R7F103GLG3ZFA#UA0

R7F103GLG3ZFA#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 carries 128 KB code flash, 8 KB SRAM and 4 KB data flash around the 32 MHz RL78-S3 core, with a 1.6 V to 5.5 V supply range and a -40 °C to +105 °C grade shared across the family. With the full 64-pin count and the easier 0.65 mm pitch, it fits designs that need many control and communication lines on boards where fine-pitch assembly is unwanted. Selection advice: the datasheet lists this product under three packing codes — #BA0 and #UA0 in trays and #HA0 on embossed tape — so quote the complete code rather than the product name alone. The GLJ codes double code flash to 256 KB in the same package, and the 64-pin LFQFP codes (ZFB) trade the body down to 10 x 10 mm at 0.50 mm pitch on an incompatible footprint.
