Product details
Overview
R5F2136CCDFA#X4 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 (PLQP0064GA-A) package. It delivers 50 ns minimum instruction execution at 20 MHz (VCC = 2.7–5.5 V), integrates 12-channel 10-bit ADC, dual 8-bit DACs, LIN hardware module, and supports real-time clock, PWM, and background flash programming - deployed in industrial motor control and appliance power management systems.
For engineers reviewing the R5F2136CCDFA#X4 datasheet, R5F2136CCDFA#X4 pinout, R5F2136CCDFA#X4 application, or R5F2136CCDFA#X4 equivalent, key selection criteria include its −40°C to +85°C extended temperature rating (D version), 64-pin LQFP package with 59 CMOS I/O ports, integrated LIN transceiver support via Timer RA and UART0, and BGO-enabled data flash for firmware updates without halting operation.
Technical Context
The R5F2136CCDFA#X4 implements the R8C CPU core with 89 fundamental instructions, 1 Mbyte address space, and a dedicated 16×16→32-bit multiplier with MAC capability. Its memory architecture separates 128 KB program ROM (flash), 10 KB data flash (BGO-capable), and 10 KB RAM across non-overlapping address regions (04000h–23FFFh for ROM, 03000h–03FFFh for data flash, 00400h–02BFFh for RAM).
Peripheral integration includes four independent timer units (RA–RD, RE–RG) supporting input capture, output compare, PWM (up to 6 pins in complementary mode), and three UART/I²C/SSU serial interfaces with LIN protocol acceleration. Clock generation combines XIN (20 MHz max), XCIN (32 kHz), high-speed on-chip oscillator (adjustable), and low-speed on-chip oscillator with oscillation stop detection.

FAQ
What is the maximum operating frequency and corresponding supply voltage requirement for the R5F2136CCDFA#X4?
The R5F2136CCDFA#X4 achieves a maximum operating frequency of 20 MHz when supplied with VCC = 2.7–5.5 V. At lower voltages (1.8–5.5 V), the device operates up to 5 MHz. This dual-voltage/frequency specification allows flexible power rail selection - supporting both battery-powered portable devices and fixed 3.3 V/5 V industrial systems without performance compromise.
Does the R5F2136CCDFA#X4 support background operation (BGO) for data flash programming?
Yes, the R5F2136CCDFA#X4 supports Background Operation (BGO) for its 10 KB data flash (organized as four 1 KB blocks). This enables concurrent CPU code execution and flash erase/write operations - critical for over-the-air firmware updates in deployed systems where uninterrupted real-time control is mandatory. BGO is controlled via dedicated SFR bits and requires no external hardware intervention.
How many I/O pins does the R5F2136CCDFA#X4 provide, and what are their electrical characteristics?
The R5F2136CCDFA#X4 provides 59 CMOS I/O ports with programmable pull-up resistors, plus one dedicated input-only pin (P4_2/VREF). All I/Os are 5 V tolerant when VCC ≤ 5.5 V and support high-current drive capability. Pin functions are fully configurable via port direction registers, allowing dynamic reassignment of peripherals such as UART, timers, and ADC channels without hardware changes.
What LIN protocol versions are supported by the hardware LIN module in the R5F2136CCDFA#X4?
The R5F2136CCDFA#X4 hardware LIN module implements ISO 9141-2 and LIN 2.x physical and data link layers using Timer RA and UART0. It supports standard LIN frame structures, checksum modes (classic/enhanced), and automatic sync-break detection - compliant with LIN Consortium specifications up to LIN 2.2A. No external transceiver is required beyond standard LIN bus termination.
What is the purpose and configuration method for the XCIN/XCOUT pins on the R5F2136CCDFA#X4?
The XCIN/XCOUT pins on the R5F2136CCDFA#X4 connect to a 32.768 kHz crystal to drive the low-speed on-chip oscillator, which feeds Timer RE for real-time clock (RTC) functionality. Configuration is automatic upon power-up; the RTC operates independently in wait/stop modes. No software initialization is needed beyond enabling Timer RE - ensuring calendar timekeeping (seconds/minutes/hours/days) persists during ultra-low-power states.
