Overview
R5F101AEASP#30 from Renesas is a 30-pin LSSOP-packaged 16-bit RL78/G13 microcontroller with 48 KB flash memory, 4 KB data flash, 3 KB RAM, and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode), designed for battery-powered industrial sensors and smart metering interfaces.
For engineers reviewing the R5F101AEASP#30 datasheet, R5F101AEASP#30 pinout, R5F101AEASP#30 application, or R5F101AEASP#30 equivalent, this device delivers verified 32 MHz CPU performance (41 DMIPS), integrated 10-bit ADC (26-channel), real-time clock with calendar, and LIN-capable UART-key selection criteria for cost-sensitive, low-power embedded control.
Technical Context
The R5F101AEASP#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz HS mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates on-chip high-accuracy ±1.0% oscillator (1–32 MHz selectable) and dedicated low-speed oscillator for watchdog and RTC.
Power management includes HALT, STOP, and SNOOZE modes; memory subsystem comprises 48 KB code flash (1 KB block size), 4 KB background-operable data flash (1M rewrite cycles), and 3 KB SRAM-with flash library RAM usage starting at FEF00H per documentation.

Does the R5F101AEASP#30 include data flash memory, and what is its endurance specification?
Yes, the R5F101AEASP#30 includes 4 KB of on-chip data flash memory. Its endurance is rated at 1,000,000 write/erase cycles (typical), with background operation (BGO) support allowing program execution during rewrites - a key feature documented in Section 1.1 of the R01DS0131EJ0380 datasheet.
What package type and pin count does the R5F101AEASP#30 use, and is it RoHS compliant?
The R5F101AEASP#30 uses a 30-pin plastic LSSOP package (7.62 mm, 0.65-mm pitch), identified by the "SP" suffix and "#30" tray packaging code. It is RoHS compliant and rated for industrial temperature range (−40°C to +85°C), as specified in Table 1-1 of the RL78/G13 datasheet.
Can the R5F101AEASP#30 support LIN bus communication, and which peripheral enables it?
Yes, the R5F101AEASP#30 supports LIN 2.x communication via its UART peripheral, which includes built-in sync-break detection and automatic baud rate adjustment. This capability is explicitly listed under "Serial interface" in Section 1.1 of the R01DS0131EJ0380 datasheet and requires no external transceiver for basic node implementation.
What is the minimum supply voltage and associated low-power mode current for the R5F101AEASP#30?
The R5F101AEASP#30 operates from 1.6 V to 5.5 V. In STOP mode with only RTC and LVD active, its typical current consumption is 0.57 μA - a value confirmed in the "True low-power platform" summary on Page 1 of the R01DS0131EJ0380 datasheet and validated across the A-grade temperature range.
