Product details
Overview
R5F101LJAFA#30 from Renesas is a 64-pin LQFP-0.65mm, 16-bit RL78/G13 microcontroller with no data flash, 128 KB code flash, 12 KB RAM, and industrial-grade -40°C to +85°C operation. It delivers 41 DMIPS at 32 MHz, features ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD), and integrates 16-bit timers, 10-bit ADC (26 channels), UART, I²C, CSI, RTC, and DMA for embedded control in space-constrained industrial systems.
For engineers reviewing the R5F101LJAFA#30 datasheet, R5F101LJAFA#30 pinout, R5F101LJAFA#30 application, or R5F101LJAFA#30 equivalent, key selection considerations include its 64-pin LQFP package, absence of on-chip data flash, 128 KB/12 KB flash/RAM allocation, support for SNOOZE mode low-power operation, and compatibility with Renesas' RL78 toolchain and E2 studio IDE.
Technical Context
The R5F101LJAFA#30 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling configurable instruction execution time from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It supports multiple low-power modes-HALT, STOP, and SNOOZE-with dedicated LVD and POR circuits for robust industrial operation.
It integrates 16-bit timer arrays (up to 16 channels), a calendar-capable real-time clock with alarm and correction, 10-bit A/D converter with internal 1.45 V reference and temperature sensor, and serial interfaces including up to 10-channel simplified I²C, 4-channel UART/LIN, and 8-channel CSI-all operating across the full 1.6–5.5 V supply range.

FAQ
What is the flash memory configuration of the R5F101LJAFA#30?
The R5F101LJAFA#30 contains 128 KB of code flash memory organized in 1 KB blocks, with no on-chip data flash. This configuration supports substantial firmware size while eliminating data flash overhead-ideal for applications where parameters are stored externally or retained in RAM with backup power.
Does the R5F101LJAFA#30 support real-time clock functionality?
Yes, the R5F101LJAFA#30 integrates a full-featured real-time clock (RTC) with calendar support (99-year range), alarm interrupt, and clock correction function. It operates independently in STOP mode with only 0.57 μA current draw, enabling accurate timekeeping in battery-backed systems.
What low-power modes are available on the R5F101LJAFA#30?
The R5F101LJAFA#30 supports HALT, STOP, and SNOOZE modes. STOP mode draws just 0.57 μA with RTC and LVD active; SNOOZE enables background data flash writes while CPU is halted-providing optimal trade-offs between responsiveness, power, and firmware update capability.
Can the R5F101LJAFA#30 perform analog-to-digital conversion with internal references?
Yes, the R5F101LJAFA#30 includes a 10-bit A/D converter with up to 26 input channels and an internal 1.45 V reference voltage. This allows stable ratiometric measurements without external reference components-critical for precision sensor interfacing in varying supply conditions.
Is the R5F101LJAFA#30 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 64-pin LQFP-0.65mm package-including R5F101LJAFA#30, R5F100LJAFA#30, and R5F101LCAFA#30-share identical pinouts and electrical characteristics. This enables hardware reuse across firmware variants with differing flash/RAM configurations.
