PIC18F2515-I/SP

Microcontrollers Overview

The PIC18F2515-I/SP is an 8-bit Flash microcontroller from the PIC18F2X1X/4X1X family, manufactured by Microchip Technology. It features 48 Kbytes of Flash program memory and 3968 bytes of data RAM. The device operates at frequencies up to 40 MHz with a wide voltage range of 2.0V to 5.5V. It includes a 10-bit Analog-to-Digital Converter with 10 channels, two Capture/Compare/PWM modules, Master Synchronous Serial Port (MSSP), and Enhanced USART. The -I/SP suffix indicates an industrial temperature range (-40°C to +85°C) and a 28-pin SPDIP package.

Microcontrollers Feature Summary

• Incorporates nanoWatt technology for significant power reduction through multiple idle modes and low-power peripherals.
• Features an enhanced instruction set optimized for C compiler re-entrant code execution.
• Includes an enhanced addressable USART supporting RS-232, RS-485, and LIN 1.2 protocols.
• Provides flexible oscillator options including internal block, PLL, and external crystal modes.

Microcontrollers Applications

• Industrial control systems requiring robust serial communication
• Battery-powered devices utilizing low-power operating modes
• Motor control applications using CCP/ECCP PWM outputs
• Data acquisition systems integrating analog sensors via ADC

Microcontrollers Procurement Notes

Verify that the ordering suffix matches the required package type and temperature grade. Confirm the specific silicon revision against any applicable errata sheets published by Microchip. Ensure compatibility with development tools such as ICSP programmers or debuggers. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Microcontrollers Selection Notes

Select this component when 48 Kbytes of program memory and 3968 bytes of RAM are required within the 28-pin form factor. Consider the PIC18F2510 if less memory suffices, or the PIC18F2610 for increased capacity. Evaluate the need for the extended instruction set and specific peripheral counts like CCP modules versus ECCP availability in larger packages.

Microcontrollers Part Context

This device belongs to the PIC18F2X1X/4X1X series, which combines high computational performance with high-endurance Flash memory. The family shares core architecture but varies in memory size, I/O count, and peripheral implementation across 28-pin and 40/44-pin packages. It supports single-supply programming and in-circuit debugging via dedicated pins.

Microcontrollers Replacement Considerations

PIC18F2510-I/SP offers identical pinout and features with reduced program memory (32 Kbytes). PIC18F2610-I/SP provides increased memory (64 Kbytes) with the same package and pin configuration. Verify software compatibility and memory usage before substituting these variants.
