ATMEGA324PA-AU - ATMEL Function Overview

The ATMEGA324PA-AU is a 8-bit high-performance AVR RISC-based Microcontroller Unit combines 32kB ISP flash memory with read-while-write capabilities, 1kB EEPROM, 2kB SRAM, 32 general purpose I/O lines, 32 general purpose working registers, a real time counter, three flexible timer/counters with compare modes and PWM, two USARTs, a byte oriented 2-wire serial interface, an 8-channel 10-bit A/D converter with optional differential input stage with programmable gain, programmable watchdog timer with internal oscillator, SPI serial port, a JTAG (IEEE 1149.1 compliant) test interface for on-chip debugging and programming and six software selectable power saving modes.
Device operates at 1.8 to 5.5V
Advanced RISC architecture
131 Powerful instructions
Fully static operation
Up to 20MIPS throughput at 20MHz
On-chip 2-cycle multiplier
High endurance non-volatile memory segments
Optional boot code section with independent lock bits
In-system programming by on-chip boot program
True Read-While-Write operation
An interrupt between step 5 and step 6 will make the write cycle fail, since the EEPROM Master Write Enable will time-out.
