Quick Detail:
High-density Complementary Metal Oxide Semiconductor (HCMOS)
Microcomputer Unit
Description:
The MCHC705B16NCFNE microcomputer (MCU) is a member of Freescale’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 selection; receiver wake-up function
for use in multi-receiver systems
• 8 channel A/D converter
• 2 pulse length modulation systems which can be used as D/A
converters
• One interrupt request input plus 4 on-board hardware interrupt
sources
• Available in 52-pin plastic leaded chip carrier (PLCC), 64-pin
quad flat pack (QFP) and 56-pin
shrink dual in line (SDIP) packages
• Complete development system support available using the MMDS05
development station with the M68HC05B32EM emulation module
• Extended operating temperature range of -40 to +125 °C
