Product details
Overview
R5F21356MNFP#V0 from Renesas Electronics is a 16-bit R8C CPU core microcontroller with 32 KB program flash, 2.5 KB RAM, and 4 KB data flash (1 KB × 4 blocks) supporting background operation (BGO). It delivers 50 ns minimum instruction execution at 20 MHz (VCC = 2.7–5.5 V), integrates dual 8-bit timers (RA/RB), dual 16-bit timers (RC/RD), real-time clock (RE), 10-bit × 12-channel ADC, dual 8-bit DACs, LIN hardware module, and I²C/UART/SSU serial interfaces. It targets embedded control in consumer audio equipment and office automation systems.
For engineers reviewing the R5F21356MNFP#V0 datasheet, R5F21356MNFP#V0 pinout, R5F21356MNFP#V0 application, or R5F21356MNFP#V0 equivalent, key selection criteria include its -20°C to +85°C operating range (N version), 52-pin LQFP package (PLQP0052JA-A), integrated voltage detection circuitry, low-power wait/stop modes (3.5 µA / 2.0 µA), and on-chip debug capability with flash rewrite support.
Technical Context
The R5F21356MNFP#V0 implements the R8C CPU core with 89 fundamental instructions, 1 Mbyte address space, and hardware multiplier (16×16→32 bits) plus multiply-accumulate (16×16+32→32 bits). Its clock system includes four independent sources: XIN/XOUT (up to 20 MHz), XCIN/XCOUT (32 kHz), high-speed on-chip oscillator (frequency-adjustable), and low-speed on-chip oscillator - all selectable via programmable frequency dividers (1/2/4/8/16).
Peripheral integration centers on deterministic real-time control: Timer RD supports complementary PWM for three-phase motor drive (6-pin output, triangular/sawtooth modulation), while the LIN module leverages Timer RA and UART0 for hardware protocol compliance. The DTC (Data Transfer Controller) provides single-channel DMA with 33 activation sources and repeat/normal transfer modes, reducing CPU overhead during ADC sweeps or serial transfers.

Pinout & Package
Package: 52-pin LQFP (PLQP0052JA-A), 10 mm × 10 mm body, 0.65 mm pitch, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC/AVCC (Pin 12) | Power supply input | Main digital supply (1.8–5.5 V); AVCC powers ADC/DAC analog circuitry - requires local decoupling to AVSS |

|---|---|
| Background Operation (BGO) | Data flash erasure/programming proceeds concurrently with CPU code execution - enables firmware updates without halting real-time tasks |
| Hardware LIN Module | Full LIN 2.0/2.1 compliance using dedicated UART0 and Timer RA resources - eliminates software bit-banging overhead and timing jitter |
| Complementary PWM (Timer RD) | Generates synchronized three-phase waveforms (6-pin output) with dead-time insertion and triangular/sawtooth modulation - suitable for BLDC motor control |
| Voltage Detection Circuit | Configurable voltage monitor with Power-on Reset and selectable detection levels (VD0/VD1) - ensures reliable startup and brown-out recovery |
