R7F103GLJ3ZFA#BA0

R7F103GLJ3ZFA#BA0 is a Renesas Electronics RL78/G21 16-bit microcontroller in a 64-pin LQFP package (12 x 12 mm, 0.65 mm pitch) — the largest pin count and memory in the family generation Renesas launched on October 28, 2026. The GLJ 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 — the widest I/O reach in the family. 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: this #BA0 code is tray-packed; it is also listed as #UA0 (tray) and #HA0 (tape), GLG codes halve the flash to 128 KB here, and the 64-pin LFQFP (FB) codes shrink the body to 10 x 10 mm at 0.50 mm pitch — not interchangeable with this footprint. Parameters verified against Renesas Electronics documentation.
