R7F103GGG3ZFB#UA0

R7F103GGG3ZFB#UA0 is a Renesas Electronics RL78/G21 16-bit microcontroller in a 48-pin LFQFP package (7 x 7 mm, 0.50 mm pitch), the 128 KB tier in the generation Renesas launched on October 28, 2026. The GGG code carries 128 KB code flash — half the GGJ size — with SRAM and data flash unchanged at 8 KB and 4 KB, around the same 32 MHz RL78-S3 core and 10-bit ADC. The 48-pin body keeps the extra GGJ I/O in the same compact 7 x 7 mm footprint. A 1.6 V to 5.5 V supply and the -40 °C to +105 °C grade (3Z) cover legacy and modern rails. Selection advice: this #UA0 code is tray-packed; pick GGG for cost-led 48-pin builds; the same product is listed in trays as #BA0 and on tape as #HA0, and GGJ doubles the flash in the identical package. Parameters verified against Renesas Electronics documentation.
