Overview
The ATmega162 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 ATmega162
achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize
power consumption versus processing speed.

2513KS–AVR–07/09
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 conventional CISC microcontrollers.
The ATmega162 provides the following features: 16K bytes of In-System Programmable Flash
with Read-While-Write capabilities, 512 bytes EEPROM, 1K bytes SRAM, an external memory
interface, 35 general purpose I/O lines, 32 general purpose working registers, a JTAG interface
for Boundary-scan, On-chip Debugging support and programming, four flexible Timer/Counters
with compare modes, internal and external interrupts, two serial programmable USARTs, a programmable Watchdog Timer with Internal Oscillator, an SPI serial port, and five 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. 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.
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 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 ATmega162 is a powerful microcontroller that provides a highly flexible and cost effective solution to many embedded control applications.
The ATmega162 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.
ATmega161 and
ATmega162
Compatibility
The ATmega162 is a highly complex microcontroller where the number of I/O locations supersedes the 64 I/O locations reserved in the AVR instruction set. To ensure back-ward
compatibility with the ATmega161, all I/O locations present in ATmega161 have the same locations in ATmega162. Some additional I/O locations are added in an Extended I/O space starting
from 0x60 to 0xFF, (i.e., in the ATmega162 internal RAM space). These locations can be
reached by using LD/LDS/LDD and ST/STS/STD instructions only, not by using IN and OUT
instructions. The relocation of the internal RAM space may still be a problem for ATmega161
users. Also, the increased number of Interrupt Vectors might be a problem if the code uses
absolute addresses. To solve these problems, an ATmega161 compatibility mode can be
selected by programming the fuse M161C. In this mode, none of the functions in the Extended
I/O space are in use, so the internal RAM is located as in ATmega161. Also, the Extended Interrupt Vec-tors are removed. The ATmega162 is 100% pin compatible with ATmega161, and can
replace the ATmega161 on current Printed Circuit Boards. However, the location of Fuse bits
and the electrical characteristics differs between the two devices.
ATmega161
Compatibility Mode
Programming the M161C will change the following functionality:

•
The extended I/O map will be configured as internal RAM once the M161C Fuse is
programmed.

•
The timed sequence for changing the Watchdog Time-out period is disabled. See “Timed
Sequences for Changing the Configuration of the Watchdog Timer” on page 56 for details.
•
The double buffering of the USART Receive Registers is disabled. See “AVR USART vs.
AVR UART – Compatibility” on page 168 for details.
•
Pin change interrupts are not supported (Control Registers are located in Extended I/O).
•
One 16 bits Timer/Counter (Timer/Counter1) only. Timer/Counter3 is not accessible.
Note that the shared UBRRHI Register in ATmega161 is split into two separate registers in
ATmega162, UBRR0H and UBRR1H. The location of these registers will not be affected by the
ATmega161 compatibility fuse.

Port A (PA7..PA0)
Port A is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The
Port A output buffers have symmetrical drive characteristics with both high sink and source
capability. When pins PA0 to PA7 are used as inputs and are externally pulled low, they will
source current if the internal pull-up resistors are activated. The Port A pins are tri-stated when a
reset condition becomes active, even if the clock is not running.
Port A also serves the functions of various special features of the ATmega162 as listed on page
72.
Port B (PB7..PB0)
Port B is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The
Port B output buffers have symmetrical drive characteristics with both high sink and source
capability. As inputs, Port B pins that are externally pulled low will source current if the pull-up
resistors are activated. The Port B pins are tri-stated when a reset condition becomes active,
even if the clock is not running.
Port B also serves the functions of various special features of the ATmega162 as listed on page
72.
Port C (PC7..PC0)
Port C is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The
Port C output buffers have symmetrical drive characteristics with both high sink and source
capability. As inputs, Port C pins that are externally pulled low will source current if the pull-up
resistors are activated. The Port C pins are tri-stated when a reset condition becomes active,
even if the clock is not running. If the JTAG interface is enabled, the pull-up resistors on pins
PC7(TDI), PC5(TMS) and PC4(TCK) will be activated even if a Reset occurs.
Port C also serves the functions of the JTAG interface and other special features of the
ATmega162 as listed on page 75.

