68HC916X1 : 16 Bit Microcontroller

 

The 68HC916X1 is a high-speed 16 bit control unit that combines high-performance data manipulation capabilities with powerful peripheral subsystems and is upwardly code compatible with the 68HC11 Family of microcontrollers. This MCU is built up from standard modules that interface through a common intermodule bus (IMB).

The 68HC916X1 incorporates a true 16 bit central processing unit (CPU), a single chip integration module (SCIM), an 8/10 bit analog-digital converter (ADC), a queued serial module (QSM), a general purpose timer (GPT), a 2 Kbyte static standby RAM module (SRAM) a 2 Kbyte block-erasable flash EEPROM (BEFLASH) and a 48 Kbyte flash EEPROM module (FLASH).
