Product details
Overview
R5F2L36AANFP#U1 from Renesas Electronics is a 16-bit R8C/L36A Group microcontroller featuring the R8C CPU core, 96 KB program flash, 1 KB × 4 data flash with background operation (BGO), 10 KB RAM, and 52 programmable CMOS I/O pins in a 64-pin LQFP package. It integrates LCD drive control (up to 8 common/32 segment outputs), 10-bit ADC (10 channels), dual UARTs, I²C, LIN, and multiple timer modules - deployed in appliance control panels requiring integrated display driving and low-power operation.
For engineers reviewing the R5F2L36AANFP#U1 datasheet, R5F2L36AANFP#U1 pinout, R5F2L36AANFP#U1 application, or R5F2L36AANFP#U1 equivalent, key selection criteria include its N-grade temperature range (−20°C to +85°C), on-chip debug support, BGO-enabled firmware updates, and dedicated LCD bias regulator - critical for cost-sensitive consumer HMI designs with segmented displays.
Technical Context
The R5F2L36AANFP#U1 implements the R8C CPU core with 89 fundamental instructions, 16×16→32-bit hardware multiplier, and 1 Mbyte address space. It supports four clock sources: external XIN (up to 20 MHz), 32 kHz XCIN, high-speed on-chip oscillator (adjustable), and low-speed on-chip oscillator - enabling flexible power-mode transitions between active, wait, stop, and power-off modes.
Peripheral integration includes Timer RA/RB (8-bit), Timer RC/RD (16-bit with PWM and three-phase output), real-time clock (Timer RE), DTC for autonomous data transfers, and dual comparators. The LCD controller provides 1/2, 1/3, or 1/4 bias and static/1/2/1/3/1/4/1/8 duty options - all configurable without external components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F2L368ANFP | 64 KB program flash (vs. 96 KB), same 52-pin LQFP, identical peripherals and BGO capability | Suitable where firmware footprint < 64 KB; lower memory density reduces cost but limits future feature expansion | Select when application code size is confirmed ≤ 64 KB and long-term firmware scalability is not required. |
| R5F2L36AANFA | Same 96 KB flash and peripherals, but 64-pin LQFP with different land pattern (PLQP0064GA-A vs. PLQP0064KB-A) | Requires PCB layout revision due to alternate pinout and thermal pad configuration | Choose only if PLQP0064GA-A footprint is already standardized in production; not drop-in compatible with R5F2L36AANFP#U1. |
Compared with R5F2L368ANFP, R5F2L36AANFP#U1 provides 32 KB more program flash for enhanced feature sets and bootloader flexibility; compared with R5F2L36AANFA, it uses the PLQP0064KB-A package - ensuring mechanical and thermal compatibility with existing 64-pin LQFP reflow profiles.
