Key Features

  • 64 KB of Flash program memory with 19-year YTEOL for long-life embedded product development
  • 8-bit PIC18 CPU core running at up to 64 MHz with efficient single-cycle instruction execution
  • Integrated ADC and DAC channels enabling mixed-signal sensor front-end designs without external ICs
  • Compact 14-pin TSSOP package (TSSOP-14) for space-constrained PCB designs in consumer and industrial products
  • Rich peripheral set including timers, UART, SPI, and I2C for versatile connectivity in IoT nodes

Applications

The PIC18F06Q40-I/ST is well suited for IoT sensor nodes and home automation controllers that need mixed-signal capability—ADC for sensor acquisition and DAC for analog output—at up to 64 MHz within a 14-pin TSSOP footprint. Industrial control systems, smart utility meters, and battery management modules benefit from its 64 KB Flash space, which accommodates communication stacks (UART or I2C) alongside application firmware with room to spare. Consumer electronics and HVAC control designs that prioritize low BOM count and compact PCB area make use of its integrated analog peripherals to eliminate external ADC and DAC chips.

Frequently Asked Questions

How much Flash memory does the PIC18F06Q40-I/ST have and is it sufficient for a full application with UART communication?

The PIC18F06Q40-I/ST provides 64 KB of Flash program memory, which is ample for an 8-bit PIC18 application including a UART or I2C driver, a sensor acquisition routine, and a lightweight application loop. Typical PIC18 UART libraries occupy under 4 KB, leaving more than 60 KB for application code and data tables, supporting moderately complex embedded firmware without external memory.

Does the PIC18F06Q40-I/ST include both ADC and DAC peripherals on-chip, and how does this reduce system BOM?

Yes, the PIC18F06Q40-I/ST integrates both an ADC and a DAC in a single 14-pin TSSOP package. This eliminates at least 1 to 2 external converter ICs, saving board space and reducing BOM cost by several dollars per unit. The ADC enables direct connection of resistive or voltage-output sensors, while the DAC provides an analog reference or control signal output without additional circuitry.

What is the maximum operating clock frequency of the PIC18F06Q40-I/ST and how does this affect real-time control tasks?

The PIC18F06Q40-I/ST operates at up to 64 MHz, executing most single-word PIC18 instructions in 1 clock cycle (62.5 ns). This throughput allows a control loop running at 10 kHz to complete in under 100 µs, leaving at least 90% of CPU bandwidth available for communication handling and sensor sampling in time-critical embedded applications.

Which package does the PIC18F06Q40-I/ST use, and does its pin count limit peripheral availability?

The PIC18F06Q40-I/ST comes in a 14-pin TSSOP package with 0.65 mm pitch. While 14 pins limits the number of simultaneously available GPIO lines to approximately 12, the internal multiplexed peripherals (ADC inputs, DAC output, UART, SPI, I2C) share those pins selectively, so designs requiring only 1 or 2 communication interfaces and up to 8 analog inputs are well served without sacrificing package compactness.
