Product details
Overview
R5F12067GSP#30 from Renesas Electronics is a 20-pin, 4 KB code flash, 1 KB RAM RL78/G15 16-bit microcontroller with industrial-grade temperature range (−40°C to +105°C), high-speed on-chip oscillator (1–16 MHz), 8/10-bit A/D converter (11 channels), and integrated UART, CSI, and I²C interfaces. It targets low-power embedded control in HVAC sensors, motor-driven appliances, and industrial I/O modules.
For engineers reviewing the R5F12067GSP#30 datasheet, R5F12067GSP#30 pinout, R5F12067GSP#30 application, or R5F12067GSP#30 equivalent, key selection criteria include its 20-pin LSSOP package, G-grade thermal rating, 4 KB flash / 1 KB data flash memory split, 11-channel analog input capability, and support for background operation-free data flash writes at VDD = 2.4–5.5 V.
Technical Context
The R5F12067GSP#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and 1 MB address space. It supports dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy at −20°C to +85°C) and 15 kHz low-speed oscillator for watchdog operation.
Its peripheral set includes an 8-channel 16-bit timer array (TAU0), 12-bit interval timer, watchdog timer, two comparators (IVCMP0/IVCMP1), and programmable clock/buzzer output (PCLBUZ0). Serial interfaces comprise one UART channel, two simplified SPI (CSI) channels, two simplified I²C channels, and one full I²C bus interface (IICA0).
