PIC18F24Q24-E/STX

Microcontrollers Overview

The PIC18F24Q24-E/STX is an 8-bit microcontroller from the PIC18-Q24 series, manufactured by Microchip Technology. It features a RISC core operating at a maximum clock frequency of 64 MHz. The device includes 16 kB of program memory (Flash), 1 kB of data SRAM, and 512 B of EEPROM. It is housed in a 28-pin SSOP package and supports a supply voltage range of 1.8 V to 5.5 V. Key peripherals include a 10-bit ADC with up to 30 external channels, an 8-bit DAC, two high-speed comparators, and multiple communication interfaces such as I2C, SPI, and UART.

Microcontrollers Feature Summary

• Multi-voltage I/O (MVIO) capability allows independent operation of I/O pins within a 1.62 V to 5.5 V range, separate from the main VDD voltage level.
• Integrated Direct Memory Access (DMA) controllers reduce CPU overhead by handling peripheral-to-memory data transfers automatically.
• Advanced Analog-to-Digital Converter (ADCC) supports hardware capacitor voltage divider (CVD) for touch sensing and includes automatic mathematical functions like averaging and filtering.
• Vector Interrupt (VI) controller provides fixed interrupt response latency of three instruction cycles with selectable priority levels.

Microcontrollers Applications

• Sensor interface circuits requiring multi-voltage domain compatibility
• Real-time control systems utilizing DMA for efficient data processing
• Communication applications supporting LIN, DMX-512, or DALI protocols via UART

Microcontrollers Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature range (-40°C to +125°C) compared to the industrial grade variant. Confirm the 'STX' suffix corresponds to the SSOP-28 tube packaging format. Ensure the ordering part number matches the exact pinout and memory configuration required for the design. Cross-reference the datasheet revision date to confirm peripheral availability and electrical characteristics.

Microcontrollers Selection Notes

Select this component when multi-voltage I/O flexibility is required alongside standard 8-bit performance. The inclusion of an 8-bit DAC and hardware CVD support makes it suitable for analog-heavy applications. Compare against the PIC18F24Q10 if fewer I/O pins or different peripheral sets are sufficient. Consider the SSOP-28 package constraints for PCB layout and thermal management requirements.

Microcontrollers Part Context

This device belongs to the PIC18-Q24 family, which emphasizes low power consumption and enhanced peripheral integration. It shares architectural similarities with other Q-series devices but offers specific memory and I/O configurations tailored for cost-sensitive embedded applications. The family supports modern development tools and programming interfaces for streamlined deployment.

Microcontrollers Replacement Considerations

The PIC18F24Q24-I/SS is a verified substitute offering identical functional specifications but limited to the industrial temperature range (-40°C to +85°C). Verify that the application environment remains within the lower temperature bounds before substituting. Other pin-compatible variants may exist within the same package type but require memory and peripheral verification.
