R7F103GFJ3ZFP#HA0

R7F103GFJ3ZFP#HA0 is a Renesas Electronics RL78/G21 16-bit microcontroller in a 44-pin LQFP package (10 x 10 mm, 0.80 mm pitch) — the embossed-tape packing of the largest-memory 44-pin product in the generation Renesas launched on October 28, 2026. The GFJ 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. A 1.6 V to 5.5 V supply serves legacy 5 V and modern 3.3 V designs, and the -40 °C to +105 °C grade (3Z) covers industrial and consumer enclosures. Selection advice: #HA0 embossed tape feeds pick-and-place lines for volume runs; the same product ships in trays as #BA0 and as the in-catalog #UA0 code, and GFG codes halve the flash to 128 KB in this package where firmware allows. Parameters verified against Renesas Electronics documentation.
