PIC16(L)F1777/8/9 28/40/44-Pin, 8-Bit Flash Microcontroller Description
PIC16(L)F1777/8/9 microcontrollers feature a high level of integration of intelligent analog and digital peripherals for a wide range of applications, such as lighting, power supplies, battery charging, motor control and other general purpose applications. These devices deliver multiple op amps, 5-/10-bit DACs, high-speed comparators, 10-bit ADC, 10-/16-bit PWMs, programmable ramp generator (PRG) and other peripherals that can be connected internally to create closed- loop systems without using pins or the printed circuit board (PCB) area. The 10-/16-bit PWMs, digital signal modulators and tri-state output op amp can be used together to create a LED dimming engine for lighting applications. The peripheral pin select (PPS) functionality provides flexibility, eases PCB layout and peripheral utilization by allowing digital peripheral pin mapping to an I/O.
