Overview
R5F101AAASP#30 from Renesas is a 30-pin LSSOP-packaged RL78/G13 16-bit microcontroller with 16 KB flash, 2 KB RAM, and no data flash memory, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power HALT/STOP/SNOOZE modes (0.57 μA RTC+LVD), 10-bit ADC (6 channels), and integrated real-time clock - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F101AAASP#30 datasheet, R5F101AAASP#30 pinout, R5F101AAASP#30 application, or R5F101AAASP#30 equivalent, this page delivers verified electrical specs, package mapping, functional role in low-voltage embedded control, and validated alternative options for design continuity and supply resilience.
Technical Context
The R5F101AAASP#30 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates on-chip power-on-reset (POR), voltage detector (LVD) with 14 selectable levels, and a dedicated low-speed on-chip oscillator for watchdog timer operation.
It provides 8-channel 16-bit timers, one 12-bit interval timer, one calendar-based real-time clock (RTC) with alarm and correction functions, and serial interfaces including 2–4 UART/LIN channels, 2–8 CSI (SPI-compatible) channels, and 3–10 I²C/Simplified I²C channels - all configurable without external timing components.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F101AAASP#30?
The R5F101AAASP#30 operates at up to 32 MHz with a measured performance of 41 DMIPS. This benchmark reflects its RL78 CPU core's 3-stage pipeline efficiency and instruction mix optimization - enabling real-time control tasks such as motor commutation or sensor fusion without external acceleration. The R5F101AAASP#30 achieves this while maintaining ultra-low active current (66 μA/MHz).
Does the R5F101AAASP#30 include data flash memory, and how does that affect firmware design?
No, the R5F101AAASP#30 does not include data flash memory - unlike the R5F100xx variant which provides 4 KB. This means parameters, calibration values, or event logs must be stored in external EEPROM or SRAM with backup power. Firmware design avoids self-reprogramming of non-volatile user data, simplifying flash management but requiring external non-volatile storage for field-updatable configurations.
What are the supported low-power modes on the R5F101AAASP#30, and what is the lowest achievable current draw?
The R5F101AAASP#30 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws just 0.57 μA - verified across -40°C to +85°C. This enables multi-year operation on CR2032 batteries in wireless sensor endpoints. HALT mode consumes 1.23 μA (typ.) with CPU halted but peripherals active, offering intermediate power savings.
Can the R5F101AAASP#30 operate from a single 1.8 V supply, and what peripherals remain functional at that voltage?
Yes, the R5F101AAASP#30 supports operation down to 1.6 V, so 1.8 V is fully within specification. At 1.8 V, all core functions - including 32 MHz operation (with high-speed oscillator), 10-bit ADC (6 channels), RTC, UART, and I²C - remain fully functional. The internal voltage detector (LVD) also operates reliably, providing reset/interrupt capability across the full 1.6–5.5 V range.
Is the R5F101AAASP#30 pin-compatible with other RL78/G13 variants in the 30-pin LSSOP package?
Yes, all RL78/G13 30-pin LSSOP variants - including R5F100xxASP#30 and R5F101xxASP#30 - share identical pinouts and package dimensions (PLSP0030JB-B). This allows direct substitution in existing layouts when migrating between flash/RAM configurations or adding data flash, provided firmware accounts for memory map differences and peripheral enablement.
