MCU 8-bit HC05 CISC 1240byte EPROM 3.3V/5V 16-Pin SOIC W Rail
- Robust noise immunity
- 4.0-MHz internal operating frequency at 5.0 V
- 1240 Bytes of EPROM/OTPROM (electrically programmable read-only memory/one-time programmable read-only memory), including eight bytes for user vectors
- 64 bytes of user RAM
- Peripheral modules:
- 15-stage multifunction timer
- Computer operating properly (COP) watchdog
- 10 bidirectional input/output (I/O) lines, including:
- 10-mA sink capability on all I/O pins
- Software programmable pulldowns on all I/O pins
- Keyboard scan with selectable interrupt on four I/O pins
- 5.5-mA source capability on six I/O pins
- Selectable sensitivity on external interrupt (edge- and level-sensitive or edge-sensitive only)
- On-chip oscillator with connections for:
- Crystal
- Ceramic resonator
- Resistor-capacitor (RC) oscillator (MC68HRC705KJ1) with or without external resistor
- External clock
- Low-speed (32-kHz) crystal (MC68HLC705KJ1)
- Memory-mapped I/O registers
- Fully static operation with no minimum clock speed
- Power-saving stop, halt, wait, and data-retention modes
- External interrupt mask bit and acknowledge bit
- Illegal address reset
- Internal steering diode and pullup resistor from RESET pin to VDD
- Selectable EPROM security(1)
- Selectable oscillator bias resistor
