R5F64176PFB
R5F64176PFB - 50MHz 32-Bit 512KB Flash MCU | Renesas
The Renesas Electronics R5F64176PFB is a 32-bit M32C/R32C-series microcontroller operating at 50 MHz with 512 KB of flash memory in a 100-LFQFP package. The verified distributor listing identifies the device as an R32C/100/117 MCU with 16/32-bit capability and a 14 x 14 mm package. These core values position it for embedded systems that require substantial nonvolatile program storage and a relatively high CPU clock.
A microcontroller is a programmable semiconductor that integrates a CPU core, memory, peripheral interfaces, and control logic on one device. The M32C family belongs to the embedded-microcontroller hierarchy: microcontroller -> embedded processor -> semiconductor. Renesas R32C devices are designed for embedded control, communications, industrial equipment, and consumer electronics where firmware must coordinate sensors, actuators, data links, and local user interfaces.
The verified data confirms 50 MHz operation, 512 KB organized as 512K x 8 flash, a 32-bit architecture, and a 100-LFQFP package. It does not provide verified values for RAM, GPIO count, timer resources, communication peripherals, supply range, operating temperature, or package pin assignments. Those specifications must be obtained from the official R5F64176PFB datasheet before schematic capture, firmware porting, or PCB release.
The 512 KB flash allocation can hold substantially more application code and constants than many compact 8-bit microcontrollers, while the 50 MHz rating supports more responsive control loops and protocol handling than lower-frequency devices. Actual application performance still depends on bus timing, flash wait states, peripheral configuration, interrupt structure, and firmware efficiency. The 100-lead package also requires careful escape routing because its lead count exceeds common 32-pin and 64-pin microcontroller packages.
Typical design uses include industrial controllers, building automation equipment, sensor-hub platforms, motor-control supervisory logic, serial-protocol gateways, and human-interface modules. A 32-bit RISC-style embedded control task benefits from the available processing headroom, but application-specific peripheral and timing requirements must be verified. XAIPART’s distributor search identifies availability and purchasing channels, but the listing alone does not establish a fixed unit price or guaranteed stock quantity.
Place decoupling capacitors beside the appropriate supply pins, preserve the manufacturer’s recommended clock and reset implementation, and assign unused pins according to the official datasheet. Do not infer a substitute solely from package similarity: software compatibility, memory organization, interrupt mapping, peripheral mix, and electrical limits must match before a replacement is approved. For programmed production units, verify trace, programming, marking, and lot traceability with purchasing and manufacturing teams.
This product record consolidates verified distributor specifications, sourcing links, package details, and engineering-selection guidance. It distinguishes confirmed facts from missing data so engineers can identify what requires confirmation from the manufacturer datasheet before committing the MCU to a new embedded platform.
