The PIC18F66J93 family of devices offers the advantages of all PIC18 microcontrollers – high computational performance, a rich feature set and economical price – with the addition of a versatile, on-chip LCD driver. These features make the PIC18F87J93 family a logical choice for many high-performance applications where price is a primary consideration. 12-Bit A/D Converter: The PIC18F87J93 family implements a 12-bit A/D converter. A/D converters in both families incorporate programmable acquisition time. This allows for a channel to be selected and a conversion to be initiated, without waiting for a sampling period and thus, reducing code overhead. Data RAM: The PIC18F87J93 family devices have 3,923 bytes of RAM. Devices in the PIC18F87J93 family are available in 64-pin and 80-pin packages
