Overview
R5F2L3AACNFP#30 from Renesas is an 88-pin LQFP MCU in the R8C/L3AC Group, featuring the R8C CPU core, 96 KB flash, 10 KB RAM, 20-channel 10-bit ADC, and integrated LCD driver supporting up to 8 common and 56 segment outputs - deployed in appliance control panels requiring real-time sensor processing and segmented display driving.
For engineers reviewing the R5F2L3AACNFP#30 datasheet, R5F2L3AACNFP#30 pinout, R5F2L3AACNFP#30 application, or R5F2L3AACNFP#30 equivalent, this page delivers verified specifications, package mapping, functional alternatives, and design-critical timing/peripheral details directly applicable to household appliance HMI and motor-control subsystems.
Technical Context
The R5F2L3AACNFP#30 implements the R8C CPU core with 89 fundamental instructions and a 16×16→32-bit hardware multiplier, enabling efficient real-time computation for embedded control loops. Its system clock supports four independent sources: XIN (up to 20 MHz), XCIN (32 kHz), high-speed on-chip oscillator (frequency-adjustable), and low-speed on-chip oscillator - with selectable division ratios (1/2/4/8/16) and oscillation stop detection.
Peripheral integration includes Timer RD (16-bit ×2, supporting 6-pin complementary PWM for three-phase motor drive), LIN module (hardware protocol using Timer RA and UART0), DTC (1-channel data transfer controller with 38 activation sources), and background operation (BGO) for concurrent data flash programming during code execution.
