Description
®
The Atmel ATmega164P is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC
architecture. By executing powerful instructions in a single clock cycle, the ATmega164P achieves
throughputs close to 1MIPS per MHz. This empowers system designer to optimize the device for power
consumption versus processing speed.
®
The Atmel 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 a 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 ATmega164P provides the following features: 16Kbytes of In-System Programmable Flash with
Read-While-Write capabilities, 512bytes EEPROM, 1Kbytes SRAM, 32 general purpose I/O lines, 32
general purpose working registers, Real Time Counter (RTC), three flexible Timer/Counters with compare
modes and PWM, two serial programmable USARTs , one byte-oriented 2-wire Serial Interface (I2C), a 8-
channel 10-bit ADC with optional differential input stage with programmable gain, a 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 oscillator and the asynchronous timer continue to run.
®
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 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 Read-While-Write operation. By combining an 8-bit RISC CPU with In-System
Self-Programmable Flash on a monolithic chip, the Atmel ATmega164P is a powerful microcontroller that
provides a highly flexible and cost effective solution to many embedded control applications.
The ATmega164P 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.

Resources
A comprehensive set of development tools, application notes, and datasheets are available for download
on http://www.atmel.com/avr.

Data Retention
Reliability Qualification results show that the projected data retention failure rate is much less than 1 PPM
over 20 years at 85°C or 100 years at 25°C.
About Code Examples
This documentation contains simple code examples that briefly show how to use various parts of the
device. These code examples assume that the part specific header file is included before compilation. Be
aware that not all C compiler vendors include bit definitions in the header files and interrupt handling in C
is compiler dependent. Confirm with the C compiler documentation for more details.
For I/O Registers located in extended I/O map, “IN”, “OUT”, “SBIS”, “SBIC”, “CBI”, and “SBI” instructions
must be replaced with instructions that allow access to extended I/O. Typically “LDS” and “STS”
combined with “SBRS”, “SBRC”, “SBR”, and “CBR”.

Capacitive Touch Sensing
7.4.1.
QTouch Library
The Atmel® QTouch® Library provides a simple to use solution to realize touch sensitive interfaces on
most Atmel AVR® microcontrollers. The QTouch Library includes support for the Atmel QTouch and Atmel
QMatrix® acquisition methods.
Touch sensing can be added to any application by linking the appropriate Atmel QTouch Library for the
AVR Microcontroller. This is done by using a simple set of APIs to define the touch channels and sensors,
and then calling the touch sensing API’s to retrieve the channel information and determine the touch
