ATmega48P/88P/168P
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 con-
ventional CISC microcontrollers.
The ATmega48P/88P/168P provides the following features: 4K/8K/16Kbytes of In-System Pro-
grammable Flash with Read-While-Write capabilities, 256/512/512bytes EEPROM,
512/1K/1Kbytes 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 pro-
grammable 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 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 dur-
ing 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.
Atmel offers the QTouch library for embedding capacitive touch buttons, sliders and wheels
functionality into AVR microcontrollers. The patented charge-transfer signal acquisition offers
robust sensing and includes fully debounced reporting of touch keys and includes Adjacent Key
Suppression (AKS) technology for unambiguous detection of key events. The easy-to-use
QTouch Suite toolchain allows you to explore, develop and debug your own touch applications.
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 ATmega48P/88P/168P is a powerful microcontroller that provides a
highly flexible and cost effective solution to many embedded control applications.
The ATmega48P/88P/168P AVR is supported with a full suite of program and system develop-
ment tools including: C Compilers, Macro Assemblers, Program Debugger/Simulators, In-Circuit
Emulators, and Evaluation kits.
