Product details
Overview
R5F2L3ACCNFP#V0 from Renesas is a 16-bit R8C/L3AC Group microcontroller featuring an R8C CPU core, 128 KB flash program memory, 10 KB RAM, and integrated LCD drive control 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 multiple timer peripherals including Timer RD (16-bit × 2) for three-phase PWM generation. It targets embedded control in appliance front panels with integrated display and sensor interfacing.
For engineers reviewing the R5F2L3ACCNFP#V0 datasheet, R5F2L3ACCNFP#V0 pinout, R5F2L3ACCNFP#V0 application, or R5F2L3ACCNFP#V0 equivalent, key selection criteria include its 100-pin LQFP package, -20°C to +85°C operating range (N version), background operation (BGO) data flash capability, and hardware LIN support via UART0 and Timer RA.
Technical Context
The R5F2L3ACCNFP#V0 implements the R8C CPU core with 89 fundamental instructions and a 16×16→32-bit hardware multiplier, enabling efficient signal processing and real-time control. Its clock system integrates four independent sources: XIN oscillator (up to 20 MHz), XCIN (32 kHz), high-speed on-chip oscillator (frequency-adjustable), and low-speed on-chip oscillator - all selectable via software-controlled frequency dividers (1/2/4/8/16).
Peripheral integration includes a Data Transfer Controller (DTC) with 38 activation sources and two transfer modes, a watchdog timer with selectable reset start and dedicated low-speed oscillator, and a voltage detection circuit supporting power-on reset and dual-level voltage monitoring. The MCU supports low-power operation down to 0.02 µA in power-off mode at 3.0 V.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F2L38CCNFP | 80-pin LQFP, 128 KB flash, 16-channel A/D, 48-segment LCD drive | Fewer I/O (68 pins) and reduced LCD capacity - suitable for smaller displays or lower sensor count designs | Select when board space or display complexity is constrained but same R8C/Lx software ecosystem is required. |
| R5F2L36CCNFP | 64-pin LQFP, 128 KB flash, 10-channel A/D, 32-segment LCD drive | Lower I/O count (52 pins), no Timer RG or VL3 pin - limits three-phase PWM and LCD bias flexibility | Choose for cost-sensitive, space-constrained applications where full 56-segment LCD and 20-channel A/D are unnecessary. |
Compared with R5F2L3ACCNFP#V0, R5F2L38CCNFP offers reduced pin count and LCD capability but retains identical flash/RAM and core features, while R5F2L36CCNFP further scales down I/O and analog resources - both maintain binary-compatible toolchain and peripheral register mapping within the R8C/Lx family.

FAQ
What is the maximum operating frequency and supply voltage range for the R5F2L3ACCNFP#V0?
The R5F2L3ACCNFP#V0 operates at up to 20 MHz when supplied at 2.7–5.5 V, and supports reduced-frequency operation (5 MHz) down to 1.8 V for ultra-low-power applications. Its voltage detection circuit monitors VDD and triggers reset if supply falls below programmable thresholds, ensuring reliable startup and brown-out recovery.
Does the R5F2L3ACCNFP#V0 support in-system programming and data retention during firmware updates?
Yes, the R5F2L3ACCNFP#V0 supports on-chip debug and background operation (BGO) for data flash. This allows rewriting of its 4 KB data flash (1 KB × 4 blocks) while the main application continues running - essential for updating calibration data or language strings without interrupting system function.
How many analog input channels does the R5F2L3ACCNFP#V0 provide, and what is their resolution?
The R5F2L3ACCNFP#V0 integrates a 10-bit successive-approximation A/D converter with 20 input channels (AN0–AN19), including sample-and-hold and hardware sweep mode. Channels are mapped across P0, P1, P2, P3, and P13 pins, enabling simultaneous multi-sensor acquisition in appliance control applications.
What LCD display configurations are supported by the R5F2L3ACCNFP#V0's built-in controller?
The R5F2L3ACCNFP#V0 supports static, 1/2, 1/3, 1/4, and 1/8 duty LCD drive with up to 8 common (COM0–COM7) and 56 segment (SEG0–SEG55) outputs. Its integrated voltage multiplier and VL1–VL4 pins generate required bias voltages, eliminating external components for most character and segmented displays.
Is the R5F2L3ACCNFP#V0 pin-compatible with other members of the R8C/Lx series?
No, the R5F2L3ACCNFP#V0 uses a 100-pin LQFP package (PLQP0100KB-A), while other R8C/Lx variants use 52-, 64-, or 80-pin packages. Although register-level peripheral compatibility exists within the R8C/Lx family, PCB layout and pin mapping are not interchangeable - migration requires board redesign.
