For engineers reviewing the R5F64176DFB#2B datasheet, R5F64176DFB#2B pinout, R5F64176DFB#2B application, or R5F64176DFB#2B equivalent, this page delivers verified package mapping (PLQP0100KB-A), confirmed 50 MHz operation at 3.0–5.5 V, validated CAN mailbox count (32), exact A/D converter specification (10-bit × 26 channels), and alternative selection guidance for legacy R32C migration paths.
Technical Context
The R5F64176DFB#2B implements a 32-bit CISC architecture with multiplier, MAC unit, and barrel shifter, enabling high code efficiency in embedded control. 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).
Peripheral integration includes DMAC (4 channels, 51 request sources), intelligent I/O (16-bit input capture × 16, output compare × 19), and three-phase motor control timer (using TA1–TA4 and TB2). The device supports external bus expansion with 4 Gbyte address space, wait-state insertion, and 4 chip select outputs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F64176NFB#2B | Same 512 KB flash, 40 KB RAM, 100-pin LQFP, but rated for -20°C to +85°C (N version) | Not qualified for extended industrial temperature range (-40°C) | Select R5F64176NFB#2B only for commercial-grade environments where ambient temperature remains above -20°C |
| R5F64176DFD#2B | Identical electrical specs and peripherals, but packaged in 144-pin LQFP (PLQP0144KA-A) | Provides 34 A/D inputs (vs. 26), 24 intelligent I/O outputs (vs. 19), and additional ports P11–P15 | Choose R5F64176DFD#2B when higher I/O count, expanded analog channel density, or external memory interface bandwidth is required |
Compared with R5F64176NFB#2B, the R5F64176DFB#2B offers extended temperature qualification critical for industrial deployment; versus R5F64176DFD#2B, it trades pin count and peripheral density for compact 100-pin layout and lower PCB cost - ideal for space-constrained, thermally demanding applications.

FAQ
What is the maximum operating frequency of the R5F64176DFB#2B?
The R5F64176DFB#2B is a normal speed version microcontroller with a maximum operating frequency of 50 MHz at VCC = 3.0–5.5 V. It does not support the 64 MHz high-speed mode - that capability is reserved for part numbers suffixed with 'H' (e.g., R5F64176HDFB#2B). This 50 MHz rating ensures stable operation under extended temperature conditions (-40°C to +85°C).
Does the R5F64176DFB#2B include a CAN controller, and what standard does it support?
Yes, the R5F64176DFB#2B integrates one CAN module compliant with ISO 11898-1, supporting up to 32 independent mailboxes for message transmission and reception. It provides full CAN protocol handling including error framing, arbitration, and bit stuffing - enabling direct connection to automotive and industrial CAN networks without external transceivers (though an external CAN transceiver is still required for physical layer signaling).
How many analog-to-digital converter channels does the R5F64176DFB#2B support?
The R5F64176DFB#2B supports 26 channels of 10-bit A/D conversion, comprising eight dedicated AN_0–AN_7 pins (P10_0–P10_7) and eighteen additional AN0_0–AN0_7 plus AN2_0–AN2_7 inputs mapped across ports P0, P2, and P10. All channels feature integrated sample-and-hold functionality for accurate signal acquisition.
What is the flash and RAM capacity of the R5F64176DFB#2B?
The R5F64176DFB#2B contains 512 KB of main flash memory and two 4 KB data flash blocks (total 8 KB), along with 40 KB of on-chip RAM. Flash endurance is rated at ≥1,000 program/erase cycles, and both ROM code protection and ID code protection are implemented to secure firmware assets.
Is the R5F64176DFB#2B pin-compatible with other R32C/117 Group devices?
Yes, the R5F64176DFB#2B shares identical pinout and peripheral mapping with all other 100-pin R32C/117 Group variants (e.g., R5F64175DFB#2B, R5F64177DFB#2B), enabling drop-in replacement within the same package footprint. Pin compatibility extends across memory size, temperature grade, and speed variants - provided the target device uses the PLQP0100KB-A package.
