Renesas R5F212L4SDFP#V2

Overview

R5F212L4SDFP#V2 from Renesas Electronics is a 16-bit R8C/Tiny Series microcontroller in the R8C/2L Group, featuring 16 KB flash program memory, 1 KB × 2 on-chip data flash, and 1.5 KB RAM. It operates at up to 20 MHz (VCC = 3.0–5.5 V), supports -40°C to +85°C ambient temperature (D version), and integrates UART0/UART2, hardware LIN, 10-bit × 9-channel A/D converter, and four advanced timers (RA–RD) - used in embedded control for home appliances and industrial sensors.

For engineers reviewing the R5F212L4SDFP#V2 datasheet, R5F212L4SDFP#V2 pinout, R5F212L4SDFP#V2 application, or R5F212L4SDFP#V2 equivalent, key selection considerations include its D-grade temperature rating, dual-block data flash endurance (10,000 erase/write cycles), 32-pin LQFP package (PLQP0032GB-A), and integrated LIN physical layer support via UART0 and timer RA.

Technical Context

The R5F212L4SDFP#V2 implements the R8C/Tiny CPU core with 89 fundamental instructions, 16×16→32-bit multiplier, and multiply-accumulate capability. Its memory architecture includes separate program ROM and dual 1-KB data flash blocks - enabling reliable firmware updates and parameter storage without external EEPROM.

Peripheral integration centers on deterministic real-time control: Timer RD delivers three-phase PWM with complementary outputs and sawtooth/triangular wave modulation; the hardware LIN module uses UART0 and timer RA for ISO 9141-2/SAE J2602-compliant communication; and the 10-bit A/D converter includes sample-and-hold across all 9 channels for accurate sensor interfacing.

FAQ

What is the maximum operating frequency of the R5F212L4SDFP#V2 and under what voltage conditions?

The R5F212L4SDFP#V2 achieves a maximum operating frequency of 20 MHz when supplied with VCC = 3.0 V to 5.5 V. At lower voltages, its speed scales: 10 MHz at VCC = 2.7–5.5 V, and 5 MHz at VCC = 2.2–5.5 V (with A/D converter functional only above 2.7 V). These ratings are specified in Renesas document REJ03B0219-0110 Rev.1.10.

Does the R5F212L4SDFP#V2 include on-chip data flash, and how many erase/write cycles does it support?

Yes, the R5F212L4SDFP#V2 includes two 1 KB on-chip data flash blocks supporting 10,000 erase/write cycles each. This is distinct from its 16 KB program flash (rated for 1,000 cycles) and enables reliable storage of calibration data, device configuration, or field-upgradable parameters without external memory. The specification is confirmed in Table 1.4 of the R8C/2L Group datasheet.

What peripheral functions enable LIN bus communication on the R5F212L4SDFP#V2?

The R5F212L4SDFP#V2 implements hardware LIN 2.1/SAE J2602 communication using UART0 combined with timer RA for baud rate generation and frame timing. This integrated LIN module eliminates the need for an external LIN transceiver in slave-node applications such as automotive door modules or HVAC actuators, as documented in Section 1.1.2 of REJ03B0219-0110.

What is the operating temperature range certified for the R5F212L4SDFP#V2, and which quality grade does it carry?

The R5F212L4SDFP#V2 is rated for -40°C to +85°C ambient operation (D version) and carries the "Standard" quality grade per Renesas classification - intended for industrial equipment, office automation, and consumer appliances. It is not qualified for safety-critical or life-support applications, as stated in Section 7 of the Renesas general notice.

How many analog input channels does the R5F212L4SDFP#V2 support, and what is their resolution and key feature?

The R5F212L4SDFP#V2 supports nine 10-bit analog input channels (AN2, AN4–AN11) with integrated sample-and-hold circuitry. This allows simultaneous sampling across multiple channels for accurate phase-correlated measurements in motor control or sensor fusion applications, as specified in Table 1.4 of the R8C/2L Group datasheet.
