Are there multiple revisions of the ADRF6755 chip? When I checked revision code across multiple chips on few chips it shows 0x04 and on few it shows 0x06. Please gives details on which all revision code are possible.
Yes there are multiple revisions but all except revision code 4 are experiments / modifications that were never released. The only released version is revision code 4.
A couple of questions:
1. Did you purchase these or were they pre release samples?
2. Can you send me the all the data etched on the top of the package for both revision code versions.
These are purchased ADRF6755 chips. Data etched on the top of the package are
1) ADRF 6755 ACPZ #1421 2884550.1
I have 15 chips of this package, on some chips I get revision code as 0x04 and on few 0x06.
ACPZ #1413 2841056.1 I have only one chip of this package, on which I revision code is 0x04.
I have traced the assembly lot number (2884550.1) on our system and it tracks back to the correct mask set, etc. All these parts should read back revision code 04.
Is the readback consistent? Do you always readback 04 on the same parts and 06 on the same parts. Is your SPI readback consistent and working correctly?
Is it possible to send me a 06 part so that I can examine the die? Address is
