Integration
Integration calculations
Figures below are calculated from the PJ2302T01-28H40P’s 320×240 resolution and SPI / 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 | 174 PPI |
|---|---|
| Native orientation | Landscape (320×240) |
| 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 |
| RGB pixel clock for 60 Hz | ≈ 5.5 MHz (incl. ~20% blanking) |
| RGB bus width | 24 data lines (16.7M colors) + PCLK, HSYNC, VSYNC, DE; can be wired as 16-bit RGB565 with the low bits tied |
Hosts with a native SPI / 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.
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.
