RL78/G23 16-bit MCU with 192 KB Flash — what the 1.6 V floor buys you
The Renesas R7F100GLH2DFB#BA0 is a 16-bit RL78/G23 microcontroller running at 32 MHz with 192 KB of Flash program memory in a 64-pin LQFP. The supply range goes down to 1.6 V.
Industrial temperature grade and peripheral set
Serial connectivity covers CSI, I2C, LINbus, SPI, and UART/USART, so it can bridge to a CAN transceiver, a display driver, or a radio module through the same set of pins.
The product status is listed as Active, meaning Renesas continues to manufacture and support this MCU for new designs. For a production BOM that needs a 16-bit MCU with 192 KB Flash and 54 I/O in a 64-LQFP, this is a straightforward line-item commitment without obsolescence risk.
Package and footprint — 64-LQFP
Housed in a 64-pin LQFP (low-profile quad flat pack), the part is a surface-mount device intended for reflow soldering. The 0.5 mm pitch and exposed pad (if present on this variant) need the usual via-stitch thermal relief under the package for continuous operation near the 85°C ceiling.
