Renesas R5F2136CCNFP#50

Overview

R5F2136CCNFP#50 from Renesas Electronics is a 16-bit R8C CPU core microcontroller with 128 KB program ROM, 10 KB data flash (4 × 1 KB blocks), and 10 KB RAM in a 64-pin LQFP (PLQP0064KB-A) package. It operates at up to 20 MHz (V_CC = 2.7–5.5 V), integrates 12-channel 10-bit ADC, dual 8-bit DACs, LIN hardware module, and six independent timers including complementary PWM-capable Timer RD for motor control. It targets embedded control in consumer audio and office equipment.

For engineers reviewing the R5F2136CCNFP#50 datasheet, R5F2136CCNFP#50 pinout, R5F2136CCNFP#50 application, or R5F2136CCNFP#50 equivalent, key selection criteria include its 128 KB flash capacity, background operation (BGO) support for data flash, −20°C to +85°C industrial temperature grade (N version), integrated LIN transceiver capability via UART0 + Timer RA, and 64-pin LQFP footprint with 59 CMOS I/O ports and high-current drive capability.

Technical Context

The R5F2136CCNFP#50 implements the R8C CPU core with 89 fundamental instructions, 1 Mbyte address space, and a dedicated 16×16→32-bit multiplier with MAC support. Its memory architecture separates program ROM (04000h–23FFFh), data flash (03000h–03FFFh), and RAM (00400h–02BFFh), enabling concurrent BGO writes to data flash while executing code from ROM.

Peripheral integration includes three UART/serial interfaces (UART0–UART2), I²C bus (shared with SSU), hardware LIN (using UART0 and Timer RA), 16-bit Timer RD with reset-synchronous and complementary PWM modes for 3-phase motor drive, and DTC for autonomous data transfers triggered by 39 sources - reducing CPU overhead in real-time control loops.

FAQ

What is the maximum operating frequency and supply voltage range for the R5F2136CCNFP#50?

The R5F2136CCNFP#50 operates at up to 20 MHz when supplied with 2.7–5.5 V, achieving a minimum instruction execution time of 50 ns. At lower voltages down to 1.8 V, it supports 5 MHz operation with 200 ns minimum instruction time - enabling flexible power/performance trade-offs in battery-powered or mixed-voltage systems. This dual-frequency capability is confirmed in Table 1.1 of the R01DS0018EJ0110 datasheet.

Does the R5F2136CCNFP#50 support background operation (BGO) for data flash programming?

Yes, the R5F2136CCNFP#50 supports background operation (BGO) for its 1 KB × 4 data flash blocks. This allows the CPU to execute code from program ROM while simultaneously erasing or programming data flash - essential for seamless firmware updates or real-time data logging. BGO functionality is explicitly documented in Section 1.1 and Table 1.2 of the R01DS0018EJ0110 datasheet.

How many analog-to-digital converter (ADC) channels does the R5F2136CCNFP#50 integrate, and what is their resolution?

The R5F2136CCNFP#50 integrates a single 10-bit successive-approximation ADC with 12 input channels (AN0–AN11), including sample-and-hold and hardware sweep mode. This configuration supports simultaneous sampling of multiple sensors without external multiplexing. The ADC specification is fully detailed in Table 1.2 under "A/D Converter" in the R01DS0018EJ0110 datasheet.

What peripheral functions enable LIN bus communication on the R5F2136CCNFP#50?

The R5F2136CCNFP#50 implements hardware LIN 2.0/2.1 communication using UART0 combined with Timer RA for baud rate generation and synchronization - eliminating the need for an external LIN transceiver in basic slave-node applications. This integrated LIN module is explicitly listed in Table 1.2 under "LIN Module" and verified in Section 1.1.1 of the R01DS0018EJ0110 datasheet.

What is the operating temperature range and package type of the R5F2136CCNFP#50?

The R5F2136CCNFP#50 is rated for −20°C to +85°C (N version) and housed in a 64-pin LQFP package with code PLQP0064KB-A (10 mm × 10 mm, 0.5 mm pitch). This package variant is confirmed in Table 1.3 of the R01DS0018EJ0110 datasheet and Figure 1.1, distinguishing it from the GA-A and FB variants.
