SST32HF1681 - SST

SST32HF1681 (SST32HFxxx1) Multi-Purpose Flash Plus + SRAM ComboMemory

The SST32HFx1/x1C ComboMemory devices integrate a CMOS flash memory bank with a CMOS SRAM memory bank in a Multi-Chip Package (MCP), manufactured with SST’s proprietary, high performance SuperFlash technology. The SST32HF16x1/32x1 devices use a PseudoSRAM. The SST32HF16x1C/32x1C devices use standard SRAM. Featuring high performance Word-Program, the flash me.
