The EE Electronics ESLA201A a USB-based, 8-channel logic analyzer with up to 24MHz sampling rate, and with 2 additional analog channels.
It is a clone of the CWAV USBee AX.
In sigrok, we use the open-source fx2lafw firmware for this logic analyzer.
See EE Electronics ESLA201A/Info for more detailed information on the device.
Hardware
- Cypress CY7C68013A — FX2 chip, 56 pins
- Atmel ATMLH113 — I2C EEPROM
- Texas Instruments TLC5510I — 8-bit ADC
- NXP 74HC4051D — 8-channel analog switch
- National LM358 — Low Power Dual Op-Amp
- ON Semiconductor MC33078 — Low Noise Dual Op-Amp
- Maxim ICL7650 — Chopper-Stabilized Op-Amp
Protocol
The USBee AX software controls the unit through a combination of command messages, and firmware patched for sample rates etc. downloaded before each capture. For this reason we have abandoned efforts to decode the protocol, and are working instead on fx2lafw — a replacement open source firmware for the device.
