Freescale Semiconductor introduced two interchangeable peripheral modules and 8- and 32-bit microcontroller (MCU) modules for the Tower System development platform. The advanced peripheral modules offer developers 802.11b Wi-Fi and rapid prototyping functionality. The newest MCU modules support Freescale’s MCF5225X 32-bit ColdFire MCU and MC9S08LL64 8-bit MCU. The Tower System provides a comprehensive and highly customizable embedded design environment that allows developers to mix and match MCU and peripheral boards to create reconfigurable development platforms that suit their design needs. Interchangeable modules promote reuse of hardware across multiple architectures, which helps speed time to market. The modular design scales down overall tool costs, while providing an inexpensive entry point.
