Unlock Microcontroller ATMEGA2561V Heximal

We can Unlock Microcontroller ATMEGA2561V Heximal, please view the Microcontroller ATMEGA2561V features for your reference:

· Analog MUX can be turned off when setting ACME bit when Unlock Microcontroller

· TWI Data setup time can be too short

1. Analog MUX can be turned off when setting ACME bit

If the ACME (Analog Comparator Multiplexer Enabled) bit in ADCSRB is set while MUX3 in ADMUX is ‘1’ (ADMUX[3:0]=1xxx), all MUX’es are turned off until the ACME bit is cleared if Unlock Microcontroller.

Problem Fix/Workaround

Clear the MUX3 bit before setting the ACME bit.

2. TWI Data setup time can be too short

When running the device as a TWI slave with a system clock above 2MHz, the data setup time for the first bit after ACK may in some cases be too short. This may cause a false start or stop condition on the TWI line before Unlock Microcontroller.

Problem Fix/Workaround

Insert a delay between setting TWDR and TWCR.

· Analog MUX can be turned off when setting ACME bit

· TWI Data setup time can be too short after Unlock Microcontroller 

Typical values contained in this data sheet are based on simulations and characterization of other AVR microcontrollers manufactured on the same process technology when Unlock Microcontroller.

Min and Max values will be available after the device is characterized. The ATmega64 is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture if Unlock Microcontroller.

By executing powerful instructions in a single clock cycle, the ATmega64 achieves throughputs approaching 1 MIPS per MHz, allowing the system designer to optimize power consumption versus processing speed when Unlock Microcontroller.

The AVR core combines a rich instruction set with 32 general purpose working registers.

All the 32 registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two independent registers to be accessed in one single instruction executed in one clock cycle before Unlock Microcontroller.

The resulting architecture is more code efficient while achieving throughputs up to ten times faster than conventional CISC microcontrollers.
