELCD schematics and firmware examples?

Schematics (ZIP), Quick Start Guide (PDF), and all demonstration code (BANKING.zip, I2C.zip, PWM_ADC.zip, etc.) are hosted on ST's legacy PSM portal: www.st.com/psm/.
