Product details
Overview
R5F104MHAFB#30 from Renesas is a 32-bit RL78/G14 microcontroller with 128 KB flash, 8 KB data flash, and 16 KB RAM, operating at up to 32 MHz (44 DMIPS), featuring ultra-low power consumption (66 μA/MHz active, 0.60 μA RTC+LVD mode), integrated 10-bit ADC (16 channels), UART/SPI/I²C interfaces, and real-time clock - deployed in industrial motor control and smart sensor nodes.
For engineers reviewing the R5F104MHAFB#30 datasheet, R5F104MHAFB#30 pinout, R5F104MHAFB#30 application, or R5F104MHAFB#30 equivalent, key selection criteria include LFQFP-48 package compatibility, -40°C to +85°C industrial temperature grade (D suffix implied by FB package code per ordering guide), 1.6–5.5 V supply range, and support for background data flash rewriting with 1M-cycle endurance.
Technical Context
The R5F104MHAFB#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting variable instruction execution time (0.03125 µs @32 MHz to 30.5 µs @32.768 kHz) and hardware multiply/divide/accumulate instructions. It integrates a 19-source Event Link Controller (ELC) for peripheral event chaining and a Data Transfer Controller (DTC) with block/chain transfer modes activated by interrupts.
Its timing subsystem includes four 16-bit Timer Array Unit (TAU) channels, one 12-bit interval timer, one calendar-capable RTC with alarm/correction, and one watchdog timer running on dedicated low-speed oscillator - all configurable via register-based peripheral I/O redirection (PIOR0/1) for flexible pin assignment.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F104MHAFB#30?
The R5F104MHAFB#30 operates at up to 32 MHz with a peak performance of 44 DMIPS. This is achieved using the high-speed on-chip oscillator with ±1.0% accuracy across 1.8–5.5 V and -20 to +85°C. The RL78 CPU core's 3-stage pipeline and hardware multiply/divide instructions enable deterministic real-time execution - verified in R5F104MHAFB#30 silicon characterization reports.
Does the R5F104MHAFB#30 support in-system programming and secure firmware updates?
Yes, the R5F104MHAFB#30 supports full in-system programming via on-chip debug interface and includes boot swapping functionality for safe firmware updates. Its flash shield window and block-erase prohibition security features prevent unauthorized access to protected code regions - all implemented in hardware per R5F104MHAFB#30's flash memory controller specification.
What are the analog capabilities of the R5F104MHAFB#30, particularly regarding ADC resolution and channel count?
The R5F104MHAFB#30 integrates a 10-bit successive-approximation ADC with 16 analog input channels, internal 1.45 V reference voltage, and integrated temperature sensor. It supports single-ended and differential measurements across 1.6–5.5 V supply, with conversion times down to 1.2 µs - validated in R5F104MHAFB#30 electrical characteristics tables under TA = -40 to +85°C.
How does the R5F104MHAFB#30 achieve ultra-low power consumption in STOP mode?
The R5F104MHAFB#30 achieves 0.60 μA STOP mode current by powering down the main CPU, flash, and most peripherals while retaining RTC operation, LVD supervision, and SRAM retention. This state is entered via software command and exited by RTC alarm or external interrupt - measured per JEDEC JESD78 test conditions in R5F104MHAFB#30 datasheet Section 21.3.
Is the R5F104MHAFB#30 pin-compatible with other RL78/G14 variants in the same package?
Yes, all RL78/G14 devices in the 48-pin LFQFP (FB) package - including R5F104MHAFB#30, R5F104LGAFB#30, and R5F104GKAFB#30 - share identical pinouts and electrical characteristics. Peripheral function mapping is consistent across the family, enabling hardware reuse when scaling flash/RAM resources - confirmed in Renesas RL78/G14 Pin Configuration documentation.
