Product details
Overview
R5F2136ACNFP#30 from Renesas Electronics is a 16-bit R8C CPU core microcontroller with 96 KB program ROM, 8 KB data flash (4 × 1 KB blocks), and 8 KB RAM, operating at up to 20 MHz (VCC = 2.7–5.5 V). It integrates UART×3, I²C, LIN, 10-bit ADC (12 channels), dual 8-bit DACs, six timer modules (including complementary PWM-capable Timer RD), and background operation (BGO) for in-application data flash reprogramming - deployed in consumer audio equipment and office automation systems.
For engineers reviewing the R5F2136ACNFP#30 datasheet, R5F2136ACNFP#30 pinout, R5F2136ACNFP#30 application, or R5F2136ACNFP#30 equivalent, key selection criteria include its 64-pin LQFP (PLQP0064KB-A) package, −20°C to +85°C industrial temperature grade, integrated voltage detection with power-on reset, and real-time clock (Timer RE) with calendar mode - all critical for embedded control in cost-sensitive, low-power appliance designs.
Technical Context
The R5F2136ACNFP#30 implements the R8C CPU core with 89 fundamental instructions, 1 Mbyte linear address space, and hardware 16×16→32-bit multiplier with MAC support. Its memory subsystem includes on-chip program ROM (96 KB), data flash with BGO, and SRAM (8 KB), enabling firmware updates without halting execution.
Peripheral integration centers on deterministic timing control: Timer RD delivers three-phase complementary PWM (6-pin output) with triangular/sawtooth modulation for motor drive, while Timer RC provides 4-channel capture/compare and standard PWM. The LIN module leverages UART0 and Timer RA for hardware protocol compliance per ISO 9141-2 and SAE J2602.

FAQ
What is the maximum operating frequency and supply voltage range for the R5F2136ACNFP#30?
The R5F2136ACNFP#30 operates at up to 20 MHz when supplied at 2.7–5.5 V, and supports reduced-frequency operation down to 5 MHz at 1.8 V minimum supply. Its R8C CPU core achieves a minimum instruction execution time of 50 ns under 20 MHz conditions, enabling responsive real-time control in appliance interfaces and motor sequencing applications.
Does the R5F2136ACNFP#30 support in-application programming of its data flash memory?
Yes, the R5F2136ACNFP#30 supports Background Operation (BGO) for data flash - allowing program execution to continue uninterrupted while erasing or writing to any of its four 1 KB data flash blocks. This capability is essential for implementing field-upgradable firmware features in the R5F2136ACNFP#30 without system downtime.
Which timer modules in the R5F2136ACNFP#30 support complementary PWM output for motor control?
Timer RD in the R5F2136ACNFP#30 supports complementary PWM output with three-phase waveform generation across six dedicated pins (TRDIOA0–TRDIOD1), including hardware dead-time insertion via sawtooth and triangular wave modulation modes. This makes the R5F2136ACNFP#30 suitable for driving BLDC and stepper motors in consumer and office equipment.
What is the function of the XCIN/XCOUT pins on the R5F2136ACNFP#30?
The XCIN/XCOUT pins on the R5F2136ACNFP#30 connect to a 32.768 kHz crystal to drive the low-speed on-chip oscillator, which feeds Timer RE for real-time clock (RTC) operation. This enables calendar-mode timekeeping (seconds, minutes, hours, days of week) independent of the main system clock - a key feature for energy-efficient standby operation in the R5F2136ACNFP#30.
Is the R5F2136ACNFP#30 pin-compatible with other members of the R8C/36C Group?
Yes, the R5F2136ACNFP#30 shares the same 64-pin LQFP package (PLQP0064KB-A) and identical pin assignment with all R8C/36C Group variants using the FP suffix, including R5F21364CNFP through R5F2136CCNFP. This allows direct PCB reuse across memory- and feature-scaled versions of the R5F2136ACNFP#30 within the same product family.
