Arduino Microcontroller
- 2. Microcontroller | AVR The acronym of AVR stands for the initial AVR architecture designers: Alf-Egil Bogen & Vegard Wollen. Statically sometimes it is elongated as Advance Virtual RISC. Advance modified Harvard Architecture 8-Bit RISC single chip micro-controller On-Chip a mini system On chip memory : Flash, SRAM, EEPROM I/O & multitasking Ports
- 3. Microcontroller | AVR Architecture Harvard Architecture: Separate Instruction and Data paths. Faster and simultaneous access to data and instructions. Pipelining Concept RISC: Reduced Instruction Set computing rather than CISC i.e. x86 Simpler Instructions execute faster Optimized most used instruction.
- 4. Microcontroller | Program Memory Map FLASH: In system reprogrammable non-volatile program space storage is 32KB. A separate memory space partitioned for Boot Flash section. SRAM: Temporary values, stack of volatile type memory, memory size 2KB EEPROM: 1KB of space availability storage space for long-term.
- 5. Microcontroller | AVR Packages PDIP: Plastic dual-in-line Package abbreviated as PDIP is a chip-package with rectangular housing and two parallel rows of Electrical connecting pins. TQFP: Thin Quad Flat Package abbreviated as TQFP is a chip-package with quad housing with “gull wing” leads extending from each of four sides.
