Product details
Overview
R5F101SHAFB#10 from Renesas is a 128-pin, LFQFP-0.5 mm pitch, ultra-low-power 16-bit RL78/G13 microcontroller with 128 KB flash memory, 12 KB RAM, and no data flash. It operates from 1.6 V to 5.5 V, delivers 41 DMIPS at 32 MHz, and supports RTC, LVD, and multiple low-power modes (HALT/STOP/SNOOZE) for battery-powered industrial control and sensor interface applications.
For engineers reviewing the R5F101SHAFB#10 datasheet, R5F101SHAFB#10 pinout, R5F101SHAFB#10 application, or R5F101SHAFB#10 equivalent, key selection criteria include its 128-pin LFQFP package, absence of on-chip data flash, -40°C to +85°C industrial temperature grade (D), integrated 10-bit ADC (26 channels), real-time clock with calendar function, and support for UART, I²C, and CSI serial interfaces.
Technical Context
The R5F101SHAFB#10 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling 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 map spans 1 MB address space, with 128 KB code flash organized in 1 KB blocks and security features including block erase prohibition.
It integrates peripheral subsystems including an 8/10-bit A/D converter with internal 1.45 V reference and temperature sensor, 16-bit timer (16 channels), real-time clock with alarm and correction, watchdog timer, DMA controller (4 channels), and serial interfaces: up to 10 I²C/Simplified I²C channels, 4 UART/LIN channels, and 8 CSI channels - all configurable without external components.

FAQ
What is the operating temperature range for R5F101SHAFB#10?
The R5F101SHAFB#10 is rated for industrial operation from −40°C to +85°C (D grade). This specification is confirmed in the RL78/G13 datasheet Section 1.1 under "Operating ambient temperature" and applies specifically to part numbers ending in 'D' - which R5F101SHAFB#10 satisfies per its ordering code structure.
Does R5F101SHAFB#10 include on-chip data flash memory?
No, R5F101SHAFB#10 does not include on-chip data flash memory. Per the RL78/G13 datasheet Section 1.2 ("List of Part Numbers"), the second digit '1' in the part number indicates "Data flash is not provided". This distinguishes it from R5F100xxx variants, which carry '0' and include 4–8 KB of data flash.
What package type and pin count does R5F101SHAFB#10 use?
R5F101SHAFB#10 uses a 128-pin LFQFP package with 0.5 mm pitch, as defined in Table 1-1 (page 12) of the RL78/G13 datasheet. The 'FB' suffix in the part number explicitly denotes LFQFP-0.5 mm pitch, and the 'SH' prefix corresponds to the 128-pin variant within the RL78/G13 family.
Can R5F101SHAFB#10 operate from a 1.8 V supply?
Yes, R5F101SHAFB#10 supports operation from 1.6 V to 5.5 V, including 1.8 V. This is specified in Section 1.1 ("Features") of the datasheet under "VDD = single power supply voltage of 1.6 to 5.5 V", and verified across all RL78/G13 variants regardless of flash size or pin count.
How many analog input channels does R5F101SHAFB#10 support?
R5F101SHAFB#10 supports up to 26 analog input channels (ANI0–ANI25), as documented in the RL78/G13 datasheet Section 1.1 under "A/D converter" and confirmed in the pin configuration table for 128-pin products. All channels are accessible via dedicated analog input pins and share the 10-bit ADC with internal 1.45 V reference.
