Product details
Overview
R5F64189DFB#UB from Renesas Electronics is a 100-pin LQFP 32-bit CISC microcontroller in the R32C/118 Group, featuring a 64 MHz CPU core, 1 Mbyte flash + 8 Kbytes data flash, 63 Kbytes RAM, dual CAN 2.0B modules (ISO 11898-1 compliant), nine UART channels with I²C-bus capability, and 26-channel 10-bit A/D conversion - deployed in automotive audio and industrial control systems requiring deterministic real-time response.
For engineers reviewing the R5F64189DFB#UB datasheet, R5F64189DFB#UB pinout, R5F64189DFB#UB application, or R5F64189DFB#UB equivalent, this page delivers verified package mapping (PLQP0100KB-A), confirmed 100-pin LQFP pin functions, validated CAN/I²C/UART peripheral integration, and direct alternative part comparisons for migration or second-sourcing decisions.
Technical Context
The R5F64189DFB#UB implements the R32C/100 Series CPU core with IEEE-754 single-precision FPU, 32-bit × 32-bit multiplier, and multiply-accumulate unit - enabling high-efficiency signal processing in motor control and audio DSP tasks. Its memory architecture supports up to 4 Gbytes address space with external bus expansion (8/16-bit data width, wait-state insertion).
Real-time operation is reinforced by 261 interrupt vectors, seven priority levels, and dedicated peripherals including three-phase motor control timer (using TA1–TA4/B2), 16-bit input capture (16 channels), and 16-bit output compare (19 channels) - all synchronized via a four-circuit clock generator (main/sub/PLL/on-chip oscillator) with oscillation stop detection.

FAQ
What is the maximum operating frequency of the R5F64189DFB#UB?
The R5F64189DFB#UB operates at a maximum CPU frequency of 64 MHz, achieved via its on-chip PLL clock generator. This high-speed capability enables sub-16 ns minimum instruction execution time and supports demanding real-time tasks such as audio buffering and motor commutation control in the R5F64189DFB#UB.
Does the R5F64189DFB#UB support CAN FD or only classical CAN?
The R5F64189DFB#UB supports only Classical CAN (CAN 2.0B) compliant with ISO 11898-1, with two independent channels and 32 mailboxes each. It does not implement CAN FD features such as flexible data-rate or extended payload length - those capabilities are absent from the R5F64189DFB#UB's CAN module specification.
How many analog input channels does the R5F64189DFB#UB provide?
The R5F64189DFB#UB integrates a 10-bit A/D converter with 26 input channels, as confirmed for the 100-pin package variant in Table 1.4 and Figure 1.4 of the official datasheet. This count excludes auxiliary analog pins like ANEX0/ANEX1 and matches the R5F64189DFB#UB's pin assignment and electrical specifications.
Is the R5F64189DFB#UB pin-compatible with other R32C/118 Group devices?
Yes - the R5F64189DFB#UB shares identical pinout and electrical characteristics with all other 100-pin R32C/118 Group variants (e.g., R5F64185DFB#UB, R5F64188DFB#UB), including identical function mapping for all 100 pins per Tables 1.11–1.13. This allows direct substitution within the same package family without PCB modification.
What debug interface does the R5F64189DFB#UB support?
The R5F64189DFB#UB supports Renesas' on-chip debug interface (OCD) via dedicated debug pins, enabling full JTAG-based in-circuit debugging, real-time trace, and flash programming without external emulators. This capability is built into the R5F64189DFB#UB silicon and documented in Section 2.3 of the R01DS0065EJ0120 datasheet.
