MC9S12E128CFU

16位微控制器 - MCU 16 Bit 16MHz

Introduction

The MC9S12E128 is a 112/80/64 pin low cost general purpose MCU comprised of standard on-chip peripherals including a 16-bit central processing unit HCS12 CPU, up to 128K bytes of Flash EEPROM, up to 8K bytes of RAM, three asynchronous serial communications interface modules SCI, a serial peripheral interface SPI, an Inter-IC Bus IIC, three 4-channel 16-bit timer modules TIM, a 6-channel 15-bit Pulse Modulator with Fault protection module PMF, a 6-channel 8-bit Pulse Width Modulator PWM, a 16-channel 10-bit analog-to-digital converter ADC, and two 1-channel 8-bit digital-to-analog converters DAC. The MC9S12E128 has full 16-bit data paths throughout. The inclusion of a PLL circuit allows power consumption and performance to be adjusted to suit operational requirements. In addition to the I/O ports available on each module, 16 dedicated I/O port bits are available with Wake-Up capability from STOP or WAIT mode. Furthermore, an on chip bandgap based voltage regulator VREG generates

the internal digital supply voltage of 2.5V VDD from a 3.135V to 5.5V external supply range.
