Frequently Asked Questions
Q1: What does QGBA0A suffix stand for?
A: QG means halogen-free QFN package, BA is chip revision, 0A stands for fixed firmware and sorting standard.
Q2: What’s the advantage of UASP protocol?
A: UASP supports command queueing, faster read & write speed and lower CPU usage than traditional BOT protocol.
Q3: Does JMS578 work without external SPI flash?
A: It runs alone with built-in ROM. SPI flash is only needed for customized VID, PID and LED settings.
Q4: Can this chip auto spin down idle hard drives?
A: Yes, programmable auto sleep timer turns off HDD and enters low power mode after idle time.
Q5: What’s the max capacity of hard drives it supports?
A: It is compatible with HDD and SSD up to 18TB.
Q6: Is this IC suitable for bus-powered portable drives?
A: Yes, integrated LDO power regulators fit 5V bus-powered external storage enclosures.
Q7: What temperature range can this chip work in?
A: Operating temperature: 0°C to +70°C; storage temperature: -40°C ~ +125°C.
Q8: Does it support SSD TRIM function?
A: Yes, native TRIM pass-through keeps SSD performance and extends drive lifespan.
