⚡ Lumissil IS31CS9202/IS32CS9202 Cortex-M0+ MCUs

Lumissil Microsystems introduces the IS31CS9202 and IS32CS9202, 50 MHz Cortex-M0+ microcontrollers designed for industrial, consumer, and automotive applications. These chips integrate a serial video bus, a LumiBus LED controller, and a capacitive touch-key controller to support complex interface requirements.

Both variants feature 16KB RAM with ECC, split into 8KB for data and 8KB for DMA memory, alongside 256KB flash storage. The memory architecture includes four 1KB Information Blocks with ECC and supports data flash emulation with endurance cycles varying by temperature. Connectivity options include a CAN FD controller, SPI master/slave, I2C master/slave, and two enhanced UART interfaces.

The microcontrollers also incorporate a quadrature encoder, a 14-bit sigma-delta ADC, a 12-bit SAR ADC, and an 8-bit DAC. Up to 42 GPIO pins are available for general-purpose use. The primary distinction lies in the IS32CS9202, which targets automotive environments with a wider operating temperature range of -40°C to 125°C. This variant also carries AEC-Q100 and ASIL-B qualifications, whereas the IS31CS9202 serves general industrial and consumer needs.
