Part Datasheet Audit Part identification
  • Manufacturer: Integrated Silicon Solution, Inc. (ISSI)
  • Manufacturer part number: IS21TF32G-JCLI
  • Function: 32 GB (256 Gbit) managed TLC NAND flash with eMMC 5.1 interface
  • Official datasheet: https://www.issi.com/WW/pdf/21-22TF16G-32G-64G-128G.pdf
  • Package: 153-ball VFBGA/FBGA, ordering code C
  • Temperature grade: Industrial, -40 °C to +85 °C
  • RoHS code: L
The Datasheet URL property was already populated with the official ISSI PDF, so no URL mutation was required.
Key specifications Metadata review Correct / consistent
  • MPN is exactly IS21TF32G-JCLI.
  • Manufacturer name identifies ISSI.
  • Description correctly states NAND flash, 256 Gbit, eMMC, 200 MHz, and 153-VFBGA dimensions.

Completed the datasheet audit and symbol reorganization. All 153 ball mappings were preserved; Pin Group was removed, and every terminal now has a balanced Left/Right orientation, functional section, and unique order with power first and grounds last.
Key issues flagged: incorrect internal AND classification, unspecified electrical pin types, and missing pin descriptions. Full results: Part Datasheet Audit.
