The MCF51QE32LH is a ColdFire family 32-bit reduced instruction set computing (RISC) Microcontroller based on V1 ColdFire core and operates at processor core speeds up to 50.33MHz. The QE family, comprised of a pin-compatible 8-bit and 32-bit device duo, is the first family in the flexis series. The Flexis series of controllers is the connection point on the controller continuum, where 8- and 32-bit compatibility becomes reality. The MCF51QE128 device extends the low end of the 32-bit ColdFire controller family with up to 32kB flash memory and a 24-channel, 12-bit analog-to-digital converter (ADC). The 32-bit MCF51QE32 is pin-, peripheral- and tool-compatible with the 8-bit S08QE32 device. They share a common set of peripherals and development tools delivering the ultimate in migration flexibility.
