Nuvoton Releases 4th Generation of "Gerda (TM)," Automotive HMI Display IC Series, in 3 Variants
KYOTO, Japan, June 6, 2025 /PRNewswire/ -- Nuvoton Technology Corporation Japan (NTCJ) will start the mass production of its 4th-generation automotive HMI (Human-Machine Interface) display IC series, Gerda (TM), available in three variants: Gerda-4M, Gerda-4L, and Gerda-4C. This new lineup features image-processing technology, security, and display safety functions to support the higher level of safety requirement and more comfortable driving experiences. The Gerda (TM) IC contributes to the development of next-generation HMI systems by enabling high-performance, cost-effective solutions across a wide range of applications. Image: 1. Superior image-processing engine for improving visibility and comfort of HMI equipment For Electronic Mirrors Gerda-4M solves the issues that conventional e-mirrors have, such as glare caused by strong lights and reduced visibility due to loss of detail in high-contrast lighting scenarios, especially at night, by using a "local contrast function" that locally adjusts the screen contrast based on the luminance distribution of each area. In addition, low-latency processing of less than one frame enables real-time display improvements. Figure1: For AR-HUDs AR-HUD displays must align precisely with windshield curvature and driver's line of sight. The image-warping engine in Gerda (TM) enables free image deformation with low latency of less than one frame, allowing it to fit the windshield. It also supports "dual projection," which projects images both near and far focus with a single chip. Figure2: For Cluster Meters With a 2.5D graphics engine (GFX), Gerda (TM) enables user interface (UI) design that simulates 3D effects using 2D elements. This improves depth perception and readability, contributing to more accurate and timely decision-making by the driver. Additionally, in combination with an image compression engine, it supports high-resolution output of WXGA@60FPS, providing a modern, high-quality dashboard experience. 2. Generally, high-performance HMI solutions require external memory. NTCJ's Gerda (TM) Gen-4 series is embedded with high speed and large capacity memory which eliminates external memory, helping to reduce the number of components and system costs. In addition, Gerda-4L is equipped with a dedicated image compression engine, achieving real-time processing while using only half the memory -- making it possible to display high-resolution images at WXGA@60FPS only using embedded memory. Figure3: 3. The Gen-4 Gerda (TM) lineup includes display safety functions such as video signal monitoring and alert display monitoring, and contributes to realizing system designs that meet ISO26262 ASIL-B requirements by supporting fail-safe and real-time monitoring. Additionally, the integrated Hardware Security Module (HSM), compliant with EVITA-Full, enables secure OTA software updates and a secure boot which allows only trusted software boots -- protecting against vehicle cybersecurity threats. NTCJ is the first Japanese company which has been certified with the TUV process of ISO/SAE21434 and continues to improve cybersecurity at supply chains and its reliability.

Nuvoton Releases Plan to Launch Mass Production of New Industrial BM-ICs
KYOTO, Japan, Feb. 20, 2025 /PRNewswire/ -- Nuvoton Technology Corporation Japan (NTCJ) has developed new industrial 17-cell BM-ICs "KA49701A" and "KA49702A" for 48V batteries. Mass production will start from April 2025. These products enhance the safety of battery systems and ensure simple safe system construction. Image: 1. The battery monitoring ICs play a role in ensuring the system operates safely during anomalies such as overcharging or over-discharging of the battery. However, if the main circuits performing cell voltage measurements such as the AD converter or multiplexer of the BM-IC fail, it needs to ensure system safety with external protection circuits, but this increases board area and system cost. The major internal circuits of this product are equipped with diagnostic and fail-safe functions. This diagnostic function can detect main circuit failures and control the cut-off switch, achieving both enhanced BMS safety and reduced system cost. Figure (English): Figure (Simplified Chinese): Figure (Traditional Chinese): 2. By reducing noise levels on the 16-bit AD converter and incorporating a digital filter, NTCJ has achieved industry-leading voltage measurement accuracy of +/-2.9mV (*1). By improving voltage measurement accuracy, maximum battery capacity can be used. Furthermore, precise voltage measurement has been achieved over a wide temperature range. It is also suitable for applications requiring high voltage measurement accuracy in cold and hot environments, such as stationary battery systems compliant with the relevant Chinese national standard (*2). (*1) According to a survey by Nuvoton in the industrial BM-IC field as of February 2025.(*2) GB/T34131-2023, within the system +/-5mV @-20C to 65C. 3. By shortening the cell voltage measurement time, which has high power consumption, operating current has been achieved at 260 microampere, less than 1/10th of NTCJ's previous standards. This enables long battery drive times. Also, optimization of the circuit design has reduced shutdown current consumption to 0.1 microampere or less. Using NTCJ's IC, self-discharge can be minimized, preventing deterioration due to over-discharge when LIBs are transported over long distances and stored long-term.
