Product details
Overview
R5F2136CWKFP#U0 from Renesas is a 16-bit R8C CPU core microcontroller with 128 KB program flash, 10 KB RAM, and 4 KB data flash (1 KB × 4 blocks) supporting background operation (BGO). It integrates a single-channel CAN module compliant with ISO 11898-1 (16 mailboxes), 10-bit 16-channel ADC with sample-and-hold, and six timer units including three-phase PWM-capable Timer RD. It targets automotive LAN and industrial FA systems operating from −40°C to +125°C.
For engineers reviewing the R5F2136CWKFP#U0 datasheet, R5F2136CWKFP#U0 pinout, R5F2136CWKFP#U0 application, or R5F2136CWKFP#U0 equivalent, key selection criteria include CAN interface compliance, K-version extended temperature rating, BGO-enabled data flash reprogramming during runtime, and 64-pin LQFP package compatibility with existing R8C/36W Group layouts.
Technical Context
The R5F2136CWKFP#U0 implements the R8C CPU core with 89 fundamental instructions and a dedicated 16×16→32-bit hardware multiplier for deterministic real-time control. Its clock system includes XIN/XOUT crystal oscillator, high-speed on-chip oscillator (frequency-adjustable), and low-speed on-chip oscillator - all supporting oscillation stop detection and selectable frequency division (1/2/4/8/16).
Peripheral integration centers on deterministic timing and communication: Timer RD provides reset-synchronous and complementary PWM for motor control; UART2 supports I²C-bus and IEBus modes; LIN is implemented via hardware timers and UARTs; and the CAN module operates independently with dedicated mailbox buffers and message filtering logic.

Does the R5F2136CWKFP#U0 support in-system programming and debug interfaces?
Yes, the R5F2136CWKFP#U0 includes on-chip debug functionality and supports on-board flash rewrite operations. It enables full in-system programming via its built-in debug interface without requiring external programmers, and the background operation (BGO) function allows data flash updates while the main application runs - critical for field-upgradable features in R5F2136CWKFP#U0-based automotive and industrial systems.
How many CAN mailboxes does the R5F2136CWKFP#U0 provide, and what standard does it comply with?
The R5F2136CWKFP#U0 provides 16 dedicated CAN mailboxes and fully complies with ISO 11898-1 for high-speed CAN communication. This mailbox architecture supports efficient message filtering, prioritization, and transmission scheduling - essential for deterministic communication in R5F2136CWKFP#U0-based automotive networks such as body control or powertrain subsystems.
What is the purpose of the data flash in the R5F2136CWKFP#U0, and how is it structured?
The R5F2136CWKFP#U0 includes 4 KB of data flash organized as four 1 KB blocks, each individually erasable and programmable. It supports background operation (BGO), allowing read/write operations during normal program execution - making it ideal for storing calibration parameters, event logs, or configuration data in R5F2136CWKFP#U0 applications like automotive ECUs or industrial controllers requiring nonvolatile runtime updates.
Which timer peripherals in the R5F2136CWKFP#U0 support three-phase motor control waveforms?
Timer RD in the R5F2136CWKFP#U0 supports both reset-synchronous PWM and complementary PWM modes, generating precise three-phase waveforms across six output pins with configurable dead-time insertion and fault synchronization. This capability is directly leveraged in R5F2136CWKFP#U0-based motor drives for HVAC, pumps, and conveyors where deterministic timing and hardware-level safety coordination are mandatory.
