简介：The PIC18-Q24 microcontroller family is available in 28/40/44/48-pin devices for sensor-interfacing, real-time
control and communication applications. The family showcases a Multi-Voltage I/O (MVIO) interface with
multiple pins I/O powered by an alternative VDD pin, allowing these pins to operate at a different voltage
domain than the rest of the microcontroller. This family also features a 10-bit Analog-to-Digital Converter with
Computation (ADCC) capable of 300 ksps and the 8-bit Signal Routing Port module to interconnect digital
peripherals without using external pins.
Additionally, the PIC18-Q24 microcontroller family offers Enhanced Code Protection features that can be used
to provide increased security and protection of user firmware and data. These Enhanced Code Protection
features include the ability to disable the programming and debugging interface to allow for one time device
programmability and effectively block any unauthorized attempts to communicate with the device via the
ICSP™ interface.
Additional features include vectored interrupt controller with fixed latency for handling interrupts; system bus
arbiter; Direct Memory Access (DMA) capabilities; Universal Asynchronous Receiver-Transmitter (UART) with
support for asynchronous, DMX-512, Digital Addressable Lighting Interface (DALI®) and Local Interconnect
Network (LIN) protocols; Serial Peripheral Interface (SPI); and I2C. This family also includes memory features
such as Memory Access Partition (MAP) and the Device Information Area (DIA) which stores factory calibration
values to help improve temperature sensor accuracy.
