The STK501
board is a top module designed to add ATmega103(L)
and ATmega128(L)support to the STK500 development
board from Atmel Corporation.
With this board the STK500 is extended to support
all current AVR devices in a single development
environment.
The STK501 includes connectors, jumpers and hardware
allowing full utilization of the new features of
the ATmega128(L) while the Zero Insertion Force
(ZIF) socket allows easy use of TQFP packages for
prototyping.
In addition to adding support for new devices, it
also adds new support for peripherals previously
not supported by the STK500. An additional RS-232
port and external SRAM interface are09/01 among
the new features. Devices with dual UART or XRAM
interface can all take advantage of the new resources
on the STK501 board.
Connecting the STK501 to the STK500 Starter Kit

The STK501 should be connected to the STK500 expansion
header 0 and 1. It is important that the top module is
connected in the correct orientation as shown in picture.
The EXPAND0 written on the STK501 top module should match
the EXPAND0 written beside the expansion header on the
STK500 board.
Note: Connecting the STK501 with wrong orientation may
damage the board.
Placing an ATmega103(L) or ATmega128(L) on the
STK500
The STK501 contains both a ZIF socket, and the pinout
for a TQFP package; which allows an easy way of soldering
an emulator adapter directly into the STK501. Care should
be taken so that the device (or adapter) is mounted with
the correct orientation.
Caution: Do
not mount an ATmega103(L) or ATmega128(L) on the STK501
at the same time as an AVR is mounted on the STK500 board.
