Product Overview
The PIC18F1330-I is an 18-pin, 8-bit high-performance Flash microcontroller from Microchip Technology featuring the PIC18 architecture with specialized motor control peripherals. With 4096 single-word instructions and a 31-level deep hardware stack, this compact MCU offers 8KB (4K x 16) of Flash program memory, 256 bytes of RAM, and 128 bytes of data EEPROM. Operating at up to 40 MHz (10 MIPS), it integrates a 4-channel 10-bit ADC, three analog comparators, six PWM outputs with power control features, a 16-bit EUSART with LIN support, and an 8 MHz internal oscillator. Designed specifically for motor control and power conversion applications, the PIC18F1330’s Power Control PWM module provides flexible half-bridge/full-bridge drive capabilities with auto-shutdown on fault conditions. Its small 18-pin footprint makes it ideal for space-constrained motor control, power supply, lighting, and automotive applications.
