Embedded - Microcontrollers

The MC9S12XEP100MAL is an integrated 8-bit microprocessor with enhanced features and performance. It was designed as an extension of Freescale\'s S12XE family, specifically for applications needing advanced non-volatile memory storage and flexible master/slave communication architectures. This MCU combines performance, low power consumption, and enhanced flexibility for cost-sensitive applications.

Application Fields

The MC9S12XEP100MAL is suitable for applications needing greater control such as: automotive systems, household appliances, industrial control and automation, medical applications, and railway systems. The broad range of features and peripherals allow the MCU to perform complex tasks while its small package size, low power consumption and high level of integration enable developers to keep costs low.

In automotive applications, the MCU is a great choice for motor control and safety-related functions. It is possible to use the enhanced non-volatile memory storage to securely store critical safety data and parameters. Its synchronous and asynchronous serial interfaces enable integration with a variety of automotive ECUs. Additionally, the sustained high-speed core frequency of 10-64 MHz provides the precision and performance needed in such applications.

In industrial applications, the MCU is ideal for industrial control, machine automation and process control. Its integrated peripherals such as Timers/Counters/PWM, A/D/D/A converters, Parallel I/Os and I/O expanders enable efficient machine control. The expanded address spaces from 4K to 32K, the block move data transfer capability and all this in a low power consuming 16-bit 80 MHz package makes it suitable for a wide range of industrial control tasks.

Finally, the MCU is also suited for medical applications where patient safety is of utmost importance. Its numerous communication options allow it to be easily integrated into any healthcare environment. Its security features also ensure that patient data remains secure.

Working Principle

The MC9S12XEP100MAL is based on the S12X family\'s core, a proprietary architecture. It is coupled with an enhanced non-volatile memory controller and several peripherals (see Figure 1). The core runs at 10-64 MHz making it ideal for real-time applications.
