Freescale MC9S12D64VFUE

HCS1225 МГц64 КБ (64К x 8)

Overview

Designed for automotive multiplexing applications, members of the MC9S12D64VFUE of 16 bit Flash based microcontrollers are fully pin compatible and enable users to choose between different memory and peripheral options for scalable designs. All MC9S12D64VFUE devices are composed of standard on-chip peripherals including a 16-bit central processing unit (CPU12), up to 512K bytes of Flash EEPROM, 14K bytes of RAM, 4K bytes of EEPROM, two asynchronous serial communications interfaces (SCI), three serial peripheral interfaces (SPI), IIC-bus, an enhanced capture timer (ECT), two 8-channel 10-bit analog-to-digital converters (ADC), an eight-channel pulse-width modulator (PWM), J1850 interface and up to five CAN 2.0 A, B software compatible modules (MSCAN12). System resource mapping, clock generation, interrupt control and bus interfacing are managed by the system integration module (SIM).
