The S08QE family, comprised of a pin-compatible 8-bit and 32-bit device duo, is Our first family in the Flexis series. The Flexis series of controllers is the connection point of the NXP® Controller Continuum where 8- and 32-bit compatibility become reality.

The S08QE128 pushes the boundaries of the 8-bit architecture performance with 128 KB of flash, 24 analog-to-digital converter (ADC) channels and delivering up 25 MHz in bus frequency.  The 32-bit MCF51QE128 is pin-, peripheral- and tool-compatible with the 8-bit S08QE128 device. They share a common set of peripherals and development tools, delivering the ultimate in migration flexibility.
