Product details
Overview
R5F2L368BNFP#U1 from Renesas Electronics is a 16-bit R8C/L36B Group microcontroller featuring the R8C CPU core, 64 KB flash program memory, 8 KB RAM, and operation at up to 20 MHz (VCC = 2.7–5.5 V). It integrates a 10-bit ADC (10 channels), dual 8-bit DACs, LCD controller (up to 8 COM / 32 SEG), UART/I²C/SSU serial interfaces, and multiple timers including PWM-capable Timer RD. It targets embedded control in consumer appliances with integrated display and sensor interfacing.
For engineers reviewing the R5F2L368BNFP#U1 datasheet, R5F2L368BNFP#U1 pinout, R5F2L368BNFP#U1 application, or R5F2L368BNFP#U1 equivalent, key selection criteria include its -40°C to +85°C industrial temperature grade (D version), 64-pin LQFP package (PLQP0064KB-A), background operation (BGO)-enabled data flash absence, and hardware LIN support via UART0 and Timer RA.
Technical Context
The R5F2L368BNFP#U1 implements the R8C CPU core with 89 fundamental instructions, 16×16→32-bit multiplier, and multiply-accumulate capability. It operates in single-chip mode with a 1 Mbyte address space and supports four clock sources: XIN (up to 20 MHz), XCIN (32 kHz), high-speed on-chip oscillator (adjustable), and low-speed on-chip oscillator.
Its peripheral set includes Timer RA (8-bit, pulse output/event counter), Timer RB (8-bit, PWM/one-shot), Timer RC (16-bit, 4 capture/compare), Timer RD (16-bit ×2, 6-pin PWM/reset-synchronous/complementary modes), Timer RE (real-time clock), and DTC (1-channel, 38 activation sources). The device lacks data flash but retains full on-chip debug and flash rewrite functionality.

FAQ
What is the operating temperature range of the R5F2L368BNFP#U1?
The R5F2L368BNFP#U1 is rated for -40°C to +85°C ambient operation (D version), qualifying it for industrial and extended-temperature consumer applications such as kitchen appliances, HVAC controls, and outdoor sensor nodes where thermal stability is critical. This specification is confirmed in Table 1.7 of the R8C/L3x preliminary datasheet.
Does the R5F2L368BNFP#U1 include data flash memory?
No, the R5F2L368BNFP#U1 does not include data flash memory. As a member of the R8C/L36B Group, it omits the 1 KB × 4 data flash with background operation (BGO) found in the A-series variants (e.g., R5F2L368ANFP#U0). Its non-volatile storage consists solely of 64 KB program flash ROM, which supports 1,000 write/erase cycles per Table 1.7.
Which package type is used by the R5F2L368BNFP#U1?
The R5F2L368BNFP#U1 uses a 64-pin LQFP package designated PLQP0064KB-A - a 10 mm × 10 mm body with 0.5 mm lead pitch. This package is explicitly listed in Table 1.11 (R8C/L36B Group Product List) and matches the pin assignment diagrams in Figures 1.4 and 1.14 of the R8C/L3x preliminary specification.
Can the R5F2L368BNFP#U1 drive an LCD display directly?
Yes, the R5F2L368BNFP#U1 integrates a dedicated LCD controller supporting up to 8 common and 32 segment outputs, with selectable bias (1/2, 1/3, 1/4) and duty (static to 1/8). It includes on-chip voltage multiplier and regulator, enabling direct drive of multiplexed LCDs without external bias circuitry - confirmed in Table 1.6 and Section 1.1.2 of the datasheet.
What debug capabilities does the R5F2L368BNFP#U1 support?
The R5F2L368BNFP#U1 supports full on-chip debug (OCD) via a dedicated serial interface, enabling real-time breakpoints, watchpoints, register inspection, and flash programming without external emulators. This capability is documented in Table 1.7 under "Debug functions" and is consistent across all R8C/L3x Group devices, including the L36B variant.
