AMS1117 3.3 1032 - Low Dropout Linear Regulator

U3 Datasheet: http://www.sltdigital.com/product/product_pdf/AMS1117.pdf / http://home1.cyber-labo.co.jp/board/goods/pdf/AMS1117.pdf
File:AMS1117 - SOT-223.png

(unreferenced 5pin IC : U4)

5-pin SOT5
A 47
pinout

Winbond 25X16AVS1G (SPI Flash 16Mbit)

8-pin TSSOP
Winbond 25X16A
SOIC-8 pinout

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).
