| CPU Speed | 16 MIPS |
How memory is mapped in AVR?
AVR microcontrollers are built using a modified Harvard Architecture. This means the Flash Program Memory space is on a separate address bus than the Static Random Access Memory (SRAM). There are two data bus, one that can access all data and the In/Out data bus with limited access to a small section of memory.
What atmega 16?
ATmega16 is an 8-bit high performance microcontroller from the Atmel’s Mega AVR family. Atmega16 is a 40 pin microcontroller based on enhanced RISC (Reduced Instruction Set Computing) architecture with 131 powerful instructions. It has a 16 KB programmable flash memory, static RAM of 1 KB and EEPROM of 512 Bytes.
What is the difference between Atmega16 and ATmega32?
ATmega32 is very much similar to ATmega16 microcontroller with certain differences which are discussed below. ATmega32 is an 8-bit high performance microcontroller of Atmel’s Mega AVR family. Atmega32 is based on RISC (Reduced Instruction Set Computing) architecture with 131 powerful instructions.
What are different types of memory available in your AVR device?
There are three types of memory in the AVR architecture:
- Program Memory.
- Data Memory.
- EEPROM.
How do you program ATMega 16?
Step5: Building and Uploading Sketch into Atmega16
- Save the main.
- Connect one LED in the PORTA0 pin of Atmega16 as in the picture above.
- Go to “Build” and then choose “Build Blink”.
- If program is correct then you won’t find any errors and you will get the message as below.
What is the maximum operating frequency of ATMega 16?
16MHz
Atmega16 can work on a maximum frequency of 16MHz.
What is the difference between ATmega16 and ATmega16A?
The ATmega16A is a functionally identical, drop-in replacement for the ATmega16. All devices are subject to the same qualification process and same set of production tests, but as the manufacturing process is not the same some electrical characteristics differ. ATmega16 and ATmega16A have separate datasheets.
