Product details
Overview
R5F2136ACDFA#V0 from Renesas Electronics is a 16-bit R8C CPU core microcontroller with 96 KB program ROM, 8 KB data flash (4 × 1 KB blocks), and 8 KB RAM, operating at up to 20 MHz (VCC = 2.7–5.5 V). It integrates UART0/1/2, I²C, LIN, 12-channel 10-bit ADC, dual 8-bit DAC, six timer modules (RA–RG), and background operation (BGO) for in-application data flash reprogramming - used in motor control subsystems of home appliance mainboards.
For engineers reviewing the R5F2136ACDFA#V0 datasheet, R5F2136ACDFA#V0 pinout, R5F2136ACDFA#V0 application, or R5F2136ACDFA#V0 equivalent, key selection criteria include its −40°C to +85°C industrial temperature grade, 64-pin LQFP (PLQP0064GA-A) package, integrated LIN hardware module, BGO-enabled data flash, and real-time clock (Timer RE) with calendar mode.
Technical Context
The R5F2136ACDFA#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 (00000h–FFFFFh), with fixed interrupt vector table at 0FFDCh–0FFFFh and data flash at 03000h–03FFFh.
Peripheral integration includes Timer RD (16-bit ×2, 6-pin PWM, complementary & reset-synchronous modes), Timer RC (16-bit, 3-pin PWM), and UART2 supporting I²C bus mode - all accessible via programmable I/O ports with selectable pull-up resistors and high-current drive capability on all 59 CMOS I/O pins.

Does the R5F2136ACDFA#V0 support in-system programming of its data flash memory?
Yes, the R5F2136ACDFA#V0 supports background operation (BGO) for data flash, allowing program execution to continue uninterrupted during erase or write cycles. This capability is essential for implementing robust firmware update mechanisms and nonvolatile parameter storage in real-time control applications.
How many analog-to-digital converter channels does the R5F2136ACDFA#V0 include, and what is their resolution?
The R5F2136ACDFA#V0 integrates a 10-bit successive-approximation ADC with 12 input channels (AN0–AN11), including sample-and-hold and hardware sweep mode. All channels are multiplexed onto dedicated pins (P0_0–P0_7, P1_0–P1_3) and support configurable conversion triggers including internal timers and external pins.
Is the R5F2136ACDFA#V0 pin-compatible with other members of the R8C/36C Group?
Yes, all R8C/36C Group MCUs in the PLQP0064GA-A package - including R5F21364CDFA#V0 through R5F2136CCDFA#V0 - share identical 64-pin LQFP pinouts and I/O functionality. Firmware portability is further ensured by consistent peripheral register mapping and instruction set architecture across the group.