Port D (PD7..PD0)
Port D is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The
Port D output buffers have symmetrical drive characteristics with both high sink and source
capability. As inputs, Port D pins that are externally pulled low will source current if the pull-up
resistors are activated. The Port D pins are tri-stated when a reset condition becomes active,
even if the clock is not running.
Port D also serves the functions of various special features of the ATmega162 as listed on page
78.
Port E(PE2..PE0)
Port E is an 3-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The
Port E output buffers have symmetrical drive characteristics with both high sink and source
capability. As inputs, Port E pins that are externally pulled low will source current if the pull-up
resistors are activated. The Port E pins are tri-stated when a reset condition becomes active,
even if the clock is not running.
Port E also serves the functions of various special features of the ATmega162 as listed on page
81.
RESET

1. When the OCDEN Fuse is unprogrammed, the OSCCAL Register is always accessed on this address. Refer to the debugger specific documentation for details on how to use the OCDR Register.
2. Refer to the USART description for details on how to access UBRRH and UCSRC.
3. For compatibility with future devices, reserved bits should be written to zero if accessed. Reserved I/O memory addresses
should never be written.
4. Some of the Status Flags are cleared by writing a logical one to them. Note that the CBI and SBI instructions will operate on
all bits in the I/O Register, writing a one back into any flag read as set, thus clearing the flag. The CBI and SBI instructions
work with registers 0x00 to 0x1F only.

Errata
The revision letter in this section refers to the revision of the ATmega162 device.
ATmega162, all
rev.
There are no errata for this revision of ATmega162. However, a proposal for solving problems
regarding the JTAG instruction IDCODE is presented below.
• IDCODE masks data from TDI input
• Reading EEPROM by using ST or STS to set EERE bit triggers unexpected interrupt request
• Interrupts may be lost when writing the timer register in asynchronous timer
1. IDCODE masks data from TDI input
The public but optional JTAG instruction IDCODE is not implemented correctly according to
IEEE1149.1; a logic one is scanned into the shift register instead of the TDI input while shifting the Device ID Register. Hence, captured data from the preceding devices in the
boundary scan chain are lost and replaced by all-ones, and data to succeeding devices are
replaced by all-ones during Update-DR.
If ATmega162 is the only device in the scan chain, the problem is not visible.
Problem Fix / Workaround
Select the Device ID Register of the ATmega162 (Either by issuing the IDCODE instruction
or by entering the Test-Logic-Reset state of the TAP controller) to read out the contents of
its Device ID Register and possibly data from succeeding devices of the scan chain. Note
that data to succeeding devices cannot be entered during this scan, but data to preceding
devices can. Issue the BYPASS instruction to the ATmega162 to select its Bypass Register
while reading the Device ID Registers of preceding devices of the boundary scan chain.
Never read data from succeeding devices in the boundary scan chain or upload data to the
succeeding devices while the Device ID Register is selected for the ATmega162. Note that
the IDCODE instruction is the default instruction selected by the Test-Logic-Reset state of
the TAP-controller.
Alternative Problem Fix / Workaround
If the Device IDs of all devices in the boundary scan chain must be captured simultaneously
(for instance if blind interrogation is used), the boundary scan chain can be connected in
such way that the ATmega162 is the first device in the chain. Update-DR will still not work
for the succeeding devices in the boundary scan chain as long as IDCODE is present in the
JTAG Instruction Register, but the Device ID registered cannot be uploaded in any case.
2. Reading EEPROM by using ST or STS to set EERE bit triggers unexpected interrupt
request.
Reading EEPROM by using the ST or STS command to set the EERE bit in the EECR register triggers an unexpected EEPROM interrupt request.
Problem Fix / Workaround
Always use OUT or SBI to set EERE in EECR.
3. Interrupts may be lost when writing the timer register in asynchronous timer
The interrupt will be lost if a timer register that is synchronous timer clock is written when the
asynchronous Timer/Counter register (TCNTx) is 0x00.
Problem Fix / Workaround
Always check that the asynchronous Timer/Counter register neither have the value 0xFF nor
0x00 before writing to the asynchronous Timer Control Register (TCCRx), asynchronous
Timer Counter Register (TCNTx), or asynchronous Output Compare Register (OCRx).
