The MCF5253CVM140 is an embedded microcontroller, widely used in applications such as consumer electronics, automotive, and industrial control. It features an ARM Cortex-M4 processor core with up to 192K of on-chip Flash memory and 8K of RAM.

The MCF5253CVM140 belongs to the ColdFire family of microcontrollers, produced by Freescale Semiconductor. It features an ARM Cortex-M4 processor core, with integrated peripherals such as 10-bit analog-to-digital converters (ADCs), digital-to-analog converters (DACs), timers, serial interfaces (three I2Cs, three SPIs), and parallel interfaces (LPC, USB). It also has a wide range of analog and digital peripherals, such as PIOs, Pulse-width-Modulation (PWM) controllers, CAN bus controllers, Quadrature Incremental Encoders, and so on.

MCF5253CVM140’s CPU can execute instructions from either on-chip Flash memory or from external memory. The Flash memory is organized into two memory partitions, one for code and one for data. The code partition is programmed with instructions from the application, while the data partition is programmed with the data needed by the application. MCF5253CVM140 has an on-chip memory protection unit (MPU) which prevents malicious code from being executed.

The MCF5253CVM140 microcontroller’s Cortex-M4 processor core is a 32-bit processor that can execute instructions from either on-chip Flash memory or from external memory.
