Flash MCU family features 8- and 32-bit compatibility

Processors’ pin-for-pin compatibility is an industry first

Breaking new ground in 8- and 32-bit microcontroller compatibility, Flexis series microcontrollers 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 first examples are the MC9S08QE128, using a S08 core, and the MCF51QE128, using a ColdFire V1 core.

The family enables developers to very easily migrate between low-end and high-performance embedded designs and features low-power operation that is critical to portable applications. In stop mode the devices consume just 370 nA, and run currents start at 50 µA.

Both chips have up to 8 Kbytes of RAM and 128 Kbytes of flash; a 24-channel 12-bit A/D converter; two analog comparators; two each SCI, I2C, and SPI ports; and one 6-channel and two 3-channel timer PWM modules. The processors operate from 1.8 to 3.6 V and come in LQFP80 and LQFP64 packages with a -40° to 85°C temperature range. Both demo and evaluation boards are available.
