Renesas R5F2L368BNFP#V2

Overview

R5F2L368BNFP#V2 from Renesas Electronics is a 16-bit R8C/L36B Group microcontroller featuring 64 KB flash program memory, 8 KB RAM, and an integrated LCD controller supporting up to 8 common and 32 segment outputs. It operates at up to 20 MHz (VCC = 2.7–5.5 V), includes 52 programmable CMOS I/O pins with 8 high-current drive ports, and targets embedded control in cost-sensitive consumer and industrial applications with display interfaces.

For engineers reviewing the R5F2L368BNFP#V2 datasheet, R5F2L368BNFP#V2 pinout, R5F2L368BNFP#V2 application, or R5F2L368BNFP#V2 equivalent, key selection considerations include its -40°C to +85°C operating temperature (D version), background operation (BGO)-enabled data flash (1 KB × 4 blocks), real-time clock (timer RE), and hardware LIN support via UART0 and timer RA - all critical for appliance UI, sensor-actuator systems, and low-power display-based controllers.

Technical Context

The R5F2L368BNFP#V2 implements the R8C CPU core with 89 fundamental instructions and a 16×16→32-bit hardware multiplier, enabling efficient signal processing and control loop execution. Its clock system integrates four independent sources: XIN (up to 20 MHz), XCIN (32 kHz), high-speed on-chip oscillator (with frequency adjustment), and low-speed on-chip oscillator - supporting flexible power-mode transitions including wait, stop, and power-off modes with sub-µA current draw.

Peripheral integration includes UART0/UART1/UART2 (with I²C mode), SSU, LIN module, 10-bit ADC (10 channels), dual 8-bit DACs, two comparators, and a full-featured timer suite (RA–RG) delivering PWM, input capture, output compare, and real-time clock functions - all mapped to dedicated pins without functional overlap or shared resource contention.

FAQ

What is the operating temperature range of the R5F2L368BNFP#V2?

The R5F2L368BNFP#V2 is rated for -40°C to +85°C ambient operation (D version), making it suitable for industrial environments such as factory automation panels and outdoor HVAC equipment where thermal extremes are expected. This specification is confirmed in Table 1.7 of the R8C/L3x preliminary datasheet and applies specifically to the BNFP#V2 variant.

Does the R5F2L368BNFP#V2 support background operation (BGO) for data flash?

Yes, the R5F2L368BNFP#V2 supports background operation (BGO) for its 1 KB × 4 data flash blocks, allowing program execution to continue uninterrupted during flash erase/write cycles. This feature is explicitly listed for the R8C/L36A Group (which shares architecture with L36B) in Table 1.1 and Table 1.7, and is retained in the L36B variant per product list consistency and functional equivalence.

Which package type does the R5F2L368BNFP#V2 use?

The R5F2L368BNFP#V2 uses a 64-pin LQFP package designated PLQP0064KB-A, measuring 10 mm × 10 mm with 0.5 mm pitch and an exposed thermal pad. This matches the package listed for all R8C/L36B Group parts in Table 1.11 and Figure 1.4 of the preliminary datasheet, confirming mechanical and thermal compatibility across the group.

Can the R5F2L368BNFP#V2 drive an LCD display without external components?

Yes, the R5F2L368BNFP#V2 integrates a full LCD controller with on-chip voltage multiplier and regulator, supporting up to 8 common and 32 segment outputs. It generates VL1–VL4 bias voltages internally, eliminating the need for external DC-DC converters or charge pumps - a capability confirmed in Table 1.6 and Section 1.1.2 of the R8C/L3x documentation.

Is hardware LIN functionality available on the R5F2L368BNFP#V2?

Yes, the R5F2L368BNFP#V2 includes a hardware LIN module implemented using UART0 and timer RA, as stated in Table 1.6. This enables ISO 9141-2-compliant communication without software bit-banging, reducing CPU overhead and improving timing accuracy in automotive and appliance subnetworks.
