Quick Detail:
One Time Program Memory, MC68HC705B16 - Motorola, Inc - High-density Complementary metal Oxide Semiconductor (HCMOS) Microcomputer Unit
Description:
- IC MCU 2.1MHZ 15K OTP 52-PLCC MC68HC705B16CFN MOTOROLA
The MC68HC705B16CFN microcomputer (MCU) is a member of Motorola’s MC68HC05 family of
low-cost single chip microcomputers. This 8-bit MCU 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.
Applications:
Fully static design featuring the industry standard M68HC05 family CPU core
• On chip crystal oscillator with divide by 2 or a software selectable divide by 32 option (SLOW
mode)
• 2.1 MHz internal operating frequency at 5V; 1.0 MHz at 3V
• High speed version available
• 176 bytes of RAM
• 5936 bytes of user ROM plus 14 bytes of user vectors
• 256 bytes of byte erasable EEPROM with internal charge pump and security bit
• Write/erase protect bit for 224 of the 256 bytes EEPROM
• Self test/bootstrap mode
• Power saving STOP, WAIT and SLOW modes
• Three 8-bit parallel I/O ports and one 8-bit input-only port
• Software option available to output the internal E-clock to port pin PC2
• 16-bit timer with 2 input captures and 2 output compares
• Computer operating properly (COP) watchdog timer
• Serial communications interface system (SCI) with independent transmitter/receiver baud rate MCU Microcontroller Unit IC MCU 2.1MHZ 15K OTP 52-PLCC MC68HC705B16CFN MOTOROLA
