Active RL78/G1N — 20 MHz, 8 KB Flash, 16 I/O in 20-TSSOP
The R5F11Y68ASM#50 is an active-production 16-bit microcontroller from the Renesas RL78/G1N series, built around the RL78 core running at 20 MHz. The 20 MHz clock rate sets the throughput ceiling for control loops and serial communication tasks; the 8 KB Flash accommodates firmware for small embedded applications such as sensor nodes, motor control interfaces, or human-machine interface (HMI) panels. The 1 KB RAM provides stack and variable space for interrupt-driven or buffered I/O operations.
Supply range, temperature grade, and on-chip peripherals
On-chip peripherals include a power-on reset (POR) and watchdog timer (WDT) for unattended or safety-critical operation, plus an 8-channel 8/10-bit analog-to-digital converter (ADC) that reads analog sensors without an external converter chip. Serial connectivity is handled by CSI (clocked serial interface) and UART/USART modules, sufficient for communicating with displays, host controllers, or sensor modules.
Compliance and sourcing posture
Rated ROHS3 compliant, the part meets EU and global regulatory requirements without exemption paperwork.
