Key Features
- Integrated zero-crossing detection op-amp and 8-bit DAC enable analog signal conditioning without external active components, reducing BOM cost in compact designs
- DMA controller transfers data between peripherals and memory at 64 MHz without CPU intervention, freeing the PIC18 core for real-time processing tasks
- ADC with Computation (ADCC) performs hardware averaging, threshold comparison, and low-pass filtering on up to 12 channels, reducing firmware complexity in sensor nodes
Applications
PIC18F04Q41-I/ST targets compact analog sensor nodes, portable instrumentation, and IoT edge devices where an integrated op-amp and hardware ADCC eliminate discrete amplifier stages and reduce PCB area within a TSSOP-14 footprint. Its DMA engine and 64 MHz core support simultaneous ADC sampling, DAC output, and UART communication without software bottlenecks, making it suitable for closed-loop control loops in wearable health monitors and industrial proximity sensors. The device also serves as an ultra-small signal conditioner in 3.3 V or 5 V mixed-signal systems that need on-chip amplification, filtering, and 512 bytes of EEPROM for calibration data.

Frequently Asked Questions
What op-amp specifications does the integrated op-amp in PIC18F04Q41-I/ST provide?
The integrated op-amp in PIC18F04Q41-I/ST offers a gain-bandwidth product of approximately 1 MHz with a slew rate of around 1.5 V/µs, rail-to-rail input and output swing at 1.8 V to 5.5 V supply, and can be configured in inverting, non-inverting, or unity-gain buffer topologies, replacing an external general-purpose op-amp such as MCP6001 in space-constrained designs.
How does the DMA channel in PIC18F04Q41-I/ST improve throughput for data-intensive applications?
The DMA controller moves data between the ADC result register, SRAM, and UART transmit buffer at up to 64 MHz without stalling the CPU, allowing continuous 12-channel ADC sampling at 100 kSPS while the PIC18 core simultaneously runs control algorithms and transmits results over UART at 115.2 kbps — a dual-path throughput that would saturate a non-DMA MCU.
For a wearable sensor with limited board space, how does the TSSOP-14 package of PIC18F04Q41-I/ST help?
The TSSOP-14 package measures only 5.0 mm × 4.4 mm with a 0.65 mm pitch, occupying under 22 mm² of PCB area, which is about 50% smaller than a SOIC-14 equivalent, making it one of the smallest housings available for a PIC18 MCU with an integrated op-amp, DAC, and DMA in a single 14-pin device.
When would PIC18F04Q41-I/ST be selected over PIC18F04Q71 for a cost-sensitive analog design?
PIC18F04Q41-I/ST is selected when the design needs an integrated op-amp and 16 KB of flash at a lower price point, while PIC18F04Q71 adds a higher-resolution ADC and more peripherals at a cost premium; for applications requiring only basic signal amplification and 12-channel 10-bit ADC, the Q41 variant offers the same TSSOP-14 footprint and 1.8 V to 5.5 V range at a reduced unit cost in volumes above 250 pieces.
What EEPROM capacity does PIC18F04Q41-I/ST include, and how does it assist calibration-data storage?
PIC18F04Q41-I/ST integrates 512 bytes of internal EEPROM with endurance of 100,000 write/erase cycles and data retention exceeding 40 years, providing dedicated space for sensor calibration coefficients, factory trim values, and user settings that survive power cycling without consuming any of the 16 KB flash program memory.
