Microchip Technology PIC18-Q40 8-Bit MCUs with XLP Technology
Microchip Technology PIC18-Q40 8-Bit Microcontrollers with XLP Technology are compact, high-performance MCUs with advanced analog peripherals for sensor and real-time control applications. These devices have a 12-bit Analog-to-Digital Converter with Computation (ADCC) and two 8-bit Digital-to-Analog Converters (DACs) for improved data acquisition and sensor interfacing capabilities. The PIC18-Q40 MCUs include a 16-bit PWM module, which provides dual independent outputs on the same time base. Additional features include a vectored interrupt controller with fixed latency for handling interrupts, system bus arbiter, Direct Memory Access (DMA) capabilities, UART with support for asynchronous, DMX, DALI, and LIN protocols, SPI, I2C, and a programmable 32-bit Cyclic Redundancy Check (CRC) with memory scan.
The PIC18-Q40 MCUs include memory features such as Memory Access Partition (MAP) to support users in data protection and bootloader applications and Device Information Area (DIA), which stores factory calibration values to help improve temperature sensor accuracy.
The Microchip Technology PIC18-Q40 MCUs are offered in small-footprint 14-pin SOIC and TSSOP packages and 20-pin PDIP, SOlC, SSOP, and VQFN packages to support customers in a variety of space-constrained and sensor node applications.
