R7F103GLJ3ZFA#UA0

R7F103GLJ3ZFA#UA0 is a Renesas Electronics RL78/G21 16-bit microcontroller in a 64-pin LQFP package (12 x 12 mm, 0.65 mm pitch, Renesas code PLQP0064JB-A), supplied in trays under the #UA0 packing code. It pairs the largest pin count in the family with the largest memory option: 256 KB code flash, 8 KB SRAM and 4 KB data flash around the 32 MHz RL78-S3 core, on a 1.6 V to 5.5 V supply with a -40 °C to +105 °C grade. Sixty-four pins give the broadest GPIO and peripheral headroom in the RL78/G21 line, while the coarse 0.65 mm pitch keeps soldering and inspection forgiving on cost-led boards. Selection advice: the same product is also listed as #BA0 (tray) and #HA0 (embossed tape); the 64-pin LFQFP codes (ZFB) shrink the body to 10 x 10 mm at 0.50 mm pitch and are not footprint-compatible, and GLG codes halve code flash to 128 KB in this same package, so Parameters verified against Renesas Electronics documentation.
