Overview
R5F2L36AANFP#V2 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. It integrates an 8-bit timer RA, 8-bit timer RB, 16-bit timer RC, dual 16-bit timer RD, real-time clock timer RE, 10-bit ADC (10 channels), dual 8-bit DACs, two UARTs, I²C, LIN, and LCD controller supporting up to 8 common and 32 segment outputs - deployed in appliance control panels requiring integrated display drive and low-power operation.
For engineers reviewing the R5F2L36AANFP#V2 datasheet, R5F2L36AANFP#V2 pinout, R5F2L36AANFP#V2 application, or R5F2L36AANFP#V2 equivalent, key selection criteria include its 64-pin LQFP package, -40°C to +85°C industrial temperature grade (D version), BGO-enabled data flash for firmware updates during runtime, and hardware LIN support using timer RA and UART0 - critical for cost-sensitive, display-integrated embedded systems.
Technical Context
The R5F2L36AANFP#V2 implements the R8C CPU core with 89 fundamental instructions, 16×16→32-bit multiplier, and multiply-accumulate capability. Its memory subsystem includes 96 KB on-chip flash (1,000 write/erase cycles) and 1 KB × 4 data flash with BGO, enabling concurrent code execution and data update.
Peripherals are tightly coupled to the CPU via the Data Transfer Controller (DTC), supporting 38 activation sources and two transfer modes. Clock generation includes four independent circuits: 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.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F2L368ADFA | 64 KB program flash (vs. 96 KB), same 64-pin LQFP package, identical D-grade temp range and peripherals | Suitable where firmware size < 64 KB and GA-package variant preferred for alternate PCB layout | Select when lower memory footprint and availability of PLQP0064GA-A package are prioritized over code scalability |
| R5F2L38AANFP | R8C/L38A Group: 68 I/O pins, 16-channel ADC, 80-pin LQFP package - no pin compatibility | Required for designs needing higher I/O count or additional analog inputs beyond 10 channels | Choose only if expanding I/O or ADC channel count justifies PCB redesign and increased package footprint |
Compared with R5F2L368ADFA, R5F2L36AANFP#V2 offers 32 KB more program flash for complex UI logic or future feature expansion; compared with R5F2L38AANFP, it retains the 64-pin footprint and lower system cost but trades off I/O and ADC scalability.

FAQ
What is the operating temperature range for R5F2L36AANFP#V2?
R5F2L36AANFP#V2 is a D-version device rated for -40°C to +85°C ambient operation, validated per Renesas' industrial quality grade specifications. This range supports deployment in non-climate-controlled industrial enclosures and automotive cabin zones. The part number suffix "D" explicitly denotes this extended temperature qualification, distinct from the N-version (-20°C to +85°C).
Does R5F2L36AANFP#V2 support in-system programming via standard interfaces?
Yes, R5F2L36AANFP#V2 supports on-chip debug and in-system flash programming using the single-wire debug interface (SWD) compatible with Renesas E1/E20 emulators. The device includes ROM code protection and ID code check features to secure firmware during field updates, and the background operation (BGO) function allows data flash writes without halting CPU execution.
How many LCD segment and common outputs does R5F2L36AANFP#V2 provide?
R5F2L36AANFP#V2 provides up to 32 segment outputs and 8 common outputs via its integrated LCD controller. This capability is confirmed in Table 1.4 and Section 1.1.2 of the preliminary specification (REJ03B0243-0030), and applies specifically to the R8C/L36A Group - matching the "A" suffix in the part number. Bias options include 1/2, 1/3, and 1/4; duty cycle supports static, 1/2, 1/3, 1/4, and 1/8.
Is R5F2L36AANFP#V2 pin-compatible with other R8C/L36x devices?
R5F2L36AANFP#V2 shares the same 64-pin LQFP (PLQP0064KB-A) package and pin assignment with all R8C/L36A Group variants, including R5F2L367ANFP, R5F2L368ANFP, and R5F2L36CANFP. Pin compatibility is maintained across memory variants and temperature grades (N/D) within the L36A Group, as defined in Figure 1.3 and Table 1.10 of the specification document.
What clock sources are available on R5F2L36AANFP#V2 for real-time clock functionality?
R5F2L36AANFP#V2 uses timer RE in real-time clock mode, driven exclusively by the 32.768 kHz sub-clock (XCIN/XCOU). This low-frequency crystal input is independent of the main XIN oscillator and remains active in wait, stop, and power-off modes - enabling calendar timekeeping with typical current consumption of 1 µA in power-off mode when timer RE is enabled.
