Renesas Microcontroller Renesas is latest automotive microcontroller family that offers high performance feature with exceptionally low power consumption over a wide and versatile extend of items. This microcontroller offers rich functional security and embedded safety characteristics required for new and advanced automotive applications. The core structure of microcontroller CPU support high reliability and high performance requirements. The Renesas microcontroller offering low power, high performance, modest packages and the largest range of memory sizes combined together with characteristics rich peripherals. Renesas offers the most versatile microcontroller families in the world for example our RX family offers a many types devices with memory variants from 32K flash/4K RAM to an incredible 8M flash/512K RAM. The RX Family of 32-bit microcontrollers is a feature rich, general purpose MCU covering a wide range of embedded control applications with high speed connectivity, digital si

PIC Microcontroller                                                  PIC is a peripheral interface controller, developed by general instrument’s microelectronics, in the year of 1993. It is controlled by the software. They could be programmed to complete many task and control a generation line and many more. PIC microcontrollers are finding their way into new applications like smart phones, audio accessories, video gaming peripherals and advanced medical devices.             There are many PICs, started with PIC16F84 and PIC16C84. But these were the only affordable flash PICs. Microchip has recently introduced flash chips with types that are much more attractive, such as 16F628, 16F877 and 18F452. The 16F877 is around twice the price of the old 16F84, but has eight times the code size, much more RAM, much more I/O pins, a UART, A/D converter and a lot more. Features of PIC16F877 Core Features: ·          High-performance RISC CPU ·          Up to 8K x 14 words of FLASH program memory ·

8051 microcontrollers Available as word document for downloading at the end of the post   8051 microcontrollers This microcontroller is also called as “System on a chip” because it has all the features on a single chip. The Block Diagram of 8051 Microcontroller is as shown in Figure                                   Image  credit : EngineersGarage It use two different kinds of memory such as UV- EPROM, Flash and NV-RAM. Hence 8051 will not be seen in the part number even though it is the most popular member of the 8051 family AT89C51 (Variant of 8051 microcontroller) from Atmel Corporation 1 (‘C’ in the part number indicates  CMOS ). The flash memory can erase the contents within seconds which is best for fast growth. Therefore, 8751 is replaced by AT89C51 to eradicate the waiting time required to erase the contents and hence expedite the development time. To build up a microcontroller based system using AT89C51, it is essential to have ROM burner that supports flash memory.
