DIABLO16

Overview

The DIABLO-16 Processor is a custom-embedded 4DGL graphics controller designed for OLED and LCD panels. It features an EVE soft-core virtual engine executing compiled 4DGL programs. The chip provides 6 banks of 32750 bytes Flash memory and 32KB SRAM. It interfaces with displays via an 80-Series 16-bit CPU interface, supporting resistive touch screens, SD cards, and audio output. Operating at 3.3V nominal voltage within a 3.0V to 3.6V range, it is housed in a 64-pin TQFP package.

Feature Summary

• EVE virtual engine core running 4DGL bytecode

Procurement Notes

Verify the specific revision number against the latest documentation on the 4D Systems resource centre, as content may change. Confirm that the design supports the required 3.3V logic levels and 3.3V tolerant I/O specifications for all connected peripherals.

Selection Notes

Select this processor for applications requiring standalone embedded graphics or co-processing capabilities. Ensure the target display supports an 80-Series 16-bit wide CPU interface. Verify that the application fits within the 32KB SRAM limit for user data and utilizes the available Flash storage for firmware.

Part Context

The DIABLO-16 belongs to the 4D Labs family of processors, succeeding the Picaso Processor with increased power, flash, and RAM. It is powered by the Extensible Virtual Engine (EVE) and is designed to minimize low-level design effort by providing direct drive signals for compatible displays.
