Product details
Overview
R5F101MJAFB#30 from Renesas is a 32-bit RL78/G13 microcontroller with no data flash memory, housed in an 80-pin LFQFP (0.5-mm pitch) package, operating from 1.6 V to 5.5 V, delivering 41 DMIPS at 32 MHz and featuring ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD mode) for battery-powered industrial control and sensor interface applications.
For engineers reviewing the R5F101MJAFB#30 datasheet, R5F101MJAFB#30 pinout, R5F101MJAFB#30 application, or R5F101MJAFB#30 equivalent, key selection criteria include its 192 KB code flash, 16 KB RAM, 52-channel ADC (10-bit), dual UART/LIN support, and real-time clock with calendar function - all within an industrial-grade -40°C to +105°C temperature range.
Technical Context
The R5F101MJAFB#30 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting variable instruction execution time from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates a 12-bit interval timer, 16-bit timers (12 channels), and a calendar-capable real-time clock with alarm and correction functions.
Its peripheral set includes 3 CSI/SPI channels, 4 I²C channels, 2–4 UART/LIN interfaces, and a DMA controller with 4 channels enabling efficient data movement between SFRs and RAM in just 2 clocks per 8/16-bit transfer - critical for deterministic sensor aggregation and serial protocol bridging in resource-constrained edge nodes.

FAQ
What is the maximum operating frequency of the R5F101MJAFB#30?
The R5F101MJAFB#30 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. This frequency is fully supported across the full industrial temperature range (-40°C to +105°C) and supply voltage range (1.6 V to 5.5 V), with oscillator accuracy maintained at ±1.0% under those conditions.
Does the R5F101MJAFB#30 include data flash memory?
No, the R5F101MJAFB#30 does not include data flash memory. As indicated by the "101" in its part number (per Renesas RL78/G13 naming convention), this variant provides 192 KB of code flash only. Applications requiring non-volatile parameter storage must use external EEPROM or select the R5F100MJAFB#30, which includes 8 KB of data flash.
What package type and pin count does the R5F101MJAFB#30 use?
The R5F101MJAFB#30 uses an 80-pin LFQFP package with 0.5-mm pitch and 12 mm × 12 mm body size (RENESAS Code PLQP0080KE-A). The "FB" in the part number explicitly denotes LFQFP, and the "MJ" segment confirms the 80-pin configuration per the RL78/G13 ordering guide.
Can the R5F101MJAFB#30 operate in extended temperature environments?
Yes, the R5F101MJAFB#30 is rated for industrial operation from -40°C to +105°C, as confirmed by its "G" grade suffix in the full part numbering scheme. This makes it suitable for under-hood automotive modules, factory-floor controllers, and outdoor utility equipment where ambient temperatures exceed standard commercial limits.
How many ADC channels does the R5F101MJAFB#30 support?
The R5F101MJAFB#30 supports 52 analog input channels for its 10-bit successive-approximation ADC. These channels include dedicated pins and multiplexed functions across port groups, and the ADC features an internal 1.45 V reference and temperature sensor - enabling precise ratiometric measurements and on-die thermal monitoring without external components.
