Comparison Between Processors
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 con-
ventional CISC microcontrollers.
The ATmega48A/48PA/88A/88PA/168A/168PA/328/328P provides the following features:
4K/8K bytes of In-System Programmable Flash with Read-While-Write capabilities,
256/512/512/1K bytes EEPROM, 512/1K/1K/2K bytes SRAM, 23 general purpose I/O lines, 32
general purpose working registers, three flexible Timer/Counters with compare modes, internal
and external interrupts, a serial programmable USART, a byte-oriented 2-wire Serial Interface,
an SPI serial port, a 6-channel 10-bit ADC (8 channels in TQFP and QFN/MLF packages), a pro-
grammable Watchdog Timer with internal Oscillator, and five software selectable power saving
modes. The Idle mode stops the CPU while allowing the SRAM, Timer/Counters, USART, 2-wire
Serial Interface, 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 com-
bined with low power consumption.
The device is manufactured using Atmel’s high density non-volatile memory technology. The
On-chip ISP Flash allows the program memory to be reprogrammed In-System through an SPI
serial interface, by a conventional non-volatile memory programmer, or by an On-chip Boot pro-
gram 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 Read-While-Write
operation. By combining an 8-bit RISC CPU with In-System Self-Programmable Flash on a
monolithic chip, the Atmel ATmega48A/48PA/88A/88PA/168A/168PA/328/328P is a powerful
microcontroller that provides a highly flexible and cost effective solution to many embedded con-
trol applications.
The ATmega48A/48PA/88A/88PA/168A/168PA/328/328P AVR 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.
The ATmega48A/48PA/88A/88PA/168A/168PA/328/328P differ only in memory sizes, boot
loader support, and interrupt vector sizes.
