Product Details

PIC18(L)FxxK42 MCUs integrate a rich set of core independent peripherals, intelligent analog peripherals and large Flash/RAM/EEPROM memories. These 28-, 40- and 48-pin devices also offer a host of low power features, performance improvements and design flexibility options that easily and rapidly enable the complex set of functions required by many of today's embedded control applications.

Vectored Interrupt (VI) capability - Faster interrupt response time
Interrupt Vector Table
Programmable single or dual priority
Two level hardware context saving
Direct Memory Access (DMA) controllers - Move data between without CPU
Eliminates need for CPU involvement in data transfers
Access to all memory spaces and peripherals
Flexible source and destination message sizes
Programmable DMA priority
Memory Access Partition (MAP) - Customize flash partitioning with bootloader write protection
