Renesas R5F100SLDFB#30

Overview

R5F100SLDFB#30 from Renesas is a 128-pin LFQFP (14 × 20 mm, 0.5-mm pitch), industrial-grade RL78/G13 16-bit MCU with 512 KB flash, 8 KB data flash, 32 KB RAM, and operation from −40°C to +85°C (D grade). It delivers 41 DMIPS at 32 MHz, consumes 66 μA/MHz active and 0.57 μA in RTC+LVD-only mode, and integrates UART, I²C, SPI, 16-bit timers, 10-bit ADC (26 channels), and real-time clock - deployed in smart metering and industrial sensor nodes.

For engineers reviewing the R5F100SLDFB#30 datasheet, R5F100SLDFB#30 pinout, R5F100SLDFB#30 application, or R5F100SLDFB#30 equivalent, key selection criteria include its D-grade temperature rating, 128-pin LFQFP package with 26-channel ADC support, integrated data flash with 1M rewrite cycles, low-power STOP/HALT/SNOOZE modes, and RL78 CPU core with 1 MB address space and on-chip debug.

Technical Context

The R5F100SLDFB#30 implements the RL78 CISC core with 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 512 KB code flash (1 KB block size), 8 KB background-operable data flash, and 32 KB SRAM - enabling simultaneous program execution and data flash rewriting.

Peripherals include up to 16× 16-bit timers, 1× real-time clock with calendar/alarm/correction, 1× watchdog timer, 2–4 channel DMA, 16× 10-bit ADC inputs (with internal 1.45 V reference and temperature sensor), and serial interfaces: 2–4 UART/LIN, 3–10 I²C, and 2–8 CSI (SPI-compatible). Power management features POR, LVD (14-level selectable), and multiple low-power modes.

FAQ

What is the operating temperature range for R5F100SLDFB#30?

R5F100SLDFB#30 is rated for −40°C to +85°C (D grade), qualifying it for industrial ambient environments. This specification is confirmed in the RL78/G13 datasheet Rev.3.80 Section 1.1 under "Operating ambient temperature" and applies specifically to all R5F100xxx D-grade variants including R5F100SLDFB#30.

Does R5F100SLDFB#30 include data flash memory?

Yes, R5F100SLDFB#30 includes 8 KB of data flash memory with background operation (BGO) and 1,000,000 write cycles (typical). This is verified in the RL78/G13 datasheet Rev.3.80 Section 1.1 "Data Flash Memory" and Table 1-1, where the "100" prefix denotes data flash presence and the "SL" variant maps to 512 KB/8 KB/32 KB configuration.

What package type and pin count does R5F100SLDFB#30 use?

R5F100SLDFB#30 uses a 128-pin LFQFP package with 0.5-mm pitch and 14 × 20 mm body size, as defined by the "FB" suffix per Figure 1-1 and Table 1-1 (page 12) of the RL78/G13 datasheet Rev.3.80. The "S" in "SL" indicates 128-pin count, and "FB" explicitly denotes LFQFP.

How many analog input channels does R5F100SLDFB#30 support?

R5F100SLDFB#30 supports 26 analog input channels (ANI0–ANI25) with 10-bit resolution, as specified in Section 1.1 "A/D converter" of the RL78/G13 datasheet Rev.3.80. This full channel count is enabled in the 128-pin package due to maximum I/O resource allocation.

Is R5F100SLDFB#30 pin-compatible with other RL78/G13 variants?

R5F100SLDFB#30 is pin-compatible with other 128-pin LFQFP RL78/G13 devices sharing the same "SL" base (e.g., R5F100SLAFB#30, R5F101SLDFB#30), as confirmed by identical pin configurations in Section 1.3.2 of the RL78/G13 datasheet Rev.3.80 - though functional differences (e.g., data flash presence) require firmware validation.
