Arasan Announces NAND Flash Controller PHY and I/O Pad IP compliant to ONFI 4.1 Specifications

Arasan Chip Systems a leading provider of semiconductor IP expands its storage IP Portfolio with ONFI 4.1 PHY and I/O PAD IP seamlessly integrated with its NAND Flash Controller IP.

Aug 15, 2018, San Jose, CA: Arasan today announced the immediate availability of its NAND Flash Controller PHY and I/O Pad IP for 12nm SoC designs compliant to the latest ONFI 4.1 Specifications. The PHY IP is also backward compatible with ONFI 4.0 and 3.2 specifications. In addition to Arasan’s NAND Flash IP Controller, the ONFI NAND PHY and I/O Pad IP can also be easily integrated with customers proprietary NAND Flash Controllers through a standard DDR DFE Interface.

Our NAND Flash PHY IP supports 1.2v and 1.8v out of the box. 2.5v and 3.3v are optionally supported on customer request.

The ACS ONFI 4.1 PHY IP consists of two major sections DFE and an AFE. The ACS ONFI 4.1 PHY IP DFE Contains:

The ACS ONFI 4.0 PHY AFE contains:

The ONFI 4.1 Specification extends NV-DDR3 I/O speeds to 1066 MT/s and 1200MT/s. For better signaling performance, ONFI 4.1 adds Duty Cycle Correction (DCC), Read and Write Training for speeds greater than 800MT/s, support for lower pin cap devices with 37.5 Ohms default output resistance, and devices which require data burst exit and restart for long data input and output pauses. For lower power, 2.5V Vcc support is added. ONFI 4.1 also includes errata to the ONFI 4.0 specification.


The ONFI 4.1 NAND Flash PHY and I/O PAD IP are available immediately for 12nm, 16nm and 28nm SoC Designs.
