New Chip Packs Cortex-M0+ with Video Bus, Touch Controls, and LED Magic

Lumissil Microsystems has unveiled the IS31CS9202 and IS32CS9202, two new microcontrollers built around a 50 MHz Arm Cortex-M0+ core. These chips are designed as integrated solutions for industrial, consumer, and automotive products, packing 256KB of flash, 16KB of RAM, and a wide array of peripherals including CAN FD, I2C, SPI, and enhanced UART interfaces. The IS32CS9202 variant is specifically hardened for automotive use, with a wider operating temperature range and AEC-Q100/ASIL-B qualifications.

The key differentiators for engineers are the inclusion of a Serial Video Bus (SVB) controller for video data, a dedicated LumiBus LED controller, and a capacitive touch-key controller capable of handling up to 39 keys. This combination of video, lighting, and touch control in a single, power-efficient package (drawing under 100uA/MHz) makes these MCUs particularly suited for creating rich, interactive human-machine interfaces in appliances, automotive dashboards, and industrial panels. This release represents a move towards more specialized, application-focused microcontroller designs that bundle complex interface logic into a single chip.
