Product Description
pSLC Mode eMMC 5.1 BGA153 16GB 19GB High Write Embedded Storage Memory Chip
Some embedded products cannot avoid writing constantly. Flight recorders, event loggers and production testers push far more write traffic than a consumer device, and a standard TLC flash cell simply runs out of usable program erase cycles too early. pSLC mode reconfigures each cell to store a single bit, lifting endurance dramatically and giving those write heavy designs a workable service life.
This pSLC mode eMMC 5.1 brings that benefit inside the standard BGA153 package and eMMC 5.1 HS400 interface. It is offered in 16GB and 19GB capacities, so a configured part still delivers a practical capacity for firmware, logs and buffered data while keeping the endurance that the application actually needs.
For teams that cannot accept a mid project change of storage, pSLC mode offers a simple reliability upgrade path. The same board, driver and footprint stay in place while the endurance budget grows to match a demanding write profile. We supply configuration notes and test data so the endurance benefit can be verified during your qualification stage before the design is frozen.

Advantages Of pSLC Mode Storage
- Far higher program erase cycles than the same NAND used in TLC mode.
- Better data retention for archive style logs that must survive storage at temperature.
- More predictable latency because fewer bits per cell simplifies read and write.
- Standard eMMC 5.1 HS400 interface keeps host software unchanged.
- BGA153 footprint allows a drop in replacement on existing boards.
- Available in 16GB and 19GB capacities to match your logging budget.
pSLC Mode eMMC 5.1 Questions
What does pSLC mode mean?
Each NAND cell is programmed to hold a single bit instead of three. The reduced density per cell makes the cell much easier to erase and reprogram, which raises the program erase cycle rating significantly.
How much capacity do I lose?
pSLC usually yields roughly one third of the source NAND capacity. We offer PG pSLC parts in 16GB and 19GB, so the resulting capacity still covers most logging and firmware requirements.
Is the interface still standard eMMC?
Yes. The part keeps the eMMC 5.1 HS400 interface and BGA153 package, so no host driver change is required.
Where is pSLC storage most useful?
It fits flight recorders, event loggers, production test equipment and any design where write traffic is high and long service life matters more than raw capacity.
Can you tune the configuration?
Yes. Tell us the endurance and capacity targets of your project and we will propose a suitable pSLC configuration with supporting test data.
PG delivers embedded flash from Shenzhen with CE, RoHS, ISO9001, AEC-Q100 and IATF16949 certified production. Endurance data and tuned pSLC configurations are available for your qualification programme.
