A compact System on Chip designed for embedded control, sensing and data logging. It combines a QingKe 32-bit RISC-V V2A core with a broad peripheral set for real-time performance and flexible I/O. Key features and benefits - Core and memory: up to 48 MHz main frequency, 2 KB SRAM, 16 KB flash, and 3.3/5 V supply for easy system integration. - Rich peripherals: general purpose DMA controllers, 10-bit ADC, two 16-bit timers (one for extended control and one all-purpose), two watchdog timers, and a 32-bit SysTick timer for precise timing and reliability. - Robust I/O and interfaces: 1 RT interface, 1 IC interface group, 1 SPI group, 188 I/O ports with external interrupts, and 1-wire serial debug (SDI) interface. - Identification and debugging: unique 64-bit chip ID and SDI debug interface for traceability and diagnostics. - Power and safety: multiple power saving modes (sleep, standby); Power Up/Down Reset and Programmable Voltage Detector for reliable operation during power changes. What it means for you - Flexible system integration with abundant I/O and multiple interfaces on a single chip. - Real-time responsiveness with low interrupt latency and nested interrupt support. - Low-risk design with built-in power management, reset and voltage monitoring. Use scenarios - Industrial sensing node requiring analog measurements, precise timing, and watchdog protection. - Small motor control or robotics controller needing multiple timers and SPI/I/O interfaces. - IoT edge device or data logger needing robust interrupt handling, a compact footprint, and on-chip memory.
