Product details
Overview
R5F21336GJFP#X4 from Renesas Electronics is a 16-bit R8C/27 Group single-chip microcontroller with 32 KB flash program memory, 1.5 KB RAM, and dual 1 KB data flash blocks. It operates at up to 20 MHz (50 ns min instruction time), supports 12-channel 10-bit A/D conversion, hardware LIN bus via UART0+TimerRA, and runs across -40°C to +85°C. It targets embedded control in industrial sensors and appliance motor interfaces.
For engineers reviewing the R5F21336GJFP#X4 datasheet, R5F21336GJFP#X4 pinout, R5F21336GJFP#X4 application, or R5F21336GJFP#X4 equivalent, key selection criteria include its J-version industrial temperature grade, integrated LIN transceiver capability, 32-pin LQFP package with 25 I/O pins, and dual-block data flash for reliable firmware parameter storage.
Technical Context
The R5F21336GJFP#X4 implements the R8C CPU core with 89 instructions and 1 Mbyte address space. It integrates three clock generation circuits: XIN-based crystal oscillator, high-speed/low-speed on-chip oscillators (with frequency adjustment), and XCIN/XCOUT 32 kHz RTC support - though XCIN/XCOUT is disabled in J version per documentation.
Peripheral integration includes two UARTs (UART0 used for hardware LIN), one I²C interface, one clock-synchronous serial I/O with chip select, Timer RA–RE (including real-time clock in RE), 15 internal + 4 external interrupt sources, and on-chip voltage detection and power-on reset. The device lacks data flash erase/write endurance specification in J-version tables but inherits 10,000-cycle rating from R8C/27 Group baseline.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | R8C 16-bit CISC core with 89 instructions and 20-bit PC; enables compact code and deterministic timing for real-time control loops. |
| Flash Memory | 32 KB program flash + 2 × 1 KB data flash blocks; supports field firmware updates and nonvolatile parameter storage without external EEPROM. |
| A/D Converter | 10-bit resolution, 12 input channels (AN0–AN11); sufficient for multi-sensor monitoring in HVAC or motor drive feedback systems. |
| Operating Temperature | -40°C to +85°C (J version); qualified for industrial environments including factory automation and outdoor equipment enclosures. |
| Supply Voltage | 2.7 V to 5.5 V; compatible with both 3.3 V and 5 V system rails, simplifying power design in mixed-voltage applications. |
| Package | 32-pin LQFP (PLQP0032GB-A); surface-mount footprint with 0.8 mm pitch, suitable for automated PCB assembly and thermal management. |
| Hardware LIN | Integrated LIN 2.0-capable module using UART0 + TimerRA; eliminates need for external LIN transceiver in automotive body electronics nodes. |
Pinout & Package
Package: 32-pin molded-plastic LQFP (PLQP0032GB-A), 7 mm × 7 mm, 0.8 mm pitch, exposed pad not specified.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC / VSS | Power supply inputs | Core logic supply (2.7–5.5 V) and ground; decoupling required within 10 mm of pins for noise immunity in motor-control environments. |
| RESET | Active-low reset input | Asynchronous reset assertion halts CPU and initializes peripherals; requires external pull-up and debouncing for robust operation. |
| XIN / XOUT | Crystal oscillator interface | Supports 1–20 MHz crystals; enables precise timing for UART baud rates and LIN synchronization without external clock source. |
| P0_0–P0_7, P1_0–P1_7, etc. | General-purpose I/O ports | 25 configurable CMOS I/O pins with individual direction registers and optional pull-ups; usable for GPIO, LED drive (N/D only), or peripheral multiplexing. |
| AN0–AN11 | Analog inputs | Dedicated 12-channel ADC inputs with shared pins (e.g., P0_0 = AN7); require analog layout separation from digital traces to maintain 10-bit accuracy. |
| UART0 / UART1 | Serial communication interfaces | Full-duplex UARTs; UART0 paired with TimerRA forms hardware LIN physical layer, reducing software overhead in networked nodes. |
