Microcontroller subsystems

Microcontroller IP Cores

A wide range of microcontroller cores, starting with the 8-bit industry standard 8051, extended with 16-bit 80251 compatible, and going up to RISC-V 32-bit.

All Dolphin Integration offering was built in order to insure a smooth evolution from the wide know 8051 legacy solutions to a new generation of RISC-V 32-bits microcontrollers.


Various peripherals such as a AHB compliant Cache controller, I/O ports, timers, serial interfaces, memory interface...

SmartVision™ IDE

A complete offering for software development and debug

SmartVision™ IDE embeds advanced application software debug capabilities thanks to the modeling and simulation of the complete sub-system including processors, memories and peripherals.

BIRD™, a full featured on-chip debug solution suitable for die area optimized microcontrollers.

"We selected the MCU core from Dolphin Integration for its reliability. Dolphin Integration's MCU core has already demonstrated its maturity, as it was used in ASICs designed to replace standard components after their have become obsolete."

CTO - Beijing TMC

“The choice of the Dolphin Integration’s cache controller for our SoC was an excellent trade-off between price, performance and low power consumption compared to other offers such as ARM. We are highly confident for the integration phase, which is simplified by the support of standard interfaces. The innovative self-adaptive module, dynamically upgrading cache configuration according to the executed program, is very helpful in targeting very low power applications that require performance.”

Dolphin Integration powers its offering of microcontroller cores with a complete and integrated platform for application software development, debug and power consumption estimation.

The use of SmartVision™ IDE for application software development and debug is two-fold:

  • In simulation thanks to modeling of the sub-system, including peripherals and memories and power consumption estimation
  • On-chip combined combined with an In-Circuit Emulator (ICE), BIRD™, and an USB adapter named S-Link

RISC-V is a state of the art open-source Instruction Set Architecture on its way to become an industry standard. It benefits from the best design techniques in computer design and has been designed to enable low area and efficient implementations of the microarchitecture.

Dolphin Integration is a member of the RISC-V Foundation which aims to develop a wide ecosystem with +60 members involved in processor, peripherals and embedded software design.
