Frequently Asked Questions
What USB specification does PIC18F2455-I/SO support and how does that simplify firmware development?
PIC18F2455-I/SO integrates a USB 2.0 full-speed transceiver running at 12 Mbps, allowing the microcontroller to enumerate directly as a HID, CDC, or vendor-class device without an external USB bridge chip. Microchip provides free USB stack libraries, reducing firmware development time significantly for applications such as virtual COM ports, HID keyboards, or custom USB instruments.
How much flash and RAM does PIC18F2455-I/SO provide for a mid-complexity control application?
PIC18F2455-I/SO includes 24 KB of self-programmable flash program memory and 2048 bytes of SRAM data memory, supported by 256 bytes of EEPROM for non-volatile parameter storage. This is sufficient for a bootloader plus application code in motor-control, USB data-logger, or protocol-bridge designs running at up to 48 MHz on an 8-bit PIC18 core.
Which package does PIC18F2455-I/SO use, and what ADC capability is available for sensor interfaces?
PIC18F2455-I/SO is housed in a 28-pin SOIC package, which is hand-solderable and compatible with standard prototyping adapters. It features a 10-bit successive-approximation ADC with up to 13 multiplexed input channels, enabling simultaneous sampling of temperature, pressure, or voltage sensors without external ADC ICs in data-acquisition or process-monitoring designs.
At what minimum supply voltage can PIC18F2455-I/SO operate, and what design advantage does this offer?
PIC18F2455-I/SO operates at a minimum of 2 V supply voltage when clocked at up to 4 MHz, which is within the discharge range of two AA alkaline cells or a single-cell LiPo at end-of-life. This extended low-voltage operation allows battery-powered USB devices to remain functional longer without requiring a voltage-boosting regulator, lowering component count and quiescent current in portable instruments.
