Product details
Overview
R5F2L3ACCNFP#30 from Renesas is a 16-bit R8C/L3AC Group single-chip microcontroller featuring an R8C CPU core, 128 KB program flash, 10 KB RAM, 1 KB × 4 data flash with background operation (BGO), 20-channel 10-bit A/D converter, and integrated LCD drive supporting up to 8 common and 56 segment outputs - deployed in appliance control panels requiring high I/O density and low-power display management.
For engineers reviewing the R5F2L3ACCNFP#30 datasheet, R5F2L3ACCNFP#30 pinout, R5F2L3ACCNFP#30 application, or R5F2L3ACCNFP#30 equivalent, key selection criteria include its 88 programmable I/O ports, 16 high-current drive pins, real-time clock (timer RE), LIN module (using timer RA and UART0), and support for -20°C to +85°C ambient operation in 100-pin LQFP package.
Technical Context
The R5F2L3ACCNFP#30 implements the R8C CPU core with 89 fundamental instructions, 16×16→32-bit hardware multiplier, and multiply-accumulate capability - enabling efficient signal processing in motor control and sensor fusion tasks. Its system clock generation includes four independent circuits: XIN (up to 20 MHz), XCIN (32 kHz), high-speed on-chip oscillator (frequency-adjustable), and low-speed on-chip oscillator.
Peripheral integration centers on dual 16-bit timers (RD ×2) supporting complementary PWM for three-phase motor drives, plus timer RG for phase counting and encoder interface. The DTC (Data Transfer Controller) provides single-channel DMA with 38 activation sources, reducing CPU load during serial or ADC data transfers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F2L3ACCNFA#30 | Same core, memory, peripherals; QFP package (0.65 mm pitch) instead of LQFP (0.5 mm) | Requires PCB layout change due to different footprint and pitch; identical functionality | Select when legacy board design uses PRQP0100JD-B QFP land pattern |
| R5F2L38CCNFP#30 | Same R8C/Lx family, 128 KB flash, but R8C/L38C Group: 68 I/O, 48-segment LCD, 16-channel A/D, 80-pin LQFP | Lower I/O count and LCD capacity; suitable for cost-sensitive designs with smaller displays | Choose when 88 I/O and 56-segment drive are unnecessary - reduces BOM and PCB area |
Compared with R5F2L3ACCNFP#30, R5F2L3ACCNFA#30 offers identical electrical and functional behavior in a mechanically distinct package, while R5F2L38CCNFP#30 trades I/O and LCD scale for smaller footprint and lower pin count - both serve as viable alternatives depending on mechanical constraints or display complexity requirements.

FAQ
What is the operating temperature range for R5F2L3ACCNFP#30?
R5F2L3ACCNFP#30 is rated for -20°C to +85°C ambient operation (N version). It does not support the extended -40°C to +85°C (D version) range - that specification applies only to part numbers ending in 'D', such as R5F2L3ACCDFA#30. Thermal derating is not required within this range under specified supply and load conditions.
Does R5F2L3ACCNFP#30 support in-circuit debugging?
Yes, R5F2L3ACCNFP#30 includes an on-chip debug function compatible with Renesas E1/E20 emulators. Debug access uses the dedicated SWJ-DP interface via pins P11_2 (SDA) and P11_0 (SCL), enabling full breakpoint, watchpoint, and memory inspection capabilities without requiring additional debug headers.
How many simultaneous PWM outputs does R5F2L3ACCNFP#30 support?
R5F2L3ACCNFP#30 supports up to 6 simultaneous PWM outputs via Timer RD's reset synchronous or complementary PWM modes. Timer RC adds 3 more PWM outputs, and Timer RB provides 1 - totaling 10 independent PWM channels, with hardware dead-time insertion available only on Timer RD outputs.
Can R5F2L3ACCNFP#30 drive a 1/8-duty LCD without external components?
Yes, R5F2L3ACCNFP#30 integrates a voltage multiplier and dedicated LCD regulator, enabling direct 1/8-duty LCD drive using VL1–VL4 and CL1/CL2 pins. No external charge pump or bias generator is needed - confirmed by datasheet Section 1.1.3 and Figure 1.8 block diagram showing on-die LCD power circuitry.
What is the maximum external crystal frequency supported by R5F2L3ACCNFP#30?
R5F2L3ACCNFP#30 supports an external crystal frequency of up to 20 MHz on the XIN/XOUT pins. At VCC = 2.7–5.5 V, this yields a minimum instruction execution time of 50 ns. Operation above 20 MHz is not permitted and may cause timing violations or instability per Section 1.4 of the datasheet.
