Product details
Overview
R5F21262SYFP#V2 from Renesas Electronics is a 16-bit R8C/26 Group single-chip microcontroller featuring an 8 KB flash program memory, 512 bytes RAM, 12-channel 10-bit A/D converter, dual UART interfaces, and hardware LIN support - deployed in consumer appliance control, office equipment motor management, and automotive body electronics subsystems.
For engineers reviewing the R5F21262SYFP#V2 datasheet, R5F21262SYFP#V2 pinout, R5F21262SYFP#V2 application, or R5F21262SYFP#V2 equivalent, this page delivers verified technical context, validated pin functions, real-world use cases, and confirmed alternative options for embedded firmware development and BOM optimization.
Technical Context
The R5F21262SYFP#V2 implements the R8C CPU core with 89 fundamental instructions and executes at 50 ns minimum instruction time (20 MHz XIN, 3.0–5.5 V). It integrates three independent clock generation circuits: XIN-based crystal oscillator, high-speed/low-speed on-chip oscillators (with frequency adjustment), and XCIN-based 32 kHz RTC oscillator (N/D version only).
Peripheral integration includes Timer RA/RB (8-bit × 2), Timer RC (16-bit input capture/output compare), Timer RE (real-time clock + compare match), two UART channels, one I²C bus interface, one clock-synchronous serial I/O with chip select, and hardware LIN module leveraging Timer RA and UART0 - all mapped to a fixed 32-pin LQFP package with confirmed pin assignments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | R8C 16-bit CISC core with 89 instructions; enables compact firmware and deterministic timing for real-time control loops. |
| Flash Memory | 8 KB program ROM; supports in-system programming and 100 erase/write cycles - sufficient for mid-complexity appliance firmware. |
| RAM | 512 bytes; allocated for stack, variables, and interrupt context storage in single-chip operation without external memory. |
| A/D Converter | 10-bit resolution, 12 analog inputs; provides sufficient precision for sensor monitoring (e.g., temperature, voltage, potentiometer feedback). |
| Timers | Timer RA/RB (8-bit), Timer RC (16-bit input capture/output compare), Timer RE (RTC + compare match); supports PWM generation, pulse-width measurement, and time-stamped event logging. |
| Serial Interfaces | UART0/UART1 (full-duplex), I²C bus, clock-synchronous serial I/O with chip select, and hardware LIN - enables multi-protocol communication with sensors, displays, and ECUs. |
| Operating Voltage | 2.2–5.5 V (N/D version); supports wide-input power rails common in battery-backed or unregulated industrial supplies. |

Pinout & Package
Package: 32-pin molded-plastic LQFP (PLQP0032GB-A), 7 mm × 7 mm, 0.8 mm pitch - compatible with standard surface-mount reflow processes and automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC / VSS | Power supply input / ground | Primary digital power domain (2.2–5.5 V); decoupling required per Renesas layout guidelines to ensure noise immunity. |
| AVCC / AVSS | Analog power supply | Dedicated analog domain for A/D converter; requires separate low-noise filtering from digital VCC to minimize quantization error. |
| RESET | Active-low reset input | Asynchronous hardware reset; must be held low ≥100 ns after power stabilization to guarantee reliable initialization. |
| XIN / XOUT | Crystal oscillator input/output | Supports 5–20 MHz crystal or ceramic resonator; enables precise timing for UART baud rate generation and real-time control. |
| AN0–AN11 | Analog input channels | 12 single-ended inputs for 10-bit A/D conversion; internally multiplexed - software-controlled channel selection required. |
| TXD0 / RXD0 | UART0 transmit/receive | Full-duplex asynchronous serial interface; supports standard baud rates up to 1 Mbps (at 20 MHz XIN) for host diagnostics or display control. |
| P0_0–P0_7 | General-purpose I/O port | 8-bit CMOS bidirectional port with programmable pull-up; usable as GPIO, A/D inputs (AN0–AN7), or TREO output (Timer RE). |
| INT0 / INT1 / INT3 | External interrupt inputs | Edge-triggered interrupt sources; enable responsive event handling (e.g., button press, safety interlock, encoder zero-crossing). |
Key Features
| Feature | Design Value |
|---|---|
| Hardware LIN Module | Integrated LIN 2.0/2.1 transceiver logic using Timer RA and UART0 - eliminates external LIN transceiver IC in body control modules. |
| Real-Time Clock (RTC) | Timer RE with 32 kHz XCIN input support (D version); provides calendar/timekeeping without external RTC IC or continuous CPU polling. |
| Low-Power Stop Mode | 0.7 µA typical current at 3.0 V - enables battery-powered remote controls and sensor nodes with multi-year standby life. |
| On-Chip Oscillators | High-speed (adjustable 1–20 MHz) and low-speed (125 kHz) RC oscillators - allow clock source redundancy and fast wake-up from stop mode. |
| LED Drive Capability | P1_0–P1_7 support direct LED sink/source drive (D version); reduces BOM count in status indicator designs without external drivers. |
| Interrupt Priority Levels | 7-level nested priority scheme with IPL register - ensures deterministic response to critical events (e.g., overcurrent, watchdog timeout) in safety-critical firmware. |
