It is a member of the M68300/68HC16 Family of modular microcontrollers. M68HC16 controllers are built up from standard modules that interface via a common internal bus. Standardization facilitates rapid development of devices tailored for specific applications. The MC68HC16Y1 incorporates a true 16-bit CPU (CPU16), a single-chip integration module (SCIM), an 8/10-bit analog-to-digital converter (ADC), a multichannel communication interface (MCCI), a general-purpose timer (GPT), a time processing unit (TPU), a 2 Kbyte standby RAM module with TPU ROM emulation capability (TPURAM), and a 48 Kbyte masked ROM module (MRM). These modules are interconnected by the Motorola intermodule bus (IMB). The MC68HC16Y1 can either synthesize an internal clock signal from an external reference, or use an external clock input directly. Operation with a 32.768 kHz reference frequency is standard, but operation with a 4.0 MHz reference is available as an option — contact your Motorola representative for more information. System hardware and software allow changes in clock rate during operation. Because the MC68HC16Y1 is a fully static design, register and memory contents are no...
