Product details
Overview
R5F10FLCDNA#U0 from Renesas Electronics is a 16-bit RL78/G1E microcontroller with integrated smart analog functions, featuring 64 KB flash memory, 4 KB RAM, and a 32 MHz max CPU clock. It includes a 12-bit ADC (12-channel), 12-bit DAC (4-channel), programmable gain amplifier (PGA), and hardware multiplier-designed for sensor signal conditioning and closed-loop control in compact industrial and consumer systems.
For engineers reviewing the R5F10FLCDNA#U0 datasheet, R5F10FLCDNA#U0 pinout, R5F10FLCDNA#U0 application, or R5F10FLCDNA#U0 equivalent, key selection criteria include its 64-pin LQFP package, on-chip analog front-end (AFE) with MPXIN/AMP/DAC channels, low-power RL78 core architecture, and support for single-supply operation with internal LDO and bandgap reference.
Technical Context
The R5F10FLCDNA#U0 implements the RL78 CPU core with 16-bit CISC architecture, supporting 1.6–5.5 V operation and sub-μA standby current via deep software stop mode. Its analog subsystem integrates a 12-bit SAR ADC with selectable sample-and-hold and programmable conversion timing, plus four independent 12-bit DACs with configurable output buffers and slew-rate control.
Digital peripherals include 16-bit timer arrays (TAA/TAB), UART/SIM (with LIN support), I²C-compatible interface, and 16-bit PWM with dead-time insertion. The device uses Renesas' SuperFlash® technology for 100k-cycle flash endurance and supports in-circuit debugging via on-chip FINE v2 interface.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F10FLGDNB#U0 | Same RL78/G1E family, identical pinout and peripheral set, but with 96 KB flash and 6 KB RAM - no change to analog subsystem or clock specs | Suitable for larger firmware images requiring more code space or additional data buffers | Select when firmware size exceeds 64 KB or when future feature expansion requires headroom in flash/RAM |
| RL78/G13 R5F10RGLEFA#30 | 64-pin LQFP RL78/G13 MCU with 128 KB flash, 12 KB RAM, and 10-bit ADC (8-channel); lacks integrated PGA and multi-DAC capability | Better for general-purpose control where high-resolution analog signal chain is not required | Choose when cost sensitivity outweighs need for on-chip AFE - requires external op-amps and DACs for equivalent analog performance |
Compared with R5F10FLCDNA#U0, R5F10FLGDNB#U0 offers higher memory capacity without altering analog functionality, while RL78/G13 R5F10RGLEFA#30 trades integrated analog precision for greater code space and lower unit cost - making it suitable only when external analog components are acceptable.

FAQ
What is the maximum operating frequency of the R5F10FLCDNA#U0?
The R5F10FLCDNA#U0 operates at a maximum CPU clock frequency of 32 MHz, achievable using the on-chip high-speed oscillator (HOCO) or an external crystal up to 20 MHz with PLL multiplication. This frequency is fully supported across the entire 1.6–5.5 V supply range and ambient temperature range of −40°C to +85°C, as specified in the RL78/G1E Electrical Characteristics table.
Does the R5F10FLCDNA#U0 include an internal voltage regulator?
Yes, the R5F10FLCDNA#U0 integrates an on-chip LDO regulator that generates a stable 1.8 V or 3.3 V supply from the main VDD rail (1.6–5.5 V). This LDO powers internal analog blocks including the ADC, DAC, and PGA, ensuring consistent performance independent of system rail fluctuations - a key design feature confirmed in Section 2.5.29 (LDO_OUT) of the RL78/G1E Hardware User's Manual.
How many analog input channels does the R5F10FLCDNA#U0 support?
The R5F10FLCDNA#U0 supports 12 analog input channels for its 12-bit ADC, mapped across ports P0, P1, and dedicated analog pins (e.g., MPXIN10/11). These channels are configurable for single-ended or differential acquisition and share the same sample-and-hold circuitry, enabling sequential or grouped conversions as defined in the ANSEL register configuration per the RL78/G1E datasheet.
Can the R5F10FLCDNA#U0 operate from a single 3.3 V supply?
Yes, the R5F10FLCDNA#U0 is fully specified to operate from a single 3.3 V supply across its full temperature range (−40°C to +85°C). Both digital and analog domains function correctly at this voltage, and the internal LDO can be configured to output 3.3 V to power analog peripherals - eliminating need for dual-rail supplies in most applications.
Is the R5F10FLCDNA#U0 pin-compatible with other RL78/G1E variants?
Yes, the R5F10FLCDNA#U0 is pin-compatible with all 64-pin RL78/G1E devices (R5F10FLx series), including R5F10FLGDNB#U0 and R5F10FLEDNA#U0. They share identical pin configuration, electrical characteristics, and peripheral mapping per the RL78/G1E Pin Configuration chapter - enabling drop-in replacement for memory or feature upgrades without PCB revision.
