PICmicro MCUs contain an 8-bit ALU and an 8-bit working register. The ALU is a general pur-pose arithmetic and logical unit. It performs arithmetic and Boolean functions between the data in the working register and any register file. The ALU is 8-bits wide and is capable of addition, subtraction, shift and logical operations.
It’s good to note that not every PIC in any given family has all the features listed in the full Family Reference Manual. Each PIC part number may have additional information on the Microchip website’s product detail page or in the Family Datasheet.
Note 1: In RC oscillator configuration, the OSC1/CLKIN pin is a Schmitt Trigger input. It is not recommended that the PICmicro be driven with an external clock while in RC mode. 2: Not Applicable. 3: Not Applicable. 4: The better of the two specifications may be used.
Microchip has a strength is in EPROM technology. That made it the memory technology of choice for the PICmicro MCU’s program memory. Microchip has minimized the cost difference between EPROM and ROM memory technology, and therefore Microchip can pass these benefits onto our customers.
