Product details
Overview
AEK-LCD-DT028V1 from STMicroelectronics is an evaluation board featuring a 2.8" (240×320 pixel) TFT LCD with integrated resistive touch, managed by an on-board TSC2046 SPI touch controller, powered by a 3.3 V LDO (LD1117S33TR), and designed for GUI development with SPC5 MCU discovery boards.
For engineers reviewing the AEK-LCD-DT028V1 datasheet, AEK-LCD-DT028V1 pinout, AEK-LCD-DT028V1 application, or AEK-LCD-DT028V1 equivalent, key selection considerations include SPI interface compatibility with SPC5 MCUs, dual-voltage operation (3.3 V I/O / 5 V display backlight), resistive touch resolution support, and AutoDevKit library integration via STSW-AUTODEVKIT.
Technical Context
The board implements a dedicated SPI-based display interface (TFT_SCK/TFT_SDI/TFT_SDO/TFT_DC/TFT_CS/TFT_RESET) alongside a separate SPI touch interface (TP_CLK/TP_CS/TP_DIN/TP_OUT/TP_IRQ) routed to the TSC2046IPW controller. The LD1117S33TR LDO regulates 3.3 V for logic signals, while VDD5 supplies the display backlight and touch reference.
It interfaces directly with SPC5 MCU discovery boards via a 14-pin SIL header (WR-PHD), supporting both display timing control (DOTCLK, HSYNC, VSYNC) and parallel-mode legacy signals (DB0–DB17, ENABLE, IM0–IM3), though primary operation uses SPI mode per DB4523.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Display Size | 2.8 inch diagonal active area, enabling compact embedded GUIs in space-constrained industrial HMIs. |
| Resolution | 240 × 320 pixels (QVGA), supporting legible text and basic graphics without high memory bandwidth. |
| Touch Interface | SPI-connected TSC2046IPW controller, delivering 12-bit X/Y coordinate data with PENIRQ interrupt signaling. |
| Power Supply | Single 5 V input; onboard LD1117S33TR provides regulated 3.3 V for logic, decoupled with 4.7 µF and 100 nF capacitors. |
| Physical Dimensions | 53 mm × 87 mm PCB footprint, matching mechanical constraints of SPC5 evaluation ecosystems. |
| Compliance | RoHS and WEEE compliant, meeting environmental requirements for industrial and automotive-adjacent prototyping. |

Manufacturer
STMicroelectronics is a global semiconductor leader headquartered in Geneva, designing and manufacturing microcontrollers, analog ICs, power devices, and sensors for industrial, automotive, and consumer applications.
This board belongs to ST's AutoDevKit ecosystem - a hardware-software co-design platform built to accelerate GUI, motor control, and sensor interface development for SPC5 automotive MCUs.
FAQ
Does AEK-LCD-DT028V1 require external firmware to operate?
No. It operates out-of-the-box with ST's SPC5-STUDIO IDE and AutoDevKit library (STSW-AUTODEVKIT), which provides pre-validated drivers, GUI widgets, and touch calibration routines. No custom low-level register programming is needed for basic display or touch functionality.
Can AEK-LCD-DT028V1 be used with non-SPC5 microcontrollers?
Yes - its SPI display and touch interfaces are electrically standard and protocol-compatible with any MCU supporting 3.3 V SPI peripherals and GPIO interrupts. However, ST-provided software libraries and AutoDevKit integration are optimized exclusively for SPC5 MCUs.
What is the role of the TSC2046IPW on this board?
The TSC2046IPW is a dedicated 12-bit resistive touch screen controller that converts analog X/Y voltage measurements into digital coordinates via SPI, generates PENIRQ on touch detection, and supports both single-point and pressure-aware sampling modes per its datasheet.
Is the backlight brightness adjustable?
Yes - the TFT_BLK signal is a PWM-controllable enable line for the display backlight LED circuit. Driving it with a variable-duty-cycle 3.3 V PWM signal (e.g., from an SPC5 timer output) allows dynamic brightness control without external hardware modification.
