Microchip PIC18F2520T-I/SO 8-Bit Microcontroller: Features and Applications
The Microchip PIC18F2520T-I/SO is a high-performance 8-bit microcontroller from Microchip Technology's extensive PIC18 family. Housed in a 28-pin SOIC (Small Outline Integrated Circuit) package, this device is engineered for applications that demand a powerful yet cost-effective processing core, robust peripheral integration, and efficient power management. It is particularly suited for complex embedded systems across industrial, automotive, and consumer markets.
Key Features
At the heart of this microcontroller is an enhanced PIC18 architecture capable of operating at speeds up to 40 MHz, providing a substantial 10 MIPS (Million Instructions Per Second) performance. This allows it to handle computationally intensive tasks efficiently.
A standout feature is its substantial on-chip memory. The device boasts 32 KB of Flash program memory and 1.5 KB of RAM, offering ample space for sophisticated application code and data handling. Furthermore, it includes 256 Bytes of EEPROM data memory, which is essential for storing critical data that must be retained even after a power cycle, such as calibration constants or user settings.
The peripheral set is rich and versatile. It includes a 10-bit Analog-to-Digital Converter (ADC) with up to 13 channels, enabling precise measurement of multiple analog signals. For communication, it is equipped with multiple serial interfaces: EUSART (for RS-232, RS-485), SPI, and I2C, making it easy to connect with sensors, displays, memory chips, and other peripherals. It also features Capture/Compare/PWM (CCP) modules and timers, which are crucial for motor control, power conversion, and generating precise waveforms.
Designed for resilience and low-power operation, it supports a wide operating voltage range (2.0V to 5.5V) and features nanowatt-power technology, enabling it to operate effectively in battery-powered applications through various sleep and idle modes.
Primary Applications
The combination of performance, memory, and integrated peripherals makes the PIC18F2520T-I/SO ideal for a wide array of applications:
