The SST34HF16x1A and SST34HF1681 ComboMemory devices integrate a 1M x16 CMOS flash memory bank with either a 128K x16, 256K x16, or 512K x16 CMOS SRAM memory bank in a multi-chip package (MCP). These devices are fabricated using SST’s proprietary, high-performance CMOS SuperFlash technology incorporating the split-gate cell design and thick oxide tunneling i.
• Flash Organization: 1M x16
• Dual-Bank Architecture for Concurrent Read/Write Operation
– 16 Mbit: 12 Mbit + 4 Mbit
• SRAM Organization:
– 2 Mbit: 128K x16
– 4 Mbit: 256K x16
– 8 Mbit: 512K x16
• Single 2.7-3.3V Read and Write Operations
• Superior Reliability
– Endurance: 100,000 Cycles (typical)
– Greater than 100 years Data Retention
• Low Power Consumption:
– Active Current: 25 mA (typical)
– Standby Current: 20 µA (typical)
• Hardware Sector Protection (WP#)
– Protects 4 outer most sectors (4 KWord) in the larger bank by holding WP# low and unprotects by holding WP# high
• Hardware Res.
