Keil DK251 Version 3.6 Supports DOLPHIN Flip80251

Plano, TX: Keil Software is pleased to announce the release of the DK251 Developer's Kit Version 3.6. New in this version is accurate device simulation for the DOLPHIN Flip80251 Typhoon core. Complete device simulation includes all 251 peripherals and gives users serious benefits for rapid, reliable embedded software development. The DLL-based Advanced Simulation Interface (AGSI) allows developers to add user-defined peripherals.

The DOLPHIN Flip80251 Typhoon is a high-speed CPU core that is based on the 251 architecture. The 251 architecture is a true superset of the industry standard 8051. It is designed for optimal C language performance and removes several 8051 limitations by providing:

  • Large linear 16MBytes address space that avoids memory banking.
  • 32 byte register file with 8-bit, 16-bit, and 32-bit registers.
  • 64KBytes stack for reentrant code and real-time operating systems.
  • 16-bit and 32-bit instructions for direct support of C data types.
  • 16-bit direct and 16-bit/32-bit indirect memory addressing modes.
  • 8051 compatible peripherals with high-speed interrupt system.

The DOLPHIN Flip80251 Typhoon is fully configurable towards customer requirements. Available peripherals include Timers/Counters, Watchdog Timer, Programmable Counter Array, SPI, I2C Master/Slave, HDLC, PWM, and more. The Flip80251 Typhoon is a cost-efficient alternative to 32-bit architectures and provides a true upgrade path for 8051 based products. The 1-cycle pipelined CPU core has a significant performance improvement confirmed by various (benchmarks) but keeps 8051 compatibility for application code.
