IS31CS9310 RISC-V MCU

Lumissil RISC-V MCUs are designed with a touch sensor and LED matrix driver

Image of Lumissil IS31CS9310 RISC-V MCUThe IS31CS9310 from Lumissil is a 32-bit RISC-V MCU equipped with 256 KB of NVM and features a Gen 3 touch-key controller and 8 x 12 LED matrix driver.

The IS31CS9310 is suited for industrial/consumer command and control applications, including HMI (human-machine interface) control panels, industrial control systems, or any applications requiring user interaction and an LED matrix driver.

Features
  • Up to 16 water- and dust-resistant Gen 3 touch sensors:
    • Supports self-capacitance and mutual-capacitance mode
    • Individual key calibration
    • Touch keys reconfigured as proximity sensors
    • Auto sleep and wake modes
 
  • 32-bit RISC-V with 256 KB e-Flash supports custom GPIO firmware and LED control patterns
  • 8 x 12 LED matrix driver includes anti-ghost circuitry and spread spectrum
  • Fast 400 kHz I2C, SPI, and EUART communications
  • Wide array of analog and digital peripherals includes an ADC/DAC and PWM
Applications
  • HMI control panel:
    • MCU processes touch key commands, drives LED panel, and controls LED backlight through PWM while simultaneously processing other miscellaneous functions
  • White goods:
    • MCU processes touch key commands and drives LED displays while processing programmed commands
 
  • Security and access control:
    • MCU manages security systems, including door access controls and alarm systems
