Embedded - Microcontrollers

The LC87F5R96BVU-QIP-E is a single-chip 8-bit microcontroller designed for low-cost embedded applications. It is a member of the R8C/Tiny series of 8-bit microcontrollers from Renesas developed for low-end embedded systems and general-purpose applications. This microcontroller integrates 8-bit quartz timer, 8-bit general-purpose timers, one 10-bit ADC or two 8-bit ADCs, four 8-bit PWM output, 16-bit I/O, and 408 programmable I/O signals.

Application Field: The LC87F5R96BVU-QIP-E microcontroller is mainly used in the following areas:

• Industrial automation: light weight and simple control systems.
• Automotive applications: electric suspension systems and traction control.
• Audio systems: media players, and amplifiers.
• Consumer appliances: electric fans, washing machines, refrigerators, and air conditioners.
• Home automation: remote temperature and humidity sensors.
• Building automation: security systems, lighting, and HVAC systems.

Working Principle: The LC87F5R96BVU-QIP-E microcontroller has an architecture consisting of a CPU and multiple peripheral modules. The CPU is a 75MHz 8-bit CPU that supports instructions such as MOV (move) and LDI (load immediate data). It is connected to the peripherals by an internal bus and interrupts generated by the peripherals. The peripheral modules include timers, analog to digital converters (ADC), pulse width modulation (PWM) output, memory and serial communication.

The CPU executes instructions written in the form of the machine code. The code is stored in program memory and is executed sequentially. Each instruction typically consists of one or more bytes. The machine code is used to manipulate the data and system flags are set to indicate certain information such as interrupts and errors.

The LC87F5R96BVU-QIP-E microcontroller supports many different interfaces including I/O, UART, SPI, I2C, CAN, Ethernet, and USB. The controller can be connected to external devices such as displays, keyboards, sensors, motors and other peripherals. It has an input port for receiving analog signals and a dedicated LCD controller for driving LCD displays.

The microcontroller also supports debugging via a serial debugging port. This allows the programmer to monitor the program and trace execution. The programmers can also perform object-level debugging, such as monitoring register data as well as read and write areas in the memory.

In addition to its extensive peripherals, the LC87F5R96BVU-QIP-E has one of the smallest package sizes in the industry, making it ideal for embedded applications with space constraints. Its low power consumption and the ability to operate at up to 75MHz make it suitable for applications which require high processing power and low power consumption.
