The PIC18F4553-I/PT is an 8-bit embedded microcontroller that is classified as a 50-pin version and built on the enhanced version of PIC18 Longterm Platform. It is designed with a powerful 32-bit processor to cost-effectively meet low-power, low-cost, and convenience applications.

The PIC18F4553-I/PT is mostly used in RF transmission, automotive applications, communications systems, security starters, network and automotive in-cabin applications such as infotainment, LED lighting applications and much more. It incorporates analog-to-digital converters (ADC) and digital-to-analog converters (DAC) which helps the device to simulate the electrical signals.

The PIC18F4553-I/PT microcontroller is equipped with flash memory, RAM, EEPROM, four Timers/Counters, a Capture/Compare/PWM module and several communication interfaces such as USART, SPI, I2C, CAN, USB and LIN. It also includes Analog comparator, external interrupt and wake-up on change. This device integrates 256 bytes of RAM, 4096 bytes of EEPROM and 14K bytes of Flash memory.

The device provides multiple low-power modes. The Sleep-Enhanced Power-saving (SEPST_) mode allows the device to retain selected registers, RAM and peripherals in a low-power state. This device also features an Enhanced Halt (HLT_) mode which provides up to 50% lower consumption than the normal Halt mode.

The PIC18F4553-I/PT microcontroller requires an external clock input for its system operation and it has an internal 8MHz oscillator for clock source with no external components. This internal oscillator provides the device clock source in a range of 7.37MHz to 8.19MHz.

In terms of its operating voltage, the PIC18F4553-I/PT microcontroller can operate between 2.0V to 5.5V and it has an operating temperature of -40°C to +85°C. The device architecture includes three-level pipeline and a Harvard architecture that allows simultaneous memory read and write.

The PIC18F4553 microcontroller has an in-built Enhanced Capture/Compare/PWM module which is used for time-centric operations such as timers and counters. This module can be used in different operating modes such as the Output mode, Compare mode and the Capture mode.

The Output mode uses the Capture/Compare/PWM module to generate PWM signals from the output pins with certain frequency and different duty-cycle. The Compare mode uses the unit to compare values stored in the Capture/Compare registers, with the value in the Timer register that is being incremented for every clock pulse. The Capture mode uses this module to capture the 16-bit TMR0 value from the Timer register and puts it in the Capture/Compare register, depending on a trigger event.

The PIC18F4553 microcontroller also implements two flexible linear QE and two dual-input locks as standard protection circuits. These are used to control access to the Flash memory and thus prevent illegal users from gaining access to the controller’s memory resources.

The device is typically programmed using PIC-LITE IDE, C18, Dakota and ICD3 which comes with a USB 2.0 communications link to support high-speed data transfers. The device also supports a variety of development tools and programming languages such as C++ and Assembly language.

In summary, the PIC18F4553-I/PT microcontroller is a highly integrated 8-bit embedded microcontroller system that is built using an enhanced version of the PIC18 Longterm Platform. It is capable of providing multiple low-power modes which enable it to perform efficient operations without needing to sacrifice performance. This controller is designed with a powerful 32-bit processor to meet low-power, low-cost, and convenience applications such as RF transmission, automotive applications, communications systems, and LED lighting applications.
