Data sources
- Specifications from the product page of the factory that builds the PJ2401H28-22H45P200 (Shenzhen PengJi Photoelectricity Co., Ltd.).
- Brightness is the standard-backlight typical value encoded in the PengJi part number (e.g. …P400 = 400 cd/m²), cross-checked against PengJi's product table and datasheets; other backlight levels can be built.
- Confirm final values against the datasheet supplied with samples.
Integration
Integration calculations
Figures below are calculated from the PJ2401H28-22H45P200’s 240×320 resolution and SPI / MCU (8080 parallel) / RGB (parallel), so you can size the host before requesting samples. Refresh rates are theoretical bus limits; real throughput is lower once command overhead and rendering time are included.
| Pixel density | 167 PPI |
|---|---|
| Native orientation | Portrait (240×320); rotate in the driver for landscape UIs |
| Full frame buffer | 150 KB at RGB565 · 225 KB at RGB888 |
| SPI full-frame refresh (RGB565, theoretical) | 33 fps at 40 MHz · 65 fps at 80 MHz |
| 8080 parallel refresh (theoretical, 10 MHz WR) | 100+ fps on a 16-bit bus · 65 fps on an 8-bit bus |
| RGB pixel clock for 60 Hz | ≈ 5.5 MHz (incl. ~20% blanking) |
| RGB bus width | 16 data lines (65K colors) + PCLK, HSYNC, VSYNC, DE |
At 200 cd/m² it is sized for indoor use; the backlight can be upgraded for brighter environments.
Hosts with a native SPI / MCU (8080 parallel) / RGB (parallel) peripheral
SPI up to 80 MHz; the 150 KB RGB565 frame fits in internal SRAM.
- STM32, RP2040, nRF52
Any MCU with an SPI peripheral and DMA; partial-buffer rendering keeps RAM use low.
LCD_CAM peripheral drives 8/16-bit 8080 (i80) panels with DMA.
- STM32 with FSMC/FMC
The external memory controller maps the panel as memory for fast writes.
RGB LCD peripheral (16-bit RGB565) with the 150 KB frame buffer in PSRAM.
- STM32 with LTDC
F429/F7/H7 families drive 16- to 24-bit RGB panels from external SDRAM.
- Raspberry Pi (DPI)
Parallel RGB over the GPIO header via the DPI overlay.
Interface support is based on each processor’s published display peripherals, not a bench test of this module. Ask us for tested init code.
