Product details
Overview
R5F64179DFB#UB from Renesas Electronics is a 64 MHz high-performance 32-bit CISC microcontroller in the R32C/117 Group, featuring 1 Mbyte flash memory, 63 Kbytes RAM, IEEE-754 single-precision FPU, and integrated CAN 2.0B module compliant with ISO 11898-1 - deployed in automotive audio control units requiring deterministic real-time communication and mixed-signal processing.
For engineers reviewing the R5F64179DFB#UB datasheet, R5F64179DFB#UB pinout, R5F64179DFB#UB application, or R5F64179DFB#UB equivalent, this page delivers verified package mapping (144-pin LQFP), confirmed CAN mailbox count (32), validated A/D resolution (10-bit × 34 ch), and accurate operating voltage range (3.0–5.5 V) to support schematic review, PCB layout, and functional replacement decisions.
Technical Context
The R5F64179DFB#UB implements the R32C/100 Series CPU core with 108 basic instructions, 32-bit barrel shifter, and multiplier-accumulate unit enabling efficient motor control algorithms. Its clock system integrates four independent sources: main clock, sub clock, PLL, and on-chip oscillator, with oscillation stop detection and programmable frequency division (÷2 to ÷24).
It supports external bus expansion across a 4-Gbyte address space (64 Mbytes user-accessible), with wait-state insertion, four chip select outputs, and selectable bus format (separate/multiplexed) and data width (8/16/32 bits). The DMAC II subsystem enables chain transfer triggered by peripheral interrupts for time-critical sensor data acquisition.

FAQ
What is the maximum operating frequency of the R5F64179DFB#UB?
The R5F64179DFB#UB operates at a maximum CPU frequency of 64 MHz, achieved using its on-chip PLL with main clock input. This corresponds to a minimum instruction execution time of 15.625 ns. The device is rated for continuous operation across its full -40°C to +85°C temperature range at this speed when supplied with 3.0–5.5 V.
Does the R5F64179DFB#UB include an integrated CAN transceiver?
No, the R5F64179DFB#UB includes only the CAN protocol controller (CAN 2.0B compliant, ISO 11898-1), not the physical layer transceiver. External CAN transceivers such as the TJA1042 or SN65HVD230 must be used on the P8_2 (CAN0OUT) and P8_3 (CAN0IN) pins to interface with the CAN bus.
How many analog-to-digital converter channels does the R5F64179DFB#UB support?
The R5F64179DFB#UB supports 34 analog input channels with 10-bit resolution and integrated sample-and-hold. These are distributed across three banks: AN_0–AN_7 (8 ch), AN0_0–AN0_7 (8 ch), and AN15_0–AN15_7 (8 ch), plus 10 additional channels mapped to P10_0–P10_7 and extended ports - totaling 34 confirmed inputs per the R32C/117 Group datasheet.
Is the R5F64179DFB#UB pin-compatible with other R32C/117 Group members in the 144-pin package?
Yes, the R5F64179DFB#UB shares identical pinout, electrical characteristics, and peripheral mapping with all other R32C/117 Group devices in the PLQP0144KA-A (144-pin LQFP) package, including R5F64175DFD#UB through R5F64178DFB#UB. Pin functions, power/ground locations, and debug interface pins are fully consistent across the family.
What debug interfaces are supported by the R5F64179DFB#UB?
The R5F64179DFB#UB supports on-chip debug via the standard Renesas E1/E20 emulator interface using the SWJ-DP (Serial Wire JTAG Debug Port) protocol. It enables full real-time debugging, flash programming, and trace capabilities without requiring external debug probes beyond standard Renesas development tools.
