Overview
The STC89LE51RC is a STC made by STC Micro in a LQFP-44(10x10) package with 44 pins. LQFP-44(10x10) Microcontrollers (MCU/MPU/SOC) ROHS.
PCBKit's library has its KiCad symbol (EasyEDA_Cloud:STC89LE51RC, from EasyEDA) and its footprint (Package_QFP:LQFP-44_10x10mm_P0.8mm, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C8749).
