Microchip SST SuperFlash Gen 4 Automotive Memory Qualified for Production

On January 15, Silicon Storage Technology, a subsidiary of Microchip Technology Inc., and United Microelectronics Corporation announced the successful full qualification and production release of Microchip SST SuperFlash Gen 4 automotive memory. The solution is qualified to full automotive grade 1 capability on UMC’s 28HPC+ foundry process.
Microchip SST SuperFlash Gen 4 automotive memory for controllers
Microchip SST SuperFlash Gen 4 automotive memory was co-developed with UMC to address the rising performance and reliability needs of automotive controllers. The embedded non-volatile memory technology is engineered to support demanding vehicle environments while improving manufacturing efficiency on advanced 28nm platforms.
Performance and reliability highlights
The solution delivers strong technical metrics aligned with automotive requirements:

• AEC-Q100 Grade 1 compliance from −40°C to +150°C

• Fast read access below 12.5 ns

• Endurance exceeding 100K program/erase cycles

• Data retention beyond 10 years at 125°C

• Minimal ECC requirement limited to 1-bit

Manufacturing efficiency on UMC 28HPC+
Compared with other 28nm HKMG eFlash options, Microchip SST SuperFlash Gen 4 automotive memory significantly reduces additional mask steps. This approach lowers overall cost while improving yield and manufacturing efficiency, making it well suited for scalable automotive-grade system-on-chip designs.
