HT46C46 mcu equivalent, cost-effective a/d type 8-bit mcu.
* Operating voltage:
* Up to 0.5ms instruction cycle with 8MHz system clock
fSYS=4MHz: 2.2V~5.5V fSYS=8MHz: 3.3V~5.5V
* 13 bidirectional I/O lines (max.)
that interface directly to analog signals, such as those from sensors. The mask version HT46C46, HT46C47 are fully pin a.
