Product details

24 MHz RL78 core with on-chip LCD drive

The R5F10RJ8GFA#10: The 8 KB program flash and 1 KB RAM suit control panels, metering, or battery-operated displays where the code footprint stays tight. 2 KB on-chip EEPROM stores calibration or configuration data without an external serial memory.

52-LQFP with 30 I/O — board-fit facts

Housed in a 52-LQFP (10x10 mm body), surface-mount. 30 general-purpose I/O are available after the LCD segment pins are allocated. Connectivity includes CSI (serial), I²C, LINbus, and UART/USART — enough for sensor buses, local display communication, or LIN node interfaces in automotive-adjacent designs.

ADC and oscillator — no external crystal required

The on-chip A/D converter provides 10 channels at 8- or 10-bit resolution. For a segmented LCD panel with a few pushbuttons and an analog sensor, this MCU covers the entire signal chain without external ADC or clock ICs.

Frequently asked questions

What is the closest functional second-source to R5F10RJ8GFA#10?

The R5F101GGAFB#30 (RL78/G13) is a close peer — same RL78 core, 16-bit, similar peripheral set (CSI, I²C, LINbus, UART/USART, DMA, LVD, POR, PWM, WDT) but runs at 32 MHz and has 34 I/O. However, the R5F101GGAFB#30 lacks the on-chip LCD driver and operates only to 85°C. For a drop-in replacement without rewiring, the R5F10RJ8GFA#10 is the LCD-equipped variant in the RL78/L12 series — confirm your LCD segment count and temperature requirement before swapping.
