Pin-, Peripheral- and Tool-compatible Eight- and 32-bit MCUs
Freescale introduced the first two members of its new Flexis Series of microcontrollers (MCUs). The MC9S08QE128 based on the S08 core, and MCF51QE128, based on the ColdFire V1 core, are said to be the industry's first 8- and 32-bit MCUs with pin-for-pin compatibility and a common set of on-chip peripherals and development tools. The series provides the 8- to 32-bit "connection point" on Freescale's Controller Continuum roadmap for compatible 8- and 32-bit architectures. The Flexis QE128 family enables developers to migrate between low-end and high-performance embedded designs with ease, speed, and ultra-low-power operating efficiency. The MCUs can run off of an external 32 kHz oscillator that consumes <1 µA of current. The Flexis QE devices also have an internal voltage regulator, which helps enable fast wake up from stop modes with a typical wake-up time of 6µs. Stop modes for the Flexis QE128 devices offer 370 nA of current in the lowest power stop mode. Clock gating also can be used to disable clocks to unused modules, further reducing run-mode power consumption. Migration between 8- and 32-bit is via a quick MCU swap. Using a common integrated tool suite, developers don't have to learn new code and tools.
