MC9S12DG128MPVE – FREESCALE

The MC9S12DG128MPVE is a high-performance 16-bit microcontroller unit (MCU) from Freescale Semiconductor (now NXP). Fabricated on a 0.25µm process, it features a 128KB Flash memory module for program storage, enabling in-application programming and EEPROM emulation. The device incorporates a 16-bit central processing unit (CPU) operating at a maximum bus frequency of 25MHz, facilitating efficient data processing. Housed in a 112-pin Low-Profile Quad Flat Package (LQFP), the MC9S12DG128MPVE integrates a comprehensive suite of peripherals, including analog-to-digital converters (ADCs), serial communication interfaces (SCI, SPI, I2C), pulse-width modulation (PWM) channels, and timers. Its architecture supports a multiplexed external bus interface for memory expansion and peripheral connectivity. The device operates within a specified voltage range, typically 5V, and is designed for embedded control applications requiring robust performance and integrated functionality.
