All-in-One Microcontroller For Contact-Pushed Interfaces

– Commercial –

A flexible RISC-V (lowered instruction set laptop) microcontroller integrates contact management and LED (gentle emitting diode) matrix driving, providing superior options like sound suggestions and environmental resistance, making it ideally suited for automotive and industrial purposes.

The IS31CS9310 mannequin launched by Lumissil Microsystems is tailor-made for industrial purposes, whereas the AEC-Q100 grade-1 certified IS32CS9310 is suited to automotive environments. Each variations function an 8 x 12 LED matrix driver as a key element, integrating eight PMOS (p-channel metallic–oxide–semiconductor) switches and twelve 80mA PWM (pulse-width modulation)-controlled present sinks. This permits for particular person LED brightness changes throughout 4,096 ranges and gives management for your entire matrix throughout 256 ranges. This product primarily targets producers and builders in sectors equivalent to client electronics, automotive, and industrial automation, who search environment friendly, built-in options for interactive shows.

“They function built-in non-volatile reminiscence to retailer LED parameters important for dynamic lighting results equivalent to colour transition, pulsing, fading, and animated patterns,” the corporate acknowledged. To mitigate potential electromagnetic interference (EMI) from high-frequency LED operations, these drivers incorporate unfold spectrum frequency modulation. Moreover, a de-ghosting circuit addresses LED ghosting points, making certain readability in illumination.

The microcontroller additionally features a contact interface able to managing as much as 16 capacitive contact keys in self-capacitance mode or an 8 x 8 matrix in mutual capacitance mode, which permits eight-channel proximity sensing for gesture detection. “These contact key sensors provide water and dirt resistance, making certain dependable operation in environments liable to moisture or splashes,” firm claims.

Sound suggestions is supplied by an built-in melody controller that helps 14-bit frequency management, length, and pause changes. The structure permits for double-buffering, enabling a brand new observe to be performed whereas one other remains to be in progress.

The microcontroller is supplied with 256 KB of flash reminiscence, 16 KB of knowledge RAM, and 16 KB of DMA (Direct reminiscence entry) RAM, powered by a 32 MHz 32-bit RISC-V processor. The processor options configurable pipeline depth and execution varieties, with dynamic voltage and frequency scaling for optimum power effectivity.

Supporting over-the-air updates and that includes a debugging port, the IC is appropriate for a spread of purposes, together with home home equipment, automotive dashboards, and industrial management panels. The working temperature ranges from -40 to +85°C for the IS31 mannequin and -40 to +125°C for the IS32.
