Product details
Overview
R5F2L368CDFP#V2 from Renesas is a 16-bit R8C/L36C Group single-chip microcontroller featuring an R8C CPU core, 64 KB flash program memory, 1 KB × 4 data flash with background operation (BGO), 8 KB RAM, and operation at up to 20 MHz (VCC = 2.7–5.5 V). It integrates 52 programmable CMOS I/O ports (including 8 high-current drive pins), 10-bit × 10-channel A/D converter, dual UARTs, I²C, LIN, and LCD drive support (max 8 COM / 32 SEG) for embedded control in appliance and consumer interfaces.
For engineers reviewing the R5F2L368CDFP#V2 datasheet, R5F2L368CDFP#V2 pinout, R5F2L368CDFP#V2 application, or R5F2L368CDFP#V2 equivalent, key selection criteria include its -40°C to +85°C industrial temperature grade, LQFP-64 (0.50 mm pitch) package, integrated voltage detection and watchdog timer, and real-time clock capability via Timer RE - all critical for reliable UI and sensor subsystems in cost-sensitive, low-power designs.
Technical Context
The R5F2L368CDFP#V2 implements the R8C CPU core with 89 fundamental instructions and hardware multiplier (16×16→32 bits), enabling efficient signal processing and control loop execution. Its system clock generation includes four independent circuits: XIN oscillator (up to 20 MHz), XCIN 32-kHz crystal input, high-speed on-chip oscillator (with frequency adjustment), and low-speed on-chip oscillator - supporting flexible power-mode transitions.
Peripheral integration centers on mixed-signal timing and interface functions: Timer RD provides three-phase PWM with complementary output (6-pin) and reset-synchronous modulation; UART2 supports I²C-bus mode and multiprocessor communication; and the LCD controller delivers static/1/2/1/3/1/4/1/8 duty bias with integrated voltage multiplier - all mapped across dedicated I/O ports without resource contention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F2L368CNFP | Same core, memory, and peripherals but rated for -20°C to +85°C (N version) instead of -40°C to +85°C (D version); identical LQFP-64 package. | Suitable for commercial indoor environments only; not qualified for industrial or automotive under-hood use cases requiring extended temperature range. | Select R5F2L368CNFP only when ambient operating temperature remains above -20°C and cost sensitivity outweighs environmental robustness requirements. |
| R5F2L388CDFP | Higher-tier R8C/L38C Group part: adds 6 extra A/D channels (16 total), 12 additional I/O pins (68 total), and 8-segment LCD expansion (48 SEG); same D-grade temp range and LQFP-80 package. | Required when design scales to multi-sensor monitoring or larger segmented displays beyond 32 segments - e.g., advanced kitchen range control panels. | Choose R5F2L388CDFP if future-proofing for higher analog channel count or expanded UI is needed; note PCB layout change required due to 80-pin vs. 64-pin footprint. |
Compared with R5F2L368CNFP, the R5F2L368CDFP#V2 offers guaranteed operation down to -40°C - critical for outdoor or unheated industrial enclosures - while matching all electrical and functional specs. Against R5F2L388CDFP, it trades 6 A/D channels and 16 I/O pins for lower cost and smaller 64-pin footprint, making it optimal for fixed-feature, volume-sensitive appliance UIs.

FAQ
What is the operating temperature range of the R5F2L368CDFP#V2?
The R5F2L368CDFP#V2 is rated for industrial operation from -40°C to +85°C (D version), validated per Renesas specification R01DS0095EJ0101. This extended range ensures reliable startup and sustained functionality in uncontrolled environments such as garage-mounted HVAC systems or factory-floor HMIs where ambient temperatures may dip below freezing or exceed 70°C during peak operation.
Does the R5F2L368CDFP#V2 support in-circuit debugging?
Yes, the R5F2L368CDFP#V2 includes a fully integrated on-chip debug interface compliant with Renesas E1/E20 emulators. It supports real-time breakpoints, memory/register inspection, and flash programming via a single-wire SWD-like interface - eliminating need for external JTAG adapters and enabling rapid firmware iteration directly on target hardware.
How many LCD segment and common lines does the R5F2L368CDFP#V2 drive?
The R5F2L368CDFP#V2 supports up to 32 segment output pins and 8 common output pins, as confirmed in Table 1.3 and Figure 1.10 of the R01DS0095EJ0101 datasheet. This configuration enables driving alphanumeric LCDs up to 8-digit × 7-segment + decimal points or custom 2-line character displays without external segment drivers.
Can the R5F2L368CDFP#V2 perform simultaneous A/D conversions on multiple channels?
No - the R5F2L368CDFP#V2 features a single 10-bit successive-approximation A/D converter with 10 input channels. It supports sweep mode to sequentially convert all enabled channels in one trigger event, but does not provide true simultaneous sampling. For multi-channel synchronized acquisition, external sample-and-hold circuitry or a different MCU family would be required.
What package type and pin pitch does the R5F2L368CDFP#V2 use?
The R5F2L368CDFP#V2 uses a 64-pin LQFP package designated PLQP0064KB-A with 0.50 mm pin pitch, as specified in Table 1.8 and Figure 1.10 of the R01DS0095EJ0101 datasheet. This fine-pitch package requires standard SMT reflow profiles and is compatible with automated pick-and-place equipment used in high-volume consumer electronics manufacturing.
