Description
ATmega169 ATmega169 is an ultra low power AVR 8-bit RISC microcontroller. It includes 16K byte
Self-programming Flash Program memory, 1K byte SRAM, 512 byte EEPROM, and 8-
channel 10-bit A/D converter, JTAG interface for On-chip Debugging and 4 X 25 Seg-
ment LCD driver. It can do up to 1 MIPS throughput at 1 MHz for ATmega169V, or 4
MIPS throughput at 4 MHz for the ATmega169L.
The ATmega169 is an excellent choice for low power applications that require user
interaction (LCD + keyboard) and the possibility to interface analog sensors etc.

See ATmega169 data sheet for more information.
STK502 The STK502 board is a top module designed to add ATmega169 support to the STK500
development board from Atmel.
STK502 includes connectors and hardware allowing full utilization of the new features of
the ATmega169 including an LCD display, while the Zero Insertion Force (ZIF) socket
allows easy use of TQFP packages for prototyping.
