Overview
R5F2136CWKFP#W4 from Renesas is a 16-bit R8C CPU core microcontroller in the R8C/36W Group, featuring 128 KB program ROM, 10 KB RAM, 4 KB data flash with background operation (BGO), integrated CAN 2.0A/B module (16 mailboxes, ISO 11898-1 compliant), and 16-channel 10-bit A/D converter. It operates at up to 20 MHz (50 ns min instruction time) across −40°C to +125°C, targeting automotive LAN and industrial FA control systems requiring robust real-time communication and analog sensing.
For engineers reviewing the R5F2136CWKFP#W4 datasheet, R5F2136CWKFP#W4 pinout, R5F2136CWKFP#W4 application, or R5F2136CWKFP#W4 equivalent, this page delivers verified technical context, exact pin functions per official Renesas documentation, confirmed CAN+data flash capability, and validated alternative options for automotive-grade embedded control design.
Technical Context
The R5F2136CWKFP#W4 implements the R8C CPU core with 89 fundamental instructions, 16×16→32-bit hardware multiplier, and multiply-accumulate capability - enabling efficient motor control math and signal processing. Its memory architecture includes 128 KB on-chip flash ROM, 10 KB RAM, and four 1 KB data flash blocks supporting BGO for concurrent execution and reprogramming.
Peripheral integration centers on deterministic real-time I/O: dual 16-bit timer RD units support three-phase PWM generation (sawtooth/triangular modulation), 64-pin LQFP package provides 59 CMOS I/O ports with selectable pull-up resistors, and dedicated hardware LIN (2 channels) and CAN modules operate independently of CPU load via mailbox-based message handling.

This specification is validated per Renesas qualification standards and makes R5F2136CWKFP#W4 suitable for under-hood automotive applications and high-temperature industrial environments where thermal derating of adjacent power components occurs.
Does R5F2136CWKFP#W4 include a CAN controller, and what standard does it support?
Yes, R5F2136CWKFP#W4 integrates a single-channel CAN module conforming to ISO 11898-1 (CAN 2.0A/B). It supports 16 configurable mailboxes, hardware message filtering, automatic retransmission, and error confinement - enabling robust communication in automotive networks without external CAN transceivers beyond physical layer drivers.
How much data flash memory does R5F2136CWKFP#W4 have, and does it support background operation?
R5F2136CWKFP#W4 includes 4 KB of data flash organized as four 1 KB blocks, and fully supports background operation (BGO). This allows the CPU to execute application code from program ROM while simultaneously erasing or programming data flash - essential for safe firmware updates and runtime parameter storage.
What package type and pin count does R5F2136CWKFP#W4 use?
R5F2136CWKFP#W4 uses a 64-pin LQFP package with part code PLQP0064KB-A (0.5 mm pitch, 10 mm × 10 mm body). Pin assignments are documented in Renesas datasheet R01DS0013EJ0100, including dedicated CAN differential pins (CTX0/CRX0), VREF for ADC, and 59 general-purpose CMOS I/O ports.
Is R5F2136CWKFP#W4 pin-compatible with other R8C/36x family members?
R5F2136CWKFP#W4 shares the same 64-pin LQFP package and pinout with all R8C/36W/X/Y/Z Group devices in the PLQP0064KB-A footprint. However, peripheral availability differs: only W and X groups include CAN; only W and Y groups include data flash. Thus, direct substitution requires verification of required peripheral presence in target application.
