The PIC18F2520-I/SP microcontroller chip has several uses in embedded systems. Microchip Technology Inc., a leading producer of microcontroller and analog semiconductors, produced the chip in question, a member of the PIC18 family of microcontrollers. This reference manual’s overarching goal is to serve as a thorough introduction to the PIC18F2520-I/SP, detailing its capabilities, potential uses, and programming.
The power consumption of the PIC18F2420/2520/4420/4520 family of devices can be greatly reduced by several characteristics. Important aspects consist of the following:
It is possible to reduce power usage by as much as 90% during code execution by timing the controller from the Timer1 source or the internal oscillator block.
The controller can also function with its central processing unit turned off but its peripherals left on. In these conditions, power usage can drop to as low as 4 percent of what it would be under normal conditions.
User code invokes the powermanaged modes during operation, enabling users to include energy-saving strategies into the application’s code.
The power requirements for both Timer1 and the Watchdog Timer are minimized.
The Enhanced Flash cells used for both the program memory and the data EEPROM have a lifespan that is rated to survive for many thousands of erases and write cycles, specifically, up to 100,000 for the program memory and 1,000,000 for the EEPROM. The expected time that data can be stored without being updated can be considered more than 40 years.
Some devices can write to their own program memory areas and do so under the control of their own internal software. It is feasible to make an application capable of automatically updating itself out in the field by utilizing a bootloader function that is stored in the secure Boot Block at the beginning of the program memory.
An optional enhancement to the PIC18 instruction set is made available by the PIC18F2420/ 2520/4420/4520 family. This extension includes the addition of 8 new instructions as well as an Indexed Addressing mode. This feature, which can be activated in the gadget’s configurations, aims to improve the performance of re-entrant applications built in high-level languages like C.
When set to PWM mode, this module has 1, 2, or 4 modulated outputs that can be used to operate half-bridge and full-bridge drivers, respectively. Additional characteristics include auto-shutdown, which deactivates PWM outputs when an interrupt, or other select condition occurs; auto-restart, which enables outputs to be reactivated when the condition that caused their deactivation has been resolved.
This serial communication module is capable of regular RS-232 operation and includes support for the LIN bus protocol. Additional improvements consist of an automatic baud rate detection system and a 16-bit Baud Rate Generator, both of which contribute to an enhanced level of resolution. The EUSART ensures that applications communicating with the outside world operate consistently even when they don’t require an external crystal when the microcontroller uses the internal oscillator block.
This module includes programmable acquisition time, which enables a channel to be chosen and a conversion to be started without waiting for a sample period. As a result, code overhead can be reduced.
This improved version features a 16-bit prescaler, which makes it possible to have a longer time-out range while maintaining stability regardless of the operating voltage or temperature.
When the PRI IDLE mode is active, the primary oscillator is allowed to keep running continuously. When in any of the other power-saving modes, the OSC1-pin oscillator is not allowed to run. The oscillator’s OSC1 (and OSC2 if it’s being used) pin will cease to cycle. The Timer1 oscillator is active and supplies the device clock in the secondary clock modes (SEC RUN and SEC IDLE). If Timer1 or Timer3 need to be clocked, the Timer1 oscillator can operate in either of the power-saving modes. When the device operates in internal oscillator mode (RC RUN or RC IDLE), the internal oscillator block generates the device’s clock. Regardless of the power managed mode, the 31 kHz INTRC output can be utilized directly to provide the clock and may be enabled to offer a variety of specialized functions.
It is possible to divide the 8 MHz INTOSC output down using the postscaler, or use it as-is to clock the device. If the clock is provided from the INTRC output, the INTOSC output will be deactivated. When the Sleep mode is activated, all timekeeping mechanisms are disabled. Sleep mode reduces power usage to its minimum since transistor switching currents are eliminated (only leakage currents). Increasing Sleep current consumption enables any on-chip function that will activate during Sleep. For the WDT to function, the INTRC is essential. Possible use of the Timer1 oscillator in conjunction with a RealTime Clock. It is possible that other functionality is active that does not depend on a device clock source (i.e., MSSP slave, PSP, INTx pins and others)
In conclusion, the PIC18F2520-I/SP is a capable microcontroller that may be used for various applications.
