Shasta+ (IG5216) is a PCIe Gen3 x4, NVMe 1.4 SSD Controller with capacity up to 2TB. Featuring an enhanced DRAM-less architecture with HMB, Shasta+ breaks the existing boundaries to get optimized performance and lower latency, and thus delivers industry-leading performance at low cost.

Shasta+ is designed to speed up SSD sequential transfer, and its advanced Intelligent Power Management Unit enables ultra-low power consumption in active and idle modes. Shasta+ has four NAND channels, supporting SLC, MLC, TLC and QLC with ONFI 4.1 and Toggle 4.0.

Additionally, Shasta+ supports advanced features including multiple data encryption and protection schemes, Smart Cache, integrated Power-On Reset (POR), multi-level power management, NAND boot partition, enhanced QLC performance, simplified PCB design, etc.

Shasta+ has flexible packaging support for BGA and M.2 SSD form factors. It targets a wide range of applications that require ultra-thin and ultra-light weight, ultra-long battery lifespan, and enhanced performance, such as client computing, industrial control, IoT, server boot drives, external storage, embedded systems, etc.

Rainier family includes two members targeting different applications:The IG5236 targets , and IG5636 for data centers and enterprise applications.

Rainier IG5236 , implemented in 12nm FinFET CMOS process, is an industry-leading PCIe Gen4 x4, NVMe 1.4 SSD controller with capacity size up to 8TB.

The IG5236 supports DDR SDRAM with (32+8)-bit or 32-bit wide data bus. Rainier has eight NAND channels, supporting MLC, TLC and QLC with either ONFI 4.1 or Toggle 2.0/3.0/4.0.

The IG5236 is built with the highest-level security with multiple data encryption and protection schemes including AES, SM2/3/4 (China state key), SHA, RSA, ECC, CRC, and end-to-end data protection.

Leveraging InnoGrit’s proprietary ECC technology, data endurance and retention are largely enhanced to deliver better reliability and ultra-high performance for SSD solutions.

Tacoma (IG5668) is a PCIe Gen4 x4, NVMe 1.4 SSD controller with up to 32TB capacity, which adopts 12nm FinFET CMOS process and targets high-end data center, AI and enterprise applications.

Tacoma has 16 NAND channels, supporting MLC, TLC, QLC and XL NAND with ONFI 4.0 and Toggle 3.0. Tacoma supports DDR SDRAM, and it features atomic write and in-storage computation with a deep learning accelerator for optimized system performance.

With optimization for low-latency Storage Class Memory and support of low-latency NAND, Tacoma can reach less than 10us latency for I/O intensive applications to achieve significantly lower cost.

Supporting both conventional SSD mode and Open Channel SSD mode, Tacoma enables customers to deploy and customize their own optimized application solutions. Tacoma adopts multiple encryption and protection schemes, such as InnoGrit’s proprietary ECC technology, to ensure data integrity and enhance data reliability throughout the SSD lifespan. Tacoma has 17mm x 17mm FCBGA package, which can accommodate M.2, U.2, and EDSFF form factors for applications such as high-end data centers, artificial intelligence, enterprise applications, etc.
