Touch and display driver SoC supports ISO 26262
The ISO 26262-ready touch and display integration (TDDI) SoC, the ILI6600A by Ili Technology (Ilitek), combines the Andes N25F-SE ISO 26262-certified V5 RISC-V CPU core, and the IAR certified Embedded Workbench toolchain for RISC-V. The ILI6600A is an integrated amorphous / LTPS / oxide TFT LCD driver with an in-cell touch controller.
Andes and IAR provide ISO 26262-certified design methodology to shorten the rigorous certification process.
The LCD driver in the ILI6600A supports up to three chips cascading and provides up to 16.7M colours. For the display, there is the impressive image enhancement (IIE) function. The touch panel controller uses a 32-bit high performance single cycle instruction set MCU. Its built in high speed and high performance hardware-accelerated computing modules provide superior data processing capabilities. Ilitek’s driver technology and algorithms contribute anti-noise and a high signal to noise ratio (SNR).
The ILI6600A adopts the AndesCore N25F-SE, claimed to be the world’s first ISO 26262 full-compliance RISC-V CPU. The Safety Enhancement edition of the N25F RISC-V core is designed for automotive functional safety to prevent systematic and random hardware failures. IAR Embedded Workbench for RISC-V is a certified integrated development environment (IDE) including the powerful IAR C/C++ Compiler and a comprehensive debugger.
The ILI6600A is Ilitek’s first ISO 26262 ASIL B-ready product, providing real time and certified fail detection functions. Its high SNR enables touch panel performance. There are also remote AI tuning tools.
The IL6600A analogue front end can scan up to 960ch touch sensors and supports both of LongV and LongH scan,” explained Luen Wey, CEO of ILI Technology. The SoC also supports virtual touch keys and knob functions. It has passed the automotive ESD, EMI, and EMS tests and will soon be an AEC-Q100 grade 2 qualified product, continued Wey.
The functional safety edition of IAR Embedded Workbench for RISC-V is certified by TÜV SÜD according to 10 different standards, including ISO 26262.
Ilitek is one of Taiwan TOP5 IC design houses and has TDDI market share to make it number two worldwide, said the company. It has services offices in China, Korea, Europe and the USA.
