AVR closest to PIC16F684
The ATTINY2313 comes real close to meeting your needs for hardware I2C(TWI) and SPI - also very low cost. However, even though this processor supports both of these functions with...

AVR closest to PIC16F684
Your closest match from Atmel is an ATTINY24V. Both have 2K flash and 128 bytes SRAM. The PIC has 256 bytes of EEPROM while the TINY24 has 128 bytes of EEPROM. Both have timers,...

Is this the best way to measure PWM?
Normally, the frequency of a PWM signal doesn't change - at least not intentionally. If the frequency changes at all, it will be a slow change due to oscillator drift. You may be...

PWM Sanity Check
What sort of IR protocol are you planning to run ? I don't know of any "standard" IR protocol that uses PWM to encode data. Normally, the IR transmitter sends data bits that are...

avr bootloader vs avr without bootloader
We test our products (including products with AVR micros) according to numerous standards, one of which is the IEC ESD standard 61000-4-2. Typically, we test at a 16KV air-...

avr bootloader vs avr without bootloader
Quote:Any bootloader does this because it requires the flash runtime self programming being enabled permanently. While the self programming is enabled, a software/hardware glitch...

avr bootloader vs avr without bootloader
Quote:Regardless of a particular MCU model/make, a bootloader is just another way to screw up a working system at a customer's place. That's exactly what a poorly designed...

Any possible way to program via twi?
It can certainly be done with a TWI based bootloader. Once the bootloader has been programmed into the micro with ISP, then all updates can be accomplished with the bootloader....
