Description
The PIC18F8628 devices offers the advantages of all PIC18 microcontrollers – namely, high computational performance at an economical price – with the addition of high-endurance, Enhanced Flash program memory. In addition to these features, the PIC18F8723 introduces design enhancements that make these microcontrollers a logical choice for many high-performance, power-sensitive applications. 12-Bit A/D Converter: The PIC18F8723 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 Like all Microchip PIC18 devices, members of the PIC18F8723 family are available as both standard and low-voltage devices. Standard devices with Enhanced Flash memory, designated with an “F” in the part number (such as PIC18F6628), accommodate an operating VDD range of 4.2V to 5.5V. Low-voltage parts, designated by “LF” (such as PIC18LF6628), function over an extended VDD range of 2.0V to 5.5V.
