It targets embedded control in household appliances and office equipment requiring low-power operation and integrated display driving.

For engineers reviewing the R5F2L367ADFP#U1 datasheet, R5F2L367ADFP#U1 pinout, R5F2L367ADFP#U1 application, or R5F2L367ADFP#U1 equivalent, key selection considerations include its -40°C to +85°C industrial temperature grade (D version), 64-pin LQFP package (PLQP0064KB-A), BGO-enabled data flash for runtime reprogramming, and hardware LIN support using Timer RA and UART0 - critical for appliance motor control and user-interface subsystems.

Technical Context

The R5F2L367ADFP#U1 implements the R8C CPU core with 1 Mbyte address space, 16×16→32-bit multiplier, and multiply-accumulate instruction. 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/performance trade-offs across wait, stop, and power-off modes.

Its peripheral set includes Timer RA (8-bit, pulse output), Timer RB (8-bit, PWM), Timer RC (16-bit, 3-channel PWM), Timer RD (16-bit ×2, 6-channel PWM with complementary/synchronous modes), Timer RE (real-time clock), DTC (1 channel, 38 activation sources), and voltage detection circuitry with selectable reset thresholds - all coordinated under a 7-level priority interrupt system with 69 vectors.

FAQ

What is the operating temperature range of the R5F2L367ADFP#U1?

The R5F2L367ADFP#U1 is the D-version device, rated for an operating ambient temperature range of -40°C to +85°C. This specification is confirmed in Table 1.7 of the R8C/L3x preliminary datasheet (REJ03B0243-0030 Rev.0.30) and applies to all R5F2L36x series parts ending in "DFP". It meets industrial-grade requirements for deployment in kitchen appliances, HVAC controls, and factory-floor equipment where cold-start reliability is essential. The R5F2L367ADFP#U1 does not support extended temperature grades beyond this range.

Does the R5F2L367ADFP#U1 support background operation (BGO) for data flash?

Yes, the R5F2L367ADFP#U1 supports background operation (BGO) for its 1 KB × 4 data flash blocks. As specified in Section 1.1 and Table 1.5 of the R8C/L3x datasheet, BGO allows simultaneous CPU program execution and data flash erase/write operations - critical for in-field calibration updates or logging without system interruption. This feature is exclusive to the "A" subgroups (R8C/L35A, L36A, L38A, L3AA) and is confirmed for R5F2L367ADFP#U1 in Table 1.10's product list and functional description.

What package type and pin count does the R5F2L367ADFP#U1 use?

The R5F2L367ADFP#U1 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 is explicitly listed in Table 1.10 (Product List for R8C/L36A Group) and Figure 1.3 of the datasheet. The "FP" suffix in the part number denotes LQFP packaging, and the R5F2L367ADFP#U1 shares pinout compatibility with other R8C/L36A Group members in the same package variant, including identical I/O mapping and peripheral pin assignments.

Which communication interfaces are integrated into the R5F2L367ADFP#U1?

The R5F2L367ADFP#U1 integrates UART0, UART1, and UART2 (with I²C-bus mode), a synchronous serial unit (SSU) shared with I²C, and a hardware LIN module. UART2's I²C capability and SSU sharing are detailed in Table 1.6; the LIN function uses UART0 and Timer RA per Section 1.1.1. It does not include SPI or CAN controllers. These interfaces enable direct connection to LCD drivers (I²C), motor control ICs (LIN), and legacy peripherals (UART), making the R5F2L367ADFP#U1 suitable for multi-protocol appliance subsystems without external bridge ICs.

How many analog-to-digital converter (ADC) channels does the R5F2L367ADFP#U1 provide?

The R5F2L367ADFP#U1 provides a 10-bit successive approximation register (SAR) ADC with 10 input channels, including sample-and-hold and hardware sweep mode. This is specified in Table 1.6 under "A/D Converter" for the R8C/L36A Group and confirmed in Table 1.10's product listing. The ADC supports differential and single-ended configurations and is mapped to dedicated analog input pins (e.g., AN0–AN9), enabling simultaneous monitoring of multiple sensors such as thermistors, potentiometers, and current shunts in appliance control loops.
