Product Summary
The XC705B32CFN is a low-cost single chip microcomputer. This 8-bit MCU XC705B32CFN contains an on-chip oscillator, CPU, RAM, ROM, EEPROM, A/D converter, pulse length modulated outputs, I/O, serial communications interface, programmable timer system and watchdog. The fully static design allows operation at frequencies down to dc to further reduce the already low power consumption to a few micro-amps.
Parametrics
XC705B32CFN absolute maximum ratings: (1)Supply voltage, VDD: – 0.5 to +7.0 V; (2)Input voltage (Except VPP1), VIN: VSS – 0.5 to VDD + 0.5 V; (3)Input voltage- Self-check mode (IRQ pin only), VIN: VSS – 0.5 to 2VDD + 0.5 V; (4)Operating temperature range, TA: 0 to +70℃; (5)Storage temperature range, TSTG: – 65 to +150℃; (6)Current drain per pin (excluding VDD and VSS), ID: 25mA.
Features
XC705B32CFN features: (1)Fully static design featuring the industry standard M68HC05 family CPU core; (2)On chip crystal oscillator with divide by 2 or a software selectable divide by 32 option (SLOW mode); (3)2.1 MHz internal operating frequency at 5V; 1.0 MHz at 3V; (4)High speed version available; (5)176 bytes of RAM; (6)5936 bytes of user ROM plus 14 bytes of user vectors; (7)256 bytes of byte erasable EEPROM with internal charge pump and security bit; (8)Write/erase protect bit for 224 of the 256 bytes EEPROM; (9)Self test/bootstrap mode; (10)Power saving STOP, WAIT and SLOW modes ; (11)Three 8-bit parallel I/O ports and one 8-bit input-only port; (12)Software option available to output the internal E-clock to port pin PC2; (13)16-bit timer with 2 input captures and 2 output compares; (14)Computer operating properly (COP) watchdog timer.
