Availability: Obsolete

Deviceimage

Summary

This device contains 32KB Flash memory, and contains a large range of peripherals. Among the more interesting features are: Self-programming memory (at target Vcc), JTAG interface, 8ch 10-bit ADC, internal calibrated RC Oscillator, Four PWM channels, hardware Multiplier, timers, external interrupts and a wide range of other peripherals as you can expect from a high performance AVR micro. The ATmega323 is pin compatible with the AT90S8535 and ATmega16, and is also available in a 5V version, the ATmega323
