FPGA bitstream: ST M25P10VP, 1Mbit SPI NOR flash (datasheet)
I²C EEPROM: None? (CY7C68013A I2C port wired to FPGA pins)
Bootstrap controller: Markings ground off, pinout could indicate a STCMCU 15F10x 8051-based MCU?
3.3V voltage regulator: unknown switching regulator (marked "IC5CJ" ?) + 150k/680k resistors pair
1.5V voltage regulator: unknown switching regulator (marked "IC5CJ" ?) + 160k/240k resistors pair
Channel input buffering: none, only simple resistor (510R) + TVS diode array protection (possibly Semtech SRV05)

Protocol¶

See Saleae_Logic16#Protocol.

Firmware¶

Actel variant This logic analyzer works with unmodified Saleae software. The Actel FPGA has on-chip flash storage, so it only requires an upload of Cypress FX2LP firmware in order to operate. Cyclone variant This logic analyzer works with unmodified Saleae software. The PCB contains an SPI flash chip, so it only requires an upload of Cypress FX2LP firmware in order to operate. 2015-01-08 and 2018 variants Only requires an upload of Cypress FX2LP firmware to operate. Open-source binaries from gregani work, but must be renamed to saleae-logic16-fx2.fw. It also requires a libsigrok more recent than 2014-08-22 to work (see bug #680). 2014-01-25 variant Seems to have the bitstream in internal flash, so it only requires an upload of Cypress FX2LP firmware in order to operate. This requires a libsigrok more recent than 2014-08-22 to work (see bug #680).

The firmware extraction steps are identical to steps for Saleae Logic16, however you only need to have saleae-logic16-fx2.fw installed.
