Product details
Overview
R5F100SKAFB#V0 from Renesas is a 128-pin LFQFP-0.5mm MCU in the RL78/G13 family, featuring 256 KB flash, 8 KB data flash, 20 KB RAM, 32 MHz operation (41 DMIPS), and ultra-low-power modes (66 μA/MHz active, 0.57 μA RTC+LVD). It integrates 16-bit timers, 10-bit ADC (26 channels), UART/LIN, I²C, CSI, RTC, and operates from 1.6–5.5 V for battery-powered industrial control and sensor nodes.
For engineers reviewing the R5F100SKAFB#V0 datasheet, R5F100SKAFB#V0 pinout, R5F100SKAFB#V0 application, or R5F100SKAFB#V0 equivalent, key selection criteria include its 128-pin LFQFP package, integrated data flash with background operation, real-time clock with calendar/alarm, LIN-capable UARTs, and support for -40°C to +85°C industrial ambient operation.
Technical Context
The R5F100SKAFB#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It includes on-chip debug, self-programming with boot swap, and flash shield window security.
Power management features HALT, STOP, and SNOOZE modes; the LVD offers 14 selectable voltage detection levels with interrupt/reset options.

FAQ
What is the operating temperature range for the R5F100SKAFB#V0?
The R5F100SKAFB#V0 is rated for industrial applications with an operating ambient temperature range of -40°C to +85°C. This specification is confirmed in the RL78/G13 datasheet (R01DS0131EJ0380 Rev.3.80, Section 1.1), and the part number suffix "A" denotes this temperature grade. It does not support the extended -40°C to +105°C range offered by "G"-grade variants.
Does the R5F100SKAFB#V0 include an integrated temperature sensor?
Yes, the R5F100SKAFB#V0 includes an on-chip temperature sensor usable with the 10-bit ADC. As specified in the RL78/G13 datasheet (Section 1.1, "A/D converter"), the sensor is available only in HS (high-speed main) mode and provides calibrated readings referenced to the internal 1.45 V bandgap voltage - enabling system-level thermal monitoring without external components.
How many UART channels with LIN support does the R5F100SKAFB#V0 provide?
The R5F100SKAFB#V0 provides up to four UART channels, each supporting LIN bus protocol (LIN 2.2A compliant). This is documented in the "Serial interface" section of the RL78/G13 datasheet (R01DS0131EJ0380 Rev.3.80, Page 1), confirming LIN functionality across all UART modules - essential for automotive body electronics and distributed industrial control networks.
What is the maximum ADC resolution and channel count supported by the R5F100SKAFB#V0?
The R5F100SKAFB#V0 supports a 10-bit successive-approximation ADC with up to 26 analog input channels. The ADC operates across the full 1.6–5.5 V supply range and includes an internal 1.45 V reference and temperature sensor. These specifications are explicitly listed in the "A/D converter" subsection of the RL78/G13 datasheet (Section 1.1).
Is the R5F100SKAFB#V0 pin-compatible with other RL78/G13 128-pin variants?
Yes, the R5F100SKAFB#V0 shares the same 128-pin LFQFP (14 × 20 mm, 0.5 mm pitch) mechanical footprint and pinout with all other RL78/G13 devices in the "S" package group (e.g., R5F100SHAFB#V0, R5F100SJAFB#V0, R5F100SLAFB#V0). Pin compatibility is guaranteed per Renesas' package documentation (PLQP0128KD-A) and verified in Table 1-1 of the datasheet (Page 12).
