Renesas R5F212BASNLG#U0

Overview

R5F212BASNLG#U0 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, three UARTs, I²C/SSU, hardware LIN, six timer modules (including 16-bit RD with complementary PWM), and real-time clock - deployed in industrial control panels requiring deterministic timing and mixed-signal interfacing.

For engineers reviewing the R5F212BASNLG#U0 datasheet, R5F212BASNLG#U0 pinout, R5F212BASNLG#U0 application, or R5F212BASNLG#U0 equivalent, key selection criteria include its 64-pin FLGA package (PTLG0064JA-A), -20°C to +85°C N-grade temperature range, on-chip data flash endurance (10,000 erase/write cycles), low-power stop mode (0.65 µA), and hardware LIN support tied to UART0 and Timer RA.

Technical Context

The R5F212BASNLG#U0 implements the R8C/Tiny CPU core with 89 fundamental instructions, 16×16→32-bit multiplier, and multiply-accumulate capability. Its memory architecture separates 96 KB program flash (1,000-cycle endurance) from two 1 KB data flash blocks (10,000-cycle endurance), enabling robust firmware updates and parameter storage without external EEPROM.

Peripheral integration includes Timer RD with reset-synchronous and complementary PWM for three-phase motor control, UART0+Timer RA for LIN 2.0 physical layer compliance, and simultaneous 12-channel ADC sampling with sample-and-hold - all synchronized to a configurable system clock derived from XIN, high-speed on-chip oscillator (trimmable), or 32 kHz XCIN crystal.

FAQ

What is the maximum operating frequency and supply voltage range for the R5F212BASNLG#U0?

The R5F212BASNLG#U0 operates at up to 20 MHz when supplied at 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 guaranteed across its -20°C to +85°C ambient temperature range and directly impact instruction execution time (e.g., 50 ns minimum at 20 MHz).

Does the R5F212BASNLG#U0 include on-chip debug capability?

Yes, the R5F212BASNLG#U0 includes on-chip debug functionality supporting breakpoints, watchpoints, and real-time variable inspection via the on-chip debug interface. This enables full firmware development and validation without external emulators, and is fully compatible with Renesas E1/E20 debuggers and CS+ IDE.

How many erase/write cycles are guaranteed for the data flash in the R5F212BASNLG#U0?

The R5F212BASNLG#U0 guarantees 10,000 erase/write cycles for each of its two 1 KB data flash blocks. This endurance rating is specified under standard operating conditions (VCC = 2.7–5.5 V) and enables reliable storage of calibration data, device configuration, or field-upgradable parameters without external nonvolatile memory.

What peripheral functions are assigned to Port P2 on the R5F212BASNLG#U0?

Port P2 on the R5F212BASNLG#U0 is dedicated to TRD-series timer I/O: P2_0 serves as TRDCLK input, P2_1–P2_7 map to TRDIOA0–TRDIOD1 outputs. These pins provide direct, low-latency control of external three-phase inverter gate drivers - critical for precise timing in motor control applications.

Is the R5F212BASNLG#U0 pin-compatible with other members of the R8C/2B Group?

Yes, all R8C/2B Group MCUs sharing the same package type - including R5F212BASNLG#U0 in PTLG0064JA-A - have identical pin assignments and electrical characteristics. Firmware and PCB layouts are interchangeable across variants differing only in flash size, RAM, or temperature grade, provided the same package is used.
