Product details
Overview
R5F100LHAFB#30 from Renesas is a 64-pin LFQFP (10 × 10 mm, 0.5-mm pitch), industrial-grade RL78/G13 16-bit MCU with 128 KB flash, 8 KB data flash, 12 KB RAM, and true low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD). It integrates 16-bit timers (16 ch), 10-bit ADC (26 ch), UART/LIN, I²C, CSI, RTC, and operates from 1.6–5.5 V across –40°C to +105°C - deployed in motor control subsystems, sensor fusion nodes, and smart HVAC actuators.
For engineers reviewing the R5F100LHAFB#30 datasheet, R5F100LHAFB#30 pinout, R5F100LHAFB#30 application, or R5F100LHAFB#30 equivalent, key selection criteria include its 64-pin LFQFP-0.5mm package compatibility with high-density industrial PCB layouts, guaranteed 105°C operation for under-hood or enclosed thermal environments, and integrated LIN physical layer support for automotive body electronics integration.
Technical Context
The R5F100LHAFB#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (@32 MHz HS oscillator) to 30.5 μs (@32.768 kHz subsystem clock). Its memory subsystem includes 128 KB on-chip code flash (1 KB block size, security lock), 8 KB background-operable data flash (1M rewrite cycles), and 12 KB SRAM - enabling robust firmware updates and real-time logging without halting execution.
Peripherals are tightly coupled to power management: DMA supports 4-channel transfers with 2-clock latency between SFR and RAM; the 10-bit ADC features internal 1.45 V reference and temperature sensor; and the RTC provides calendar-based timekeeping with alarm and auto-correction. All operate within the same ultra-low-power HALT/STOP/SNOOZE modes that define the RL78/G13 platform.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101LHAFB#30 | No data flash (0 KB); identical core, peripherals, and package. | Not suitable for field-upgradable firmware or persistent parameter storage. | Select when boot code is immutable and configuration is stored externally or in external EEPROM. |
| RA2A1GBM20FHI00 | Arm® Cortex®-M23 core, 128 KB flash, 16 KB SRAM, 24-bit sigma-delta ADC, 105°C rating. | Better suited for higher-precision analog acquisition and cryptographic operations; larger code footprint. | Choose when migrating to Arm ecosystem, requiring secure boot, or needing >10-bit ADC resolution for current sensing. |
Compared with R5F100LHAFB#30, R5F101LHAFB#30 removes data flash to lower cost and simplify programming flow, while RA2A1GBM20FHI00 trades RL78's ultra-low-power determinism for Arm-based scalability and enhanced analog performance - making each viable only where their specific memory, architecture, or peripheral trade-offs align with system requirements.

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F100LHAFB#30?
The R5F100LHAFB#30 operates up to 32 MHz using its high-speed on-chip oscillator. At this frequency, active current consumption is 66 μA/MHz - resulting in approximately 2.1 mA total at 32 MHz with all peripherals disabled. In STOP mode with only RTC and LVD active, it draws just 0.57 μA, enabling multi-year battery life in intermittent-sensing applications.
Does the R5F100LHAFB#30 support LIN communication, and what hardware resources are required?
Yes, the R5F100LHAFB#30 supports LIN 2.2 communication via its UART peripheral with built-in LIN break detection and sync field generation. No external transceiver is needed for basic LIN node functionality - the MCU drives the bus directly through an open-drain output pin configured for LIN PHY level. Full compliance requires external passive components per ISO 17987-4.
How many analog input channels does the R5F100LHAFB#30 provide, and what reference options are available?
The R5F100LHAFB#30 provides 26 analog input channels across P20–P27, P50–P57, and P60–P67. It supports VDD as ADC reference, internal 1.45 V bandgap reference (selectable only in HS mode), and external reference via AVREFP/AVREFM pins - enabling flexible measurement ranges from 0–VDD to high-precision ratiometric sensing.
Is the R5F100LHAFB#30 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 64-pin LFQFP-0.5mm package (e.g., R5F100LCAFB#30, R5F100LLAFB#30) share identical pinouts and electrical characteristics. This allows drop-in replacement across memory variants (16–512 KB flash) without PCB redesign - provided software accounts for differences in flash size, data flash presence, and RAM allocation.
What debug and programming interfaces are supported by the R5F100LHAFB#30?
The R5F100LHAFB#30 supports on-chip debugging via the single-wire SWD interface using pins P11 (TOOLRxD) and P10 (TOOLTxD), compatible with Renesas E2 emulator and standard J-Link tools. It also supports self-programming via the on-chip bootloader, enabling firmware updates over UART, I²C, or CSI without external programmers.