| SCL / SDA | I²C bus interface | Standard-compliant I²C master/slave interface (up to 400 kHz); enables connection to temperature sensors, EEPROMs, or display controllers. |
Key Features
| Feature | Design Value |
|---|---|

| Dual Data Flash Blocks | Two independent 1 KB data flash blocks allow atomic write/erase operations; enables safe parameter storage with rollback capability during firmware updates. |
| Real-Time Clock (RTC) | Timer RE provides calendar-mode RTC with compare-match interrupt; supports time-stamped logging in industrial data recorders without external RTC IC. |
| On-Chip Oscillators | High-speed (adjustable 1–20 MHz) and low-speed (32 kHz) on-chip oscillators eliminate need for external crystals in cost-sensitive designs where ±1% timing tolerance is acceptable. |
| 12-Channel 10-Bit ADC | Simultaneous sampling not supported, but 12-channel scan mode achieves ≤10 µs conversion time; adequate for closed-loop motor current and voltage sensing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F21276JFP | Same R8C/27 Group, 32 KB flash, but no factory-programmed user ROM; requires full firmware load at first boot. | Lacks preloaded bootloader or calibration data; suited for custom firmware-only deployments. | Select R5F21276JFP when full control over initial ROM content is required and factory programming is unnecessary. |
| R5F21336GDFP | D-version variant with identical specs except extended -40°C to +85°C qualification and XCIN/XCOUT RTC support enabled. | XCIN/XCOUT allows external 32.768 kHz crystal for higher RTC accuracy; D version has same temp range but different test screening. | Choose R5F21336GDFP if precise RTC timing (<±20 ppm) is mandatory and external crystal layout is feasible. |
Compared with R5F21336GJFP#X4, R5F21276JFP offers identical peripheral set but no factory programming, while R5F21336GDFP adds XCIN/XCOUT RTC capability at same temperature grade - making the JFP#X4 optimal for cost-sensitive, drop-in LIN node replacements requiring guaranteed factory firmware.

FAQ
What is the maximum operating frequency and corresponding supply voltage range for R5F21336GJFP#X4?
R5F21336GJFP#X4 supports a maximum operating frequency of 20 MHz at VCC = 3.0 V to 5.5 V. This rating applies to all versions except K (16 MHz) and N/D (10 MHz or 5 MHz at lower voltages). The J version's -40°C to +85°C range is fully validated at 20 MHz within this voltage window, enabling high-speed UART and LIN communication without derating.
Does R5F21336GJFP#X4 include hardware LIN functionality, and how is it implemented?
Yes, R5F21336GJFP#X4 integrates hardware LIN 2.0 support using UART0 combined with TimerRA for sync-break generation and detection. This offloads LIN protocol timing from firmware, ensuring deterministic frame transmission and reducing CPU utilization by up to 35% compared to software-implemented LIN stacks.
What are the data flash endurance and block structure of R5F21336GJFP#X4?
R5F21336GJFP#X4 contains two independent 1 KB data flash blocks, each rated for 10,000 erase/write cycles. These blocks support atomic sector erase and byte-wise programming, enabling safe storage of calibration data, device configuration, or runtime parameters with built-in wear-leveling in application firmware.
Is XCIN/XCOUT functionality available on R5F21336GJFP#X4 for real-time clock operation?
No, XCIN/XCOUT is explicitly disabled in the J version per Renesas documentation. R5F21336GJFP#X4 relies on its internal low-speed oscillator or XIN-based clock for Timer RE real-time clock operation. For external 32.768 kHz crystal support, the D or N version (e.g., R5F21336GDFP) must be selected.
How many general-purpose I/O pins does R5F21336GJFP#X4 provide, and what are their key electrical characteristics?
R5F21336GJFP#X4 provides 25 programmable I/O pins (P0_0–P0_7, P1_0–P1_7, P3_1, P3_3–P3_7, P4_5, P5_3, P5_4) plus 3 dedicated input-only pins (P4_2, P4_6, P4_7). All I/Os support CMOS levels, individual direction control, and optional weak pull-ups - enabling direct interface with switches, LEDs, and digital sensors without external components.
