Renesas R5F212D7SDFP#V2

Overview

R5F212D7SDFP#V2 from Renesas Electronics is an 80-pin LQFP microcontroller in the R8C/2D Group, featuring the R8C/Tiny Series CPU core, 48 KB flash program memory, 1 KB × 2 on-chip data flash, and 2.5 KB RAM. It operates from 2.2 V to 5.5 V, supports −40°C to +85°C ambient temperature (D version), and integrates 20-channel 10-bit A/D, dual 8-bit D/A, six timers (including three-phase PWM-capable Timer RD), UART×3, I²C/SSU, and hardware LIN interface - deployed in industrial motor control and appliance power management systems.

For engineers reviewing the R5F212D7SDFP#V2 datasheet, R5F212D7SDFP#V2 pinout, R5F212D7SDFP#V2 application, or R5F212D7SDFP#V2 equivalent, key selection criteria include its −40°C to +85°C industrial temperature rating, dual-block data flash for firmware update resilience, integrated LIN physical layer support via UART0+Timer RA, and 80-pin LQFP package with 71 programmable CMOS I/Os including 8 high-current drive pins.

Technical Context

The R5F212D7SDFP#V2 implements the R8C/Tiny CPU core with 89 fundamental instructions, 16×16→32-bit multiplier, and multiply-accumulate capability. Its clock system includes XIN (up to 20 MHz), XCIN (32 kHz real-time clock), and adjustable high-speed on-chip oscillator - all feeding into a programmable frequency divider (1/2/4/8/16) and low-power modes (wait: 2.1 µA, stop: 0.65 µA at 3.0 V).

Peripheral integration centers on deterministic timing control: Timer RD provides reset-synchronous or complementary three-phase PWM (6-pin output), Timer RC offers 4 capture/compare registers for encoder input or PWM generation, and the LIN module uses UART0 with Timer RA for baud rate modulation and sync pulse generation - all coordinated under 7-level interrupt priority with 28 total sources (5 external, 23 internal).

FAQ

What is the maximum operating frequency of the R5F212D7SDFP#V2?

The R5F212D7SDFP#V2 supports a maximum XIN clock frequency of 20 MHz at VCC = 3.0 to 5.5 V, delivering a minimum instruction execution time of 50 ns. At lower supply voltages (2.2–2.7 V), the maximum supported frequency reduces to 5 MHz or 10 MHz per datasheet specifications - ensuring reliable operation across its full 2.2 V to 5.5 V supply range.

Does the R5F212D7SDFP#V2 include on-chip debug capability?

Yes, the R5F212D7SDFP#V2 includes on-chip debug functionality supporting real-time emulation, breakpoint setting, and memory inspection via dedicated debug interface pins. This enables full firmware development and validation without requiring external debug probes beyond standard Renesas E1/E20 emulators.

How many analog input channels does the R5F212D7SDFP#V2 support?

The R5F212D7SDFP#V2 integrates a 10-bit A/D converter with 20 dedicated analog input channels (AN0–AN19), all sharing a common sample-and-hold circuit and supporting sweep mode for sequential conversion - enabling simultaneous monitoring of multiple sensors in motor control or appliance applications.

What is the purpose of the dual 1 KB data flash blocks in the R5F212D7SDFP#V2?

The dual 1 KB data flash blocks in the R5F212D7SDFP#V2 provide independent, wear-leveled nonvolatile storage for firmware parameters, calibration data, or event logs. One block can be rewritten while the other remains active - ensuring data integrity during field updates and supporting up to 10,000 erase/write cycles per block.

Is the R5F212D7SDFP#V2 pin-compatible with other R8C/2D Group devices?

Yes, all R8C/2D Group MCUs in the PLQP0080KB-A (80-pin LQFP) package - including R5F212D7SDFP#V2, R5F212D8SDFP#V2, and R5F212DASDFP#V2 - share identical pin assignments, electrical characteristics, and peripheral mappings. Firmware and PCB layouts are interchangeable across this family when memory and peripheral usage remain within the target device's capacity.
