Overview

R5F212B7SNLG#W4 from Renesas Electronics is a 16-bit R8C/Tiny Series MCU in the R8C/2B Group, featuring 48 KB flash program memory, 1 KB × 2 on-chip data flash, 2.5 KB RAM, and operation at up to 20 MHz (V_CC = 3.0–5.5 V). It integrates 12-channel 10-bit A/D, dual 8-bit D/A, three UARTs, I²C/SSU, hardware LIN, and six timer modules - deployed in consumer appliance control and industrial sensor interface applications.

For engineers reviewing the R5F212B7SNLG#W4 datasheet, R5F212B7SNLG#W4 pinout, R5F212B7SNLG#W4 application, or R5F212B7SNLG#W4 equivalent, key selection criteria include its 64-pin FLGA package (PTLG0064JA-A), -20°C to +85°C N-version temperature grade, on-chip data flash endurance (10,000 erase/write cycles), low-power stop mode (0.65 µA), and R8C CPU core instruction execution time of 50 ns at 20 MHz.

Technical Context

The R5F212B7SNLG#W4 implements the R8C/Tiny CPU core with 89 fundamental instructions, 16×16→32-bit multiplier, and multiply-accumulate capability. Its memory architecture separates 48 KB program flash (1,000-cycle endurance) from two 1 KB data flash blocks (10,000-cycle endurance), enabling reliable parameter storage without external EEPROM.

Peripheral integration includes Timer RD (16-bit × 2, 6-pin PWM, complementary three-phase output), Timer RC (16-bit, 4 capture/compare registers), and hardware LIN using UART0 and Timer RA - all mapped to dedicated pins in the 64-pin FLGA package with configurable I/O pull-up resistors and high-current drive capability on eight ports.

FAQ

What is the maximum operating frequency and supply voltage range for the R5F212B7SNLG#W4?

The R5F212B7SNLG#W4 operates at up to 20 MHz when supplied at V_CC = 3.0–5.5 V. At reduced frequencies (10 MHz, 5 MHz), it supports down to 2.7 V and 2.2 V respectively - enabling flexible power rail design across battery and line-powered systems. This specification is confirmed in Tables 1.3 and 1.4 of the R8C/2B Group datasheet (Rev.2.10).

Does the R5F212B7SNLG#W4 support hardware LIN communication?

Yes, the R5F212B7SNLG#W4 includes a dedicated hardware LIN module implemented using UART0 and Timer RA, compliant with LIN 2.1 protocol. This offloads LIN frame generation and checksum calculation from firmware, reducing CPU utilization and improving timing accuracy - a confirmed feature in Section 1.1.1 and Table 1.4 of the official documentation.

What is the endurance rating of the on-chip data flash in the R5F212B7SNLG#W4?

The R5F212B7SNLG#W4 features two 1 KB data flash blocks rated for 10,000 erase/write cycles - significantly higher than its 1,000-cycle program ROM endurance. This allows frequent updates of calibration parameters or runtime configuration without premature wear-out, as specified in Table 1.4 under "Flash Memory" for the R8C/2B Group.

Which package type does the R5F212B7SNLG#W4 use, and what are its mechanical dimensions?

The R5F212B7SNLG#W4 uses the 64-pin FLGA package PTLG0064JA-A: 0.65 mm pin pitch, 6 mm × 6 mm body size, and 0.8 mm max height. This land-grid array format enables high I/O density and fine-pitch routing, as defined in Figure 1.2 and Table 1.6 of the R8C/2B Group datasheet (REJ03B0182-0210).

How many analog input channels and what resolution does the A/D converter offer on the R5F212B7SNLG#W4?

The R5F212B7SNLG#W4 integrates a 10-bit successive-approximation A/D converter with 12 input channels (AN0–AN11), including sample-and-hold functionality. All channels are accessible via P0 and P1 port pins, supporting simultaneous sampling for multi-sensor applications - as detailed in Table 1.4 under "A/D Converter" for the R8C/2B Group.
