MC68HC705JP7 - HCMOS Microcontroller Unit - Motorola, Inc
Surface Mount IC
- Product details:
- Low-cost, M68HC05 core MCU in 28-pin package
- (MC68HC705JP7)
- • 6160 bytes of user EPROM, including 16 bytes of user vectors
- • 224 bytes of low-power user random-access memory (RAM)
- • 64 bits of personality EPROM (serial access)
- • 16-bit programmable timer with input capture and output compare
- • 15-stage core timer, including 8-bit free-running counter
- and 4-stage selectable real-time interrupt generator
- • Simple serial input/output port (SIOP) with interrupt capability
- • Two voltage comparators, one of which can be combined with the
- 16-bit programmable timer to create a 4-channel, single-slope
- analog-to-digital (A/D) converter
- • Output of voltage comparator can drive port pin PB4 directly under
- software control
- • 22 I/O line
- , including high-source/sink current capability
- on 14 I/O pins (MC68HC705JP7)
- • Programmable 8-bit mask option register (MOR) to select mask
- options found in read-only memory (ROM) based versions
- • MOR selectable software programmable pulldowns on all I/O pins
- and keyboard scan interrupt on four I/O pins
- • Software mask and request bit for IRQ interrupt with MOR
- selectable sensitivity on IRQ interrupt (edge- and level-sensitive or
- edge-only)
- • On-chip oscillator with device option of crystal/ceramic
- resonator
- or resistor-capacitor (RC) operation and MOR selectable shunt
- resistor, 2 MΩ by design
