• Features a 12-bit Analog-to-Digital Converter with Computation and Context Switching extensions for automated signal analysis.
• Includes eight Direct Memory Access (DMA) controllers for hardware-managed data transfers between memory spaces.
• Provides Peripheral Pin Select (PPS) capability for flexible digital I/O pin mapping.

Microcontrollers Applications

• Automotive applications requiring CAN FD connectivity
• Industrial motor control systems utilizing PWM and CWG modules
• Sensor interface designs leveraging high-resolution ADC capabilities
• Power supply management units employing Zero-Cross Detect and comparators

Microcontrollers Procurement Notes

Verify that the suffix 'E' corresponds to the Extended temperature range (-40°C to +125°C) as specified in the datasheet. Confirm the '/P' designation indicates the 40-pin Plastic Dual In-line Package (PDIP). Ensure the specific revision level matches project requirements, as device characteristics may evolve across datasheet revisions.

Microcontrollers Selection Notes

Select this model when 128 KB of program memory and 36 available I/O pins are required within a through-hole package. The PIC18F46Q84 offers higher peripheral density than the PIC18F26Q84 variant. Consider the PIC18F56Q84 if additional I/O pins beyond 36 are necessary for the design.

Microcontrollers Part Context

This component belongs to the PIC18-Q84 family, which provides low-power, high-performance 8-bit processing with XLP Technology. The family supports automotive and industrial environments through integrated communication peripherals and Core Independent Peripherals designed to reduce application complexity.

Microcontrollers Replacement Considerations

PIC18F26Q84-E/P: Offers identical core architecture but reduced memory (128 KB Flash, 12.8 KB RAM) and fewer I/O pins (25 vs 36). Suitable for designs with lower pin count requirements.
