SST88VP1107

The SST88VP1107 is a reliable, high-performance, singlepackage, managed memory subsystem for code and data storage that is easy to use. Designed for embedded applications including mobile phones and portable consumer electronics, this product provides an all-in-one memory solution through its unique capability to configure its various memory resources. Providing code storage (NOR), data storage (NAND), and system RAM (PSRAM) functions all on a single bus, the SST88VP1107 is well suited for manufacturers who need high density memory with enhanced performance, superior quality, and reliability.

The All-in-OneMemory includes a boot NOR Flash, NAND controller, Cache controller, high-speed SRAM, PSRAM, and NAND Flash memory in a Multi Chip Package (MCP).

The embedded NOR Flash offers a fast boot time, and provides many advanced data protection features for secure boot and code protection. The dedicated, performanceoptimized NAND controller provides efficient data integrity, defect management, and wear-leveling by combining a robust hardware Error Correction Code (ECC) and a sophisticated Flash File System (FFS) in the embedded SuperFlash® memory. A built-in cache controller provides both static and dynamic paging modes, with controller-managed, cache-coherence operations.

The SST88VP1107 utilizes the advantages of both NOR and NAND flash memories to attain faster Read, Program, and Erase operations. This unified code and data storage solution allows the host to configure the memory-area and cache sizes for optimum memory utilization.

The All-in-OneMemory is highly configurable. The host device can define a variety of memory configurations using any of the following areas: a direct mapped high-performance 4 Mbit boot NOR memory area, two directly addressable Pseudo-NOR memory areas emulated by RAM and NAND, a directly addressable host RAM memory area, and a performance optimized mass storage area.

Through advanced data protection features, the SST All-in- OneMemory provides robust embedded security. The boot NOR area comes pre-programmed with a 128 Word unique security ID. For greater system security, program the additional 128 Word ID which creates a unique 256 Word security ID. In addition, the boot NOR area offers added security through 32 KWord hardware bottom bootblock protection, two 32 KWord One Time Programmable (OTP) secure areas, volatile block protection, non-volatile block protection, and 64 bit password protection.

The SST88VP1107 offers a built-in Flash File System (FFS) that makes the NAND flash memory management transparent to the host system. This eliminates the need for FFS software on the host, and reduces software development effort and time. The FFS also provides efficient defect management and effective wear-leveling algorithms to ensure even use of NAND flash media, which extend the longevity of the storage device.

The hardware Error Correction Code (ECC) module ensures superior data integrity and reliability by using an advanced ECC algorithm to correct random bit errors for both SLC and MLC NAND flash.

The built-in cache in the High-speed PNOR and PNOR areas improves reliability of these areas. Having a cache in front of the NAND flash helps to reduce the read disturb errors by minimizing repeated direct read access of a page to the NAND flash. The built-in cache also helps to extend the endurance of the storage device by minimizing direct write access to the NAND flash.

The SST88VP1107 is offered in both commercial and wireless temperature ranges in an 80-Ball LBGA package. See Figure 2-1 for pin assignments and Table 2-1 for pin descriptions.
