Product details
Overview
R5F21364CNFP#V0 from Renesas Electronics is a 16-bit R8C CPU core microcontroller with 16 KB program ROM, 1.5 KB data flash (4 × 1 KB blocks), and 1.5 KB RAM in a 64-pin LQFP (PLQP0064KB-A) package. It operates at up to 20 MHz (VCC = 2.7–5.5 V), integrates 12-channel 10-bit ADC, dual 8-bit DACs, LIN hardware module, and supports real-time clock, PWM, and background flash programming - deployed in consumer audio and office equipment control systems.
For engineers reviewing the R5F21364CNFP#V0 datasheet, R5F21364CNFP#V0 pinout, R5F21364CNFP#V0 application, or R5F21364CNFP#V0 equivalent, key selection considerations include its N-version temperature range (−20°C to +85°C), 64-pin LQFP footprint, integrated LIN transceiver support via UART0+TimerRA, and BGO-enabled data flash for firmware updates without halting execution.
Technical Context
The R5F21364CNFP#V0 implements the R8C CPU core with 89 fundamental instructions, 16×16→32-bit multiplier, and multiply-accumulate capability. Its memory map spans 1 Mbyte address space, with fixed interrupt vector table at 0FFDCh–0FFFFh and data flash mapped to 03000h–03FFFh.
It features four independent clock sources: XIN (up to 20 MHz crystal/resonator), XCIN (32 kHz crystal), high-speed on-chip oscillator (adjustable), and low-speed on-chip oscillator - enabling flexible power mode management including wait (4.0 µA @ 3.0 V, 32 kHz) and stop (2.0 µA) modes.

FAQ
What is the operating temperature range for R5F21364CNFP#V0?
The R5F21364CNFP#V0 is an N-version device rated for −20°C to +85°C ambient operating temperature. This specification is confirmed in Table 1.2 of the R01DS0018EJ0110 datasheet and applies to all variants with "N" in the part number suffix. Industrial applications requiring −40°C operation should select the D-version counterpart R5F21364CDFP.
Does R5F21364CNFP#V0 support in-circuit debugging?
Yes, R5F21364CNFP#V0 includes on-chip debug functionality per the R8C/36C Group datasheet. It supports full-breakpoint, single-step, and memory/register inspection via the standard Renesas E8/E8a debug interface. Debug access requires no external hardware beyond a compatible debugger and adheres to the R8C CPU's dedicated debug register set.
How many I/O pins does R5F21364CNFP#V0 have, and what are their drive capabilities?
R5F21364CNFP#V0 provides 59 CMOS I/O ports (P0–P8, excluding input-only P4_2) with software-selectable pull-up resistors. All 59 pins support high-current drive mode per datasheet Table 1.1, enabling direct LED driving or relay coil control without external buffers - critical for reducing component count in appliance control boards.
Can R5F21364CNFP#V0 execute code while programming data flash?
Yes, R5F21364CNFP#V0 supports Background Operation (BGO) for data flash, allowing CPU code execution to continue uninterrupted during erase and write operations on its 4 × 1 KB data flash blocks. This capability is explicitly documented in Section 1.1 and Table 1.2 of the datasheet and is essential for fail-safe firmware updates in always-on devices.
What clock sources are available on R5F21364CNFP#V0?
R5F21364CNFP#V0 integrates four clock sources: XIN/XOUT (up to 20 MHz crystal/resonator), XCIN/XCOUT (32.768 kHz crystal for RTC), high-speed on-chip oscillator (adjustable frequency), and low-speed on-chip oscillator. These enable dynamic clock switching between performance and ultra-low-power modes - e.g., 20 MHz for active processing and 32 kHz for Timer RE real-time clock in stop mode.
