EMBEDDED SYSTEM SELECTION 9 Field Programmable Gate Array (FPGA) USB Microcontroller EEPROM Product NameI/O PinsFPGACost EZ1CUSB128Altera Cyclone$199/$219 EZ1KUSB58Altera ACEX$169/$179/$189 EZ2USB58 Xilinx Spartan- II $169/$179/$189 XEM Xilinx Spartan 3 $ FPGA SELECTION

XEM

XEM Pro’s One of the cheapest Built in USB  FPGA interface High level of support and tools (SDK’s and API’s) Good number of I/O Pins Familiar with Xilinx Spartan 3 FPGA’s Con’s Hard to solder (easier than the other three) Has male-female connectors that attach to the holes Needs to be programmed at start Easy to reprogram with provided SDK (one line of code!)

EEPROM COMPARISON: PARALLEL OR SERIAL 12 Parallel Pro’s Easiest to write to Higher memory density Better AC performance Con’s Very large foot print (Size of 2 N bits requires N pins, for addressing, and other pins for power, select, etc) Higher power consumption Costly Series Pro’s Smaller footprint (only about 8 pins) Smaller power consumption (good if an onboard battery is used) Faster access time Cheaper Con’s More complexity involved in writing/reading data from EEPROM Conclusion: Series Two different kinds of serial, SPI and I 2 C

13 EEPROM COMPARISON: SPI OR I 2 C I2C Pro’s Easier to implement multiple devices on same bus Communicate with on- board infrequently used devices easily Con’s High complexity compared to SPI Half-duplex SPI Pro’s Faster Full-duplex Less overhead than I 2 C due to no addressing Con’s More devices requires more wires and more hardware Conclusion: SPI Component Selected: Spansion 8-Mbit SPI EEPROM

BACK UP SLIDES

Definition of Parallel EEPROM Typically has 8-bit data bus Address bus large enough to cover complete address range Ex addresses = 2 10 addresses, so 10 bits for a data bus To Write: Enable Write with Address Selected Disable Write when data is asserted on data pins To Read: Enable Read with Address Selected Read data asserted on data pins

Definition of Serial I 2 C 2 wire-input Serial Data (SDA) Serial Clock (SCL) Communication Process Master sends start condition Master sends unique 7-bit address of the slave Master sends read/write bit (0 – write, 1 – read) Receiver (Master when read, slave when write) sends “ACK”nowledgement Transmitter (Master when write, slave when read) transmits 1 byte Receiver sends ack (repeats till stop)
