Renesas R5F212G6SDFP#U0

Overview

R5F212G6SDFP from Renesas Electronics is a 16-bit R8C/Tiny Series microcontroller with 32 KB Flash ROM, 1 KB RAM, and 27 CMOS I/O ports in a 32-pin LQFP package. It features an on-chip high-speed oscillator (up to 8 MHz), real-time clock (Timer RE), LIN hardware module, UART0/UART2 serial interfaces, and operates from -40°C to +85°C for industrial applications including power meters and home appliances.

For engineers reviewing the R5F212G6SDFP datasheet, R5F212G6SDFP pinout, R5F212G6SDFP application, or R5F212G6SDFP equivalent, key selection considerations include its D-version extended temperature range, integrated LIN protocol support, low-power stop mode (0.7 µA), Flash programming endurance (100 cycles), and compatibility with Renesas' on-chip debug and flash rewrite functions.

Technical Context

The R5F212G6SDFP implements the R8C/Tiny CPU core with 89 fundamental instructions, 16×16→32-bit multiplier, and multiply-accumulate capability. Its memory map spans 1 Mbyte, with Flash ROM starting at 08000h and RAM at 00400h, supporting single-chip operation without external memory.

Peripheral integration includes four timers (RA, RB, RE, RF), two comparators shared with voltage monitors, dual UARTs with clock-synchronous serial I/O, and a dedicated hardware LIN module using Timer RA and UART0 - all controlled via dedicated SFRs mapped to addresses 0000h–00FFh.

FAQ

What is the maximum system clock frequency supported by the R5F212G6SDFP?

The R5F212G6SDFP supports a maximum system clock frequency of 8 MHz when operating within the 2.7 V to 5.5 V supply range. At lower voltages (2.2 V to 5.5 V), the maximum rated frequency is 4 MHz. This specification is defined in the electrical characteristics section of the R8C/2G Group datasheet (REJ03B0223-0100), and the on-chip high-speed oscillator includes frequency adjustment capability to maintain stability across voltage and temperature variations.

Does the R5F212G6SDFP include hardware support for LIN communication?

Yes, the R5F212G6SDFP integrates a dedicated hardware LIN module compliant with LIN 2.0/2.1 standards. It combines UART0 and Timer RA to handle LIN frame generation, synchronization, checksum calculation, and error detection without CPU intervention. This capability is documented in Section 1.1.2 and Figure 1.2 of the R8C/2G Group datasheet, and enables reliable communication in automotive body electronics and industrial sensor networks.

What are the power consumption values for R5F212G6SDFP in low-power modes?

The R5F212G6SDFP achieves 23 µA in wait mode (with low-speed on-chip oscillator active at 3 V) and 0.7 µA in stop mode (with BGR trimming circuit disabled at 3 V). These values are measured under specified conditions in the "Current Consumption" section of the R8C/2G Group datasheet (REJ03B0223-0100, Page 2). The MCU supports multiple low-power states to extend battery life in portable or energy-harvesting applications.

How much Flash memory and RAM does the R5F212G6SDFP provide?

The R5F212G6SDFP provides 32 KB of on-chip Flash ROM (mapped from address 08000h to 0FFFFh) and 1 KB of RAM (mapped from address 00400h to 007FFh). These memory sizes are confirmed in Table 1.2 ("Product List for R8C/2G Group") and Figure 3.1 ("Memory Map") of the official Renesas datasheet REJ03B0223-0100. The Flash supports 100 program/erase cycles and includes ROM code protection.

What package type and pin count does the R5F212G6SDFP use?

The R5F212G6SDFP uses a 32-pin LQFP package designated PLQP0032GB-A (formerly 32P6U-A), measuring 7 mm × 7 mm with 0.8 mm lead pitch. This package is explicitly listed in Table 1.2 and Figure 1.3 ("Pin Assignment") of the R8C/2G Group datasheet (REJ03B0223-0100). It supports surface-mount assembly and provides 27 configurable CMOS I/O ports plus dedicated power, reset, and oscillator pins.
