PIC18F4525T-I/PT

Microcontrollers Overview

The PIC18F4525T-I/PT is a 44-pin TQFP enhanced Flash microcontroller from the PIC18(L)Fx525 family. It features 48 KB of Flash program memory, 3968 bytes of SRAM, and 1024 bytes of Data EEPROM. The device supports an operating frequency up to 40 MHz with a wide voltage range of 2.0V to 5.5V. Key peripherals include a 10-bit ADC with 13 channels, one CCP module, one ECCP module, MSSP supporting SPI and I2C, and an Enhanced USART.

Microcontrollers Feature Summary

• Incorporates nanoWatt technology for significant power reduction through multiple idle modes and low-consumption modules.
• Features an optional extended instruction set designed to optimize re-entrant code for high-level language compilers.
• Includes self-programmability under software control to enable in-field application updates via bootloader routines.
• Provides flexible oscillator structures including an internal block with PLL support for clock speeds up to 40 MHz without external crystals.

Microcontrollers Applications

• Power-sensitive embedded systems requiring low current consumption
• Applications needing self-updatable firmware via bootloader
• Industrial control systems utilizing serial communication protocols
• Battery-operated devices leveraging multiple power-managed sleep modes

Microcontrollers Procurement Notes

Verify the 'T' suffix indicates tape-and-reel packaging rather than tube packaging. Confirm the 'I' suffix corresponds to the industrial temperature range specifications. Ensure the datasheet revision matches the silicon version required for your design compatibility.

Microcontrollers Selection Notes

Select this component when 48 KB of program memory and 13 analog input channels are required in a 44-pin package. Consider the PIC18F4625 if higher memory capacity is needed while maintaining pin compatibility. Evaluate the PIC18LF4525 variant if strict low-voltage operation below 4.2V is necessary.

Microcontrollers Part Context

This part belongs to the PIC18F2525/2620/4525/4620 family of 28/40/44-pin enhanced Flash microcontrollers. It shares core architecture and peripheral sets with the PIC18F2525 and PIC18F4620, differentiated primarily by memory size and I/O port availability within the same package lineup.
