PRODUCT DESCRIPTION

The SST34HF16x1J ComboMemory devices integrate either a 1M x16 or 2M x8 CMOS flash memory bank with either a 256K x16, or 512K x16 CMOS pseudo SRAM (PSRAM) memory bank in a multi-chip package (MCP).

FEATURES:

? Flash Organization: 1M x16 or 2M x8

? Dual-Bank Architecture for Concurrent Read/Write Operation

– Bottom Sector Protection

– 16 Mbit: 12 Mbit + 4 Mbit

? PSRAM Organization:

– 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)

– PSRAM Standby Current: 40 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 Reset Pin (RST#)

– Resets the internal state machine to reading data array

? Byte Selection for Flash (CIOF pin)

– Selects 8-bit or 16-bit mode (56-ball package only)

? Sector-Erase Capability

– Uniform 2 KWord sectors

? Block-Erase Capability

– Uniform 32 KWord blocks

? Read Access Time

– Flash: 70 ns

– PSRAM: 70 ns

? Erase-Suspend / Erase-Resume Capabilities

? Security ID Feature

– SST: 128 bits

– User: 128 bits

? Latched Address and Data

? Fast Erase and Program (typical):

– Sector-Erase Time: 18 ms

– Block-Erase Time: 18 ms

– Chip-Erase Time: 35 ms

– Program Time: 7 μs

? Automatic Write Timing

– Internal VPP Generation

? End-of-Write Detection

– Toggle Bit

– Data# Polling

– Ready/Busy# pin

? CMOS I/O Compatibility

? JEDEC Standard Command Set

? Packages Available

– 56-ball LFBGA (8mm x 10mm)
