R5F100JEAFA#10 Renesas RL78/G13 16-bit Low-Power MCU 64KB Flash 32MHz LQFP-52

R5F100JEAFA#10 Product Overview

When selecting an MCU for general-purpose embedded applications that require more I/O and pin resources, designers typically focus on three things: low enough power consumption, rich peripheral interfaces, and sufficient pin count for system expansion. The Renesas R5F100JEAFA#10 from the RL78/G13 series was built for exactly that requirement. It features a 16-bit RL78 CISC core running at up to 32MHz with 41 DMIPS performance. Its true low-power platform consumes only 66μA per MHz during operation and just 0.57μA with only RTC and LVD active. Operating from 1.6V to 5.5V, it offers 64KB code flash, 4KB RAM, and 4KB data flash, with 48 I/O ports, 12-channel 10-bit ADC, and CSI, I²C, LINbus, UART/USART connectivity in a LQFP-52(10×10) package, making it ideal for industrial automation, consumer electronics, IoT edge devices, and building automation where pin resources and power are critical.

FAQ

Q: How is the power consumption?
A: It operates at just 66μA/MHz in run mode and 0.57μA in STOP mode with only RTC and LVD active — ideal for battery-powered or power-sensitive designs.

Q: What communication interfaces are supported?
A: CSI, I²C, LINbus, and UART/USART, plus 5-channel SPI and 6-channel I²C — covering most embedded peripheral connectivity needs.

Q: How does it differ from R5F100JEAFA#50?
A: Identical specifications and package; the primary difference is packaging — Tray for #10 vs. Full Carton for #50. Renesas lists #50 as the official replacement for #10.
