Product Summary

The SST32HF3281-70-4E-LS is a CMOS flash memory bank with a CMOS SRAM memory bank in a Multi-Chip Package (MCP), manufactured with SSTs proprietary, high performance SuperFlash technology. The SST32HF3281-70-4E-LS uses a PseudoSRAM. The SST32HF16x1C/32x1C devices use standard SRAM. The SST32HF3281-70-4E-LS consists of two independent memory banks with respective bank enable signals. The Flash and SRAM memory banks are superimposed in the same memory address space.
