1.5V voltage regulator: unknown switching regulator (marked "IC5CJ" ?) + 160k/240k resistors pair.3.3V voltage regulator: unknown switching regulator (marked "IC5CJ" ?) + 150k/680k resistors pair.Bootstrap controller: Markings ground off, pinout could indicate a STCMCU 15F10x 8051-based MCU?.I☬ EEPROM: None? (CY7C68013A I2C port wired to FPGA pins).USB interface chip: Markings sometimes ground off? Cypress CY7C68013A.FPGA: Markings ground off, but pinout and JTAG (IDCODE 0x020810dd) indicate an Altera Cyclone EP1C3T100.The bottom two channels are not GND, but SCK (sample clock out) and HCK (half of SCK out). The PCB is marked "Saleae Logic 16 mcupro 2014.1.25".
