Product details
Overview
R5F101SHAFB#30 from Renesas is a 128-pin LFQFP (14 × 20 mm, 0.5-mm pitch), data-flash-free RL78/G13 16-bit microcontroller optimized for ultra-low-power embedded control. It delivers 41 DMIPS at 32 MHz, features 128 KB code flash, 12 KB RAM, operates from 1.6–5.5 V, and supports -40°C to +85°C industrial ambient temperature (D-grade) - ideal for battery-powered sensor nodes and smart metering front-ends.
For engineers reviewing the R5F101SHAFB#30 datasheet, R5F101SHAFB#30 pinout, R5F101SHAFB#30 application, or R5F101SHAFB#30 equivalent, key selection considerations include its 128 KB flash / 12 KB RAM configuration, absence of on-chip data flash, D-grade industrial temperature rating, LFQFP-128 package with 0.5-mm pitch, and integrated peripherals including RTC, 10-bit ADC (26 channels), and multiple serial interfaces (UART, I²C, CSI).
Technical Context
The R5F101SHAFB#30 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode). Its memory subsystem includes 128 KB code flash organized in 1 KB blocks and 12 KB on-chip RAM, with no data flash memory - distinguishing it from R5F100x variants.
Power management includes HALT, STOP, and SNOOZE low-power modes, achieving 66 μA/MHz active current and 0.57 μA RTC+LVD retention current. Peripheral integration covers 16× 16-bit timers, 1× real-time clock with calendar/alarm, 1× watchdog timer, 10-bit A/D converter with up to 26 analog inputs, and 3× I²C/Simplified I²C channels - all operating across the full 1.6–5.5 V supply range.

Yes, the R5F101SHAFB#30 integrates a full-featured real-time clock (RTC) with calendar support for 99 years, alarm function, and clock correction capability. This is documented in the RL78/G13 datasheet Section 1.1 Features under "Timer" and verified in the peripheral listing for 128-pin D-grade devices. The RTC operates independently in STOP mode using a 32.768 kHz crystal.
What is the operating temperature range for the R5F101SHAFB#30?
The R5F101SHAFB#30 is rated for industrial operation from -40°C to +85°C (D-grade), as specified in the RL78/G13 datasheet Section 1.1 Features and confirmed by its part number suffix "D" in the ordering code structure. This qualifies it for deployment in factory automation, HVAC, and outdoor metering environments where extended thermal stability is required.
Which package type does the R5F101SHAFB#30 use?
The R5F101SHAFB#30 uses a 128-pin LFQFP package with 14 × 20 mm body size and 0.5-mm pin pitch, identified by the "FB" suffix in the part number and confirmed in Table 1-1 of the RL78/G13 datasheet. This package is RoHS-compliant and rated MSL3, supporting standard reflow soldering processes.
How many analog input channels does the R5F101SHAFB#30 support?
The R5F101SHAFB#30 supports up to 26 analog input channels for its 10-bit A/D converter, as stated in the RL78/G13 datasheet Section 1.1 Features under "A/D converter". This channel count is consistent across all 128-pin RL78/G13 variants and enables simultaneous acquisition from multiple sensors in industrial monitoring applications.
