68HC12DG128MPV8中文资料摩托罗拉数据手册PDF规格书

The 68HC(9)12DG128 microcontroller unit (MCU) is a 16-bit device composed of standard on-chip peripherals including a 16-bit central processing unit (CPU12), 128K bytes of flash EEPROM (68HC912DG128) or 128K bytes ROM (68HC12DG128), 8K bytes of RAM, 2K bytes of EEPROM, two asynchronous serial communication interfaces (SCI), a serial peripheral interface (SPI), an inter-IC interface (I2C), an enhanced capture timer (ECT), two 8-channel,10-bit analog-to-digital converters (ATD), a four-channel pulse-width modulator (PWM), and two CAN 2.0 A, B software compatible modules (MSCAN12). System resource mapping, clock generation, interrupt control and bus interfacing are managed by the lite integration module (LIM). The 68HC(9)12DG128 has full 16-bit data paths throughout, however, the external bus can operate in an 8-bit narrow mode so single 8-bit wide memory can be interfaced for lower cost systems.
