R5F10PMEKFB#X5 is listed in the Microcontrollers range at ChipApex. The manufacturer field lists Renesas Electronics Corporation. Its product description is IC MCU 16BIT LFQFP. Review the specifications below when checking this part for your BOM.
The R5F10PMEKFB#X5 is a 16-bit microcontroller from the Renesas RL78/F14 series, designed for automotive applications. It features a 64KB flash program memory and 6KB of RAM with ECC support. The device includes 4KB of data flash and operates at speeds up to 32MHz. It supports a supply voltage range of 1.6V to 5.5V and functions within an operating temperature range of -40°C to 85°C. The component is housed in a 64-pin LQFP package.
Verify the specific ordering suffix and package variant against the official Renesas datasheet before procurement. Confirm that the 64-pin LQFP form factor matches the target PCB design. Ensure compatibility with the required firmware architecture for the RL78 core. Check current production status as automotive components may have long lead times or obsolescence notices.
Select this component when ECC protection is critical for system reliability. The 64KB flash capacity suits moderate code complexity. Consider the 16-bit RL78 architecture for efficient integer processing. Verify that the 44-64 pin count aligns with I/O requirements. Evaluate power consumption profiles against the 1.6V to 5.5V supply constraints.
This part belongs to the RL78/F14 family, which extends the capabilities of previous RL78 generations. It targets cost-sensitive automotive applications requiring robust performance. The F14 series integrates standard peripherals with automotive-grade reliability standards. It complements other RL78 variants by offering specific memory configurations.
Consult the Renesas substitution guide for direct equivalents. Cross-reference pinouts and electrical characteristics carefully. Verify software compatibility if migrating from older RL78 models.
