Product Overview

32-bit RISC-V EC Famiy

The LS101x is is a highly integrated embedded controller (EC) based on the RISC-V core operating at up to 144MHz frequency. It is targeted for a wide range of portable applications that use the eSPI/LPC interface and is designed to best meet the requirements of mobile systems. It supports a full range of Intel (include MTL), AMD, and domestic CPUs. System support functions include: watchdog, PWM, timers, interrupt control, General-Purpose I/O (GPIO) with internal keyboard matrix scanning, PS/2 interface, SMBus interface, UART, ADC/DAC, system control, system health monitoring and analog controls. The LS101x is targeted for a wide range of portable applications.
