Product details
Overview
R5F100ADASP#X0 from Renesas is a 30-pin, LSSOP-30 packaged RL78/G13 16-bit microcontroller with 48 KB flash memory, 4 KB data flash, 2 KB RAM, and industrial-grade -40°C to +85°C operation. It integrates a 32 MHz high-accuracy on-chip oscillator (±1.0%), 10-bit ADC (26 channels), RTC, UART/SPI/I²C interfaces, and ultra-low-power modes (0.57 μA in STOP with RTC+LVD). It targets battery-powered industrial sensors and smart metering front-ends.
For engineers reviewing the R5F100ADASP#X0 datasheet, R5F100ADASP#X0 pinout, R5F100ADASP#X0 application, or R5F100ADASP#X0 equivalent, key selection criteria include its LSSOP-30 footprint, 48 KB code flash with self-programming, 2 KB RAM allocation for real-time control tasks, and support for LIN-bus via UART - critical for cost-sensitive, low-power embedded systems requiring long-term firmware field updates.
Technical Context
The R5F100ADASP#X0 implements the RL78 CPU core with a 3-stage CISC pipeline, enabling 41 DMIPS at 32 MHz while maintaining sub-μA standby current. Its memory subsystem includes separate code flash (48 KB, 1 KB block size) and data flash (4 KB, 1M rewrite cycles, background operation), allowing concurrent execution and nonvolatile parameter storage without halting the CPU.
Peripherals are optimized for deterministic real-time control: dual UARTs (one supporting LIN 2.2), up to 16-channel 16-bit timers with input capture/compare, and an 8/10-bit ADC with internal 1.45 V reference and temperature sensor - all operating across the full 1.6–5.5 V supply range and industrial temperature grade.

FAQ
What is the maximum operating frequency and performance of the R5F100ADASP#X0?
The R5F100ADASP#X0 operates at up to 32 MHz using its high-accuracy on-chip oscillator, delivering 41 DMIPS of processing performance. Its RL78 CPU core uses a 3-stage pipeline and supports instruction execution times ranging from 0.03125 μs (high-speed mode) to 30.5 μs (ultra-low-speed 32.768 kHz mode), enabling flexible trade-offs between speed and power consumption in the R5F100ADASP#X0 design.
Does the R5F100ADASP#X0 support LIN bus communication?
Yes, the R5F100ADASP#X0 supports LIN bus communication through one of its UART channels, which is explicitly LIN-bus compatible per the RL78/G13 datasheet. This allows direct connection to LIN transceivers without protocol translation, making the R5F100ADASP#X0 suitable for automotive body electronics such as door modules and seat controllers.
What are the memory configuration and data retention capabilities of the R5F100ADASP#X0?
The R5F100ADASP#X0 includes 48 KB of code flash memory (1 KB erase blocks), 4 KB of data flash memory rated for 1,000,000 write cycles, and 2 KB of on-chip RAM. Data flash supports background operation (BGO), enabling concurrent code execution and nonvolatile parameter storage - a key capability for firmware resilience in the R5F100ADASP#X0.
What low-power modes are available on the R5F100ADASP#X0, and what is the lowest current draw?
The R5F100ADASP#X0 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws just 0.57 μA - the lowest operational current. This ultra-low quiescent current makes the R5F100ADASP#X0 well-suited for battery-powered applications requiring multi-year operation without maintenance.
Is the R5F100ADASP#X0 pin-compatible with other RL78/G13 variants in LSSOP-30 packaging?
Yes, the R5F100ADASP#X0 shares identical pinout and LSSOP-30 packaging (PLSP0030JB-B) with other 30-pin RL78/G13 members including R5F100AAASP#X0, R5F100AEASP#X0, and R5F100AGASP#X0. This allows drop-in replacement within the same memory/peripheral subset, simplifying design reuse and migration paths for the R5F100ADASP#X0.
