Comparison Between ATmega48PA, ATmega88PA, ATmega168PA and ATmega328P
architecture is more code efficient while achieving throughputs up to ten times faster than con-
ventional CISC microcontrollers.
The ATmega48PA/88PA/168PA/328P provides the following features: 4/8/16/32K 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 work-
ing 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 programmable
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 Inter-
face, 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 inter-
rupt 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 Reduc-
tion 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.
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 ATmega48PA/88PA/168PA/328P is a powerful microcontroller that
provides a highly flexible and cost effective solution to many embedded control applications.
The ATmega48PA/88PA/168PA/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 ATmega48PA, ATmega88PA, ATmega168PA and ATmega328P differ only in memory
sizes, boot loader support, and interrupt vector sizes.
ory and interrupt vector sizes for the three devices.
Table 2-1.
ATmega88PA, ATmega168PA and ATmega328P support a real Read-While-Write Self-Pro-
gramming mechanism. There is a separate Boot Loader Section, and the SPM instruction can
only execute from there. In ATmega48PA, there is no Read-While-Write support and no sepa-
rate Boot Loader Section. The SPM instruction can execute from the entire Flash.
