Renesas R5F212B7SNLG#U0

Overview

R5F212B7SNLG#U0 from Renesas Electronics is a 16-bit R8C/Tiny Series microcontroller 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, six timer modules (including 16-bit RD with complementary PWM), and operates from –20°C to +85°C in a 64-pin FLGA package. It targets embedded control in consumer audio and office equipment.

For engineers reviewing the R5F212B7SNLG#U0 datasheet, R5F212B7SNLG#U0 pinout, R5F212B7SNLG#U0 application, or R5F212B7SNLG#U0 equivalent, key selection criteria include on-chip data flash endurance (10,000 write/erase cycles), low-power stop mode current (0.65 µA), 64-pin FLGA footprint (PTLG0064JA-A), and hardware LIN support via UART0 and Timer RA - all confirmed for this exact variant.

Technical Context

The R5F212B7SNLG#U0 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), high-speed/low-speed on-chip oscillators (with frequency adjustment), and 32 kHz XCIN/XCOUT for real-time clock operation.

Peripheral integration centers on deterministic timing control: Timer RD provides reset-synchronous and complementary PWM for motor drive, while Timer RC and RF support input capture and output compare for encoder interfacing. The LIN module is implemented in hardware using UART0 and Timer RA, enabling compliant physical layer communication without software overhead.

FAQ

What is the maximum operating frequency and supply voltage range for the R5F212B7SNLG#U0?

The R5F212B7SNLG#U0 operates at up to 20 MHz when supplied at V_CC = 3.0–5.5 V. At lower voltages, maximum frequency scales: 10 MHz at 2.7–5.5 V, and 5 MHz at 2.2–5.5 V. These ratings are validated across the full –20°C to +85°C ambient temperature range specified for the N-version R5F212B7SNLG#U0.

Does the R5F212B7SNLG#U0 support hardware LIN communication?

Yes, the R5F212B7SNLG#U0 includes a dedicated hardware LIN module implemented using UART0 and Timer RA, supporting LIN 2.0/2.1 protocol without CPU intervention. This enables reliable, low-overhead communication in automotive body electronics and industrial control networks where R5F212B7SNLG#U0 serves as a slave node.

What package type and pin count does the R5F212B7SNLG#U0 use?

The R5F212B7SNLG#U0 uses a 64-pin FLGA package (PTLG0064JA-A) with 0.65 mm pitch and 6 mm × 6 mm body size. This compact, surface-mount package supports high-density PCB layouts and is RoHS-compliant. Pin assignments match the R8C/2B Group specification and are documented in Figures 1.5 and Tables 1.7–1.8 of the R8C/2A,2B datasheet.

How many A/D and D/A channels does the R5F212B7SNLG#U0 integrate?

The R5F212B7SNLG#U0 integrates a 10-bit A/D converter with 12 input channels (AN0–AN11) and two independent 8-bit D/A converters (DA0, DA1). All A/D inputs are accessible via P0_0–P0_7 and P1_0–P1_3, enabling simultaneous sampling of sensors, potentiometers, or thermal monitors in systems using R5F212B7SNLG#U0 as the central analog interface.

What low-power modes are available on the R5F212B7SNLG#U0, and what are their typical current draws?

The R5F212B7SNLG#U0 supports wait mode (2.1 µA at V_CC = 3.0 V with 32 kHz RTC active) and stop mode (0.65 µA at V_CC = 3.0 V). Both modes retain RAM content and allow wake-up via external interrupt or RTC alarm. These modes are fully supported in the N-version R5F212B7SNLG#U0 and validated across its rated temperature range.
