Product details
Overview
R5F2L3A7CNFP#30 from Renesas is an 88-pin LQFP MCU in the R8C/L3AC Group, featuring the R8C CPU core, 48 KB program flash, 1 KB × 4 data flash with background operation (BGO), 6 KB RAM, and integrated LCD drive supporting up to 8 common and 56 segment outputs. It delivers 10-bit A/D conversion across 20 channels, dual 8-bit D/A converters, and hardware LIN interface - optimized for embedded control in appliance front panels with segmented displays.
For engineers reviewing the R5F2L3A7CNFP#30 datasheet, R5F2L3A7CNFP#30 pinout, R5F2L3A7CNFP#30 application, or R5F2L3A7CNFP#30 equivalent, key selection criteria include its 100-pin LQFP package (PLQP0100KB-A), -20°C to +85°C N-version rating, 20-channel ADC, high-current I/O capability (16 pins), and real-time clock (Timer RE) with calendar-mode support.
Technical Context
The R5F2L3A7CNFP#30 implements the R8C 16-bit CPU core with 89 fundamental instructions and a dedicated 16×16→32-bit multiplier for efficient signal processing. Its system clock supports four independent sources: external XIN (up to 20 MHz), 32-kHz XCIN, and two on-chip oscillators (high- and low-speed), with programmable frequency division (1/2/4/8/16) and oscillation stop detection.
Peripheral integration includes Timer RD (16-bit × 2, supporting 6-pin complementary PWM for motor control), Timer RG (16-bit phase-counting mode), UART0/1/2 (with I²C and LIN modes), DTC for autonomous data transfers, and voltage-detection circuitry with power-on reset and selectable detection levels - all designed for robust, low-EMI operation in consumer-grade environments.

FAQ
What is the maximum operating frequency of the R5F2L3A7CNFP#30?
The R5F2L3A7CNFP#30 supports a maximum operating frequency of 20 MHz when powered at 2.7 V to 5.5 V using the external XIN clock source. At lower supply voltages (1.8 V to 5.5 V), it operates up to 5 MHz - enabling flexible power/performance trade-offs in battery-powered designs. The internal high-speed oscillator also provides a programmable clock source without external crystals.
Does the R5F2L3A7CNFP#30 support in-circuit debugging?
Yes, the R5F2L3A7CNFP#30 includes a full on-chip debug function compliant with Renesas E1/E20 emulators. It supports breakpoints, watchpoints, memory inspection, and flash programming via the single-wire debug interface - enabling development without external JTAG adapters and simplifying production programming workflows.
How many analog input channels does the R5F2L3A7CNFP#30 have?
The R5F2L3A7CNFP#30 features 20 analog input channels for its 10-bit A/D converter, as confirmed in Table 1.5 and Figure 1.8 of the R01DS0095EJ0101 datasheet. These channels are distributed across ports P0, P1, P2, P3, and P13, with dedicated AN0–AN19 labeling - supporting simultaneous sampling of multiple sensors in appliance or HVAC applications.
Can the R5F2L3A7CNFP#30 drive a 1/8-duty LCD without external components?
Yes, the R5F2L3A7CNFP#30 supports 1/8-duty LCD operation natively via its 8 common output pins (COM0–COM7). Unlike smaller R8C groups, the L3AC Group's full 8-COM capability - combined with integrated VL1–VL4 bias generation and voltage multiplier - eliminates the need for external LCD bias ICs or charge pumps in standard 1/8-duty configurations.
What is the purpose of the DTC in the R5F2L3A7CNFP#30?
The Data Transfer Controller (DTC) in the R5F2L3A7CNFP#30 autonomously moves data between memory and peripherals - such as ADC results to RAM or UART transmit buffers - without CPU intervention. With 38 activation sources and repeat/normal transfer modes, it significantly reduces ISR overhead during high-throughput operations like burst ADC sampling or serial streaming.
