Description
PIC18F8393 offers the advantages of all PIC18 microcontrollers – namely, high computational performance at an economical price. In addition to these features, the PIC18F6393/6493/8393/8493 family introduces design enhancements that make these microcontrollers a logical choice for many high-performance, power-sensitive applications. 12-Bit A/D Converter: This module incorporates programmable acquisition time, allowing for a channel to be selected and a conversion to be initiated without waiting for a sampling period and thus, reduces code overhead Devices in the PIC18F6393/6493/8393/8493 family are available in 64-pin (PIC18F6X93) and 80-pin (PIC18F8X93) packages Like all Microchip PIC18 devices, members of the PIC18F6393/6493/8393/8493 family are available as both standard and low-voltage devices. Standard devices with Flash memory, designated with an “F” in the part number (such as PIC18F6393), accommodate an operating VDD range of 4.2V to 5.5V. Low-voltage parts, designated by “LF” (such as PIC18LF6490), function over an extended VDD range of 2.0V to 5.5V
