Author's note: Interestingly enough, the chip I imaged (brand new from Digikey, so presumably authentic) was labeled DRV2604 on the top metal layer, but 2605 on the top of the package. The only difference seems to be whether waveform data is stored in ROM or SRAM... maybe just a fuse difference? | Author's note: Interestingly enough, the chip I imaged (brand new from Digikey, so presumably authentic) was labeled DRV2604 on the top metal layer, but 2605 on the top of the package.

| Top metal pitch looks like ~600nm. Maybe 180nm tech? |
