PIC18F27/47Q10 Operating Characteristics
• Operating Voltage Range: – 1.8V to 5.5V • Temperature Range: – Industrial: -40°C to 85°C – Extended: -40°C to 125°C
Power-Saving Operation Modes
• Doze: CPU and Peripherals Running at Different Cycle Rates (typically CPU is lower) • Idle: CPU Halted While Peripherals Operate • Sleep: Lowest Power Consumption • Peripheral Module Disable (PMD): – Ability to selectively disable hardware module to minimize active power consumption of unused peripherals • Extreme Low-Power mode (XLP) – Sleep: 500 nA typical @ 1.8V – Sleep and Watchdog Timer: 900 nA typical @ 1.8V
Digital Peripherals
• Configurable Logic Cell (CLC): – Integrated combinational and sequential logic • Complementary Waveform Generator (CWG): – Rising and falling edge dead-band control – Full-bridge, half-bridge, 1-channel drive – Multiple signal sources • Capture/Compare/PWM (CCP) modules: – Two CCPs – 16-bit resolution for Capture/Compare modes – 10-bit resolution for PWM mode • 10-Bit Pulse-Width Modulators (PWM): – Two 10-bit PWMs • Serial Communications: – Two Enhanced USART (EUSART) with Auto-Baud Detect, Auto-wake-up on Start, RS-232, RS-485, LIN compatible – SPI – I2C, SMBus and PMBus™ compatible • Up to 35 I/O Pins and One Input Pin: – Individually programmable pull-ups – Slew rate control – Interrupt-on-change on all pins – Input level selection control • Programmable CRC with Memory Scan: – Reliable data/program memory monitoring for Fail-Safe operation (e.g., Class B) – Calculate CRC over any portion of Flash or EEPROM – High-speed or background operation • Hardware Limit Timer (TMR2/4/6+HLT): – Hardware monitoring and Fault detection © 2019 Microchip Technology Inc.
