PIN SUPPORT FOR
STK500
The STK501 board is an expansion module designed to add 64-pin support to the
Atmel®STK500 Development Board. The STK500 and STK501 expansion module
extends support to all current AVR®devices.
The STK501 includes connectors,
jumpers, and hardware allowing full
support for the new features on
ATmega103, ATmega64, and
ATmega128. The Zero Insertion Force
(ZIF) socket allows easy use of TQFP
packages. In addition to providing
support for new devices, the STK501
also adds support for peripherals
previously not supported by the
STK500. An additional RS-232 driver
and an XRAM interface are among the new features. Devices with dual UART or
XRAM interface can thus take advantage of the new resources on the STK501 board.

The STK501 board is a hardware expansion module for the STK500 Development
Board. The ZIF socket on the STK501 adds support for ATmega103, ATmega64, and
ATmega128 to the list of devices supported by the STK500. The STK500 supports
all megaAVR®, tinyAVR™, and classic AVR devices.
The STK500 board provides full programming and development support for the
ATmega103, ATmega64, and ATmega128. Additional ports and interfaces on the
STK500 have now been made available with the STK501. Among the new features are:
