MC9S12XEQ512MAL – NXP

The MC9S12XEQ512MAL, manufactured by Freescale Semiconductor (FSC), is a high-performance 16-bit microcontroller unit (MCU) based on the S12X architecture. It features 512KB of on-chip flash memory for program storage and data logging, enabling complex embedded applications. The device operates with a core frequency up to 40MHz, providing significant processing power. The MAL suffix designates a 112-pin Low-profile Quad Flat Package (LQFP) for surface mount assembly. This MCU incorporates a variety of peripherals, including multiple timers, serial communication interfaces (SCI, SPI, I2C), and analog-to-digital converters (ADCs), facilitating interface with external sensors and actuators. Its enhanced memory protection unit (MPU) and error correction coding (ECC) on the flash memory contribute to system reliability and data integrity, crucial for safety-critical applications.
