R7F103GGJ3ZFB#HA0

R7F103GGJ3ZFB#HA0 is a Renesas Electronics RL78/G21 16-bit microcontroller in a 48-pin LFQFP package (7 x 7 mm, 0.50 mm pitch), the embossed-tape packing of the 256 KB product in the generation Renesas launched on October 28, 2026. The GGJ code pairs 256 KB code flash with 4 KB data flash and 8 KB SRAM around the 32 MHz RL78-S3 core and a 10-bit ADC. It adds four I/O pins over the 44-pin codes in a smaller 7 x 7 mm body, at a finer 0.50 mm pitch. 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: #HA0 embossed tape is the volume-production packing for reel-fed lines; the same product ships in trays as #BA0 and #UA0, and GGG#HA0 halves the flash to 128 KB in this package and packing.
