Within the PIC18 architecture, Microchip has products that are developed on three different technologies. All of them share the same instruction set and code base, but are optimized for different things – power, price and integration. The traditional PIC18 family has premium features such as very high endurance flash, true EEPROM for data logging and a wide operating voltage range. The PIC18 J Series is extremely cost effective for complex applications that require >32KB program memory. The J Series offers a compelling solution for cost sensitive applications and has a nice migration capability into Microchip’s PIC24 16-bit family since they share the same manufacturing process and similar connectivity peripherals and protocol software, such as Ethernet and USB. The PIC18 K-series requires very low power and includes true EEPROM on-board. This family is the most cost effective for smaller memory densities. The K-series has the highest performance with 16 MIPS and reaches voltages down to 1.8V. Both PIC18 J Series and K Series include XLP products for very Low Power applications.
