Section 1 Introduction ™ The STK594 board is a top module designed to add AT94K FPSLIC support to the STK500 development board. With this board the STK500 is extended to support all cur- rent AT94K FPSLIC devices in a single development environment. The STK594 includes connectors, jumpers and hardware allowing full utilization of the new features of the FPSLIC family, see Figure 1-1. This user guide acts as a general getting started guide as well as a complete technical reference for advanced us

Using the STK594 Top Module Figure 2-1. Connecting the STK594 to the STK500 Board Note: Connecting the STK594 with the wrong orientation may damage the boards. Note: Do not mount the STK594 at the same time an AVR is mounted on the STK500 board. 2.2 PORT Since the AT94K devices have additional ports not available on the STK500, these ports are located on the STK594 board. The STK594 ports have the same pinout and func- Connectors tionality as the ports on the STK500 board. Since Port A to Port D

Using the STK594 Top Module ® 2.3 Programmingthe The FPSLIC configuration process involves configuring the FPGA, the AVR program code and the FPSLIC data memory. This configuration requires a single bitstream that AT94K Devices configures the FPGA, the embedded AVR Program SRAM and the FPSLIC Data SRAM. The combined bitstream is automatically generated by the Bitstream Generator, a System Designer software utility. After a reset and the internal clearing of the configuration data, the FPSLIC dev

Using the STK594 Top Module 2.5 TOSC Switch The AT94K device provides dedicated I/O pins for TOSC1 and TOSC2, rather than sharing with the general purpose I/O pins. The TOSC switch selects whether or not the 32 kHz crystal is connected to the pins of the device. Figure 2-5 shows a simplified block schematic on how this is implemented. Figure 2-5. TOSC Block Schematic FPSLIC 32 kHz TOSC2 TOSC1 TOSC Switch 2.6 Universal Unlike traditional AVR microcontrollers, the AT94K device provides the option

Using the STK594 Top Module 2.9 Split Power The AT94K FPSLIC devices exist in two different variations, the AL and AX. The AL variation is a 3.3V device manufactured on a 0.35µ process, while the AX variation has Supply Support a 1.8V core manufactured on a 0.18µ process. The primary difference between the two variations, is that the AX device requires a split power supply, as the I/Os are still pow- ered from a 3.3V supply, while the core operates at 1.8V. The STK594 supports both AT94K variati
