Renesas R5F212BASNFA#X6

Overview

R5F212BASNFA#X6 from Renesas Electronics is a 16-bit R8C/Tiny Series microcontroller in the R8C/2B Group, featuring 96 KB flash program memory, 1 KB × 2 on-chip data flash, 7 KB RAM, and operation up to 20 MHz at 3.0–5.5 V. It integrates 12-channel 10-bit ADC, dual 8-bit DACs, six flexible timers (including three-phase PWM-capable Timer RD), LIN hardware module, and UART/SSU/I²C serial interfaces. It targets embedded control in consumer appliances requiring low-power operation and mixed-signal integration.

For engineers reviewing the R5F212BASNFA#X6 datasheet, R5F212BASNFA#X6 pinout, R5F212BASNFA#X6 application, or R5F212BASNFA#X6 equivalent, key selection criteria include its 64-pin LQFP package with 0.8 mm pitch, -20°C to +85°C industrial temperature grade (N version), on-chip data flash for parameter storage, and hardware LIN support tied to UART0 and Timer RA - all confirmed in Renesas document REJ03B0182-0210.

Technical Context

The R5F212BASNFA#X6 implements the R8C/Tiny CPU core with 89 fundamental instructions and a dedicated 16×16→32-bit multiplier for efficient signal processing. Its clock system includes XIN/XOUT (up to 20 MHz), XCIN/XCOUT (32 kHz real-time clock), and adjustable high-speed/low-speed on-chip oscillators with selectable frequency dividers (1/2/4/8/16).

Peripheral integration centers on deterministic timing control: Timer RD supports reset-synchronous and complementary PWM for motor drive, Timer RC provides 4 capture/compare registers for encoder input, and the LIN module uses UART0 with automatic sync-break detection and checksum generation per ISO 9141-2 and SAE J2602 standards.

FAQ

What is the maximum operating frequency and supply voltage range for R5F212BASNFA#X6?

The R5F212BASNFA#X6 operates at up to 20 MHz when supplied at 3.0–5.5 V, 10 MHz at 2.7–5.5 V, and 5 MHz at 2.2–5.5 V. Its minimum instruction execution time is 50 ns under the 20 MHz/3.0–5.5 V condition. These ratings are defined in Renesas document REJ03B0182-0210, Tables 1.3 and 1.4, and apply specifically to the R5F212BASNFA#X6 variant.

Does R5F212BASNFA#X6 include on-chip data flash, and what is its endurance?

Yes, the R5F212BASNFA#X6 includes 1 KB × 2 blocks of on-chip data flash, rated for 10,000 erase/write cycles. This is distinct from its 96 KB program flash (1,000-cycle endurance) and enables reliable storage of calibration data, device configuration, or field-upgradable parameters without external nonvolatile memory. Confirmed in Table 1.4 of REJ03B0182-0210.

Which package type and pin pitch does R5F212BASNFA#X6 use?

R5F212BASNFA#X6 uses the PLQP0064GA-A package: a 64-pin LQFP with 0.8 mm pin pitch and 14 mm × 14 mm body size. This is explicitly identified in Figure 1.2 and Table 1.6 of Renesas document REJ03B0182-0210, where "FA" denotes this specific footprint variant.

What peripheral features distinguish R5F212BASNFA#X6 from the R8C/2A Group?

The R5F212BASNFA#X6 belongs to the R8C/2B Group and includes 1 KB × 2 on-chip data flash - a feature absent in all R8C/2A Group devices like R5F212AASNFA#X6. All other peripherals, pinout, and electrical specifications are identical between corresponding R8C/2A and R8C/2B parts, as stated in Section 1.1 of REJ03B0182-0210.

Is hardware LIN support available on R5F212BASNFA#X6, and how is it implemented?

Yes, R5F212BASNFA#X6 includes a hardware LIN module compliant with ISO 9141-2 and SAE J2602, implemented using UART0 and Timer RA. This offloads LIN protocol framing, checksum calculation, and sync-break detection from firmware, ensuring deterministic timing and reduced CPU overhead. Details are in Section 1.1.2 and Table 1.4 of REJ03B0182-0210.
