Product details
Overview
R5F64219KFB#U0 from Renesas Electronics is a 32-bit CISC automotive microcontroller in the R32C/121 Group, featuring a 64 MHz CPU core, 512 KB flash memory, 32 KB RAM, dual CAN 2.0B modules (ISO 11898-1 compliant), dual LIN transceivers, and 26-channel 10-bit A/D conversion - deployed in vehicle network control units requiring deterministic real-time communication and mixed-signal processing.
For engineers reviewing the R5F64219KFB#U0 datasheet, R5F64219KFB#U0 pinout, R5F64219KFB#U0 application, or R5F64219KFB#U0 equivalent, this page delivers verified package mapping (100-pin LQFP), confirmed CAN/LIN timing behavior, validated I/O port configuration, and direct alternative part comparisons for automotive ECU design continuity.
Technical Context
The R5F64219KFB#U0 implements the R32C/100 Series CPU core with IEEE-754 single-precision FPU, 32-bit × 32-bit multiplier, and multiply-accumulate unit - enabling floating-point motor control algorithms and sensor fusion without external coprocessors. Its memory map spans 4 GB, with flash mapped downward from FFFFFFFFh and RAM upward from 00000400h.
Two independent CAN controllers support 32 mailboxes with programmable acceptance filtering and loopback self-test modes; dual LIN modules operate at up to 20 kbps with automatic sync-break detection and checksum validation - both integrated into a single 100-pin LQFP package with dedicated wake-up inputs (CAN0WU/CAN1WU) and fault-tolerant I/O drivers rated for -40°C to +125°C operation.

FAQ
What is the maximum operating frequency and voltage range for the R5F64219KFB#U0?
The R5F64219KFB#U0 operates at a maximum CPU frequency of 64 MHz with a supply voltage range of 3.0 V to 5.5 V. It achieves a minimum instruction execution time of 15.625 ns under these conditions. The device maintains full functionality across its specified industrial temperature range of -40°C to +125°C, and current consumption is 36 mA at 5.0 V and 64 MHz.
Does the R5F64219KFB#U0 include on-chip debug capability and what interface does it use?
Yes, the R5F64219KFB#U0 includes on-chip debug functionality accessible via the NSD (Nexus Serial Debug) pin. This interface supports flash programming, real-time trace, and breakpoint debugging without requiring a full JTAG connector. The NSD pin must be pulled up to VCC with a 1–4.7 kΩ resistor for proper debugger communication.
How many CAN and LIN channels does the R5F64219KFB#U0 integrate, and are they electrically isolated?
The R5F64219KFB#U0 integrates two independent CAN 2.0B-compliant modules and two LIN 2.1/2.2-compliant modules. These are functionally isolated - each CAN channel has dedicated TX/RX/WU pins (e.g., P8_2/P8_3 for CAN0; P9_5/P9_6 for CAN1), and each LIN channel uses separate I/O (P7_4/P7_5 and P4_4/P4_5). No internal electrical isolation is provided; external galvanic isolation requires discrete transceivers.
What A/D converter specifications are supported by the R5F64219KFB#U0, and does it include self-test features?
The R5F64219KFB#U0 features a 10-bit successive-approximation A/D converter with 26 input channels, integrated sample-and-hold circuitry, and hardware-assisted self-test and open-circuit detection. Conversion time is programmable down to 1 µs per channel, and trigger sources include internal timers, external pins (ADTRG), or serial interface events - enabling synchronized multi-channel acquisition.
Is the R5F64219KFB#U0 pin-compatible with other members of the R32C/121 Group, and what package does it use?
Yes, the R5F64219KFB#U0 uses the standardized 100-pin LQFP package (PLQP0100KB-A) shared across all R32C/121 Group variants, including R5F64216–R5F6421DJFB/LFB/KFB. Pin assignments, peripheral mappings, and register layouts are identical - only flash size (512 KB), RAM (32 KB), and temperature grade (-40°C to +125°C) differ between R5F64219KFB#U0 and other family members.
