Renesas R5F2136CCDFA#50

Overview

R5F2136CCDFA#50 from Renesas 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 (PLQP0064GA-A) package. It delivers 50 ns minimum instruction execution at 20 MHz (V_CC = 2.7–5.5 V), integrates dual 10-bit A/D converters (12 channels), dual 8-bit D/A outputs, LIN hardware module, and supports −40°C to +85°C operation for industrial motor control and appliance timing systems.

For engineers reviewing the R5F2136CCDFA#50 datasheet, R5F2136CCDFA#50 pinout, R5F2136CCDFA#50 application, or R5F2136CCDFA#50 equivalent, key selection criteria include its background operation (BGO) data flash capability, real-time clock (Timer RE), complementary PWM modes on Timer RD, and hardware LIN support - all critical for deterministic embedded control in cost-sensitive industrial and consumer applications.

Technical Context

The R5F2136CCDFA#50 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.

Peripheral integration includes Timer RD (16-bit × 2, 6-pin complementary PWM), UART0/1/2 with I²C mode, SSU shared with I²C bus, and a dedicated hardware LIN module using Timer RA and UART0 - enabling single-chip implementation of LIN slave nodes without external transceivers.

FAQ

What is the operating temperature range of the R5F2136CCDFA#50?

The R5F2136CCDFA#50 is a D-version device rated for −40°C to +85°C ambient operation, making it suitable for industrial environments where extended thermal stability is required. This specification is confirmed in Table 1.2 of the R01DS0018EJ0110 datasheet and distinguishes it from N-version variants like R5F2136CCNFA.

Does the R5F2136CCDFA#50 support background operation (BGO) for data flash?

Yes, the R5F2136CCDFA#50 supports background operation (BGO) for its 4 × 1 KB data flash blocks, allowing program/erase operations to execute concurrently with CPU code execution. This capability is explicitly documented in Section 1.1 and Table 1.2 of the R01DS0018EJ0110 datasheet and enables safe in-field firmware updates without system interruption.

How many A/D converter channels does the R5F2136CCDFA#50 provide, and what is their resolution?

The R5F2136CCDFA#50 integrates a 10-bit A/D converter with 12 input channels (AN0–AN11), including sample-and-hold and sweep mode functionality. This is specified in Table 1.2 under "A/D Converter" and enables simultaneous multi-sensor acquisition in applications such as motor current sensing and environmental monitoring.

Is hardware LIN support built into the R5F2136CCDFA#50?

Yes, the R5F2136CCDFA#50 includes a dedicated hardware LIN module compliant with LIN 2.0/2.1, implemented using Timer RA and UART0. This eliminates the need for external LIN transceivers in slave-node designs and is confirmed in Table 1.2 and Figure 1.2 of the R01DS0018EJ0110 datasheet.

What package type is used for the R5F2136CCDFA#50?

The R5F2136CCDFA#50 uses the PLQP0064GA-A package: a 64-pin LQFP with 10 mm × 10 mm body and 0.5 mm pitch. This is verified in Table 1.4 (Product List) and Figure 1.1 of the R01DS0018EJ0110 datasheet, and matches the "FA" suffix in the part number.
