SST SST32HF1622C
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
:● ComboMemories organized as: – SST32HF1622C: 1M x16 Flash + 128K x16 SRAM – SST32HF1642x: 1M x16 Flash + 256K x16 SRAM – SST32HF1682: 1M x16 Flash + 512K x16 SRAM – SST32HF3242x: 2M x16 Flash + 256K x16 SRAM – SST32HF3282: 2M x16 Flash + 512K x16 SRAM
● Single 2.7-3.3V Read and Write Operations
● Concurrent Operation – Read from or Write to SRAM while Erase/Program Flash
● Superior Reliability – Endurance: 100,000 Cycles (typical) – Greater than 100 years Data Retention
● Low Power Consumption: – Active Current: 15 mA (typical) for Flash or SRAM Read – Standby Current: - SST32HFx2: 60 µA (typical) - SST32HFx2C: 12 µA (typical)
● Flexible Erase Capability – Uniform 2 KWord sectors – Uniform 32 KWord size blocks
● Erase-Suspend/Erase-Resume Capabilities
● Security-ID Feature – SST: 128 bits; User: 128 bits
● Hardware Block-Protection/WP# Input Pin – Top Block-Protection (top 32 KWord)
● Fast Read Access Times: – Flash: 70 ns – SRAM: 70 ns
● Latched Address and Data for Flash
