Product details
Overview
R5F21336CYFP#V2 from Renesas Electronics is a 16-bit R8C CPU core microcontroller in the R8C/36C Group, designed for embedded control in cost-sensitive consumer and industrial applications. It features 32 KB program ROM, 2.5 KB data flash (4 × 1 KB blocks with background operation), 10-bit A/D converter (12 channels), dual 8-bit D/A converters, and integrated LIN hardware module. It operates at up to 20 MHz (VCC = 2.7–5.5 V) and supports −40°C to +85°C ambient temperature (D version).
For engineers reviewing the R5F21336CYFP#V2 datasheet, R5F21336CYFP#V2 pinout, R5F21336CYFP#V2 application, or R5F21336CYFP#V2 equivalent, key selection criteria include its 64-pin LQFP package (PLQP0064KB-A), real-time clock (Timer RE), low-power stop mode (2.0 µA), and hardware LIN support via Timer RA and UART0 - critical for automotive body electronics and appliance motor control.
Technical Context
The R5F21336CYFP#V2 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 at 03000h–03FFFh.
Peripheral integration includes four independent timer units (RA–RD), Timer RE for real-time clock functions, UART0/1/2 with I²C and LIN modes, and a Data Transfer Controller (DTC) supporting 39 activation sources. Clock generation combines XIN/XOUT (up to 20 MHz), XCIN/XCOUT (32 kHz), and two on-chip oscillators (high-speed with frequency adjustment, low-speed).

FAQ
What is the operating temperature range for R5F21336CYFP#V2?
The R5F21336CYFP#V2 is a D-version device rated for −40°C to +85°C operating ambient temperature, validated per Renesas specification R01DS0018EJ0110. This rating applies across all specified supply voltages (1.8–5.5 V) and functional modes including stop mode and real-time clock operation with XCIN oscillator.
Does R5F21336CYFP#V2 support background operation for data flash writes?
Yes, R5F21336CYFP#V2 supports Background Operation (BGO) for its 1 KB × 4 data flash blocks. This allows concurrent CPU program execution and flash erase/write operations - essential for in-field firmware updates without interrupting real-time control loops or RTC functions.
Which pins on R5F21336CYFP#V2 are used for the hardware LIN interface?
The hardware LIN interface on R5F21336CYFP#V2 uses UART0 (pins P1_4/TXD0 and P1_5/RXD0) combined with Timer RA (TRAIO on P3_2) for baud rate generation and synchronization. This configuration implements LIN 2.1 physical layer compliance without external transceiver timing components.
What is the minimum instruction execution time for R5F21336CYFP#V2 at 20 MHz?
At f(XIN) = 20 MHz and VCC = 2.7–5.5 V, the R5F21336CYFP#V2 achieves a minimum instruction execution time of 50 ns. This timing is guaranteed across the full D-version temperature range and enables deterministic loop execution for motor control and real-time signal processing.
How many capture/compare registers does Timer RC support on R5F21336CYFP#V2?
Timer RC on R5F21336CYFP#V2 supports 4 capture/compare registers, enabling simultaneous input capture on multiple edges and independent PWM output on up to 3 pins. This capability is directly confirmed in Table 1.1 of the R01DS0018EJ0110 datasheet for the R8C/36C Group.
