Product details
Overview
R5F212L4SDFP#X6 from Renesas Electronics is a 16-bit R8C/Tiny Series microcontroller in the R8C/2L Group, designed for embedded control in cost-sensitive industrial and consumer applications. It features 16 KB flash program memory, 1 KB × 2 on-chip data flash (10,000 write/erase cycles), 1.5 KB RAM, and operates from 2.2 V to 5.5 V at up to 20 MHz. Its integrated peripherals include dual UARTs, hardware LIN module, 10-bit 9-channel A/D converter, and four advanced timers (RA–RD) supporting PWM, capture/compare, and three-phase motor control.
For engineers reviewing the R5F212L4SDFP#X6 datasheet, R5F212L4SDFP#X6 pinout, R5F212L4SDFP#X6 application, or R5F212L4SDFP#X6 equivalent, key selection considerations include its -40°C to +85°C industrial temperature grade (D version), 32-pin LQFP package (PLQP0032GB-A), on-chip debug capability, low-power stop mode (0.7 µA), and dedicated data flash for parameter storage or firmware updates.
Technical Context
The R5F212L4SDFP#X6 implements the R8C/Tiny CPU core with 89 fundamental instructions, 16×16→32-bit multiplier, and multiply-accumulate capability. It supports single-chip operation across a 1 Mbyte address space and executes instructions in as little as 50 ns at 20 MHz with 3.0–5.5 V supply.
Its peripheral set includes Timer RD with reset-synchronous and complementary PWM modes for three-phase motor drive, hardware LIN bus support tied to UART0 and Timer RA, and dual UART interfaces with clock-synchronous serial I/O capability. The A/D converter includes sample-and-hold for accurate multi-channel acquisition.

FAQ
What is the maximum operating frequency of the R5F212L4SDFP#X6 and under what voltage conditions?
The R5F212L4SDFP#X6 achieves a maximum operating frequency of 20 MHz when supplied with VCC between 3.0 V and 5.5 V. At 2.7–5.5 V, it supports 10 MHz operation, and at 2.2–5.5 V (with A/D limited to 2.7–5.5 V), it runs at 5 MHz. These ratings are specified in the R8C/2L Group datasheet Rev.1.10 and reflect guaranteed timing margins across the D-grade temperature range.
Does the R5F212L4SDFP#X6 include on-chip debug capability?
Yes, the R5F212L4SDFP#X6 includes full on-chip debug functionality, enabling real-time breakpoint setting, register inspection, and flash programming via the on-chip debug interface. This capability is documented in Section 1.1.2 of the R8C/2L Group specification and supports development without external emulators.
How many A/D converter channels does the R5F212L4SDFP#X6 support, and what is their resolution?
The R5F212L4SDFP#X6 integrates a 10-bit successive-approximation A/D converter with nine input channels (AN0–AN7, AN11). It includes a sample-and-hold circuit to maintain signal integrity during conversion, and all channels are accessible via dedicated pins on Port P0 and Port P1 as defined in Table 1.7 of the official datasheet.
What is the purpose of the two 1 KB data flash blocks in the R5F212L4SDFP#X6?
The two 1 KB data flash blocks in the R5F212L4SDFP#X6 provide 10,000 write/erase cycles for nonvolatile storage of calibration coefficients, device-specific configuration, runtime parameters, or firmware update staging. Unlike program flash, these blocks can be rewritten independently during application execution using the on-board flash rewrite function.
Is the R5F212L4SDFP#X6 pin-compatible with other members of the R8C/2L Group?
Yes, all R8C/2L Group devices-including R5F212L2SDFP, R5F212L4SDFP, and R5F212L4SNFP-share identical 32-pin LQFP (PLQP0032GB-A) packaging and pin assignments. Function mapping is consistent across variants; differences are limited to memory size, temperature grade, and data flash presence, not pinout or peripheral register layout.
