ATMEGA1284P-MU Block Diagram

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

The AVR core integrates a comprehensive set of instructions with 32 versatile working registers. Each of these registers is directly linked to the Arithmetic Logic Unit (ALU), enabling the simultaneous access of two independent registers in a single instruction, executed within one clock cycle. This unique architecture not only enhances code efficiency but also achieves throughputs up to ten times higher compared to traditional CISC microcontrollers.

Product comparison

Differences between ATmega164A, ATmega164PA, ATmega324A, ATmega324PA, ATmega644A, ATmega644PA, ATmega1284 and ATmega1284P，the ATmega164A/164PA/324A/324PA/644A/644PA/1284/1284P share the same features:

The ATmega164A/164PA/324A/324PA/644A/644PA/1284/1284P provide the following features:

16/32/64/128Kbytes of In-System Programmable Flash with Read-While-Write capabilities, 512/1K/2K/4Kbytes EEPROM, 1/2/4/16Kbytes SRAM, 32 general purpose /O lines, 32 general purpose working registers, Real Time Counter (RTC), three (four for ATmega1284/1284P) flexible Timer/Counters with compare modes and PWM, 2 USARTs, a byte oriented two-wire Serial Interface, a 8-channel, 10-bit ADC with optional differential input stage with programmable gain, programmable Watchdog Timer with Internal Oscillator, an SPI serial port, IEEE std. 1149.1 compliant JTAG test interface, also used for accessing the On-chip Debug system and programming and six software selectable power saving modes. The idle mode stops the CPU while allowing the SRAM, Timer/Counters, SPI port, and interrupt system to continue functioning. The Power-down mode saves the register contents but freezes the Oscillator, disabling all other chip functions until the next interrupt or Hardware Reset. In Power-save mode, the asynchronous timer continues to run, allowing the user to maintain a timer base while the rest of the device is sleeping. The ADC Noise Reduction mode stops the CPU and all I/O modules except Asynchronous Timer and ADC, to minimize switching noise during ADC conversions. In Standby mode, the Crystal/Resonator Oscillator is running while the rest of the device is sleeping. This allows very fast start-up combined with low power consumption. In Extended Standby mode, both the main Oscillatorand the Asynchronous Timer continue to run.

The device is manufactured using the high-density nonvolatile memory technology. The On-chip ISP Flash allows the program memory to be reprogrammed in-system through an SPI serial interface, by a conventional nonvolatile memory programmer, or by an On-chip Boot program running on the AVR core. The boot program can use any interface to download the application program in the application Flash memory. Software in the boot Flash section will continue to run while the Application Flash section is updated, providing true Reading-While-Writing operation. By combining an 8-bit RISC CPU with In-System Self-Programmable Flash on a monolithic chip, the ATmega164A/164PA/324A/324PA/644A/644PA/1284/1284P is a powerful microcontroller that provides a highly flexible and cost effective solution to many embedded control applications.

The ATmega164A/164PA/324A/324PA/644A/644PA/1284/1284P is supported with a full suite of program and system development tools including: C compilers, macro assemblers, program debugger/simulators, in-circuit emulators, and evaluation kits.
