Atmel ATMEGA 16A
U5
Winbond 25X16AVS1G (SPI Flash 16Mbit)
U1
W - Winbond 25X - SPI Flash 16 - 16Mbit / 2M-byte (Uniform 4Kbyte sectors/64Kbyte blocks) AVS1G - 100MHz (200Mbits/sec)
datasheet: W25X16A.pdf (1.3 MB)
Note: can use Bus Ninja or Bus Pirate and FlashROM - ISP is possible, so long as no other devices on the SPI bus are trying to access the device (in that case, you might want to cut Vcc to the FPGA or the regulator for it).
