Description
ATmega161(L)
The ATmega161 is a low-power CMOS 8-bit microcontroller based on the AVR RISC
architecture. By executing powerful instructions in a single clock cycle, the ATmega161
achieves throughputs approaching 1 MIPS per MHz allowing the system designer to
optimize power consumption versus processing speed. 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 architec-
ture is more code-efficient while achieving throughputs up to ten times faster than
conventional CISC microcontrollers.
The ATmega161 provides the following features: 16K bytes of In-System or Self-
programmable Flash, 512 bytes EEPROM, 1K byte of SRAM, 35 general purpose I/O
lines, 32 general purpose working registers, Real-time Counter, three flexible
Timer/Counters with Compare modes, internal and external interrupts, two programma-
ble serial UARTs, programmable Watchdog Timer with internal Oscillator, an SPI serial
port and three 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 and SRAM contents but freezes
the Oscillator, disabling all other chip functions until the next External Interrupt or Hard-
ware Reset. In Power-save mode, the timer Oscillator continues to run, allowing the
user to maintain a timer base while the rest of the device is sleeping.
The device is manufactured using Atmel’s high-density non-volatile memory technology.
The On-chip Flash Program memory can be reprogrammed using the Self-programming
capability through the Boot Block and an ISP through the SPI port, or by using a conven-
tional non-volatile Memory programmer. By combining an enhanced RISC 8-bit CPU
with In-System Programmable Flash on a monolithic chip, the Atmel ATmega161 is a
powerful microcontroller that provides a highly flexible and cost-effective solution to
many embedded control applications.
The ATmega161 AVR is supported with a full suite of program and system development
tools including: C compilers, macro assemblers, program debugger/simulators, In-Cir-
cuit Emulators and evaluation kits.

Crystal Oscillator
XTAL1 and XTAL2 are input and output, respectively, of an inverting amplifier that can
be configured for use as an on-chip Oscillator, as shown in Figure 2. Either a quartz
crystal or a ceramic resonator may be used. To drive the device from an external clock
source, XTAL2 should be left unconnected while XTAL1 is driven as shown in Figure 3.
