Product details
Overview
R5F21364CNFP#10 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), features a 16×16→32-bit hardware multiplier, 12-channel 10-bit ADC, dual 8-bit DACs, LIN hardware module, and supports real-time clock, PWM, and background data flash programming - deployed in consumer audio equipment and office automation control systems.
For engineers reviewing the R5F21364CNFP#10 datasheet, R5F21364CNFP#10 pinout, R5F21364CNFP#10 application, or R5F21364CNFP#10 equivalent, key selection criteria include its N-version industrial temperature range (−20°C to +85°C), integrated LIN transceiver support via UART0+TimerRA, BGO-enabled data flash for firmware updates without halting execution, and low-power stop mode consuming only 2.0 µA at 3.0 V.
Technical Context
The R5F21364CNFP#10 implements the R8C CPU core with 89 fundamental instructions and 20-bit addressing (1 Mbyte space), executing instructions in as little as 50 ns at 20 MHz. Its memory architecture separates program ROM (04000h–0C000h), data flash (03000h–03FFFh), and RAM (00400h–009FFh), enabling concurrent code execution and background flash reprogramming.
Peripheral integration includes Timer RD (16-bit ×2, 6-pin complementary PWM), UART0/1/2 with I²C and LIN modes, SSU shared with I²C bus, and two independent comparator B circuits - all mapped to fully configurable CMOS I/O ports (59 pins, pull-up selectable) with dedicated analog inputs (AN0–AN11) and D/A outputs (DA0, DA1).

FAQ
What is the maximum operating frequency and supply voltage range for the R5F21364CNFP#10?
The R5F21364CNFP#10 operates at up to 20 MHz when supplied with 2.7–5.5 V. At reduced voltage (1.8–5.5 V), it supports 5 MHz operation for ultra-low-power applications. Its 50 ns minimum instruction execution time at 20 MHz enables responsive real-time control in audio and motor applications - a key performance metric confirmed in Table 1.1 of the R01DS0018EJ0110 datasheet.
Does the R5F21364CNFP#10 support hardware LIN communication, and how is it implemented?
Yes, the R5F21364CNFP#10 integrates hardware LIN 2.1 functionality using UART0 combined with TimerRA for baud rate generation and sync field detection. This eliminates external transceiver components in body-control modules. The implementation is documented in Section 1.1.2 and Figure 1.2 of the R01DS0018EJ0110 datasheet, confirming full protocol stack offload without CPU intervention.
What are the data flash endurance and programming voltage requirements for the R5F21364CNFP#10?
The R5F21364CNFP#10 provides 1 KB × 4 blocks of data flash rated for 10,000 write/erase cycles, programmable and erasable at VCC = 2.7–5.5 V. Background Operation (BGO) allows concurrent code execution during flash writes - essential for firmware updates in running systems. These specifications are explicitly stated in Table 1.2 and Section 1.1 of the R01DS0018EJ0110 datasheet.
How many analog input channels and what ADC resolution does the R5F21364CNFP#10 provide?
The R5F21364CNFP#10 includes a 10-bit successive-approximation ADC with 12 dedicated analog input channels (AN0–AN11), supporting sample-and-hold and automatic sweep mode. This enables simultaneous multi-sensor acquisition in applications like HVAC control or audio input level detection - verified in Table 1.2 and Figure 1.2 of the R01DS0018EJ0110 datasheet.
What low-power modes are available on the R5F21364CNFP#10, and what are their typical current draws?
The R5F21364CNFP#10 supports wait mode (4.0 µA @ 3.0 V, 32 kHz XCIN) and stop mode (2.0 µA @ 3.0 V), both retaining RAM content and enabling wake-up via interrupts or external reset. These values are measured per Table 1.2 and validated in Section 1.1.2 of the R01DS0018EJ0110 datasheet - making it suitable for battery-powered remote controls and sensor nodes.
