For engineers reviewing the R5F51115ADFL#30 datasheet, R5F51115ADFL#30 pinout, R5F51115ADFL#30 application, or R5F51115ADFL#30 equivalent, this page delivers verified specifications, package mapping to PLQP0048KB-A (48-pin LFQFP, 7×7 mm, 0.5 mm pitch), functional pin roles, real-world use cases, and two validated alternative parts with technical and application-level distinctions.
Technical Context
The R5F51115ADFL#30 implements the RXv1 core with Harvard architecture, five-stage pipeline, and variable-length instructions-enabling 1-cycle instruction execution and ultra-compact code density. Its clock system integrates high-speed (32 MHz ±1%) and sub-clock (32.768 kHz) oscillators, PLL, and CAC for IEC 60730 compliance.
Peripheral integration includes DTC for interrupt-driven transfers, ELC for direct module linking without CPU wake-up, MTU2 (6-channel 16-bit timer) with complementary PWM and phase counting, and USBc supporting OTG, BC, and isochronous transfer-all operating within a 1.8–3.6 V supply range and −40°C to +85°C temperature grade.
