R7F103GLJ3ZFB#UA0

R7F103GLJ3ZFB#UA0 is a Renesas Electronics RL78/G21 16-bit microcontroller in a 64-pin LFQFP package (10 x 10 mm, 0.50 mm pitch, Renesas code PLQP0064KB-C), supplied in trays under the #UA0 packing code. It carries the largest memory in the compact body: 256 KB code flash, 8 KB SRAM and 4 KB data flash, driven by 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 in a 10 x 10 mm outline suit dense control boards that need the peripheral set of the top package without its area. Selection advice: this product is also listed as #BA0 (tray) and #HA0 (embossed tape), so quote the complete code including the suffix. Where assembly prefers a coarser pitch, the 64-pin LQFP codes (ZFA) hold the same 256 KB in a 12 x 12 mm body on a different footprint; where firmware is compact, the GLG codes in this LFQFP package cut flash to 128 KB. Parameters verified against Renesas Electronics documentation.
