Freescale"s RS08KB 8-bit microcontroller (MCU) family features an integrated peripheral set that includes a highly efficient RS08 core to support interrupt capability, helping to improve system performance and save additional components costs. The RS08KB family eases migration by offering multiple package and flash size options, along with pin compatibility with other 5-volt families and the CodeWarrior development tool to support other all 8-bit families.
