The PIC17LC43T-08/L is a highly integrated 8-bit microcontroller from Microchip Technology, with a PIC17LC family architecture and program memory that consists of 4,000 bytes of full-speed Flash memory. The on board peripheral set of the PIC17LC43T-08/L includes a high resolution 10-bit Analog-to-Digital Converter (ADC) core, a standard 10-bit Pulse-Width Modulation (PWM) module, a pair of Universal Synchronous/Asynchronous Receiver/Transmitters (USART/SCI), a pair of comparators, a watchdog timer (WDT), and a master synchronous serial port (MSSP).

The PIC17LC43T-08/L is widely used in embedded systems and is part of a complete microcontroller family, which includes versions with up to 32kB of on board Flash memory. This makes the PIC17LC43T-08/L ideal for applications such as remote control systems, lighting control, motor control and automotive systems. This microcontroller is also well-suited for applications requiring low-noise analog functions and high accuracy digital signal processing.

The PIC17LC43T-08/L microcontroller is based on the PIC17LC family architecture, which features a RISC-like instruction set and a Harvard bus structure. The architecture of the PIC17LC43T-08/L simplifies programming and increases system performance by providing a set of instructions and an on board stack pointer register. The on board Flash memory of the PIC17LC43T-08/L can be programmed using the low-cost Microchip PICkit 2 programmer. The programmer allows users to start development quickly by providing an easy-to-use interface and a number of development tools.

The PIC17LC43T-08/L integrates a 10-bit ADC to enable accurate analog-to-digital conversion of voltages of up to 5V. The ADC features 8 digital input pins (AN0 - AN7), which can be configured for use in a wide variety of control systems. The ADC can be programmed to make use of the on board USART modules for programming and debugging, or it can be operated autonomously. It also includes a Digital-to-Analog Converter (DAC) module, which converts digital samples into analog signals.

The PIC17LC43T-08/L comes with a pair of Universal Synchronous/Asynchronous Receiver/Transmitters (USART or SCI) to provide full-duplex asynchronous communications between the microcontroller and other devices for communication, programming and debugging. The USARTs can be used for low-speed communications at baud rates of up to 38.4kbps. The USARTs are compatible with standard serial protocols such as RS232, RS485 and SPI.

The PIC17LC43T-08/L integrates two PWM moudules, each with four configurable PWM output channels. These PWM modules can be used for generating pulse width modulated signals for controlling motors, lamps and other AC and DC loads. The PWM outputs can be configured to generate pulses of up to 1000Hz. The PWM modules can also be used to generate signals for interrupt servicing.

In addition, the PIC17LC43T-08/L also includes a Master Synchronous Serial Port (MSSP) module, which supports both synchronous serial communications and the I2C protocol. The serial port is designed for communication and programming with microcontrollers, EEPROMs, real-time clocks, and other peripheral devices. The MSSP module can be programmed to serve as either an I2C master, an I2C slave, an SPI master or an SPI slave.

Finally, the PIC17LC43T-08/L also features an integrated watchdog timer (WDT), which can be initialized to a user specified value and then generate an interrupt when the timer has expired. This timer can be used to detect system errors or abnormal conditions, in order to allow the microcontroller to take appropriate corrective action.

In conclusion, the PIC17LC43T-08/L is a highly integrated 8-bit microcontroller from Microchip Technology, ideal for embedded applications such as remote control systems, lighting control, motor control and automotive systems. The microcontroller has a RISC-like instruction set, a Harvard bus structure and a set of peripherals that includes a 10-bit ADC core, a standard 10-bit PWM module, a pair of USARTs, a pair of comparators, a watchdog timer, and a master synchronous serial port.
