PRODUCT DESCRIPTION

The SST32HFx2/x2C 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 SST32HF16x2/32x2 devices use a PseudoSRAM. The SST32HF16x2C/3242C devices use standard SRAM.

FEATURES:
